用于具有单开关属性的固态直流断路器的超低通态电压IGCT

The performance of solid-state dc circuit breaker (SS-DCCB) is mainly determined by the on-state feature of power device. In this article, an optimized low on-state voltage integrated gate-commutated thyristor (LO-IGCT) for SS-DCCB is developed. First, the impacts of device parameters, including base length, carrier lifetime, and emitter injection efficiencies, on on-state voltage are presented. T...
