Characteristics of the power electronics equipments applying the SiC power devices

Abstract

Power Electronics Equipments applying superior characteristics Silicon Carbide (SiC) power semiconductors have been researching and developing. Applying the hybrid modules using Si-IGBT and SiC-SBD (Schottky Barrier Diode) to the motor drive inverter enables reduction of the loss 25% of the inverter part. Moreover applying the All-SiC modules using SiC-MOSFET and SiC-SBD to the solar inverter enables to be the efficiency of the main circuit unit 99%, and to be the volume of the equipment 25% to conventional one.
