Large-scale PV concession bidding will start

2010-06-26T09:43:00.002+08:00

Large-scale PV concession bidding will start

Most plants can all participate in the concession tender this case "lose out"

Because of the world's largest PV market - ahead of the German consumer market demand, China and Taiwan PV companies in the third quarter continued strong orders. It is noteworthy that China will start in the third quarter of 2010, eight provinces of the west concession bidding 280MW PV case and 50MW solar thermal power concession bidding case, the size of 10MW to enlarge several times higher than in 2009, is expected to build over two years completed, field operating time was 25 years.

We believe that, due to strong demand in overseas markets in 2010, component manufacturers repeat in 2009 the case of Dunhuang concession bargain should not happen, so winning this than the 2009 price would be picked up 1.09 yuan, in order to maintain a reasonable manufacturer return on investment is estimated at 1.1-1.3 yuan. We believe that most plants can all participate in the concession tender in this case some sort of relief. We expect the Chinese PV market in 2010 up to 300MW.

In addition, we expect continued increase in production capacity, making the price of polysilicon still test a low space. The current market price of polysilicon only stable at 50-55 dollars, is expected to offer the third quarter will continue to maintain the status quo, offer long-term polysilicon will continue dropping. A large number of shares in listed companies involved in most of polysilicon production is facing a shortage of cost-competitive, is not involved in short-term opportunity.

It is noteworthy that investors the world's largest PV market in Germany early in 2011 continues to lower its rates after the subsidy impact on demand worries, Jiashang the euro will also adversely affect Nokia earnings photovoltaic business, we maintain photovoltaic industry "neutral" rating.

Investment Recommendations

Investment direction in 2010, A shares the upstream polysilicon production costs are still competitive advantages in the polysilicon under the offer have an opportunity to continue dropping, it still isn'ta good opportunity. Component in photovoltaic cells, promising research can provide low-cost solutions to enterprises, the high-powered three-An optical concentrator technology and downstream integration of CSG's previous development strategy are more likely, with the results of other Haitong Group Support has also to note that we also optimistic about the key production processes necessary equipment, supplies (such as silicon wafer cutting fluid cutting required) and BOS components (such as photovoltaic power inverter), the relative stability of its huge profits, is the better investment direction We like Oak shares, shares of Wing Shun, Dragon Optical. Light and heat generating part, Higashiyama Precision shares with three flowers are light and heat has been involved in the system, with space themes speculation.

Siemens speeds up distribution of new energy

2010-06-26T09:31:00.002+08:00

Siemens speeds up distribution of new energy

Siemens Energy Corporation (Siemens Energy) has the green energy companies from the Ital receipt of an order will be Apulia region of Italy (ApuliaregionofItaly) construction of 15MW of solar PV power plant. In addition to this project design and engineering services, Siemens will also provide energy power inverter, transformer, medium voltage equipment and control systems, and is responsible for the establishment of power stations.

Investment Advisor in the new energy industry chief researcher Jiang Qian pointed out that this is the third time in recent Siemens layout of the new energy field, by the end of May, Siemens Solar thermal energy has been put on the professional company Archimede Solar Energy SRL's ownership from 28% to 45%. In addition, Siemens has announced early in March with the Carbon Trust Company, High Tide with investment in tidal power generation company.

This is with the current global energy investment in the new line of new trends. Investment adviser in the latest release of "2010-2015 China Renewable Energy Market Analysis and Forecast of Investment Report" shows that the financial crisis, because the concept of progressive enjoys popular low-carbon, combined with national government support, the global number of large enterprises have joined or expanded investments in new energy field, which includes Westinghouse, Intel, Alstom, Nokia Siemens, General Electric and so on. Large enterprises have entered, how the new energy of such a sunrise industry has attracted the attention of all walks of life. For enterprises, means that an expansion of its development strategy; and the industry is concerned, it means the appearance of the development of a greater driving force.

Jiang Qian pointed out that, as a global engineering giant Siemens have long tentacles reach into new energy areas, but in the past the layout more concentrated in the areas of wind power. Siemens fan business in 2008 achieved sales of 19 billion euros, or about a quarter of total sales of Siemens. The recent solar and tidal power generation in the areas of distribution, indicating Siemens Wind Power for the new energy other than the sub-sector increased attention, and look forward to a slice of them.

To light and heat generation, for example, though from the domestic point of view, the past few years with several leading enterprises led the field of photovoltaic rising investment boom, relatively speaking, solar energy utilization in the other important forms of light and heat for power generation still in its infancy. However, from a global point of view, the momentum of light and heat generating no less than the PV. Currently running the international solar thermal power generation capacity of over 660MW, construction project more than 2000MW, the development prospects have been looking on.

The development tendency of solar industry

2010-06-25T17:18:00.001+08:00

The development tendency of solar industry

1, experts believe that "building integrated solar energy is the future trend"

In recent years, energy efficiency and low wind blowing in the background, building energy conservation has become a focus of attention of the community in general. Related statistics show that China's building energy consumption to 30% of the total energy consumption, floor space heating energy consumption of unit 3 times for developed countries. Each year about 95% of new construction in high-energy construction. Therefore, the construction industry to improve the level of energy saving, low-carbon economy to improve the overall level of significance.

In addition, research also shows that in 2009 solar water heaters and hot water systems nationwide total reserves amounted to 145 million square meters. By ordinary market price of the coal, equivalent to savings of 22.5 billion yuan; by commercial electricity market prices to calculate the average, the equivalent of saving 56 billion yuan. While 145 million square meters of collector area, 44.51 million tons of carbon dioxide emissions a year. However, when mobile phones, home appliances, automobiles, increasing the penetration rate is high, in sharp contrast to the urban households in the domestic solar energy products, but really spend very little.

Even the lowest threshold of penetration of solar water heaters are far behind the city gas and electric water heater market growth rate, not to mention the significant energy-saving environmental protection, building-integrated solar energy. Of particular note is that while solar energy to rural areas to fire a handful of solar energy in rural areas, but the urban high-rise building of solar energy has been slow.

From the present situation of the localities in the integration of solar energy and construction is still a lack of unified planning and standards. To promote the development of building integrated solar energy and the state in 2007 was set up solar power Norit industry's only national housing industry base, three years to promote solar power Norit has been integrated with the construction of residential projects 34 million square meters, the equivalent of creating a completely new type of low carbon residential solar city.

Industry experts point out that the future course of construction planning, shall give special consideration to energy-saving elements, such as solar water heaters should be reserved for the interfaces. On the other hand, solar energy into the city construction, construction costs will increase, so one needs to reduce costs to enhance the scale of industrialization, the government introduced preferential policies and the need to be supported.

2, speed up the development of PV industry trend

In recent years the rapid development of the international PV, 2007, newly installed global solar capacity 2826mwp, which accounts for about 47% in Germany, Spain, about 23%, Japan 8%, the U.S. accounted for about 8%. In 2007, the solar photovoltaic industry chain, a large number of investment focus to the elevation of the new capacity. In addition, the solar PV business in 2007, the amount of loan financing increased by nearly 10 billion U.S. dollars, making the industry have been expanding. Although the financial crisis, Germany, Spain's efforts to support solar photovoltaic power generation has decreased, but other countries, policy support has increased year by year. Japanese government in November 2008 issued a "universal plan of action for solar power" to determine the amount of solar power development goals by 2030 is to achieve 40 times in 2005, and in 3-5 years, will drop the price of solar system to the current half. 2009, a special arrangements 30 billion yen in grants, special to encourage solar battery technology development. September 16, 2008, the U.S. Senate adopted a package of tax cuts, which will be photovoltaic industry's tax cuts (itc) 2-6 years of renewal. China's solar energy resources are very rich theoretical reserves of 1.7 trillion tons of standard coal per year. The potential of solar energy development and utilization of resources is very broad. China PV power industry started in the 20th century, 70s, 90s into the mid period of steady development. Solar cell and module production increased steadily year by year. After 30 years of effort, has ushered in a new stage of rapid development. In "Bright Project" pilot project and the "transmission to the village" projects of national projects and the powerful driving force in the world PV market, China's rapid development of photovoltaic power generation industry.

Development of domestic solar energy industry – setting water heater as an example

2010-06-25T17:14:00.002+08:00

Development of domestic solar energy industry – setting water heater as an example

With the increasing global tensions of traditional energy supply, new energy is not only sought after by many companies, but also by the state and governments at all levels attach great importance to the solar industry in particular, which has become widely accepted. According to Solar Energy Association released the latest data showed the country's output of solar water heaters to 30% annual growth rate in 2009, annual output of solar water heater break 40 million square meters, accounting for 50% of the world, retention capacity of 145 million square meters, accounting for 70% of the world's total, China has become the world's largest solar water heater producer and user countries. Norit only force a company's annual promotion of collector area installed on an area equal to the sum of the entire European Union, North America twice. However, nearly 6,000 domestic solar water heater companies, real own R & D capabilities and production scale of enterprises less than 20, the rest are mostly no-name brands and some local small businesses, and even many small family-owned business. These small enterprises were forced to survive and competitive pressures, backward production technology, quality management, confusion, product testing has been imperfect, and even cut corners, dumping and other serious impact on the reputation of the act, leading solar energy market order and chaos, there are many problems Some enterprises even faced a new crisis.

1, the industry standard is too low, mixed enterprise Yulong

The current industry standard solar water heater only a handful of GB/T19141-2003 "domestic solar hot water system technical conditions", GB/T18708-2002 "domestic solar water heating system thermal performance tests", etc., on the one hand the national standard is too low, such as the national standard only requires the pressure of the water heater capacity, did not make provisions for corrosion resistance, while the welds particularly susceptible to corrosion leaks; the other hand, lack of industry standards, such as the national standard on outdoor piping does not make the relevant provisions The pipes were frozen in winter the situation occur.

Industry standard is too low makes the solar energy industry quite a mixed bag, enterprise quality uneven. Solar water heater industry in China has not implemented the production license system, also without going through 3C compulsory certification. In the case of imperfect standard, many companies do not blend into one production qualification. The threshold for the industry's low barriers to enter the number of enterprises in this area is not part workshop-style company is able to as "tailor-made shoes," as customized solar water heater, product quality and after-sales service are difficult to guarantee.

2, a price war intensified crisis, the adverse long-term development

High homogeneity in the field of solar water heater, there is no obvious advantage, not only the core technology of the enterprise choice of lowering production costs to deal with price wars. Some enterprises are often the raw materials used to produce low prices and then sold at low prices. This will not only further aggravated the cruelty of competition, but also so that there is some leakage of solar water heaters, non-Sheung Shui, a lot of pressure and poor quality.

In a "consumer use of solar water heaters in China Investigation Report" shows that consumer satisfaction with the solar water heater industry is low, 41.5% of users say very satisfied, most of which reflect the solar water heater products of poor quality, after-sales service with no or low technology content products and so on, even the consumers reflected just bought a water heater is only one day, which the water is leaked out.

"The market is too small, competition and too much." Of the original solar technology company in Hubei Fei Yang Chen Yang sales manager admitted, in the face of menacing tide of competition, in addition to cut-off than no other choice. According to relevant statistics, at present nearly 8 percent of the solar water heater companies have different degrees of sales decline, inventories and other issues, many of them fly like Hubei, solar energy technology company that Yang was forced to stop production of enterprises.

Industry analysis, solar water heater business in recent years the rapid increase in production capacity significantly increased, but the market has not expanded accordingly.

Meanwhile, the weather impact, solar water heaters consumer demand by a certain degree of inhibition. Many companies compete for a bowl, will grab badly beaten, many companies would go bankrupt, discontinued.

3, the low level of brand, brand should be strengthened

"Many of the small enterprises have ceased production of the entire solar industry is a good thing." Chinese Academy of Sciences Guangzhou Institute of Energy Research Fellow Dr. Xu Gang that these low-technology, poor product quality solar products are out of the sound development of the whole industry is a positive significance. For the future direction of development of solar energy companies, industry experts generally agreed that while in the field of developing products, building brand is a priority. "Solar water heater companies in order to win in the fierce competition, only to start from the branding."

As industry leaders, since its inception in 2001, power Norit has been uphold the "responsibility to do create the world famous Sunshine," the purpose of all paid, low-key forward. They not only introduced the world's advanced solar technology in Germany, but also for the digestion, absorption, re-innovation, mastered the core technology of solar energy, even the Germans strict style of work applied to the production and service in every detail, widely by consumers The imperial gaze.

Norit adhering to scientific and technological innovation ability, while successively with Tsinghua University, Shandong Architecture University, and many other well-known to start college wide cooperation with enterprises, have taken up the banner of industry innovation. Which force Norit and Shandong Architectural University to complete the "shallow solar and geothermal energy use in the construction of key technology development and application of" project, implemented solar energy solar energy, shallow geothermal energy in the building the perfect combination, and get "2009 National Science and Technology Progress Award", also Weili Norit solar energy and building integrated expert added the name of a splendid touch.

At the same time, has been committed to leading the industry right direction to go in the strength of Norit lead the forefront of industry services. In addition to "creating the first service brand in China solar industry," the Declaration, but also launched the "one-dimensional, three-wide, nine-free" and "sunshine angel 139, Gold Service". At the same time, the country launched a 15,000 solar rescue center, there is no all-weather service for all maintenance and repair of solar water heaters.

Power Norit relevant responsible person said, solar energy industry is a sunrise industry, it's every step of the development is to have people to improve the environment, energy conservation is full of confidence and expectations. However, during the inevitable development of the industry problems, like shuffling through the Ebb Tide, the core competitiveness of enterprises did not definitely out, left behind is in the brand, technology, channels and other aspects of the enterprise-specific advantages.

Solar industry trends and prospects - the development of overseas solar energy industry

Solar as a new energy, the environment, global warming, more and more attention in various countries. Recently Expo, schematic to build a theme pavilion "Sun City" and dreams, such as the China Pavilion is a landmark of Shanghai World Expo on the roof flashing. In addition to the roof, the park road sides and Expo Village, a variety of photovoltaic power generation device will be large-scale applications. This is not only interpreted the image of Shanghai World Expo Science and Technology, green ideas, but also a vivid reflection of China's response to climate change, efforts to improve the energy structure. Therefore, the study of domestic solar energy industry under state of development, the Development Trends of great practical significance.

1. the development of overseas solar energy industry

Japan, Germany and the United States is to promote the most powerful solar power system state. Data show that in 2010 the EU hopes to install 3GW of photovoltaic power generation device, about 2030 to 200GW. The United States is expected to total installed PV power in 2020 reached 36GW. Japan plans to install approximately 2010 5GW.

Implemented in 1994 in Japan, "Asahi seven-year plan" has installed nearly 70,000 solar roofs by 2010 to install one million solar roofs. Germany in 2000 by the Renewable Energy Law to purchase a fixed discount price to encourage renewable energy, and in April 2004 and further supplemented and amended Renewable Energy Act, 2004, making Germany a substantial increase in PV power system equipment, and one stroke over Japan the world's largest installation of photovoltaic power generation system area. According to data provided Solarbuzz, 2004, Germany installed capacity of photovoltaic power generation system 361MW, up 152%, accounted for 39% of the global total; Japan to 278MW of installed capacity accounted for 30% of the world. Germany and Japan accounted for a global installed capacity of 2 / 3. At present China's battery products are mainly exported to the two countries. Million in 1997, the United States announced plans roof plans by 2010 to install 1 million rooftop photovoltaic and solar thermal systems.

Over the past decade, with the significant increase in world demand for PV market, coupled with large-scale manufacturing technology continues to improve and promote the rapid development of the world photovoltaic industry, photovoltaic cell production from 1995 to 78.6MW, up to 2005 of 1727MW, average annual growth rate reached 32.4%. Can be expected in the next 15 years the world will keep its annual PV production capacity of more than 20% growth, and even more optimistic estimate, by 2010, global solar production will grow by 4 times, 3 times sales growth, profit growth of 3 times.

World PV cell manufacturing mainly in Japan, Germany, the United States, Spain and other developed countries, including Japan's 2005 production of photovoltaic cells to 833MW, the world PV market share accounts for almost half of mainland China into the world's photovoltaic manufacturing 10 big country, with 2005 production of photovoltaic cells 128MW, listed fourth in the world, accounting for 7.4% of world market share.

This year in May, for the Tunisian Ministry of Industry of renewable energy, Secretary of State announced at a news conference: In 2009-2014 the president on energy and environment program areas, the conflict developed Prosoles plan, expected by 2014 to at least 5000 housing installation of solar PV installations, the Government and the suddenly the power companies will offer a number of incentives to encourage residential use of photovoltaic power generation industry.

Chuxiong: Promoting the development of photovoltaic energy

Recently, Jing Kun Yu successful instrument to a new green energy Chuxiong 4 MW PV power plant EPC turnkey services, which will also apply here with independent intellectual property instrument green energy efficient 250 kW PV power inverter.

Chuxiong rich in tourism resources with the economic development in recent years, demand for energy is growing. But the conventional thermal power project seriously pollute the environment, therefore, the local government will turn their attention to solar energy.

"Cost and grid, which spans a career in solar power are two problems to solve the two problems One of the key elements of the key device in the power inverter on." Jing-yee, said Guo Wenjie, general manager of green energy.

According to reports, solar energy conversion rate is not high, average about 15%, and the solar cells must generate the DC into AC power inverter should be used for civilian and production, in this transition process will inevitably part of the energy loss. Therefore, the energy conversion efficiency inverter PV system determines the energy conversion efficiency and return on investment. If the energy conversion efficiency is low, it means the power system needs to be equipped with more battery life, greatly increased the costs, otherwise cost.

Occupy high-power photovoltaic inverter system cost ratio of 10% -15%, and a higher technological content, currently the world's leading SMA occupies 44% market share, many domestic enterprises do not own photovoltaic R & D and production capacity need to import from abroad, which further increases the already high cost of electricity.

Guo Wenjie said that in June this year, Beijing Miriam Green Energy JYNB-500KHE 500KW inverter power efficiency through the national "Golden Sun" certification, including environmental testing, EMC testing, performance testing. Posted by certified product allows the "Golden Sun" certification mark. It is reported that, in addition to external validation by the domestic market can be recognized by the World Bank project.

Volkswagen electric vehicles pursue low-cost with high public return by abandoning battery

"German government now did not make any Guli to buy electric autocar, China in this regard is running away with the forefront." At the recent Da Zhong Dian Qudongjishu exchange Hui Shang, the mass of technical experts from Germany to China New Energy car full of praise to encourage policies. In the mass popularization of electric vehicles globally ambitious plan, China has played a supporting role. 2013, the public electric vehicle production in the world, China has become the ideal market for electric vehicles in the test base.

According to the mass of technical experts, China's subsidies to buy electric cars up to 6 yuan (6,500 euros), which is a higher figure. In Europe, Denmark, as the voice of the most popular electric car country, tax relief for up to 30,800 euros, Britain, France and Spain up to 6,000 euros, Portugal is € 4,500; in Asia, second only to Japan, China, the amount of subsidy, which cycling subsidies up to 11,000 euros.

China's market capacity is far from comparable in Japan and Europe, which is the general public to promote electric cars plan to China as the first choice for an important reason. In this exchange meeting, the public has brought 5 with a new technology for future models. Including Up electric concept car, golf and Long Yat electric vehicles, and the public with Tongji University to develop new leaders Yu hybrid fuel cell vehicles and the Touareg.

To electric vehicle, for example, the car driven by a motor, the maximum power of 85 kW / 115 hp, continuous output power of 50 kW / 69 hp and maximum torque of 270 cattle • meters. Drive vehicle is the energy stored in the capacity of 26.5 kWh lithium-ion battery, the battery component of the weight of 315 kg. The car from rest to 100 km per hour acceleration time of just 11.8 seconds, the maximum mileage up to 150 km.

Golf electric vehicle using an integrated electric drive system, its core components, including weighing about 80 kg of the motor and transmission and differential. Energy management through the integrated drive system for high voltage pulse inverter. The power inverter integrates a DC / DC converter with 12V car power supply and charging devices together constitute a set of integrated drive unit.

Although the public electric vehicle technology in the forefront of the world, but the most polluting electric car - battery manufacturers, he was the general public to give up. Earlier, China's executive vice president of public Sui Zhang said the new, to purchase car batteries in China. The public have signed a Memorandum of Understanding with the BYD plans to cooperate in the battery area and is close attention to the domestic automotive battery production line building. Battery manufacturing and recycling process based on the high pollution, many multinational companies and battery manufacturers are used to establish a joint venture or global sourcing approach, to get the car battery. This of course is in line with corporate and national environmental policy is best to consider, and the determination not to form part of the production of pollution and environmental damage, has been the consensus of the world's multinational corporations.

Currently the highest performance, the most stable car battery is a lithium ion battery. According to the general public that the Chinese is one of the most important producing areas of lithium. Conservative estimates, the global lithium reserves in 2050 will consume 51%. This also means that if can not find a better raw material for the manufacture of batteries, electric car battery supply will be a problem in the future, while the environmental damage caused by mining, combined with the battery, the formation of the pollution of coal power generation, electric vehicles popular may also bring about various environmental problems.

The development of solar energy has great business opportunities in the EMS field

In the recent global economic downturn, the electronics industry is also not spared. By 2010, the global economy is expected in Asia (primarily China and India), led by growth of 3%, the electronics industry is also expected to bounce back. Global economic recession caused a great demand suppression. But once the situation improves, companies and individuals will begin to purchase new electronic equipment and replace old equipment, which will promote the OEM production. Therefore, the electronic manufacturing services (EMS) industry will experience a lot more from the OEM manufacturers requirements.

Needless to say, the world to clean and renewable energy development trends show that the solar industry, great development potential, but the industry has faced in 2009 was also the biggest challenge. At that time, the Spanish government cuts support for further expansion, further down the price drop from 2008 after more than 30%. Earlier this year, in 2009 global demand plan can only reach about 3.5GW, compared with 2008 decreased by about 35%. in 2009, the German market by filling the gap left by Spain, full use of over-supply by the declining cost trends and factors such as the reality.

2010, global demand to reach 8.34GW. However, the global solar energy industry continued oversupply of the market may return a negative impact on normal growth line. In 2009, Spain decided to install only the highest 500MW solar power station, the German took over the development of solar energy industry, banner, self-confidence to lead the European solar market. This year, Germany, Spain and Italy hope to win 83% of Europe 88% market share.

Rest of the world are also underway to develop solar energy. California leads the U.S. by the fast development in 2011, the small solar power station is expected to become the largest market.

China will become the solar manufacturing center. By 2012, its output will account for 32% of global production. In the next 5 years, with the rise of full-fat new markets, China and India will eventually become a hotbed for solar energy market.

Clean Energy

Solar energy (photovoltaic or PV) battery means reducing dependence on fossil fuels, thus helping to reduce greenhouse gas emissions. For many years, solar energy has been the need for remote power supply of choice for industrial applications. Site and the use of solar energy but also to achieve some local power, that is, power does not require long-distance delivery by significantly reducing the transmission and distribution losses. Solar has also been widely used in traffic signals, such as coastal navigation buoys, lighthouses, road signs on the tower or building more and more aircraft warning lights and road traffic warning signals. Solar also for communications, TV and GPS satellite power supply.

Greatest advantage of solar energy is very reliable and require little maintenance. The production of solar energy systems also in the manufacturing, distribution, installation and maintenance to create new jobs. In addition to industrial centers, the wide spread of solar energy will create new employment opportunities.

EMS business opportunities

Expertise through the application of existing solar module assembly, EMS companies face value in the solar market showing a golden opportunity.

Solar inverter market price is expected to be lower

The continuous development of human society, along with more energy consumption, thus finding new energy sources become an urgent task. It is necessary to maintain the development of industrial economy, but also reduce the "carbon" emissions, an important way to increase the development and utilization of solar energy and other new energy sources. In response, countries around the world have increasing input solar power to replace oil, coal and other traditional energy sources.

Among the many renewable energy, solar energy received by the concern, the global wave of solar power is off. Developed countries, the United States plans to make the 2025 renewable energy accounted for 25% of the total electricity supply; to 2020, Japan's solar power generation capacity will reach about 20 times in 2005; to 2030, will 40 times. Developing countries have a high degree of solar energy concerns, the Chinese renewable energy by 2020 will account for 12.5% of the total electricity supply; in India by 2012 the share of renewable energy will reach 12%.

Need support to improve efficiency power inverter

The rise of emerging markets, often means the birth of new opportunities. As a new solar energy, battery manufacturing, power conversion and other related companies to play a new stage. Commenting on the new energy future prospects, International Rectifier (IR), vice president of strategic market development AlbertoGuerra said: "For home and business environment, the future of the energy saving strategy is to use the smart grid and smart appliances, and increased use of solar energy ( and wind) technology to generate electricity. "

Because PV systems produce DC current, but mainly for civilian power to AC power, and solar power will eventually run into the grid, which means that solar power inverter must be converted to alternating current to direct current drive home electrical appliances load. Therefore, the inverter in the solar power generation system has a pivotal role.

Inverter power supply main function is to enter into a variable DC voltage AC sine wave output without interference, both for equipment use, but also feedback to the grid. In addition to achieving AC-DC conversion, the inverter can also perform other functions, such as the circuit is disconnected, to prevent circuit damage due to current surges, also can charge the battery, on the use and performance of data storage, and maximum power point tracking (MPPT), to maximize the efficiency of power generation.

"Improving the energy efficiency of high-power solar systems, inverter is an important part, it is to ensure that solar energy conversion efficiency and return on investment the key factor." Infineon Technologies (China) Co., Ltd. home appliances and industrial power device market manager for Chen Ziying special emphasis on improving solar power generation system is the inverter elements.

Although the solar cell manufacturers in recent years has been committed to improving the photoelectric conversion efficiency of solar cells, but in February 2010 on the highest solar cell conversion efficiency of view, 15cm × 15cm 200μm thick solar cells can only achieve 19.3% conversion efficiency. As the photoelectric conversion efficiency of solar panels is relatively low (average about 15%), so get as much as possible from the solar panel output power inverter responsibility fell on him.

"National Semiconductor Asia Pacific Business Development Director Zhang Yaojiang core markets that the solar system's biggest challenge is to optimize inverter performance."

Photovoltaic technology policy remains uncertain technological breakthroughs

Photovoltaic technology policy remains uncertain technological breakthroughs

PV industry a much-anticipated introduction of a fixed electricity price delay, and photovoltaic power station in the new round of tendering declaration programs fail. The current pace of progress in photovoltaic technology decision-makers clearly did not meet expectations, introduction of more robust policies also need to have a more clear industry breakthrough, and power generation costs.

Indeed, the cost of solar power project in last year's tender show in Dunhuang amazing "one drop" from the past up to 4 yuan per kWh electricity price of around about 0.69 yuan to a minimum offer / degree, in price 1.09 yuan / kwh. 13 PV companies in the industry even claim that in 2012, PV 1 yuan per unit of electricity price target.

However, a dramatic decline in cost of power generation is not entirely due to technological progress, but more importantly because of polysilicon raw materials prices collapse. Polysilicon market in 2008 experienced industry-wide downturn, most businesses were shuffling out, polysilicon prices decline, making over 40% of the total cost of photovoltaic cells to lower component prices.

Apart from photovoltaic cell components, including the cost of PV power inverter, power transmission and distribution systems, solar bracket, power station construction and land cost of installation, including inverters and other hardware devices dominates the total cost of weight. And because high-tech inverter products do not scale in domestic production, the price has been high.

It is precisely because the past two years have seen rapid development of photovoltaic industry in the process of various non-normal factors, support PV industry started to slow down the rhythm. Why has not issued the relevant departments for industry looking for a fixed electricity price, people close to the National Energy Board that the current policy-making departments also do not see the PV industry has a major technological breakthrough. Photovoltaic conversion rate on the current terms, although laboratory has reached 25% conversion rate or even higher, however, after the industrialization of how much can be achieved in the end, the cost can reduce the number, now is not clear.

2009 China PV industry was considered to start the "Year One." Last year in March, the Ministry of Finance, Ministry of Housing and Urban launched the "Solar Roofs Initiative"; the same year in July, the Ministry of Finance, Ministry of Science, National Energy Board jointly issued a "demonstration project on the implementation of the Golden Sun's notice." The introduction of these two policies was once inspired to make photovoltaic industry, long-term "two out" of the PV companies seem to see the huge domestic market, good start.

However, after a period of policy implementation, industry enterprises found that the two policies is not enough subsidies and support to boost domestic demand, experts and businesses began to urge implementation of the "Tariff Act," a fixed electricity price in the form of support PV industry.

Photovoltaic electricity industry has been that the Internet is an ideal fixed support policies, to give investors a fixed, clear return on investment expectations, establish clear long-term planning, reduce the price by successive way to motivate technical progress. To model the form of the current domestic and network operation of photovoltaic power plants, electricity price entirely by the local government according to the particularity of each demonstration project may be, there is no single standard.

In fact, policy makers, the minimum investment in leveraging industry is the largest of its policy of pursuing the best results. With photovoltaic technology breakthrough advances have been significantly lower the cost of the path is becoming clear, the PV industry is expected to support the plan timely icing on the cake.

PV Enterprise has now increased the efficiency of energy conversion and reduce the cost of photovoltaic power generation to seek new technology path, while constantly improving existing photovoltaic conversion efficiency, on the other hand, some companies and research institutes is studying the solar light, heat utilization. Empirical data shows that solar energy if the shine is 100%, 10% of the panels will be reflected away, assuming the conversion efficiency of solar PV 20%, then there will be 70% of the solar energy into heat, and this heat to use potential for very large, but also reduce the cost of electricity will become an important way.

Environmental pollution and energy shortages forced the countries to actively search for alternative clean energy, photovoltaic power generation using solar generated current, not only endless, clean sound, is the best alternative energy sources. Initially limited by high cost of power generation to rely on policy support and develop the market, but in the long run, decrease the cost of photovoltaic power generation will remain at a reasonable level return on investment, market demand for PV can be long-term maintenance of high growth.

Current PV cost is still much higher than conventional power generation costs, but the countries of the falling cost of photovoltaic power generation rate to maintain a positive optimistic attitude. Germany, in 2007 the forecast decline in the cost of PV power generation that, in 2017 about the cost of photovoltaic power generation and conventional power generation costs will intersect at 27 ~ 28ct/kWh, then the cost of photovoltaic power generation will continue to reduce, but the cost of conventional power generation is higher and higher, the competitive advantage of PV will be fully demonstrated. The United States issued in 2006, the cost of the photovoltaic power generation forecast is more optimistic, they believe the cost of photovoltaic power generation in 2015 intersects with the cost of conventional power generation, about 10 to 15 cents / kWh or so.

Photovoltaic power generation is the most promising environmentally-friendly energy, great space for future development, we are still optimistic about long-term development of the industry. With a complete vertically integrated PV industry chain enterprises is undoubtedly the most competitive, since they can lower the maximum cost of the highest profit margins. Hai Tong Group is currently working with 100 million asset replacement optical crystal, is expected to complete the restructuring this year in June. 100 million is the country's eighth-largest crystal optical components manufacturer, is the only one with a complete A shares photovoltaic industry chain enterprises, the current capacity of 200MW, in building capacity of 150MW, by the end of June this year, new capacity can be fully put into operation at full capacity If production capacity up to 400MW. First half of the company has booked orders, product gross margin by nearly 40% to a record high.

As the instability of solar energy and photovoltaic industry network has been troubled by the biggest problem. UPS uninterruptible power supply through to solve this problem is undoubtedly a good idea to find alternative.

Get in line with European standards, Huntkey got Norway NEMKO certificate

2010-05-21T15:55:00.002+08:00

Get in line with European standards, Huntkey got Norway NEMKO certificate

Filed NEMKO, many people may feel strange. Indeed, the power in the consumer products area, NEMKO far 80PLUS be accepted by the people but as a very old world, qualified mechanical and electrical products certification body, NEMKO involved, including low-voltage signal, electromagnetic interference, mechanical tie, medical equipment, explosion-proof equipment, telecommunications, signal , car signal, building materials and many other fields.

From 1933 to today, NEMKO has gone through 77 years, from the home of Oslo, and slowly walked Germany, Italy, the United States, Canada, UK, Spain, Finland, Sweden, Japan, Korea, China Taiwan, Hong Kong and the China.

Since NEMKO 1998 entered the Chinese mainland has been quick in four major cities (Shanghai, Beijing, Shenzhen, Guangzhou) to establish a service to provide professional and competitive consulting, testing and certification services. Services include: Electrical Safety Services (LVD), Electromagnetic compatibility (EMC), ergonomics, chemical analysis (RoHS), energy-saving environmental protection (Eup, REACH) and the whole process of product performance and production support. Consultants and certification of products ranging from home appliances, lighting, information equipment, office equipment, electric tools, audio / video equipment and other electrical equipment.

On 2010 April 23, the world's sixth largest power plant, China's leading power supply manufacturers Hnutkey own lab power supply through the performance of ERP NEMKO laboratory tests, and this is from the U.S. Energy Star Huntkey Laboratory (Energy Star) and the CEC (California Energy Commission) efficiency after the third class license testing.

Huntkey years has been concentrated in the European market, business, finally some improvement in recent years, often to our readers will electromechanical channel read some time ago "safe overclocking 732W Huntkey 80Plus550W comprehensive test", which shall be Huntkey testing market in Europe Sales of the high-end products. Since April 26, 2010, all is not certified through the ERP standard power adapter does not allow sales in the EU, Huntkey win this certification, fully proved Huntkey want to go out into the world's determination.

Hunykey certification through the ERP, the ERP certification on their own products no longer need to commission a third-party certification through ERP laboratories to speed up the internationalization of product rate, effectively shortening the product from design to mass production and finally listing time.

In my opinion, Huntkey through ERP certification further demonstrates Huntkey power adapter as the world's sixth largest manufacturer of technical strength, but also indirectly proves this is not just rely on China's sixth largest population base was a huge success. Let us wish Huntkey to cast off the burden of past achievements and efforts of China's power industry will be brought to the forefront of the world.

Research status of permanent magnet synchronous motor

2010-05-21T15:54:00.002+08:00

Research status of permanent magnet synchronous motor

Early research on permanent magnet synchronous motor mainly fixed-frequency power supply operating characteristics of permanent magnet synchronous motor research, especially in steady-state characteristics and performance of the direct start. Permanent magnet synchronous motor is starting to rely on the direct provision of damping winding asynchronous motor torque to accelerate to near synchronous speed, and then by the reluctance torque and synchronous torque will pull into the synchronous motor. VBHonsinger and MARahman and others have done a lot in this area of research.

Foreign eighties of last century began inverter permanent magnet synchronous motor in-depth study. Power inverter permanent magnet synchronous motor with permanent magnet synchronous motor for starting the same structure, but in most cases, no damper winding. Damper winding has the following drawbacks: First, the damper winding heat, the permanent magnet material temperature rise; second, larger moment of inertia damper windings, the motor torque inertia ratio decreased; Third, the alveolar damper winding torque of the motor pulse increased. In the inverter case, the original characteristics of permanent magnet synchronous motor would be affected, the steady-state characteristics and transient characteristics and a constant frequency of permanent magnet synchronous motors have different characteristics compared. After 1980, a large number of papers published research permanent magnet synchronous motor mathematical model, steady-state characteristics, dynamic characteristics. AVGumaste other of voltage inverter, steady-state characteristics of permanent magnet synchronous motor and the current inverter, steady state characteristics of permanent magnet synchronous motor.

With the permanent magnet synchronous motor control system performance requirements of the continuous improvement of the need to design a high efficiency, high torque inertia ratio, high energy density permanent magnet synchronous motor, GRSlemon speed control system and others for fast dynamic performance and high efficiency requirements, proposed the modern design of permanent magnet synchronous motor.

With the micro-computer technology, permanent magnet synchronous motor vector control system of full digital control has achieved great development. D. Naunin so developed a permanent magnet synchronous motor vector control system, using 16 single chip 8097 as a control computer, to achieve a high precision and high dynamic response of the full digital control. The late eighties, early nineties has published extensively on such BKBose Permanent Magnet Synchronous Motor Vector Control System Digital Control of paper.

Permanent magnet synchronous motor vector control system using PI speed controller is mostly (PI) control. PI controller has simple structure, good performance of the control object parameters are not sensitive to the advantages. 1991, RBSepe for the first time in the speed controller with self-tuning control. Early adaptive control systems are mainly used in DC motor speed. National Taiwan University Images From the first time, robust control theory such as permanent magnet synchronous motor servo drive. Motor during operation, the model and the parameters are changing, changing the model parameters and control system performance will lead to the decrease. Modern control theory in a variety of robust control techniques to the control system parameters in the model and to maintain good performance. Therefore, various robust control techniques used in the field of motor speed, can greatly improve the speed performance of the system. In this regard, the use of the more successful control techniques are: adaptive control, variable structure control, parameter identification techniques.

Adaptive control techniques to improve control of objects and changes in operating conditions when the control system performance, N. Matsui, JHLang and others will be adaptive control technology for permanent magnet synchronous motor drive system. Simulation and experimental results show that the adaptive control technology enables speed control system in the motor parameters change to maintain good performance. Sliding mode control due to its special "switch" control mode and the motor speed control system inverter "switch" model similar to the robust control and has good features, so in the field of motor control has broad application prospects .

Motor parameter changes on-line identification, and identification of the parameters used to control speed control system, but also to improve the control system robustness. With the development of artificial intelligence, intelligent control has become a modern control an important branch of the field, electric drive control system of intelligent control technology has become a major electrical transmission control direction, and electric drive technology will bring new era. At present, an effective way to achieve intelligent control has three: expert system based on artificial intelligence (ExpertSystem); based on fuzzy set theory (FuzzyLogic) fuzzy control; based on artificial neural network (Artificia1NeuralNetwork) neural control. BKBose and others from the late eighties has been working in the field of artificial intelligence applications in electric transmission and achieved gratifying results of research.

The Smart Grid is facing two major challenges

Abstract: According to the Embedded Systems Conference (ESC) in a group of experts to say, smart grid is facing many challenges, including ensuring the safety of communications equipment to the understanding of consumer behavior.

According to Embedded Systems Conference (ESC) in a group of experts to say, smart grid is facing many challenges, including ensuring the security of communications equipment to the understanding of consumer behavior.

"There are many issues to be resolved." United States National Institute of Standards and Technology (NIST)-led National Coordinator smart grid standards GeorgeArnold said.

"There is one area where we really need to do more work, that is dealing with electromagnetic related problems. For example, the so-called suitcase bomb (suitcasenuclearbombs) or solar storms (solarstorms)" Arnold said. "The military's system of dealing with electromagnetic pulse, but not practical, so we need better physical and electrical design to address these impacts." He added.

Arnold and other engineers are very confident of the importance of ensuring the future of digital, network-based grid security.

The security of smart grid

"We have the best talent in the world to realize how to protect the power grid," Arnold said, "I think the problem is not design products, but the use of practice, this is where the difference."

To ensure the safety of intelligent design has become the new mantra network engineers, ChrisKnudsen said that he was responsible for PG & E smart grid standards and architectures, "I am very confident that we have adopted a best practice approach, we have done our best." Knudsen said .

We have a laboratory, including a complete substation and a substation outside the corporate firewall, Knudsen said: "We will here the results tested for the experimental device, so as time goes on, services scope, we will have more confidence in the future. "

Smart grid will also promote a series of new generation communication systems, these new communications system will not only security but also can be suitable for harsh conditions and has a longer service life. Cisco Systems Intelligent Network Department of New Business Development Manager, said Michael Fuller MichaelFuller said: "If I want an electric pole on the deployment of a router, required to pay a high cost can be achieved, it must be reliable."

As standard, NIST released late last year, the framework of a smart grid, but "it is more of an artist's first draft and sketches - of course, is the high standard of water." Arnold said.

For example, "a lot of work in the industry, such as renewable energy sources such as solar photovoltaic DC and turn it into AC power for the power inverter interface between the richer", Knudsen said.

At the same time, a charge for connecting consumer electronics devices to energy-saving standards for power line home network committee is making headway. Is expected to open in May's meeting, the details of its latest standards, Arnold said.

Not yet clear consumer demand

"Consumers are God," advocating a broad coalition of smart grid - GridWise Union President KatherineHamilton said, "We need a better effort to figure out how the actions of consumers," she said, and pointed out that the establishment of a market research group .

"We also need to figure out how to calculate the investment over time, benefit, this bit difficult because we do not know how consumers interact with the grid." Hamilton said.

Economic benefits exceed the cost of the facility to deploy the new system the cost to get approval, PG & E's Knudsen said, "Before we introduced these devices, most of the problems we do not understand that we need to learn a lot." He concluded.

The fourth SNEC International Solar Energy Exhibition has been brilliant over on May 12,

Massive fourth SNEC (2010) International Solar PV Exhibition has been extended two days, three days will be May 12 drawn to a successful conclusion; with world-class academic standards of today's fourth SNEC (2010) International Solar PV Assembly also will be held today in Lujiazui, Shanghai International Convention Center was opened the curtain.

1 users in the last year, "Fu-step Business Forum" on-line message praised the Third SNEC Shanghai Photovoltaic Exhibition: "Exhibitors must participate in this exhibition." The show substantial progress than last year. Pavilion broader, more exhibitors, exhibits updated way more alive, two days to tens of thousands each day in 85 000 Hall, more than 1,400 booths in the endless stream, surging crowd, proved the success of this exhibition, also proved Organizers did not live up to their expectations of the community.

Many exhibitors at the show come up with their own unique skills excellent. Implementation of Shanghai Aerospace Electromechanical domestic zero breakthrough "plasma enhanced chemical vapor deposition", ABB Engineering Limited from Shanghai up "claw"? Get the battery slice? Into the basket, just 0.3 seconds of the ABB sorting robot, are widely recognized by the market and customers of Emerson's UnidriveSPV CT photovoltaic power inverter and many other high-tech, high efficiency, high precision products, especially favored by the visitors, while thousands of miles, from far away European shipped large machines Schmid, brought from the island nation of Japan AGC Asahi Glass Precision Technology, Taiwan and Taiwan come to the exhibition of the top technology companies such as crystal, also know what's the buyer found, or start talking about became bulk of the sale, to open this infinitely vast market of China created a solid premise.

Shanghai people on this exhibition to show enthusiasm, but also far beyond imagination. While the Expo has attracted many people, but this solar event has attracted a lot of "non-professionals." An ordinary secondary school, led by the President himself, with more than 10 high school students love solar PV exhibition tour together, no wonder the media to "PV Expo" the nickname for the current photovoltaic SNEC Shanghai International Exhibition.

Of course there are regrets. Application late last year which led to stand well, so grab the exhibition "First Business," the Japanese company Samsung DIAMOND, although the exhibition hall this year well, and larger, but the face of a large number of professional buyers, they are still obviously felt too small, trying not to open hands. There are also some exhibitors, because the machine is too large, and field machinery and equipment not kept pace, so more difficult to exhibit, also can become a variable time dismantling hall.

The excitement of non-professional, with very professional results, the fourth SNEC Shanghai International Photovoltaic Exhibition will in Shanghai, in China, even in the history of the world's solar PV industry, leaving a very handsomely.

Use micro-inverter to optimize solar system

2010-05-13T09:46:00.000+08:00

Use micro-inverter to optimize solar system

Solar system for optimizing the efficiency and reliability is concerned, a relatively new means of connecting to each solar panel with micro-inverter (micro-inverter). For each block, with a separate mini-solar panel power inverter allows the system to adapt to changing load and weather conditions, allowing for the single-block panels and provide the best conversion efficiency of the entire system.

Micro-inverter structure can simplify cabling, which means lower installation costs. By making consumers more efficient solar power system, the system "recall" the original use of solar energy technology will shorten the time required for investment.

Power inverter is the key to solar power generation system of electronic components. In commercial applications, these components are connected photovoltaic (PV) panels, storage batteries and local electric power distribution system or utility power grid. Figure 1 shows a typical solar inverter, it is the output from the PV array into low DC voltage battery DC voltage, AC line voltage and voltage distribution network several kinds of voltage.

In a typical solar energy collection system, a number of solar panels in parallel to an inverter, the inverter will come from the variable number of photovoltaic cells convert the DC output of clean sine wave inverters 50Hz or 60Hz.

In addition, it should be noted that in Figure 1, the microcontroller (MCU) module TMS320C2000 or MSP430 typically contain, such as pulse width modulation (PWM) module and A / D converter on-chip peripherals such key.

Traditional sensor technology development in the wind power industry

2010-05-12T17:42:00.002+08:00

Traditional sensor technology development in the wind power industry

From the early days of human development, they put to use wind as an energy source, with the scientific and technological development, people began to use wind power more accurately.

Germany, Schleswig - Holstein is located between the North Sea and Baltic Sea, not even in the case of wind, Rexroth company's wind turbines can still run. If the wind changes from northwest to north 8 degrees, wind measurements will be the sensor to the signal transmission to the control system, control cabin yaw drive to locate a suitable location. Wind measurements, including wind speed and wind direction sensor sensors, along with the development of wind power industry to develop. In general, the wind speed sensor should meet the measurement range of 0 to 60 m / s, the error range of 0.5 m / s within the working environment temperature should be to meet local air temperature. The wind sensor should meet the measurement range of 0 ~ 360 degrees, 2.5 degree accuracy within the working environment temperature should meet the local temperature conditions.

Institute of Electrical Engineering Chinese Academy of Sciences Research Associate Li Jianlin new energy group, said, "wind power industry on the measurement of high voltage, high current sensors, vibration sensors, temperature, humidity, wind, and pressure sensors will be to promote product applications." which, due to wind turbine current sensor is an essential component in the converter, the wind power industry is particularly important in the application. In some power inverter, the small and PCB installed with a current sensor is widely used. These sensors are part of the converter closed-loop control, ensuring rapid response inverter. When the inverter and the generator of intelligent power control also used, to ensure that wind turbines can start after the wind speed in a very wide range to provide continuous power for the grid until the wind turbines in the ceiling when the shutdown date. In order to drive the best location, each sensor within the converter will measure continuous current, the circuit control the quality and response time of the final design and by the current sensor to determine performance. This is a small current rating of the closed-loop current sensors are widely used in wind power industry reasons. In addition to excellent linearity and accuracy, the closed-loop current sensor itself has a high bandwidth and fast response time and so on.

Jian-Lin Li pointed out that the domestic market has yet to be current sensor development, especially high-current sensor technology, lags far behind international standards. As the domestic high-current sensor technology is relatively immature, the domestic wind power machine manufacturers in the procurement of high-current sensors, most will choose to import products, the prices of imported products is often higher than the price of domestic products, which to some extent, increase production cost pressures. In the small current sensor technology, the technological level of domestic and international level is not much difference.

As the domestic wind power stations are situated in the "Three North" (north, northeast, northwest), and coastal areas, climate is relatively poor, so the wind turbine high on the sensor performance requirements, especially for heating function, seismic resistance, high-frequency electromagnetic interference, anti-reverse polarity (connect) and wind direction indicators such as shock and vibration requirements of capacity is far higher than the universal sensor performance indicators, and tidal power station unit also requires sensors with good anti-corrosion water .

Li Jianlin, said sensor applications in the wind power industry is not limited to wind power industry, the electric power industry, the use of sensors is more occasions. In the power plant, power plant mainly uses pressure sensors, temperature sensors, flow sensors, mainly used in power transmission in the field voltage sensor, current sensor. Most of them are technological level but require a higher reliability and stability of common sensors, and require a higher technical level light sensor applications are also less in the power industry. As the power plant, power station sensor device manufacturers generally choose from the unit, so the relatively high internal sensors. Transmission field is different, the relative power in the field, put off because the sensor is relatively small, select brand each grid area is not very sensitive to price, and the use of some relatively new technology can improve the transmission and distribution, and so the foreign brands of sensors apply more.

LED backlight used in personal computers is increasing

LED backlight in the LCD panel used, in addition to TV panels, the panels in notebook PCs and LCD display panel has also been developed rapidly. The following will computer LCD panel LED backlight trends, on May 11 at the "Display Search LED Forum 2010" on the LED you analysts described the latest trends to be summarized.

In the large-screen LCD panel applications, the first to promote universal LED backlight panel that laptop. With the improvement of LED luminescence efficiency and low price of, in addition to the original with LED backlight type of high value-added mobile personal computers, the market in 2008 after a small laptop computer (screen size of less than 10.2 inches) in almost all models are equipped with LED backlight. Moreover, starting from the first half of 2009 for the screen size of 15.6 inch and 14-inch notebooks such as main products, this LED backlight equipped for a rapid advance. 2010 notebook computer (including a small laptop computer included) will total 200 million 14 million units, equivalent to 88% of estimated 100 million 88 million units will use LED backlight panels.

On the other hand, LCD display with LED in 2009, compared with the priority use of the reduction of CCFL (cold cathode) the number of panels. Therefore, 2010 will be a LED backlight panel began to spread year round. 2010 LCD monitor shipments is forecast to be 100 million 71 million units, equivalent to 15% of 26 million units expected to be using LED backlight panel.

Notebook panel LED backlight structure, under light guide plate (LGP: Light Guide Plate) shape can be divided into wedge-shaped (Wedge Type) and flat-shaped (Flat Type). As the literal meaning of the wedge using a wedge-shaped light guide. As part of the composition, shape and structural panels close to CCFL backlight panel, there is currently less expensive LED backlight is the main product. Compared to CCFL backlight panel of premium (higher rate) for 2 to 3 U.S. dollars. The flat plate-shaped light guide shape is to use the product. As the LED also uses thin materials, it can inhibit the overall thickness of the panel. Compared to CCFL backlight panel's premium of 5 ~ 10 dollars. With the future improvement of yield and low price-based, LGP is expected to gradually transition to the flat shape.

LED display panel backlight, from 18.5-inch low-cost model introduced. LED display panel backlight premium is 2 ~ 6 USD, but as way without CCFL backlight power inverter circuit used, it could eventually be offset. Moreover, the use of small-screen TV display panel to expand the impact of use of LED has been the model of small-screen picture began to use LED backlight. In addition, images, etc. in part of the business use, since the color is different from the performance and lifetime characteristics of CCFL panel, so stay with LED backlight panel TV manufacturers can be seen everywhere.

While the LED backlight supply is expanding rapidly, but appears a short time, and not as a device for use in design technology and experience accumulated. In the LED luminous efficiency and the basic properties of the growing improvement in the panel makers and TV manufacturers to further scope for additional value-added increasingly little.

Line double-conversion UPS

2010-05-12T10:16:00.000+08:00

Line double-conversion UPS

This is the power range of 10kVA power over the most common type of UPS. Shown in Figure 4-line double-conversion UPS, chart, in addition to the main power path is the inverter (not the AC main power), the other with the same back design.

In the double-conversion online design, the input AC power failure and will not activate the switch, because the input AC power has been a backup battery, backup battery to the output by the inverter. Therefore, the input AC power failure, no time-line running state conversion.

In this design, the battery charger and inverter to convert the entire load power, and generate more heat as a result of reduced efficiency.

This UPS provides ideal power output performance. The reliability of this design over other designs, but the continued depletion of lower power components such reliability, but also throughout the life cycle cost UPS, due to low power efficiency and energy consumption accounts for a large part. In addition, the large battery charger input power is usually obtained by nonlinear, may interfere with building power supply system or cause the failure of standby generators.

Delta Conversion On-line type UPS

Delta Conversion On-line type UPS design is a newer design, which is 10 years ago to introduce the technology, it overcomes the double-conversion online design shortcomings for 5kVA to 1.6MW power range of applications. And double-conversion online design similar, Delta conversion online type UPS is always provided by the power inverter load voltage. However, the additional Delta Converter also to the inverter output power. In the AC power failure or tampering of the case, this design behavior shown by double-conversion online design exactly the same.

Delta conversion topology to understand the energy efficiency of a simple method is to examine from the 4th floor of the building to the 5th floor of the energy required for transportation of parcels, as shown in Figure 6. Delta conversion technology through the delivery of parcels by distance is only the beginning and the end of the difference between the amount of (Delta), and thus saves the energy. -Line double-conversion UPS converts DC to AC power, and then from DC can be converted to AC; and Delta converter to move the power output from the input.

Delta Conversion On-line style in the design, Delta converter has a dual role. The first role is to control the input power characteristics. Sinusoidal input to obtain its power to minimize the clutter reflected to the device. This ensures that the generator system with high efficiency and compatibility, while reducing the heat distribution system and system losses.

Delta conversion-line double conversion UPS provides online design with exactly the same output characteristics. However, the input characteristics of the two designs are usually not the same. Delta conversion online design provides dynamic control, the input power factor correction, while the traditional solutions do not appear inefficient use of filter questions. The greatest advantage is greatly reduced energy losses. In addition, the input power control also allows UPS to all units compatible with, Delta conversion-line technology is the only patent-protected core UPS technology, a large number of UPS suppliers can not apply the technology.

In a stable state, as compared with the double-conversion design, Delta converter allows UPS to a much higher efficiency of the power to the load.

Online interactive UPS

2010-05-12T10:08:00.002+08:00

.Online interactive UPS

Online interactive UPS for small business, website, departmental server, the most common design. In this design, the battery to AC power converter (inverter) is always connected to the output of UPS. If the input AC power inverter normal reverse operation, it will recharge the battery.

Once the input power fails, the switch opens, and through the battery to the UPS output power. UPS topology with reserve-type compared, due to inverter output is always open and maintain a connection with, this design further enhance the filtering effect, and reduce the transient over-voltage conversion.

In addition, the online interactive design will usually include a transformer tap change. Thus, when the input voltage changes, by adjusting the transformer taps can better adjust the voltage. In the case of low voltage, voltage regulation is an important feature, or UPS will switch to the battery and ultimately could not supply. Because of this situation and frequent use of batteries may result in premature failure of the battery. However, you can also design follows inverter, that is when it fails, still allowing the flow of power from the AC input output, so that eliminated the possibility of single points of failure and effectively provides two independent power path. This UPS design of high efficiency, small size, low cost and high reliability, and to rectify the low or high voltage electricity, so in the 0.5-5kVA power range of application areas were predominant.

To know the merit and demerit of several types of UPS systems

At present, the market is flooded with different types of UPS systems, their characteristics are different. Now, APC UPS for each type are given a clear definition of the practical application of each system, and lists the advantages and disadvantages of various systems. With this information, you can make informed decisions, select the appropriate UPS topology of their needs, create efficient enterprises.

The understanding of UPS, it is also generally agreed that there are only two types, namely, back-up type UPS and Online UPS. The two commonly used terms and can not correctly describe the existing UPS system. In the correct understanding of the different types of UPS topology, you can eliminate many of the UPS system error view. UPS UPS topology refers to the basic characteristics of the design. Typically, models of different manufacturers in the design or topology very similar, but they differ in significant aspects of performance characteristics.

UPS type

There are many ways to design UPS systems, UPS designed with different performance characteristics are very different. The most common design as follows:

Reserve type

Online interactive

Backup type - FMR

Double-conversion-line

Delta Conversion On-line style

UPS back-up style

Reserve-type UPS for personal computers the most common type. Switch set to select the filtered AC input as the main power (solid line path), once the main power fails, it will switch to the battery / power inverter as the backup power supply. Once this occurs, the transfer switch must operate, the load switch to the battery / inverter backup power source (dashed path). Inverter only starts when a power failure, so called "back-up style." The main advantage of this design are high efficiency, small size and low cost. If the use of appropriate filter circuit and surge protection circuit, these systems can also provide appropriate noise filtering and surge suppression.

Global PV installed capacity is estimated to 13.6GW in 2010

2010-04-27T17:48:00.000+08:00

Global PV installed capacity is estimated to 13.6GW in 2010

Abstract: 2009 end of the world's photovoltaic (PV) market maintained the strong momentum into 2010, iSuppli Corporation to promote solar energy installed capacity forecast for this year significantly increased to 13.6GW.

The end of 2009 the global photovoltaic (PV) market to maintain the strong momentum into 2010, iSuppli Corporation to promote solar energy installed capacity forecast for this year significantly increased to 13.6GW.

iSuppli's previous forecast PV installed capacity in 2010 is 8.3GW. The new estimate is equivalent to growth of 92.9% compared with 2009. By 2011, global PV installed capacity will grow to about three times in 2009, up from 7.0GW to 20.3GW.

PV installed capacity this year, the market will ebb. First quarter of 2010, due to the adverse effects of the winter elements, capacity may be lower than the fourth quarter of 2009. However, the second quarter is expected to usher in the global photovoltaic industry will install the climax. Germany in July starting from the lower electricity price policy (FIT) rate, the consumer will drive change in the policy before the installation of photovoltaic systems. The third-quarter market correction will occur, but because other countries FIT in the January 2011 deadline, the fourth quarter is expected to installation activities will substantially increase.

The second half of the main factors driving the market, home owners and project developers will continue to enjoy favorable return on investment (ROI). ROI in the second half of 2010 will reflect the FIT system can compensate for lower prices. In some cases, ROI will remain at 10%. 2009 solar module prices down, are just now being reflected in the price system to promote the system and lower prices.

Clearly, the quarter of the market volatility, will PV supply chain and production planners to create difficulties, difficult to determine the needs of their size, location and timing of demand for the demand.

Possible shortage?

With the PV installed capacity in 2010 raised its forecast for 13.6GW, may experience material supply constraints this year. Power inverter module may also spot shortages, may suppress the market growth rate.

May not be enough because the installation of officers trained to meet the large number of installation needs. Install the bandwidth problem may also occur.

Outlook 2011, or may experience more supply constraints. According to iSuppli, the enterprise capacity of notice, unless the additional expansion of production capacity, or crystalline silicon modules may be in short supply in 2011. iSuppli believes, crystalline silicon modules in 2010 the plant capacity utilization will rise to 90%. In addition, many front-line of crystalline silicon modules and the battery supplier's products will be out of stock. The second and third tier module supplier's current business is also growing in Germany, struggling to supply its required modules.

Solar panels are unsafe

2010-04-16T17:40:00.002+08:00

Solar panels are unsafe

Last week, a San Diego solar panels on the building led to a fire, the fire exposed the California building codes in many cities there is a potential fire deficiencies. Prior to California to encourage solar power system installed on the roof, tens of thousands of homeowners responded to this call.

Experts said that in most cities, the government does not force homeowners to install solar panel switches, which switches off in case of emergency current from solar panels. The event of fire, as long as a sunny day, a dangerous current will keep flowing along the wire, have no way of firefighters.

Last Wednesday, when, AmyPavis experience in their own homes caused by a solar panel electrical fire, she will never forget that feeling.

While many families spent fire extinguishers, San Diego fire rescue department has done a great effort, AmyPavis home solar panels on the roof is still burning several hours, until the last cut off electrical solar panels together with wire, the fire was finally extinguished.

Has investigated electrical fires for 25 years, said Snyder, like a fire caused by the solar panels, he had seen 50 cases, 5 of which suffered heavy losses since.

Snyder said the fire exposed the construction of a solar panel next obvious design flaws, particularly for broad use of residential solar battery panel users, is a very serious fire hazards.

In order to reduce carbon emissions and respond to rising electricity prices, the Government implemented the use of solar power generation systems, while in California Island, more and more heads of households installing solar panels. In July 2008 to June 2009, San Diego County issued a total of 432 permits to install solar panels, and in the next 9 months has increased to 760 permits.

Almost all of these devices include two switches, both switches are close to or directly installed in the power inverter.

A switch to minimize the AC into the room, and the other switch is protective, to prevent DC current leakage from the solar panel. Pavis home fires, solar panel DC switch power inverter in an old box, which increased the difficulty for the fire fighting. But Snyder that, even with the two switches are not enough to stop the fire.

He believes that there should be when the roof cut off DC power, the switch should be as close as possible solar panels.

"When the home circuit breaker is broken, this switch should be able to cut off the rectification power system." He said.

San Diego County, California building codes in accordance with custom, in the specification, not a mandatory installation of such a switch. Snyder said that in the region, only the Temecula are mandatory.

Temecula, California Forestry and Fire Department battalion chief, said the Director of CharlieDeHart, such high specification standards should be adopted, the firemen fighting the fire when solar panels can be quickly and effectively cut off the current, rapidly extinguish fire.

Some industry experts said that this is indeed a problem.

Executive Director of the California Solar Energy Industries Association SueKateley said DC line does fire threat exists.

As long as the sun, solar panels on full power, even on a cloudy day or night, it still maintains the power.

SueKateley said the fire caused by solar panels give us the real lesson is that homeowners should do regular checks on the solar power system to ensure that no problems and fire hazards. But she acknowledged that solar panels are to be developed to improve the safety factor.

The best develping way of power inverter is to ensure its reliability

2010-04-15T17:51:00.000+08:00

The best develping way of power inverter is to ensure its reliability

Inverter efficiency highlights the increasingly competitive market

With the solar energy industry in recent years, the rapid development of solar cell manufacturers have been committed to improving the photoelectric conversion efficiency of solar cells, from February 2010 the highest solar cell conversion efficiency of view, 15cm × 15cm thick solar cells only 200μm to achieve 19.3% conversion efficiency. As the photoelectric conversion efficiency of solar panels is relatively low (average about 15%), so get as much as possible from the solar panel output power from the battery falls the important task of the inverter body.

When the polysilicon, a component manufacturer for the meager profits of the golf battered the occasion, photovoltaic inverter manufacturers benefited from the terminal market of large-scale installation, gradually enter the high profit growth period.

On the inverter market competition, TDIPOWER Marketing Manager Greater China, said Li Xiaomin, "There are already areas of photovoltaic inverter manufacturers of many more mature, market competition becomes more fierce"

The next two years, photovoltaic inverter stage of the industry remains highly profitable, as more and more competitors enter, although the margin has been reduced, thanks to the increase in the total end-system installation, inverter industry is still maintained a high growth trend.

Do not blindly follow the trend of more potential fields in the high-end

PV inverter PV system as the core power control devices, with high technological content, the proportion of system costs account for between 10-15%. With the solar industry, concerned about the inverter manufacturers and users more and more.

As a professional power supply companies, TDIPOWER

After several years of development, product applications from the initial U.S. military extended to more sectors. Inverter is our part of many power products, mainly covering military, IT, industrial, medical and other civilian areas.

For the PV inverter, the Li Xiaomin said, because many are already in the field more mature producers, although we do not focus on the development of the area. Requirements in this area but the field of high-end and customer interest.

We present a variety of ways and strong solar system solutions providers for cooperation in restructuring the existing standard, or custom make to meet the application requirements of PV systems. In view of our customers before a large number of optimization programs, the experience, innovation and product to our customers to provide more room for development.

Reliability assurance requirements for diversification

As the main function of the inverter is a variable DC voltage input power into AC sine wave output without interference, both for equipment use, but also feedback to the grid. In addition to AC-DC inverter to achieve the conversion, should also be able to perform other functions, such as the circuit disconnect the battery, use and performance data is stored, and the maximum power point tracking (MPPT) and so on. Faced with these requirements, and use needs different time to meet the diverse product requirements and improve product reliability is particularly important.

TDIPOWER from its inception in close cooperation with the United States military has made a number of military power involved in design and production specifications. So far, even civilian products, but also still used in many military power supply design and production standards. Such as reducing the amount of design, 100% HASS testing, etc., to maximize the protection of product reliability.

Take Liezi, for there is no AC in the remote or underdeveloped areas, such as communications base stations on the plateau of Africa, we provide complete outdoor cabinet inverter system, the system to achieve IP66 protection rating, and other devices equipped with lightning protection is our company according to the local inverter design standards requirements, fully meet the demand.

The funds of photovoltaic research went into the plight –must develop its own core technologies

Recently a happy event for Nankai University Dr. Xu Shengzhi very happy after a very long period of operation, the school finally agreed that they moved to Bo Ling floor lab, his "Chinese Sankei Shimbun," told reporters: "The environment there area should be much better to address the crowded conditions in our laboratory. "

Nankai Optical Institute, take a number of 973 missions, accumulating some basic equipment, laboratory conditions are improving. Even so, compared with foreign laboratories is very backward. "The stability of equipment, poor reproducibility, leading to a large waste of resources. Test instruments even more difficult to meet the demand, however, improved test equipment requires a lot of capital investment."

"From the 'June 5' during the start, Nankai University, sustained over a long, very difficult. However, we should see how many brothers and units change due to lack of funds to support research, but also a lot to see." Nankai University, the experimenters photoelectric said not without bitterness.

From the "Plan" to the "Eleventh Five-Year", and explore large-scale study of sustainable energy development path is still the key. Including the use of light. PV systems, in terms of design and installation of related components or systems perspective, our country is rapidly developing. But there are still some issues to resolve, such as large capacity power inverter, and net metering and so on.

Nankai University, an experiment by the optical division of the "China Sankei Shimbun," told reporters: "At present the domestic photovoltaic research, our weakness is in basic research, said immediately, the solar cell production and the largest semiconductor chip production difference is much lower technical requirements, but to improve the conversion efficiency of solar cells needed to conduct joint research from multiple disciplines. "

Photovoltaic research experts recommend: "The current rise of photovoltaic market, many funds flow in.. Of course there will be some flow of research institutions, this is a good thing for the Institute. Should develop our own core technologies to enhance the photovoltaic the level of industrial technology, not again repeat the TFT (Thin Film Transistor) industry, the old road. "

The proposal of promoting solar energy development scientificly

2010-04-12T15:41:00.000+08:00

The proposal of promoting solar energy development scientificly
Question:

Global warming, Copenhagen, low-carbon economy, green Beijing Action Plan and a series of hot topics, so as a new energy (renewable energy) of solar energy development and utilization of more and more attention. Response to global climate change, our Government's commitment to new energy sources by 2020 (non-fossil energy) the proportion of total primary energy consumption up to 15%. Beijing Municipal Government issued the "Beijing speed up the development and utilization of solar energy, the development of guidance for industry" (hereinafter referred to as "Opinions"), six "Golden Sun" project in January 1, 2010 start.

Bright solar thermal conversion, photovoltaic conversion are two ways to be a clear understanding of science to their production, use, there are still the following problems:

1, the production process of high energy consumption: from industrial grade silicon to solar cell production process consumes 2.2 million watts / MW, is twice or more foreign countries. Glass vacuum tube solar collectors, only the drawn glass is energy-intensive process.

2, high pollution: polysilicon in the manufacturing process of silicon tetrachloride produced is a highly toxic pollutants, photovoltaic power generation system battery life of 5 years, handled properly will have a large number of waste batteries, the formation of new pollution sources.

3, the lack of capacity for independent innovation: key technologies and photovoltaic devices rely on the import of foreign, photovoltaic power generation system, controller, power inverter, battery and so there is a gap.

4, insufficient domestic demand, excess capacity: in 2008, polysilicon production capacity 20,000 tons, output of 4,000 tons, 80,000 tons under construction, hundreds of companies, investment 100 billion, more than the domestic market capacity in recent times. 2008 production of 2000 megawatts of photovoltaic cells, first in the world, representing the world's 1 / 3, but 90% to 98% for export, the actual formation of the large volumes of scarce energy resources.

5, the lower the market share of solar water heaters in Beijing: Beijing accounts for less than 2% market share, far below the Jiangsu and Zhejiang, Shandong, Yunnan and Hebei provinces. The reasons are: 1) Beijing conventional lower energy prices, energy supply is sufficient; 2) Beijing-based urban high-rise buildings, building density, impact of solar energy installation inconvenience; 3) the promotion of policy lag, many communities prohibit solar installation.

6, Beijing enterprises are less competitive industries: Beijing as the higher production costs, and Zhejiang and other southern enterprises, the industry less competitive, slower growth rate in recent years. Production costs due to Beijing Gao land prices, high labor costs, 企业 standardized operation, taxation heavier, in addition to the local market due to the slow, large enterprises Zhuyaoshichang Zai other provinces, Xiao Shou higher cost.

Analysis:

1, scientific understanding, use of green, the production must be green. Solar energy as renewable energy, its use is green, but the current production of high energy consumption, high pollution must attach great importance to increase research efforts to achieve green production. 2, the new highlight solar energy. Beijing has rich solar energy resources, solar resources in the region of the country in the world in the area between two categories, the annual sunshine hours to 2600-3000 hours, the cumulative amount of solar radiation to 5000-6000 MJ / m, with use of solar energy is extremely favorable natural conditions, and lack of wind resources, only some parts of Yanqing Guanting other relatively well and should therefore focus on increasing the proportion of solar energy utilization.

3, Beijing, research institutions and enterprises have strong technical strength. Beijing has many strong research and development capabilities of scientific research units and institutions of higher learning, such as: Beijing Solar Energy Research Institute, Tsinghua University, Beijing Polytechnic University, focused on a number of fields in the solar technology professionals with extensive experience, over the years use of solar energy and solar have made a large number of scientific and technological achievements, some of which scientific and technological achievements have reached the international advanced level, the core areas of domestic solar energy technology and advanced technology have come from basic research institutions in Beijing and related businesses. In the current solar thermal power, solar industrial applications, solar heating and other fields, enterprises have core technology, the leading domestic level.

4, development of the domestic market. Only increase the promotion of the use of green solar energy can be truly effective, our water heater products in 2007 accounted for 80% of the world, in mid-2008 production increased 31 million square meters, up 32.5%, with annual sales of 40 billion yuan, only Haier 1 / 3 volume of 125 million square meters of total reserves. Beijing has a large solar water heater industry, business size, annual output accounting for 4% of total production, higher than the production of large, Jiangsu, Zhejiang, Hebei, Guangdong, Yunnan and other areas, such as Beijing Samp have, Tsinghua sunshine, days General and other national leading enterprises, in technical strength, product quality, customer goodwill among the forefront of the industry.

Recommendation:

1, mainly solar thermal, photovoltaic supplement. In view of solar thermal technology is relatively mature, and with the people's living standards improve, Metro construction of new countryside construction and housing improvement in the proportion of water in the energy consumption increased, so Beijing's use of solar thermal utilization should be based, photovoltaic use supplement.

2, increase scientific and technological research, increase efficiency, reduce costs, green production, system development, and enhance competitiveness. Advantages of capital, talent and give full play to support the national engineering technology centers, research institutions, the establishment of high-level components of solar material, product testing laboratory, establishment of shared research platform to conduct generic technology research. Promote a combination of research, to encourage technological development, promoting technological progress around the key technologies used solar energy, green manufacturing processes, systems integration technology to increase science and technology research, improve efficiency, reduce costs and realize the industrialization of key technologies Beijing enterprises, high-end manufacturing, making Beijing a solar energy technology, standards, R & D center.

3, strengthen the norms, to ensure safe use. In the solar energy utilization, solar energy facilities and construction of Jie He often promote the use of a restricted part, should strengthen the building Li Yong Tai Yangneng research, proposed research and the construction Sheji sector should enhance cooperative, its inclusion architectural design specifications, to ensure that the legal construction using solar energy , security, application and beautiful. Part in the planning and approval phase, the realization of the conditions of solar synchronous designs, synchronous installation, promote the application of the scale. 4, development of farmer subsidy policies, market regulation of production. In the "views" on the new limit of two rooms, common commercial, industrial enterprises in public buildings and installation of solar water heating systems, and provides that "subsidies for single item scale of collector area to more than 100 square meters", while a large number of The average household water heater 2 square meters. Recommendations from the Waste Management perspective, learn the practice of home appliances to the countryside and other experience, study and formulate subsidy policy to encourage the direct use of solar water heaters, also set up access to limit the three small plants without disrupting the market at low prices. Through the user's choice, market mechanisms, promotion of enterprises to adjust production integration, technology upgrade, lower costs, survival of the fittest, to ensure long-term benefits of solar customers and market healthy development.

Solar market is prosperous and the price of inverter is expected to be lower

2010-04-08T17:41:00.000+08:00

Solar market is prosperous and the price of inverter is expected to be lower

The rise of emerging markets, often means the birth of new opportunities. As a new solar energy, battery manufacturing, power conversion and other related companies to play a new stage. Because PV systems produce DC current, but mainly for civilian power to AC power, and solar power will eventually run into the grid, which means that solar power inverter must be converted to alternating current to direct current drive home electrical appliances load. Therefore, the inverter in the solar power generation system has a pivotal role.

Inverter power supply main function is to enter into a variable DC voltage AC sine wave output without interference, both for equipment use, but also feedback to the grid. In addition to achieving AC-DC conversion, the inverter can also perform other functions, such as the circuit is disconnected, to prevent circuit damage due to current surges, also can charge the battery, on the use and performance of data storage, and maximum power point tracking (MPPT), to maximize the efficiency of power generation.

Although the solar cell manufacturers in recent years has been committed to improving the photoelectric conversion efficiency of solar cells, but in February 2010 on the highest solar cell conversion efficiency of view, 15cm × 15cm 200μm thick solar cells can only achieve 19.3% conversion efficiency. As the solar panel conversion efficiency is relatively low (average about 15%), so get as much as possible from the solar panel output power of responsibility falls on the inverter body.

Solar inverter performance improvement is more dependent on the power switching devices, like access to high AC output voltage and current, power devices require correct choice. China is the major development is the high-power solar systems, Golden Sun demonstration project provides financial subsidies for Interim Measures, a single project installed capacity of not less than 300kWp. With the increase of single-power, solar inverter technology and devices subject to restrictions on the form of relatively simple circuit, primarily three-phase inverter bridge, the important task of improving energy efficiency fell on power devices, the device itself, the performance and designed to use is the key.

In the small and medium-power solar inverters, many companies have their own proprietary circuit structure, a new generation of power devices so that these circuits even more powerful, efficiency, reliability, performance and other areas has greatly increased. Infineon has developed a series of solar application products, such as high-power three-level module Easy and Econo4 portfolio, 50A ~ 300A650V; high-speed IGBT and SiC diode PrimePACK module specification 600A1200V. These power devices will help to promote more than 100KW solar inverter efficiency to a higher level. In addition, Infineon's structure grooved-gate field termination technology FieldStopIGBT, CoolMOS, silicon carbide SiC diode in energy-efficient solar inverters have outstanding performance.

Pull out of the car inverter when car started

2010-04-07T14:05:00.003+08:00

Pull out of the car inverter when car started

When the car became an essential of modern life, in the car using a laptop, a cell phone charging more and more common, it is noteworthy that the use of these things in the car, not so arbitrary.

Di Xiansheng owners began a few years ago car inverter in the car and then the laptop at work. Not too long, the cigarette lighter and it broke. This seems very durable car inverter, is that so?

Good auto supply company Xian Hu told reporters that a few years ago because the smart car inverter security features may not perfect, so easy to burn cigarette lighter. Generally speaking, the car brand on the market today inverter, has the low-voltage, over voltage, over temperature, overload, short circuit protection and many other conditions, and built-in e-fuse, not because of prolonged use of equipment consumption best battery in the power, resulting in vehicles not start.

Hu said the purchase of car inverter, as we choose quality guaranteed authentic, in addition to the model should be noted that inverter power. Different models, power inverter, electrical can drive different. What is your electrical needs with inverter, the best time of purchase to the professional advice.

Inverter car owners to use the most common mistakes is that, to start the car, do not pull down the inverter. This is very easy to burn cigarette lighter. Regardless of any vehicle electrical, start the car must put inverter when the pull down, plug in the engine after ignition turn to avoid the impact of current instantaneous ignition and burning of electronic equipment is too large.

It is worth recalling that some owners of convenience, some of the DC DC appliances, such as notebook computers, mobile phones, PDA, etc. do not use their own in the car with the 220V power supply, and coupled with a simple converter plug directly used in the cigarette lighter This is very dangerous. Because the car battery voltage is unstable, direct access may be destroyed electrical appliances, electrical appliances will also greatly affect the life.

Chen Kai Xian Navigation Electronics Co., Ltd. Deputy General Manager also reminded the owners, the choice of car appliances, do not too much. Because the battery generally Jiajiao limiting current of 100 amperes, a new car battery voltage of 12 volts, used cars mostly 11-11.5 volts, car power supply load is limited, so car owners in the use of electronic devices, one can not mount too much. Too many devices attached, can also cause a mess inside line and affect driving safety. In addition, after flameout to remember off the device.

Increase the electronic equipments to change the original car lines easily lead to spontaneous combustion

2010-04-07T14:04:00.002+08:00

Increase the electronic equipments to change the original car lines easily lead to spontaneous combustion

As temperatures rise, to prevent spontaneous combustion car owner once again a topic of concern. Recently, Xi'an alterations caused by spontaneous combustion phenomenon of new cars to remind consumers to change the original car lines are dangerous!

Electronic equipment more convenient for vehicle owners to increase

Statistics show that an insurance company last June to September, on the spontaneous combustion kind of insurance claim 512, which modified cars for free to the vehicle ignition circuit caused the fire 60%. Although similar across the country have occurred because of alterations caused by spontaneous combustion cars, but there is still a lot of owners never bored.

Zhang just bought a Tiida, spent more than 3000 yuan to their own car video system installed a backup, he told reporters: "I am the person trouble, so when the election vehicle selected Automatic and installed a reverse image, and now much more convenient, as long as the gear hanging down, behind all see clearly what the situation. "

Cheng belongs to a family play, he almost had a number of commonly used electronic equipment to move the car, car refrigerator, car computer, stereo, etc. ranging. He told reporters: "While the power inverter once used to be burned, but I still feel so good when the car went out to play anything capable, more convenient ah!"

Easily lead to spontaneous combustion of improperly modified

National Motor Vehicle Products Quality Supervision and Inspection Centre car expert Tsang Chun school has modified the open vehicle, said vehicle ignition circuit fault is "the first killer", the proposed vehicle owners not to improperly modified.

Shaanxi Province in the Allianz Group Technical Director Zhao Jianli explained in an interview a change in the circuit can trigger spontaneous combustion of the reason, he said: "As a mandatory inspection, automotive factory will accept the strict fire-retardant function test, normally does not ignite. Automotive The circuit is strictly designed a certain load, if the owner is free to increase the electrical equipment, more than a circuit of the load, it is easy to burn out the fuse. If the arbitrary replacement of non-standard fuse, more likely to cause spontaneous combustion. Also, increase in electronic equipment, if some non-standard operations, such as directly from the cut line in the outlet head butt and not take insurance, then further increased the likelihood of spontaneous combustion. "

He reminded the owners said: "The majority of cars will be indicated in the manual, due to vehicle modifications which resulted in the loss of vehicles, manufacturers are not responsible. Therefore, modifications must be cautious."

Additional equipment is not in the scope of claims

Modification of vehicles because they cause losses, insurance companies will claim it?

Insurance industry Ho told reporters: "increase electronic equipment and increase the risk of conversion is equivalent to the probability of buying insurance if you have not been informed and increase the cost, the insurance company certainly does not claim to. If you buy insurance After the conversion, they should fulfill this obligation to inform the insurance agency and additional costs to do an endorsement. "

Meanwhile, Mr. He reminded the owners, many people consider themselves when buying a new car bought "All Risks" everything will be fine, in fact this is the wrong understanding, "many people have car damage, three responsibilities, robbery, a few scratches, etc. risk insurance as a whole, this is not true. Take spontaneous combustion for instance, the provisions of each company is different, some companies count spontaneous combustion within the Chesun Xian, some insurance companies will have a separate ignition. Owners must understand what they have bought the insurance, do not buy that 'all risks' to lose all security. "

Adapted best to choose a special piece to buy equipment

Although the changes of electronic equipment will increase the risk of spontaneous combustion, but they do give owners a great deal of convenience, how to compare the two to find the perfect compromise between the point?

Domestic electronic equipment, a large area manager Mr. Chen told reporters: "First of all, before the modification to their cars were very understanding, to know when the reserved car at the factory what kind of interface, or some kind of interface and the original car you have to install the device interface is generic; Secondly, the best choice in choosing special pieces of equipment that is supporting a model specifically for manufacturers of production equipment, in general, such special items are hot swappable, and the original vehicle interface, consistent, easy to install. again, looking for regular and reliable business to install, if possible, try to go to each device a separate insurance to ensure the safety of all vehicles. "Chen stressed that:" the principle of electronic devices to increase , that is, try not to touch the original car's lines. "

Try not to move the original car's lines, not only increase vehicle safety, while reducing second-hand car trading after the loss. In second-hand car trading is certainly Liu told reporters: "If you move off of the original car circuit, certainly not benefit from them, the same car, others can sell 50,000 yuan, you can sell 30,000 yuan, because other people not sure of your After the vehicles have changed line problems that will arise.

Be careful to install electric appliance in the vehicle

2010-04-07T13:57:00.000+08:00

Be careful to install electric appliance in the vehicle

Some people like to play car caused by "mobile home": car television, car refrigerator, car vacuum cleaners, air purifier and so on, peremptorily children to the car to install, and even mobile phones, laptop computers are the vehicle for charging car ... ... maintenance experts have warned that this practice is not desirable, hidden behind a risk that the quality of automotive electrical problems or if installed, used improperly, may damage your car.

The owner does not recommend self-installation

To facilitate the reverse, many car owners will install parking sensor. In this regard, Jinhua Day Pass Refine car 4S shop service manager Jian Zheng Wei said: "In general, to install the car parking sensor, car DVD type of electrical problems are not big, but be sure to buy good quality products with high credibility, Do not yield to the temptation to buy cheaper no-name. "

"Need to remind that, as these appliances during the installation process may be involved in car circuits in the Pu Tong owners better if regular service station professionals Anzhuang, do not install their own electric car, especially when the modified car stereo." Zheng Jian Wei said, "vehicle electrical installation, if the connection is not standard, installation is not strong, or even take the wrong line seal failure, it could cause a short circuit burned out the fuse at worst, the destruction of electrical equipment, while in a fire."

Caution car inverter

Some car owners to be able to phone in the car, laptop charging, will install a car inverter in the car. It is understood that a car inverter can the car 12V (diesel vehicles to 24V) DC into 220V AC devices, with it, you can use in the car often to use the electrical appliances at home, at the same time recharge the battery.

"People buy car inverter, be sure to choose a good brand, because of poor vehicle quality inverter working for some time, easy heat, hot, summer high temperatures inside the car may explode." with industry experts cautioned that the existing 12V car voltage, even if the owners of the injury problem is not great, but if the voltage into 220V, once the inverter is a problem, the consequences may be severe, "In addition, When using the inverter in the car should pay attention to timely plug Department cleaning up dirt, so as not to cause poor contact or abnormal converter overheating. "

After stopping less desirable electric car

The car is moving process, the engine rotation produced by a variety of automotive electrical power enough to be used. However, after stopping, the engine will not generate electricity, all electric appliances are all derived from the car battery car. At this time, car owners should be minimal use of electrical appliances, not to open at a time to a variety of automotive electrical, because the car battery capacity is not that big, and the battery will gradually aging, charge capacity will become increasingly less over once the vehicle electrical power consumption more, will lead to no electricity and can not start car.

SPWM waveform achievement based STC series MCU (part 2)

2010-03-25T12:12:00.000+08:00

SPWM waveform achievement based STC series MCU (part 2)

2.2 SPWM wave generation method

STC Series MCU produced using the basic principle of SPWM wave is: The value assigned to the carrier cycle, PCA module l, 16-bit capture / compare module register CCAPlH (high 8 bits), and CCAPlL (low 8 bits), PCA timer value of CH ( High-8), CL (low 8) and the modules capture registers compared to the value, when the two are equal, resulting in PCA interrupt. In the break, the call to the module 0 of the PWM pulse width modulation mode, the next one SPWM wave pulse through the CCAP0H loaded into CCAPOL, so that can be achieved without interfering with the update PWM.

Figure 3, namely, real-time calculation by the software a good way unipolar SPWM pulse waveform diagram. A fixed carrier in each cycle, different pulse width values to form a sine form of a table. If the selected module O (P3.7) output of this road SPWM, first PCA Module 0 Mode Register module is defined as the 8-bit PWM mode, the 16-bit counter timers CH, CL Clear, PCA PWM mode Auxiliary register O-ching zero (to ensure capture register EPCOH (high 8), EPC0L (low 8) fixed to zero, PWM wave numerical comparison only with the PCA module 0 capture register CCAPOH (high 8), CC2APOL (low 8) related) , the module l capture register CCAPlH (high 8), CCAPlL (low 8) into the carrier cycle, the high-and eighth 8-bit values, PCA compare / capture module register 1 (CCAPMl) is defined as to be able to compare features, allowed to match the generated interrupts. A pulse-width value of the first sin [0] into CCAP0H, open-PCA modules and low voltage detection interrupt interrupted, open a total break, start PCA count. When the 16-bit counter / timer value and the module 1 capture / compare register values are equal, resulting in a CCF interrupt; to interrupt program, clear interrupt flag bit, to re-register to the module 1 capture CCAPlH (high 8) , CCAPlL (low 8) into the carrier cycle, the high value of 8 and the eighth will be 16-bit counter timers CH, CL cleared, interrupt number of i plus 1, the next a pulse-width value of sin [i] loaded into CCAPOH to prepare for more. Arrive at the same time to determine whether the maximum number of N, if so, interruptions i cleared, while the number of pulse-width-sin [i] value into CCAP0H, to complete a cycle. This cycle, in the P3.7 pin will continue to produce changes in the law as the sine pulse, and thus accurate SPWM wave.

2.3 Software Design

KeilC51 programming using programming languages, and the whole process from the main program and the keyboard interrupt subroutine, as well as the composition of PCA interrupt subroutine. The main program in the system initialization entered SPwM pulse width calculation program to calculate the appropriate pulse width to form a sine table, waiting for interrupt flag bit in response to the different interrupts. SPWM wave is constant because the output must be set to the highest level of PCA interrupt. Once a PCA interrupt flag bit, that is transferred to the implementation of its interrupt subroutine. Figure 4 for the PCA interrupt subroutine flow chart. In the interrupt service routine, pay attention to CCF1 bit and CF flag set by the hardware bit, but can not automatically cleared, you must interrupt the program cleared by software.

At the same time, the system can respond to the keyboard interrupt subroutine from the keyboard to control the output voltage through the liquid crystal display monitors, the current changes and so on.

The two complement each other with the direct signal path driver chip MIC4421, the output signal and then drive power inverter, respectively, after low-pass filtered waveforms shown in Figure 6.

4 Conclusion

Experimental results show that this method the circuit structure is simple, practical hardware design and software programming. Use of online technology, combining computing and look-up table, the better solution of the real-time control requirements. At the same time use of SCM as a control device, not just cost reduction, but also convenient debugging, subject to outside interference small, has good practicability and reliability.

Key words: STC12C5410AD; SPWM wave

0 Introduction

In recent years, with the power inverter applications in all walks of life increasingly widespread use of sinusoidal pulse width modulation (SPWM) inverter technology for the control to improve the control effect of the whole system is that people continue to explore the issue. SPWM control for a variety of implementations, one is analog circuits, digital circuits and other hardware circuitry generates SPWM waveform, the waveform of the method stable and accurate, but the circuit complexity, size large, can not be auto-adjustment; the other is with MCU, DSP and other micro-controller to achieve the number of SPWM control method, because of its internal integration of a number of control circuits, such as the PWM circuit, programmable counter array (PCA) and so on, makes this method has a control circuit is simple, fast, anti - the advantages of strong interference. This paper presents a series of single-chip microcomputer using STC method of SPWM waveform will be generated by the STCl2C5410AD unipolar SPWM wave applied to single-phase inverter power supply, test results show that the use of the feasibility of its implementation and effectiveness of SPWM waveform.

A sinusoidal pulse width modulation SPWM

SPWM control scheme, there are two: the unipolar and bipolar modulation modulation. France obtained unipolar SPWM signals positive, negative, and 0 of three levels, while the bipolar received only positive and negative two kinds of levels. Comparison of the two resulting SPWM waves we can see: in the same carrier than the case, the resulting bipolar SPWM wave contained in the large amount of harmonics; and in sinusoidal inverter control, bipolar SPWM wave control complex. Therefore, commonly used in the form of unipolar SPWM wave control.

SPWM controlled by the MCU, in accordance with its software, the different methods, there are several ways: natural sampling method, symmetry rules of law, rules of law and the area of asymmetric follow suit and so on and so on. Theoretical analysis showed that an area equivalent in terms of law in regard to other methods, harmonic minor, harmonic suppression ability. And real-time control simple and conducive to software implementation. Therefore, size, etc. In this paper, follow the example of realization of SPWM control.

Suppose the required output sinusoidal voltage U0 = Umsinωt, type in: Um for the sine-wave amplitude. Follow the example of the use of an area so small an area of sine-wave pulse area S1 and S2 correspond to the same principle, with the positive half cycle sine wave is divided into N equal portions, each of equal portions with a width of Wu / N, calculate the half-cycle N different pulse width values.

2 STC series microcontrollers generate SPWM Wave Principle

About 2.1 STC Series MCU

STCl2 Series MCU U.S. STC in 8051 improved on the basis of the standard kernel introduced an enhanced 8051 microcontroller functionality, from the pin to the instruction is completely compatible with the 8051. The most prominent feature is its programmable counter array PCA. To STCl2C5410AD, for example, there are four Programmable Counter Array PCA / PWM. PCA includes a special 16-bit timers, there are four 16-bit capture / compare modules associated with it. Four blocks of public time base the decision by the PCA timer, you can register through the PCA model CMOD SFR bits of CPSl and CPS0 determined. Each module programmable work in four kinds of modes: rising / falling edge capture, software timer, high-speed pulse output or PWM output. Paper SPWM generation function mainly relies on the completion of PWM pulse output mode. Figure 2 namely PCA module pulse width modulation PWM output mode block diagram.

In the PCA PWM output mode, when CLSFR's value is less than (EPCnL, CCAPnL), the output is low, when the PCA CL SFR is equal to or greater than the value of (EPCnH, CCAPnH), the output is high. When the value of CL overflows from FF to 00 hours, (EPCnH, CCAPnH) content onto the (EPCnL, CCAPnL) in the. This update enables interference-free PWM. Can make the PWM mode, the module CCAPMn register PWMn and ECOMn bits must be set. In this article, SPWM waveform is the integrated use of the module O, pulse width modulation (PWM) mode and the module 1 of the 16-bit software timer mode, software interrupts in the form of implementation.

At the same time, STCl2C54lO microcontroller also has a fast A / D conversion. There is a lO-bit precision, 8-way channel A / D converter. Can be easily input and output voltage, current monitoring and display.
