  • Patent number: 9596782
    Abstract: In a power converter, cooling of the power converter is extremely important for improving a power conversion performance. Specifically, a DC smoothing capacitor module stored in a housing of the power converter is heat-sensitive, and in order to secure the performance, efficient cooling of the capacitor module is required. In addition, reducing the heat entering from the outside as much as possible is required. A conductor panel of the capacitor module and the housing are connected via a cooling panel, an AC connection bus bar and the housing is connected by the cooling panel to release heat from the capacitor module and the AC connection bus bar to the housing via the cooling panel.
