With rated currents of up to 3,600A, the SKiiP4 module is the most powerful IPM available. It is one third more powerful than a SKiiP3 version with the same mechanical dimensions. SKiiP4 modules are ideal for use in wind and solar power applications and others with power ratings of 400 kW to 1.8 MW. The company says the units have five times the thermal-cycling capability as conventional modules.
A Chinese wind-power company, Xinjiang Goldwind Science & Technology Co. Ltd, has agreed to purchase advanced electrical equipment from Germany-based, local manufacturer Semikron China. The intelligent power modules and complete Semistack power electronic assemblies will come from Semikron China. The power modules, called SKiiP, are optimized for wind-power applications. Semikron says the modules are the most powerful intelligent power modules on the market capable of a long service life. In addition, Semistack power assemblies boast a high power density of 12 kW/liter and a flexible modular design.
For comparisons, the SKiiP4 power packs are said to deliver up to a third more power than the SKiiP3 modules. The latest versions have been improved for a maximum rated current of 3,600 A at a maximum voltage of 1,700 V. A 1,200-V version of the SKiiP4 is also available. This order further seals the business partnership of Goldwind and Semikron (offices in Hudson, NH), which provides equipment for the growing Chinese wind energy market.
Goldwind is one of the first enterprises in China focusing on innovative research and manufacturing for wind turbines. Since 2000, the company has had an average annual growth of 100% for the last ten consecutive years. The company was one of the top five global suppliers of wind power generators with a market share of 7.2% of the newly installed wind power capacity in 2009.
“It is an honor to be the supplier for Goldwind,” says Lixin Ren, managing director of Semikron Greater China. “Semikron technology powers nearly half of the globally installed wind-power capacity and Goldwind is one of the top five wind turbine manufacturers in the world. Our goal is to establish a long-term business relationship providing the most efficient technology and best service beneficial to both companies.”
“The state-of-the-art technology, reliable product quality, and professional technical support of Semikron met our high standard of requirement,” says Goldwind Supply Chain Manager Kai Wu. “Semikron`s experience in stack design and production gave us confidence that we can work together and achieve long-term success.”
China has the world’s largest wind power capacity. In 2009, 13.7 GW of wind power was installed thereby more than doubling the cumulative installed capacity in a single year, which has now reached 25.8 GW (Source: BTM Consult ApS, March 2010).
Semikron adds that its technology powers nearly half of the globally installed wind power capacity. According to a survey carried out by BTM Consult ApS, the total wind power capacity installed until 2009 was 122 GW, with 57 GW comprising semiconductors from Semikron. In 2009 the company formed a 50/50 joint venture with Magna Electronics to develop and produce inverters and chargers for electric and hybrid vehicles.
