Abstract:

The rapid development of low voltage DC system puts forward the higher requirements for the breaking performance of the traditional circuit breaker.The use of power electronic devices provides a new idea for the development of DC circuit breaker.This paper reviews the development status of two novel DC circuit breakers,provides a brief introduction of solid-state circuit breaker from the circuit topological structure and characteristic of power electronic devices,and summarizes the hybrid circuit breaker mainly based on commutation modes including zero-voltage switching and zero-circuit switching.Finally,the development prospects of novel DC circuit breaker is pointed out in the future including controlling strategy,module integration,breaking capacity and model simulation,which can provide a useful reference for the development of novel DC circuit breaker.

Key words: low voltage system, DC circuit breaker, solid-state circuit breaker, commutation mode
