SiC power module boosts inverter efficiency

A 1.2kV all-SIC six pack module enables an increase in the power rating of inverters to 50 per cent while reducing power losses by 50 per cent to increase efficiency by 5 per cent. The device is based on Cree’s C2M SiC MOSFET and Z-Rec SiC Schottky diode technology. The all-SiC 1.2 kV, 20A six-pack features the industry’s lowest switching losses due to the zero turn-off tail current in the MOSFET and the zero reverse recovery current ...
