一种采用二极管钳位开关的单耦合注入式串联混合断路器

The series-type hybrid circuit breaker (S-HCB) is an attractive solution for fault protection in medium and low-voltage dc distribution networks, effectively suppressing fault current rise during breaking while maintaining low conduction losses. However, their multilevel injector used for active current modulation suffers from complex topology and control, while the mechanical switch's (MS) curren...
