The invention discloses a switched reluctance motor driving and charging integrated system without an electrolytic capacitor, which comprises a storage battery, a bus filter capacitor, a power balance circuit, an asymmetric half-bridge circuit, a switched reluctance motor, a driving/charging change-over switch and a rectifier bridge, the circuit is composed of two switching tubes, a capacitor and a high-frequency inductor. In the driving mode, the power balancing circuit can eliminate pulsating power on a bus, so that the switched reluctance motor is driven without an electrolytic capacitor, and the reliability of the system is improved; and in a charging mode, the power balance circuit is multiplexed as a boost charging circuit of the storage battery, so that driving/charging integration of the switched reluctance motor is realized, and the size of the system is reduced. The method can be compatible with a direct-current power supply and an alternating-current power supply, and is suitable for switched reluctance motors with any phase number.
