Abstract
Disclosed herein is a charger capable of bidirectional power transfer. A power factor compensation circuit converts a multi-phase AC voltage into a DC voltage and includes a plurality of inductors and a plurality of switching elements. The DC voltage converted by the power factor compensation circuit is applied to a DC link capacitor. A bidirectional DC converter bidirectionally converts the magnitude of a voltage between the DC link capacitor and a battery. In DC power supply mode, a controller controls the bidirectional DC converter to convert a magnitude of a voltage of the battery to apply the voltage of the battery to the DC link capacitor and controls the plurality of switching elements to generate a DC supply voltage by converting the magnitude of the DC voltage of the DC link capacitor and output the DC supply voltage through a terminal through which the multi-phase AC voltage is input.
