Abstract
The invention relates to a power semiconductor device with a substrate and an electrically conductive DC voltage bus bar system and a capacitor connected to the bus bar system, wherein the power semiconductor device has, for securing the capacitor, a capacitor securing apparatus comprising a receptacle device for receiving the capacitor, in which at least part of the capacitor is arranged. Electrically conductive bus bar system terminal elements are electrically connected thereto and run in the direction of the substrate. An elastic first deformation element is materially bonded to the capacitor securing apparatus and is formed from an elastomer is arranged on the side of the capacitor securing apparatus facing the DC voltage bus bar system. The device is embodied in such a way that the capacitor securing apparatus, via the deformation element, presses the DC voltage bus bar system in the direction of the substrate and thereby presses the bus bar system terminal elements against electrically conductive contact areas of the substrate such that the bus bar system terminal elements are electrically conductively pressure-contacted with said contact areas of the substrate.
