1 Introduction Background

In current EV/HEV high-power inverter application scenarios, the probability of IGBT or SiC module short-circuit failure occurs due to overcurrent, overvoltage, overheating, device aging and other factors. Traditional driver schemes only realize short-circuit protection with Desat during system operation and cannot detect whether the module has failed before startup. Operation with faults directly leads to secondary faults, which greatly increases system safety risks. Therefore, preventive safety detection has become an industry rigid demand.
