The present invention relates to a bidirectional converter and a control method thereof. A power supply device according to one embodiment of the present invention includes a low voltage direct current-direct current converter (LDC) which converts the voltage of a high voltage battery to supply power, a first low voltage battery which receives power from the LDC and is charged and supplies power to a general load, a bidirectional converter which converts the voltage supplied from the LDC and controls the charge amount of a second low voltage battery, a second low voltage battery which receives power from the bidirectional converter and is charged and supplies power to a dual power load, a first relay disposed between the LDC and the first low voltage battery, a second relay disposed between the bidirectional converter and the second low voltage battery, a first battery sensor which measures the voltage of the first low voltage battery, a second battery sensor which measures the voltage of the second low voltage battery, and a control unit which controls the bidirectional converter.
