A New Z-Source DC Circuit Breaker

A novel type of circuit breaker is introduced for operation at medium-voltage dc with future naval ship power systems as a targeted application. The breaker utilizes a z-source LC circuit in order to automatically commutate a main-path SCR during a fault. Compared to existing dc circuit breakers, the z-source breaker features fast turn-off, simple control, and the source does not experience the fault current. The operation and analysis of the new breaker is presented. Component sizing is carried out for three medium-voltage power levels. Incorporation of the new breaker within a drive system is also explored. Laboratory validation is carried out on a low-voltage prototype.
