1. A charger capable of bidirectional power transfer, comprising:
a power factor compensation circuit configured to convert a multi-phase AC voltage into a DC voltage and comprising a plurality of inductors and a plurality of switching elements;
a DC link capacitor to which the DC voltage converted by the power factor compensation circuit is applied;
a bidirectional DC converter configured to bidirectionally convert a magnitude of a voltage between the DC link capacitor and a battery; and
a controller configured to: in a DC power supply mode, control 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 control 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.
