Today, more then 350,000 wind turbines are in operation in the field world-wide. The demand for reliable spare parts to ensure continuous energy harvesting until the end of the turbine life is becoming increasingly important. SEMIKRON has a broad portfolio of products to ensure reliable operation and maintenance for wind turbine converters. From individual power modules, IPMs and drivers to dedicated, customized retrofit stacks – SEMIKRON has the right solution!


With more than 25 years of experience in the wind energy business, SEMIKRON equipped the first commercial wind turbines with highly reliable power electronic components. The first high-power IPM on the market, the SKiiP module, was an enabler for multi-megawatt wind turbines in the 1990s. With this long-term experience in the wind power sector, SEMIKRON now offers a broad portfolio of products to keep your wind turbine operating reliably.

This portfolio starts with industry standard power modules such as the SEMITRANS and SEMiX family. It includes SKiiP IPMs with customized coolers to fit into your wind turbine converter. The range is rounded off with highly reliable stacks based on solder-free SKiM 93 modules featuring sintered chips. This technology allows for optimized thermal conductivity from chip to heatsink and runs the chip at about 20°C lower than the OEM stack.

SEMIKRON also offers newly designed driver boards based on the latest SEMIKRON ASIC technology with digital signal transmission and additional protection functions. With 25 companies operating worldwide we can offer our products and service close to our customers.
