Abstract
An electric power conversion device includes a transformer composed of three or more windings magnetically coupled with each other, wherein power supply sources, are connected to at least two windings, via switching circuits, a load is connected to at least one winding, and a control circuit temporally divides, within one switching period, a total ON time during which power is supplied, in accordance with the number of the power supply sources, to supply power, the one switching period being the minimum repetitive unit during which power is supplied alternately. The control circuit allocates the divided ON times to the respective switching circuits, and the switching circuits, supply power from the power supply sources, to the load side during the allocated ON times, respectively.
