  • Patent number: 9627343
    Abstract: A power semiconductor module and an arrangement including it. The module includes a housing, a switching device having a substrate connected to the housing, a connecting device, load connection devices and a pressure device movable relative to the housing. The substrate has a first central passage and conductor tracks which are electrically insulated from one another. A power semiconductor component sits on a conductor track. The connecting device has two main surfaces and an electrically conductive film. The pressure device has a pressure body with a second passage, in alignment with the first passage and a first recess. A pressure element projects out of the recess, and presses onto a section of the second main surface. This section is within the surface of the component projects normal to the substrate. The first and second passages receive a fastener which force-fittingly fastens the module to the cooling device.
