The present invention relates to a bidirectional on-board charger and a method of controlling the same. The bidirectional on-board charger according to the present invention includes: an input power source which is a power source of a charging control system; a power factor corrector (PFC) which is connected to the input power source; a DC/DC circuit which is connected to the power factor corrector and includes a switching unit and an output terminal; a first switch which is On/Off controlled to connect any one of a first line for connecting the input power source and the power factor corrector and a second line for connecting the power factor corrector and an output terminal of the DC/DC circuit; and a second switch which is disposed between the switching unit and the output terminal of the DC/DC circuit and On/Off controlled. According to the present invention, there is an advantage in that a bidirectional power transfer is enabled only by adding the two switches to an OBC circuit in the related art.
