A power conversion device uses a plurality of magnetically coupled coils to distribute input power in a multiple output manner in accordance with a power request from a load. When supplying power from an AC power supply (1), at least one of an AC/DC converter (2) and first to fourth switching circuits (4, 8, 13, 30) controls the voltage at the output side of the AC/DC converter (2) according to the deviation of the detected value of the voltage from the target value of the voltage. When supplying power from a first DC voltage source (11) or a second DC voltage source (34), the second switching circuit (8) between the first DC voltage source (11) and a transformer (6) or the fourth switching circuit (30) between the second DC voltage source (34) and the transformer (6) supplies the power according to an arbitrary time ratio. |
