具有自重启能力和能量回馈的双向串联型直流混合断路器

The series hybrid circuit breaker (SHCB) is a promising solution for fault current breaking in medium and low-voltage dc distribution networks, offering fast fault breaking and low conduction losses. However, the additional circuits or devices required for charging the energy storage (ES) capacitors complicate the restart operation of the SHCB, and the dissipation of large amounts of residual magn...
