Abstract
Between a direct-current power source and a connection point where a resonance current flowing in an opposite direction from a main current joins the main current from the direct-current power source in a resonant converter, there is provided a current blocking circuit which blocks the resonance current toward the direct-current power source. In consequence, it is possible to prevent the reverse charging of the direct-current power source with the resonance current which realizes soft switching in the resonant converter.
