Patents by Inventor Stefan Hentschel

Stefan Hentschel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8599556
    Abstract: A power converter module with a liquid-cooled heat sink, a busbar arrangement having at least two busbars, at least two power semiconductor modules, which are mechanically connected to the liquid-cooled heat sink for thermal conduction and are electrically connected to connections of the power converter module by the busbar arrangement has at least one coolant line forming a single structural unit with the busbar arrangement. The coolant line prevents additional power loss in the laminated busbar.
    Type: Grant
    Filed: September 29, 2009
    Date of Patent: December 3, 2013
    Assignee: Siemens Aktiengesellschaft

  • Patent number: 8432694
    Abstract: A power converter module includes at least two power semiconductor modules, which are mechanically connected to a liquid-cooled heat sink and electrically connected to terminals of the power converter module by a busbar arrangement having at least two busbars. The busbars are insulated from one another by an insulation layer. The insulation layer is composed of two insulating layers, which are materially connected with one another so as to form therebetween a cavity having a predetermined shape and an entrance side and an exit side disposed on least one side face of the insulation layer. A connector is provided on the entrance side and the exit side and fluidly connected to the liquid-cooled heat sink. The rectifier module is thus able to sustain relatively high electrical loads compared to conventional rectifier modules, while maintaining a permitted temperature for the insulation layer and the lamination material of the busbar.
