From the perspective of power systems, photovoltaic technology focus in the following two aspects. First, PV systems from the perspective of the photovoltaic industry is one of the greatest challenges facing the shadow of the issue of solar panels. Changes in shadow, solar panels on the dirt and the aging panel, each panel will be on the impact of voltage, causing the output voltage in series panel changes. Micro-inverter will be one of alternative solution, it can achieve the panel-level maximum power point tracking (MPPT), has advantages beyond the central inverter. MPPT solar panel can get the best of each block of the power point without the need for serial solar panels in series configuration, you can minimize the shadow problem. Second, from the perspective of power devices, due to major PV system manufacturers have their own patent application PV inverter topology, semiconductor suppliers to develop specific products. Therefore, these vendors need to keep up with the evolving solar inverter market, emerging technology trends. For example, the need to enhance the input voltage to obtain higher efficiency, so you must use 650V or more MOSFET / IGBT. There is also need to use SiCSBD as a complete solution. In addition, more than 10kW to expand market share, you must use the IGBT / SPM module.

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
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.
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.

The Smart Grid is facing two major challenges
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.

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
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.

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.

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.

Online interactive UPS
.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.

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.

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
