In the HVdc circuit breaker testing process, a thyristor is used to generate high current for the testing purpose. However, the reverse recovery process (RRP) of a thyristor can induce a significant ...

In this letter, a novel solid-state circuit breaker (SSCB) based on mixture device (MD-SSCB) is proposed for dc distribution systems. The proposed MD-SSCB can actively interrupt faults without ...
