Abstract

The invention discloses an N-type switched reluctance motor driving system and method based on wireless electric energy transmission. The system comprises a primary side electric energy transmitting device, a secondary side electric energy receiving device, an N-type driving circuit, and a switched reluctance hub motor, and the primary side electric energy transmitting device, the secondary side electric energy receiving device, the N-type driving circuit, and the switched reluctance hub motor are connected in sequence. Power is supplied to the switched reluctance motor in a one-to-one wireless power transmission mode, and complete isolation of the primary side and the secondary side is achieved. After the symmetrical T-shaped LCC compensation network is adopted, the voltage gain of the system is not changed when the load changes, but the voltage gain of the system is increased when the load is lightened under the actual condition, and when the winding is in the conduction stage, the current is smaller, the equivalent load is lighter, the voltage gain is increased, the winding can be quickly excited, and the torque ripple is reduced.

Description

technical field [0001] The invention belongs to the technical field of switched reluctance motor control, in particular to an N-type switched reluctance motor drive system and method based on wireless power transmission. Background technique [0002] Electric vehicles are developing very rapidly now, and wireless power transmission and in-wheel motors have been introduced into the application of electric vehicles. The use of in-wheel motors in electric vehicles omits a large number of transmission mechanisms, making the vehicle simpler, and can realize a variety of complex driving methods, which is convenient for the adoption of various new energy vehicle technologies. Traditional in-wheel motors are connected by wires, but the environment in which the cables are located is relatively harsh, and they are prone to disconnection and aging. Therefore, wireless in-wheel motors are produced. The body supplies power to the in-wheel motors in a wireless manner, avoiding this proble...
