We have developed a prototype of a 3-kV/200-A SiC hybrid module, equipped with Si IGBTs and SiC Schottky barrier diodes. We have achieved a reduction in the recovery loss and turn-on loss by using a SiC hybrid module and decreasing the turn-on time by lowering the gate resistance. Moreover, we estimated that the total energy loss of the converter and inverter using the developed SiC hybrid module was reduced to approximately 30%. Additionally, the inverter succeeded in driving an induction motor for a train.
