A High Power Density Inverter with hybrid sic module

Compared with the silicon power devices, silicon carbide(sic) power devices are expected to have a great impact on inverter efficiency, weight, volume and reliability. In order to research on the sic power devices, A hybrid module with si IGBT and sic schottky diodes was built. In this paper, characters of si diodes and sic diodes were shown. Than switch characters of the all si module and hybrid sic module were compared in double pulse platform. Finally, inverter loss of all SI inverter and hybrid sic inverter was tested, in the permanent magnet synchronous motor.
