PROBLEM TO BE SOLVED: To provide a resonant converter controlling output voltage by controlling a switching frequency of a switch element connected to a series circuit where a primary winding of a transformer, an inductor and a capacitor are connected in series in the case of a light load and no-load. SOLUTION: The resonant converter 1 includes the transformer T, the switch elements Q1 to Q4 constituting a full bridge circuit arranged on a primary-side of the transformer T, and the inductor Lr and capacitors Cr and Cx, which are connected in series to the primary winding T1 of the transformer T. The capacitor Cx is connected in parallel to the series circuit where the primary winding T1 of the transformer T, the inductor Lr and the capacitor Cr are connected in series.
