Abstract
A charging system using a motor driving system, the motor driving system including: a battery and an inverter, the inverter configured to receive and convert a direct current (DC) power stored in the battery into a three-phase alternating current (AC) power and to output the three-phase AC power to a motor when the motor is driven and the motor configured to generate a rotation force using the three-phase AC power output from the inverter, the charging system includes a controller configured to control the inverter to boost a voltage at a neutral point of the motor and to output the boosted voltage to the battery by determining duty values of switching elements in the inverter when an external charging current is provided to the neutral point of the motor.
