Abstract :
An integrated motor/drive/battery charger is proposed, designed and simulated for vehicles using grid power to charge the system batteries. The machine stator windings are re-configured by a relay-based switching device for charging to constitute a special grid connected generator. This rotary generator (machine with re-configured windings) provides an isolated three-phase power source for the inverter to make a three-phase boost battery charger. The system design and operation in the charging and traction modes are explained for the proposed integrated motor/drive/battery charger. The charging power is half of the traction power for the proposed system. Simulation results are provided to verify the proper operation for the proposed system.
