Abstract: A motor driving and battery charging apparatus is provided. The apparatus includes a motor having a plurality of coils, a rectifier circuit connected to the plurality of coils, and a high voltage battery. An inverter generates a driving current from an output voltage of the high voltage battery and supplies the driving current to the motor while the motor operates. While the high voltage battery is charged, the rectifier circuit rectifies an alternating current (AC) of an external power source, the motor and the inverter compensate for a power factor of the current rectified by the rectifier circuit, and the high voltage battery is charged with an output current of the motor and the inverter.
