Crowbar circuits have long been the go-to safeguard against overvoltage conditions, prized for their simplicity and ...
Abstract: Hybrid dc circuit breaker (HCB) is an effective device for interrupting dc fault currents in dc grids. Conventional two-port HCB requires too many insulated gate bipolar transistors (IGBTs) ...
Abstract: The objective of this paper is to propose a dc current interruption technology for railway dc traction systems, consisting of a dc vacuum circuit breaker with a superconducting fault-current ...
