摘要：
The integration of nine-phase permanent magnet synchronous machines (nine-phase PMSMs), employed in on-board integrated battery charger for electric vehicles (EVs), into three-phase grid generates an inevitable torque fluctuation in charging and vehicles to grid (V2G) modes. This undesirable torque, which is the source of motor vibration and noise, is due to the interaction among the zero-sequence current, triplen harmonics (third and ninth) of induced back electromotive force, and rotor position. In this article, a new solution for nine-winding integrated battery chargers of EVs is considered. A segmented three-phase PMSM with nine windings is used to replace the nine-phase PMSMs. With this configuration, the system has the advantage of torque-free in charging/V2G mode, low core loss, and simple control (based on the three-phase control) in both traction and charging/V2G modes, with the privilege of employing the reduced number of sensor and with no additional new elements. Through proper three-phase control strategy, the system operates under unity power factor with total harmonic distortion below 5%. Control strategies for charging, V2G, and motoring are given; moreover, the simulation and experimental results are provided to validate the theoretical analysis.
