Traction Inverter that Applies Hybrid Module Using 3‐kV SiC‐SBDs and High‐Speed Drive Circuit

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