Abstract:
A new test method is introduced that targets bipolar degradation of SiC MOSFET devices during short dead time phases. The approach offers strong scalability and acceleration, considers application-compliant conditions, and can cover current levels several times beyond the nominal current. Initial tests at short dead times are presented, analyzed, and compared with corresponding worst-case reference tests under DC conditions.
