1700V Hybrid Module with Si-IGBT and SiC-SBD for High Efficiency AC690V Application

This paper describes about newly developed 1700V/400A hybrid module which consists of Si-IGBT and SiC-SBD. The static and dynamic characteristics were evaluated and the turnon loss is 38% lower and the reverse recovery loss is 83% lower than the conventional all-Si IGBT module. The peak value of the radiation noise from the hybrid module is almost same as the all-Si module if the collector current is less than 300A. Power dissipation losses of the hybrid module in AC 690V inverter system were calculated and confirmed that the module is useful as a power module for high efficiency AC690V inverter system.
