  • Publication number: 20240110940
    Abstract: A power connector is provided that is configured to conduct a current. The power connector includes a base structure, an extension structure, and a connector head structure that define a current path for the current. The extension structure is coupled to and extends between the base structure and the connector head structure. The connector head structure includes a bore-hole that vertically extends into the connector head structure toward the base structure. The bore-hole is configured to receive a fastener for coupling the power connector to an electrical interface of a device. The connector head structure has a mechanical engagement feature configured to mechanically engage with a torque stabilization tool during a fastening of the fastener to the connector head structure in order to prevent a torque applied by the fastening of the fastener from being transferred to the extension structure.

  • Patent number: 11796571
    Abstract: A busbar for current transport comprises conductive material, which extends along a current direction. A recess for a magnetic field sensor extends into the conductive material, a middle of the recess being shifted by a predetermined distance from a middle of the conductive material in the direction of an edge of the conductive material, so that, within a frequency range, a frequency dependency of a magnetic field, which is induced by an alternating current flowing along the current direction, is reduced in comparison with a busbar having a central recess.

    Abstract: A semiconductor module includes a semiconductor die, an encapsulation encapsulating the die, and first and second power contacts electrically coupled to the die. The power contacts each include an external part exposed from the encapsulation and an overlapping part. The power contacts are configured to carry respective first and second currents. A current flow of the first current in the external part of the first power contact points into or out of the semiconductor module. A current flow of the second current in the external part of the second power contact points in the opposite direction of the first current flow. The overlapping parts overlap such that the current flows point in the same direction in the overlapping parts. The overlapping parts include overlapping slots configured to accept a current sensor element for measuring a combined current in the overlapping parts.
