Abstract
In a power conversion device, a voltage at an input/output terminal of a primary-side circuit is divided by a first capacitor and a second capacitor, and a center tap provided to the primary winding of a transformer is connected to a node between the first capacitor and the second capacitor. With this, an intermediate voltage can be output. Further, transmission power can be controlled under a state where a voltage at the first capacitor and a voltage at the second capacitor are balanced, through adjustment of switching phases of a first full bridge circuit that is the primary-side circuit and a second full bridge circuit that is a secondary-side circuit.
