WebThis paper investigates a degradation of SiC power device for DC circuit breaker through repetitive unclamped inductive switching (UIS) tests. Being much lower compared with Si devices, it has been considered an application for DC circuit breakers using SiC semiconductor. In order to use for the DCbreaker, it is essential to evaluate the destructive … WebThe reliability of gate oxides is a fundamental issue for realizing SiC MOSFETs. Many reports said that crystal defects shorten the lifetime of the gate oxide. And, epi defects, the basal plane dislocations and threading screw dislocations (TSD) are considered killer defects. However, because of the high TSD density of commercial SiC wafers, the exact …
