Inverter Loss Reduction Using 3kV SiC-JBS Diode and High-Speed Drive Circuit

Abstract:

Article Preview

We developed a JBS diode with characteristics of a low forward voltage and a low leakage current at 3kV. Further, we built a prototype of a 3kV/200A hybrid module, equipped with Si-IGBTs and SiC-JBS diodes. We attempted to decrease the recovery loss, and the decrease in the turn-on power loss, by using a hybrid module and a high-speed drive circuit. Moreover, we estimated that the total energy loss of the converter and the inverter were reduced to about 33%.
