PROBLEM TO BE SOLVED: To facilitate cooling of an inverter device having a plurality of inverters and used for series hybrid system, and the like.SOLUTION: Switching elements 21-23, 31-33 of first and second inverters 14, 16 are attached to two symmetric surfaces of an inverter case 41, becoming a cooling channel for distributing the cooling water, in contact therewith. A capacitor 15 is housed in the cooling channel, as a capacitor shared by the first and second inverters. Consequently, a plurality of inverters can be housed in one housing, and the shape can be made compact while enhancing the cooling efficiency. |
