PROBLEM TO BE SOLVED: To provide a DC-DC converter capable of achieving high efficiency and miniaturization of the device while suppressing generation of surge due to an adverse effect of a recovery current.SOLUTION: A secondary side of a DC-DC converter (10) includes a secondary side reflux circuit (18) having a series circuit which is formed by connecting a secondary side reflow diode (181) in series to a reflow reactor (182) and reflows a load current running through a load (30) by bypassing the load current for a period for which a voltage of a DC power supply (20) is not applied to a primary side (13a) of a transformer (13a).SELECTED DRAWING: Figure 1 |
