摘要

This letter presents a new auxiliary circuit to achieve transient current commutation (TCC) in dc solid-state circuit breakers (SSCBs). The auxiliary circuit consists of two parts: active injection circuits (AIC) and capacitive couplers. There are two contributions. First, coupling capacitors between AIC and the main branch are introduced to prevent short circuit failures in the auxiliary branch. ...
