Abstract

The development of the DC microgrid system has promoted the development of the DC circuit breaker. However, the traditional DC circuit breaker exists many problems such as long period of fault interruption, complex circuit structure, existing arc, low reliability and low anti-interference. Aiming to solve these problems, an improved solid-state DC circuit breaker was proposed in this paper. This improved solid-state circuit breaker uses a transformer instead of LC legs which exist in the traditional Z-source circuit breakers to realize the function of turning off the thyristor. The working principle and designing process are discussed in this paper according to the results of simulation based on Saber. And the operation performance of the improved solid-state circuit breaker is validated by the calculation and simulation results.
