Abstract: In a DC-DC converter, the cooling of switching elements has been performed only by means of a cooling plate; therefore, there is a problem in that, to effectively radiate heats generated by power MOSFETs that have large heating values and that are arranged parallel, it becomes necessary to reduce thermal resistances and complicate the cooling route of a water-cooling device. Plural switching elements for controlling currents flowing through inductor elements, which are used for voltage conversion of a DC-DC converter, are fixed to a metal case via a heat conductive insulating material and via a metal radiator having a better heat conduction characteristic than the metal case. Because there occur no large mixing phenomena of heat currents among neighboring switching elements, and there are only little heat interferences between the neighboring switching elements, the thermal diffusion characteristic is improved, and the cooling efficiency for the switching elements can be increased.
