Traction inverter that applies hybrid module using 3-kV SiC-SBDs
2010
We have developed SiC-Schottky barrier diodes with a JBS structure that have characteristics of low forward voltage and low leakage current at 3 kV. Further, we have built a prototype of a 3 kV/200 A SiC hybrid module, equipped with Si-IGBTs and SiC-Schottky barrier diodes. We have achieved to reduce the recovery loss and the turn-on loss, by using the SiC hybrid module and a high-speed drive circuit. Moreover, we estimated that the total energy loss of the converter and inverter using the developed SiC hybrid module was reduced to about 30%. Additionally, the inverter succeeded in driving an induction motor for a train.
