The invention discloses a switched reluctance motor driving and charging integrated system which comprises a storage battery, a power converter, a switched reluctance motor, a rectifier bridge and a filter. According to the power converter, a follow current bus is additionally arranged on the basis of a conventional asymmetric half-bridge circuit, and meanwhile, a driving and charging change-over switch tube and a diode are additionally arranged on an original excitation bus; in the driving mode, the asymmetric half-bridge circuit works normally, the excitation loop and the follow current loop are separated, and conversion from electric energy to mechanical energy is achieved. In a charging mode, an external power supply is connected with the excitation bus and the power converter through the filter and the rectifier bridge, external alternating current can obtain direct current after being rectified by the rectifier bridge, the power converter of the motor is reused as a direct current converter, and parallel interleaved boost or buck buck charging of storage battery boost is realized. According to the invention, the volume of the system, the current ripple, the current stress of the device and the switching frequency of the switching device are reduced.
