Embodiments of the present disclosure relate to multi-port solid state circuit breaker devices, systems, and methods. A multi-port solid state circuit breaker system includes a first power bus, a second power bus, and a plurality of circuit breaker branches conductively coupled in parallel with each other with the first power bus and the second power bus. Each of the plurality of circuit breaker branches includes a first power semiconductor device coupled in series with a second power semiconductor device and an input/output port intermediate the first power semiconductor device and the second power semiconductor device. At least one of the first semiconductor device and the second semiconductor device includes an actively controlled switching device. The surge suppressor is conductively coupled in parallel with the plurality of circuit breaker branches.
本公开的各实施例涉及多端口固态断路器装置、系统和方法。多端口固态断路器系统包括第一电力总线、第二电力总线以及彼此并联地与第一电力总线和第二电力总线导电耦合的多个断路器支路。多个断路器支路中的每个包括与第二功率半导体器件串联耦合的第一功率半导体器件以及在第一功率半导体器件与第二功率半导体器件中间的输入/输出端口。第一半导体器件和第二半导体器件中的至少一个包括有源控制的开关器件。浪涌抑制器与多个断路器支路并联地导电耦合。
