3.3kV All-SiC Module for Electric Distribution Equipment

We developed 3.3kV All-SiC power module on which SiC-MOSFET and SiC-SBD were applied for electric distribution equipment. This power module has characteristic structure of pin-connection and resin-molded package. These features lead to long-term reliability. In addition, low static loss and low switching loss is achieved by using SiC devices. Total switching loss of All-SiC module in the inverter driving is 64% lower than a module which uses Si-IGBT and Si-FWD.
