March 2022 – SEMIKRON’s Power Electronics for Motor Drives

Published on: 18/03/2022

Introducing Semikron’s power electronics for motor drives

Semikron semiconductor factory and machinery

Since their inception, Semikron has been committed to supplying solutions for every power range of motor drives. Starting with the first insulated power module, rectifier modules from the SEMIPACK series more than 40 years ago, the MiniSKiiP in particular has revolutionised the motor drive design for low and medium power systems. Completed with industry standard power modules such as SEMiX and SEMITRANS, the portfolio is made complete with high-power SKiiP 4 IPMs and power electronic stacks. The new generation 7 IGBTs boost performance and power density.
