一种具有可靠开断过程的新型基于有源晶闸管的直流断路器

Replacing expensive IGBT with thyristor to design dc circuit breaker (dcCB) is attracting attention recently due to its advantages in terms of low investment and low conduction loss. However, due to the half-controlled characteristic of thyristor, the existing thyristor-based dcCBs (T-CBs) cannot be actively turned off. As a result, the opening process is not fully controllable and reliable. In th...
