摘要：This paper proposes an integrated on-board charger for electric vehicles (EVs) that incorporates anasymmetrical nine-phase machine and an inverter into the charging process. The charging is from three-phase mains,and it employs exclusively the power electronic components that already exist on-board the vehicle, and that aremandatory for the propulsion. Moreover, the charging is achieved without any hardware reconfiguration since theexisting elements and their connections are not altered during the transfer from propulsion to the charging mode.Instead, the operating principle is based on additional degrees of freedom that exist in nine-phase machines. Thesedegrees of freedom are employed to avoid electromagnetic torque production in the machine during the chargingprocess, although currents flow through its stator windings. The configuration operates with a unity power factor and iscapable of vehicle-to-grid (V2G) operation as well. A detailed theoretical analysis is given, and the control for thecharging/V2G and propulsion modes is discussed. Theoretical analysis is validated by experiments for charging, V2Gand propulsion operating regimes.
