<p>PROBLEM TO BE SOLVED: To provide a power conversion apparatus using a small, high capacity, and highly reliable film capacitor, which prevents creation of a gap between films of the film capacitor in a case where a film capacitor element with a large ellipticity is applied in the power conversion apparatus.SOLUTION: In a power conversion apparatus, a housing with a plurality of chambers formed therein accommodates a power semiconductor module, which converts between DC and AC, in the first chamber, and accommodates a wound type flat film capacitor, which makes DC voltage smooth, in the second chamber. The power semiconductor module and the film capacitor are electrically connected by a conductor plate. The conductor plate is fixed to the housing. The flat film capacitor is installed on a seat member in the second chamber with its flat faces facing upward and downward. The upper flat face abuts on the conductor plate, and the conductor plate is fixed to the housing. Thereby the conductor plate is pressed and fixed between the conductor plate and the seat member.</p> |
