Abstract
A charging apparatus for an electric vehicle is provided. The apparatus charges a vehicle battery upon receiving power from different power sources. The apparatus includes a motor generating power to drive the electric vehicle and an inverter supplying power to the motor. An AC power input terminal receives at least one of single-phase AC power and multi-phase AC power. A power factor corrector having a single three-leg half bridge circuit receives the AC input power through the AC power input terminal. A link capacitor is charged through a combination of the power factor corrector, the motor, and the inverter. A switch network has at least one switch for selectively connecting the AC power input terminal to the power factor corrector, the link capacitor, the motor, or the inverter. A controller operates the power factor corrector, the switch network, and the inverter based on a condition of received AC input power.
