New power system components and controls are needed to facilitate the US Navy's move to MVDC systems on future
vessels. Integrating the z-source circuit breaker into a "typical" naval MVDC power system requires understanding system
dynamics that may cause the breaker to inadvertently energize a circuit through regenerative turn-on of the thyristor. A
scale model and a simulation model are used to characterize voltage transients that could lead to this false triggering. Limits
in the breaker's protective capabilities during turn-on transients are identified. Topology modifications, control schemes, and
power system arrangements that provide protection across the operating range are proposed for further investigation.
