Abstract: During a dead time, a resonance current generated by a load current that flows in a resonance inductor and a resonance current generated by an excitation current of a transformer flow in a resonance circuit constituted by the resonance inductor and capacitors that exist in parallel to respective switching elements. A controller performs a turning off operation on the switching elements at a timing that the resonance current generated by the load current and the resonance current generated by the excitation current are cancelled each other during the dead time.
