Abstract
A charging apparatus for an electric vehicle has a small-sized simple structure, and charges a battery of the electric vehicle upon receiving electricity from various kinds of power sources. The charging apparatus includes a motor, an inverter, an AC power input stage, a power factor, a link capacitor, a switch network, and a controller. The AC power input stage receives an AC input power from a single-phase AC power or a multi-phase AC power. The power factor corrector has a single three-leg half bridge circuit receiving the AC input power through the AC power input stage, and the link capacitor is charged through at least one of combinations of the power factor corrector, the motor, and the inverter. The controller controls the power factor corrector and the switch network based on a condition of AC input power received through the AC power input stage.
