This paper presents a safe charging operation for the integrated on-board electric vehicle (EV) charging system, where the power electronic components are reconfigured from the propulsive system. First, the rotational movement is detected and analyzed, when the motor windings are reutilized as the dc-dc inductors. Then the safe charging operation is investigated, which is based on the analysis of the charging torque and the ripple currents. Moreover, a new control strategy is presented with the purpose of the safe operation and smoothing reactor during the EV charging process. Finally, both simulation and experimentation are carried out to verify the safe charging operation. The results prove the feasibility and validity of the proposed safe charging operation for on-board charger with the three-phase interior permanent-magnet motor.
