1. A charging apparatus comprising:

  • a converter configured to, in a charging mode, receive an input alternating current (AC) voltage and convert the input AC voltage into an output direct current (DC) voltage; and

    a controller configured to control the converter,wherein the converter includes;

    a motor that includes a stator, a rotor, and coils wound on the stator, the coils corresponding to a plurality of phases of the motor;

    an additional coil wound on a portion of the stator that corresponds to a phase of the plurality of phases of the motor;

    a switching unit connected to the additional coil and configured to, in the charging mode, selectively supply the input AC voltage or rectified voltage based on the input AC voltage to the motor by performing a switching operation; and

    an inverter configured to, in a motor operation mode, convert a battery DC voltage from a battery into an output AC voltage by performing a switching operation of three-phase switching elements and drive the motor, and, in the charging mode, convert the input AC voltage or the rectified voltage into the output DC voltage using the additional coil of the motor and the switching unit and supply the output DC voltage to the battery.
