  • Patent number: 10163761
    Abstract: A power semiconductor device comprises a substrate; and power semiconductor components disposed on and connected thereto. The device includes a housing part with a housing wall having a first cutout. The device has, for making electrical contact therewith, a unitary load connection element which passes through the first cutout in an X direction, is electrically conductive, and has an outer connection section disposed outside the housing part and an inner connection section disposed within the housing part. A first bush which has an internal thread running in the X direction is rotationally fixed and movable in the X direction in the housing wall. The first outer connection section has a second cutout aligned with the first bush. The load connection element has a first holding element disposed near the first cutout, the holding element engaging in a groove in the housing wall which runs perpendicular to the X direction.

  • Patent number: 7613008
    Abstract: A power semiconductor module is presented. The power semiconductor module includes a plurality of capacitors coupled in parallel with each other. Each of the plurality of capacitors each includes a first and a second connection element. The power semiconductor module further includes a first and a second busbar. The first connection element of each of the plurality of capacitors is bonded to the first busbar, and the second connection element of each of the plurality of capacitors is bonded to the second busbar. The power semiconductor module further includes an insulating element disposed between the first busbar and the second busbar, and a pressure assembly that includes at least one pressure body and one associated counterpart pressure body. The first connection element and the second connection element of each of the plurality of capacitors is subjected to pressure and electrically bonded to the associated busbars by the pressure assembly.

  • Patent number: 7288842
    Abstract: Introduced is a power semiconductor module preferably a disk cell with a power semiconductor element arranged in the interior of the housing. In a preferred embodiment, the disk cell has two load and at least one auxiliary connection and the auxiliary connection extends from the power semiconductor element and ends at a corresponding exterior connection element. The exterior connection element of the auxiliary connection penetrates the housing and is a pen-type metal preform in the interior.

  • Patent number: 5245067
    Abstract: A process for purifying organopolysiloxanes, which comprises treating organopolysiloxanes after their preparation with an elemental metal. Impurities which are related to the preparation of organopolysiloxanes and cause changes in color, in particular during storage under the influence of heat, subsequent clouding, inhibition of catalysts, a lack of heat stability, a lack of dielectric strength or the formation of odors, especially after exposure to light, are removed by the process of this invention.
