Abstract
Disclosed herein is a charging apparatus. The charging apparatus includes an alternating current (AC) power input stage receiving at least one AC input power from among a single-phase AC power and a multi-phase AC power. A power factor corrector has a single three-leg half bridge circuit receiving the at least one AC input power through the AC power input stage. A link capacitor is charged through the power factor corrector. A converter connects between the link capacitor and a battery. A first switch connects any one of an AC power input line and a neutral line of the AC power input stage to the power factor corrector. A second switch selectively connects 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 condition of the at least one AC input power.
