一种具有简单启动操作和低器件成本的低压直流配电网新型串联混合断路器

The series-type hybrid circuit breaker (S-HCB) is an effective solution for ultrafast dc fault protection. However, the introduction of multiple energy storage (ES) capacitors and fully controlled power devices for zero-current modulation leads to complex startup operations and significant-increased costs. In this article, a novel S-HCB with simple startup operation and low device cost for low-vol...
