Satability Point Analysis Of Integrated On-Board Charger Based On SRM

This paper presents a new structure for integrated motor drive and non-isolated battery charger of electric vehicles incorporating switched-reluctance motor (SRM). For the electromagnetic torque of the motor in the charging mode, this paper studied the way of inductance current based on the motor winding structure and through the physical model and properties of the motor, the rotor angle of the motor in single-phase, two-phase and three-phase charging is calculated to solve the problem of rotor rotation. The innovation of this method is to achieve voltage-boosting and power factor correct (PFC) of the battery. The specific control block diagram of inductance current instantaneous control of integrated on-board charger based on SRM is proposed, and the stability of the control system is judged by Routh criterion.
