Patents by Inventor Wolfgang Westermann

Wolfgang Westermann 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: 11942274
    Abstract: The invention relates to a film capacitor for power electronics, which comprises a first electrically conductive layer, which is arranged on a first end side face of the film capacitor, wherein the surface normal of the first electrically conductive layer is perpendicular to the surface normals of dielectric films of the film capacitor. A second electrically conductive layer is arranged on a second end side face opposite from the first end side face, wherein the surface normal of the second electrically conductive layer is perpendicular to the surface normals of the dielectric films of the film capacitor. The film capacitor has at least one inner passage, which extends from the first electrically conductive layer to the second electrically conductive layer, wherein the passage is formed by removal of capacitor material. The invention also relates to a capacitor assembly.

  • Patent number: 6043972
    Abstract: Film capacitor of a film/foil or metallized embodiment with a wound or layered structure with a cup sheath or sheath made of thermosetting plastic material with axial or radial connecting wires, in which the sheathed film capacitor, which is a finished component once all the electrical parameters have been tested, is accommodated in a second sheath, which is designed as a cup, and the connecting wires are bent around onto mutually opposite outer sides of this second cup sheath and are in each connected to a connecting metal-sheet section.

  • Patent number: 4656556
    Abstract: A plastic-film wound capacitor having a cast resin, cast-coated cup encapsulation and connecting wires which radially make contact with the wound capacitor body can be simply and economically manufactured in chip configuration. The connecting wires of the chip capacitor are bent through 180.degree. and connected, respectively, to a sheet metal section on the outside of the cup encapsulation.

  • Patent number: 4578737
    Abstract: Disclosed is a synthetic resin film wound capacitor, in particular a flat wound capacitor in a chip configuration, comprising a casing of a material that retains its shape under the effect of heat, for example a thermosetting synthetic resin, and connecting elements of a thin sheet metal attached to the ends of the capacitor such that sections of which project from the casing and are angled with respect to the frontal side of the capacitor. This synthetic resin film capacitor in a chip configuration resists thermal stresses during the overhead soldering of assembled printed circuits and therefore extends the possible applications of synthetic resin film capacitors. Also disclosed is a process for the manufacture of a capacitor according to the present invention.
