High-Performance IGBT Modules

Semikron SkiiP®4 uses EPCOS capacitors to eliminate overshoots

 Intro Pic

IGBT manufacturer Semikron uses EPCOS DC link and snubber capacitors on his latest development, the SkiiP®4 high-performance module, which switch currents in the kA range. At this performance level unwanted and in some cases harmful voltage overshoots can occur due to DC link leakage inductances. To counteract this, TDK offers extremely low-inductance snubber and DC link capacitors.

With its latest development, the SkiiP®4 IGBT module manufacturer Semikron has optimized both design and performance. The new model has a DBC concept (Direct Bond Copper) with no base plate and on a high-performance-cooler (heatsink). As a result, the power module SKiiP2414GB17E4-4DUHP, which is made up of four half bridges, can now switch up to 25 percent higher currents of significantly more than 2400 A at a voltage of up to 1700 V at the IGBT.
