PROBLEM TO BE SOLVED: To obtain an insulation type DC/DC converter capable of securing vibration resistance of a printed board while achieving miniaturization (power density improvement) of the insulation type DC/DC converter.SOLUTION: The insulation type DC/DC converter is constituted of: a base on which main components having minimum component constitution composed of a switching element, a transformer, a rectifier element, a smoothing coil, and a smoothing capacitor are mounted; and a printed board on which at least either one of main circuit wiring for connecting the switching element to a primary winding of the transformer and drive signal wiring for driving the switching element is mounted. In the insulation type DC/DC converter, a metallic case is arranged between the base on which the main components are mounted and the printed board, and the printed board is fixed by bosses formed on the metallic case.SELECTED DRAWING: Figure 2 |
