Beschreibung
Zusammenfassung:	The invention provides a switched reluctance motor power control circuit. The switched reluctance motor power control circuit comprises a switched reluctance motor power conversion circuit, and the switched reluctance motor power conversion circuit comprises field switch tube and a freewheeling switch tube. The switched reluctance motor power control circuit is characterized by further comprising a freewheeling switch tube control circuit, the freewheeling switch tube control circuit comprises a control chip, and the freewheeling switch tube is controlled and triggered by the control chip. The switched reluctance motor power control circuit has the advantages that the problems of large power consumption, large size, difficulty in model selection and high cost of a freewheeling diode of the switched reluctance motor power control circuit in practical use are solved, energy loss is reduced, temperature rise of a power converter is lowered, and reliability, safety and efficiency of a system are improved.
