摘要： A charging apparatus for an electric vehicle is provided. The apparatus includes an AC power input terminal receiving one AC input power from among single-phase AC power and multi-phase AC power. A power factor corrector having full bridge circuits receives the AC input power through the AC power input terminal. A link capacitor is charged through the power factor corrector. A first switch connects any one of an AC power input line and a neutral line of the AC power input terminal to the power factor corrector and a second switch selectively connects the AC power input terminal to the power factor corrector, or the link capacitor. The power factor corrector and the switch network operate based on a condition of received AC input power. The second switch includes a third switch and a fourth switch that connect each full bridge circuit to a positive battery electrode.
