Abstract
A resonance power conversion device includes a bridge circuit, a transformer, a current detection circuit, and a control circuit. The bridge circuit includes a plurality of switching elements and receives a DC power. The transformer is connected to an output side of the bridge circuit. The current detection circuit detects a value of a current flowing through at least one of the plurality of switching elements. The control circuit determines whether or not an abnormality is occurring in the resonance power conversion device, based on the value detected by the current detection circuit at a predetermined time during a switching control.
