Abstract: Disclosed herein is a charging apparatus for an electric vehicle. The charging apparatus includes a motor generating a power for vehicle driving. An inverter supplies a power to the motor. An alternating current (AC) power input stage receives an AC input power from among a single-phase AC power and a multi-phase AC power. A power factor corrector includes full bridge circuits receiving the AC input power through the AC power input stage. A link capacitor is charged through a combination of the power factor corrector, the motor, and the inverter. A switch network has a first switch connecting one of an AC power input line and a neutral line of the AC power input stage to the power factor corrector and a second switch selectively connecting the AC power input stage to the power factor corrector or the link capacitor. A controller operates the power factor corrector and the switch network based on a received AC input power condition.
