6.5kV FREEDM-Pair: Ideal high power switch capitalizing on Si and SiC

Abstract

6.5kV Si IGBTs have been used widely in median voltage drives, HVDC, FACTs and traction systems. However, the large switching losses of the Si IGBT limit its switching frequency to only 100Hz to 1kHz. On the other hand, wide bandgap (WBG)power devices such as Silicon Carbide (SiC) MOSFET or JFET have demonstrated their superior advantages over Si IGBT… (More)
