Zusammenfassung:	PURPOSE: A power conversion device and a control method thereof are provided to improve the power conversion efficiency of a fuel battery power conversion device by reducing a loss which is generated when power from a fuel battery is converted into power which is required for home. CONSTITUTION: A push-pull converter(110) comprises a first switching element(S1) and a second switching element(S2). A high frequency transformer(120) diversifies an AC voltage which is outputted from the push-pull converter. A doubler rectifier(130) reduces the transformation ratio of the high frequency transformer. A DC link module(140) comprises leakage inductance(L) and a high frequency capacitor(C). A DC/AC inverter(200) supplies a DC voltage which is outputted from the DC link module to a system after converting the DC voltage into an AC voltage.
