Abstract

The invention discloses a switched reluctance motor control system integrated with driving and power battery charging, comprising a rectifier module, a driving module, a first contactor and a second contactor for on-off control, and a control module. The positive DC bus bar of the rectifier module is sequentially connected to the positive electrode of the vehicle-mounted power battery through thefirst contactor and the second contactor, and the negative DC bus bar is connected to the negative electrode of the vehicle-mounted power battery. The positive DC bus bar of the rectifier module is connected to the negative electrode of the vehicle-mounted power battery through the first contactor and the second contactor. By controlling the switching transistor of the motor controller, the contactor can realize the driving of the switched reluctance motor, and the charging functions of two modes of boosting and decreasing the voltage of the power battery when the electric vehicle is stationary, thereby realizing the multiplexing of the devices and reducing the cost and the space occupation.

Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a switched reluctance motor control system and control method integrating drive and power battery charging. Background technique [0002] Due to its simple structure, large starting torque, and good fault tolerance, switched reluctance motors are highly competitive motors in the field of electric vehicle applications. The switched reluctance motor drive system includes a vehicle power battery, a DC capacitor, an N-phase motor winding, a drive circuit power electronic switch tube and a diode. Usually, the switched reluctance motor controller only has the motor driving capability, and an independent charging circuit is required to charge the vehicle power battery, resulting in high cost and inconvenient use. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, to provide a switched reluctance ...
