  • Publication number: 20230170901
    Abstract: A thyristor-based dc solid state circuit breaker (SSCB) named Y-type includes a new complementary commutation circuit including a capacitor-capacitor pair, which features three advantages. First, a fast commutation is achieved using a countercurrent pulse injection by the capacitor-capacitor pair structure. Second, metal-oxide varistors (MOVs) are disconnected from the power line when SSCB is OFF, which solves the reliability issue due to the MOV degradation and enhances the voltage utilization rate of the main switch. Third, benefiting from the capacitor-capacitor pair structure, reliable reclosing and rebreaking are obtained for practical applications.
