Abstract:
The present invention provides a direct current circuit breaker and its implementation method, which includes a cutout circuit, a commutation circuit and a energy absorption circuit connected in parallel. Through using power semiconductor switch module to cut off the current, it will have a quickly action, without generating electric arc, while the modular construction also reduces the consistency requirements of the power electronic component.
