具有软重合闸能力的多端口晶闸管直流固态断路器

Thyristor-based dc solid-state circuit breakers (T-SSCBs) have been widely investigated due to their low losses and low cost. However, the current solutions are not cost-effective in dc microgrid because the number of auxiliary devices [e.g., auxiliary thyristors, capacitors and metal oxide varistors (MOVs)] will significantly increase in multiport scenario. In this article, a novel T-SSCB topolog...
