According to an embodiment of the present invention, provided is an integrated converter device which can reduce weight, volume, and cost. The integrated converter device comprises: a high voltage charging unit including a power efficiency calibration part which converts an alternating current (AC) voltage of a commercial power source into a direct current (DC) voltage and compensates for low-frequency ripple, and a first switching module which converts the DC voltage outputted from the power efficiency calibration part into the AC voltage, and charging a high voltage battery using the commercial power source; and a low voltage charging unit connected between the power efficiency calibration part and the first switching module and charging a low voltage battery using the commercial power source or the high voltage battery.
