Abstract
A power conversion device that distributes input power to multiple outputs in accordance with power requirement of a load, using a plurality of magnetically coupled windings. In the case of supplying power from an AC power supply, at least one of an AC/DC converter and first to fourth switching circuits controls voltage on an output side of the AC/DC converter, based on a deviation between a detected value and a target value of the voltage. In the case of supplying power from a first DC voltage source or a second DC voltage source, the second switching circuit or the fourth switching circuit provided between the first DC voltage source or the second DC voltage source and the transformer supplies power based on an arbitrary time ratio.
