摘要： The present disclosure provides a hybrid circuit breaker having a bridge induction transfer structure, characterized in that the circuit breaker comprises a main current circuit, an over-voltage limiting circuit, and a transfer current circuit; and the main current circuit, the over-voltage limiting circuit, and the transfer current circuit are connected in parallel. The induction transfer circuit in the transfer current circuit comprises an induction transfer inductor, an induction transfer capacitor, and an induction transfer branch power semiconductor device which are connected in series; the transfer current circuit further comprises a bridge circuit comprised of a main loop capacitor; the main loop inductor and the induction transfer inductor are coupled to form a transformer. The present invention can implement fast breaking of the current, and effectively reduce the volume and manufacturing cost of the circuit breaker. With the induction transfer circuit, fast current transfer is implemented. The main loop capacitor needs no pre-charging. Isolation between the secondary charging circuit and the main loop is implemented. The transfer speed is fast, and the breaking reliability is high.
