Munich Shanghai Electronics Show in 2010 singing the main theme of power electronics technology




Copenhagen for the recently concluded meeting, the Chinese government introduced a specific quantitative policy, "By 2020, China's carbon dioxide emissions unit of GDP decreased in 2005 compared with 40% -45%." At the same time in 2010 the "Eleventh Five-Year" last year, the unit GDP energy consumption reduced by 20% of the target is also the need to achieve. In the "energy-saving emission reduction" policy, to quantify, "Eleventh Five-Year" in the final sprint of new renewable energy applications coupled with the continuous development of smart grid continued construction, hybrid and electric vehicle markets, such as a number of favorable factors to stimulate the common role of 2010, will be a great development of the power electronics industry for one year.



To meet this unprecedented development opportunities, comply with the will sing the main theme of power electronic technology beat, by the China Power Supply Society and Munich Trade Fairs International Group co-sponsored a comprehensive technical forum "China's Power Electronic Technology Application Development Forum" in 2010 March 16-17 annual Shanghai Electronics Show in Munich again during the grand opening, covering new materials, new devices, new devices, new systems, AC / DC motor drive and control, all kinds of new power inverter, as well as the latest applications for development and progress, in particular, will power electronics technology in the new environment, the role played by the new focus on the start.



To overcome the bottleneck of renewable energy applications



Along with renewable energy sources (such as wind and solar power field) the continuous development of distributed generation will become the whole power supply system an important part. With the use of conventional resources, costs continue to rise, the proportion of renewable energy sources will continue to rise. Many agencies predicted that by 2030, renewable energy in the global energy consumption share will be increased substantially. Among them, the U.S. Department of Energy Information Administration estimated that this ratio is about 8%, Greenpeace and the European Renewable Energy Council forecast is as high as 30%. China has also just December 26, 2009 by modifying the 2006 renewable energy law that requires power grid operators are required to purchase all renewable energy produced by electricity. This amendment would like to enhance China's renewable energy share, that is, to achieve by 2020 China's total generating capacity by 15%.



Compared with solar energy, wind power is a more stable source of energy, the strength of the wind is changing minute by minute, day, wind power is not in the same way throughout the year may be exposed to extreme heat, cold, and hurricanes. As a wind energy conversion and control of key devices, IGBT module to withstand the frequent power and temperature changes, which will shorten the life span IGBT. IEC60747 defines the parameters related to life, that power weeks time and temperature-week times, it is important IGBT module reliability index.



As an advocate of green energy sector, Infineon IGBT modules has been committed to the improvement of power density. With 10 years in the locomotive traction in the IGBT module experience, by means of fourth-generation IGBT4 chip module process technology and improvements to its maximum operating junction temperature from 125 degrees to 150 degrees, making the system energy efficiency ratio significantly increased, IGBT life expectancy has also increased significantly to meet the wind power and electric vehicles and other new applications demand. Currently used IGBT4 chip Infineon IGBT power modules weeks time than the previous generation products in the same working conditions, increased five-fold, the new packages, such as PrimePack ™ Temperature weeks time increased 7 times.



In addition to wind power market IGBT products, Infineon also has full-featured system components STACK products, including IGBT modules, driver protection, filter capacitor, dc bus, radiator and a series of inverter power unit. At present, they have succeeded in bringing the product into China, making China's wind power inverter manufacturers developed their own speed greatly improved, solving the biggest wind power supply chain bottlenecks.
