Intelligent power module

Semistack_RE is an intelligent power module (IPM) targeting synchronous and double-fed induction generators (DFIG) in wind turbines, and central solar PV inverters.

The water-cooled threephase converter comes in B6CI two-quadrant or 2 × B6CI four-quadrant configurations in a bookcase-type mechanical design.

The previous version of Semistack-RE based on the three-bay version of SKiiP 3 has a current capability of 1,200 /module. The bigger, four-bay SKiiP 4 version has a current rating of between 1,000 and 1,400 A.

SKiiP 4’s new digital gate driver provides a safe electrical isolation between primary and secondary side for all switching or control signals and for the temperature signal. The SKiiP driver features a CANopen setup and diagnosis channel, giving access to an error memory so errors in SKiiP 4 can be quickly identified and saved for later diagnosis.
