To minimize thermal interference between components by separating the heat dissipation paths of the pulse transformer and gate driver, and to reduce size and cost by mounting the components close together.SOLUTION: A gate driver 5 is thermally in contact with a cooler 300 via a first pattern 10 of a multilayer board 200 and a first screw 20 that secures the multilayer board 200 to the cooler 300, and the first pattern 10 is wired so that it does not overlap in plan view with a pulse transformer 8 terminals and the wiring connected to the pulse transformer 8 terminals.SELECTED DRAWING: Figure 2 【課題】パルストランスとゲートドライバの放熱経路を分離することで部品の熱干渉を最小限に抑制し、部品を直近に実装することで小型・低コスト化を図る。【解決手段】ゲートドライバ５は、多層基板２００の第一のパターン１０および多層基板２００を冷却器３００に固定する第一のねじ２０を介して冷却器３００に熱的に当接されており、第一のパターン１０はパルストランス８端子およびパルストランス８の端子に接続される配線と平面視で重ならないように配線している。【選択図】図２
