Silicon Carbide MOSFETs for Medium Voltage Megawatt Scale Systems

Due to their low switching energies, knee-less forward characteristics, and a robust, low reverse recovery body diode, SiC MOSFETs are ideal candidates to replace silicon IGBTs in many high-power medium-voltage topologies. This paper demonstrates how SiC MOSFETs can be effectively combined in series and parallel to maximize the system power density and performance.
