PROBLEM TO BE SOLVED: To reduce the power loss of a series resonance converter circuit. SOLUTION: The series resonance converter circuit includes an inverter circuit that includes at least a pair of first and second switching elements connected between DC input terminals; a transformer including a primary winding and a secondary winding connected to the inverter circuit; and a resonance inductance means connected in series to the primary winding or the secondary winding for the transformer. The series resonance converter circuit, further, includes a primary-side resonance capacitor connected in series with the resonance inductance means through the first or second switching means, first and second secondary-side resonance capacitors mutually connected in series between DC output terminals, and first and second unidirectional elements mutually connected in series between the DC output terminals. The series resonance converter circuit, further, includes the resonance inductance means for resonating in series, in cooperation with the resonance capacitance by the primary-side capacitor and the first and second secondary-side resonance capacitors.
