Summary:PROBLEM TO BE SOLVED: To achieve suppression of electromagnetic noise by enhancing output controllability while suppressing an increase in the number of components.SOLUTION: The resonance type DC-DC converter 20 includes L1 and L2 as a primary coil of a transformer 22. The primary coil L1 is connected with a secondary coil L3 in a positive-phase manner and the secondary coil L2 is connected with the secondary coil L3 in a reverse-phase manner. By setting a phase difference between two phases at 180 degrees, a harmonic component is canceled to suppress electromagnetic noise. By shifting the phase difference from 180 degrees, an output is controlled. The transformer 22 has a three-leg structure and the L1 and L2 are formed into external two legs of the three legs.
