PROBLEM TO BE SOLVED: To solve such problems of a power conversion apparatus that it is extremely important to cool the power conversion apparatus for enhancement of power conversion performance, but especially a capacitor module for DC smoothing housed in the housing of the power conversion apparatus is thermally weak, and thereby efficient cooling of the capacitor module is required to ensure performance, and that it is also required to minimize heat penetrating from the outside as much as possible.SOLUTION: A conductor plate of a capacitor module and a 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.SELECTED DRAWING: Figure 9 |
