PROBLEM TO BE SOLVED: To provide a DC-DC converter capable of achieving miniaturization while preventing generation of an excessive inrush current.SOLUTION: The DC-DC converter 10 includes switching elements SW7, SW8; a transformer L4 comprised of a winding L4a and a winding L4b; diodes D5, D6; a chalk coil L9, and a capacitor C10. The DC-DC converter 10 further includes an inrush current prevention section 3 provided on a passage in which an electric current runs through the capacitor C10 from a DC power supply 1. An impedance of the inrush current prevention section 3 is larger when turning on the DC power supply than stationary time. |
