A dc circuit breaker (DCCB) based on a superconducting current-limiting technology was proposed for the interruption of short-circuit fault currents in high-voltage dc (HVDC) systems. The proposed DCCB includes a superconducting current-limiting module (SCLM), which is used to limit fault currents, and an interrupter module (IM), which uses a self-excited oscillation method to interrupt the limited...
