Electric vehicle switch reluctance motor driver possessing charging function

Abstract

An electric vehicle switch reluctance motor driver possessing a charging function belongs to the switch reluctance motor technology field. The driver is characterized in that the driver comprises a direct-current power supply, a boost unit, a voltage reduction unit, multiphase winding control units and a control system which controls the boost unit, the voltage reduction unit and each phase of winding control unit; the direct-current power supply is connected to the boost unit and the voltage reduction unit simultaneously; the boost unit and the voltage reduction unit are connected to each phase of winding control unit simultaneously; each phase of winding control unit is connected to a corresponding winding in a switch reluctance motor respectively; and a charging interface is connected in parallel between each phase of winding control unit and the corresponding winding in the switch reluctance motor. Through the electric vehicle switch reluctance motor driver possessing the charging function of the invention, the switch reluctance motor can be driven to work; simultaneously, the direct-current power supply in the switch reluctance motor can be charged; and charging flexibility of an electric vehicle is increased, which is good for electric vehicle popularization.

Description

technical field [0001] The utility model relates to a switched reluctance motor driving device with a charging function for an electric vehicle, which belongs to the technical field of switched reluctance motors. Background technique [0002] In the electric vehicles of the prior art, the motor drive device and the charger of the electric vehicle are all set independently: in small and micro electric vehicles, the charging device is placed on the electric vehicle; in large electric vehicles (such as electric passenger cars) , put the charging device on the ground, and charge the large electric vehicles by a special charging pile. The way of placing the charging device on the car in small electric vehicles will take up a lot of vehicle space and increase the cost; while in the way of placing the charging device on the ground in large electric vehicles, electric vehicles need to go to special charging piles Therefore, the flexibility of electric vehicle charging is greatly re...
