PROBLEM TO BE SOLVED: To solve such problems of a power converter that it is extremely important to cool the power converter for enhancement of power conversion performance, but a capacitor module for DC smoothing housed, especially in the housing of the power converter, is thermally weak, and thereby efficient cooling of the capacitor module is required to ensure the performance, and that it is also required to minimize the heat penetrating from the outside.SOLUTION: The conductor plate of a capacitor module and the housing are connected via a cooling plate, and an AC connection bus bar and the housing are also connected via the cooling plate, so as to release heat from the capacitor module and the AC connection bus bar to the housing via the cooling plate. |
