    Abstract: A power semiconductor module includes: an electrically insulative frame having opposite mounting sides and a border wall that defines a periphery of the frame; a substrate seated in the frame; power semiconductor dies attached to the substrate; signal pins attached to the substrate and electrically connected to the power semiconductor dies; a busbar attached to the substrate and extending through the border wall; a receptacle in the border wall configured to receive a current sensor module and that exposes part of the busbar, the exposed part of the busbar having an opening; and a rotation bar jutting out from a sidewall of the receptacle and onto the exposed part of the busbar without obstructing the opening in the busbar, wherein the rotation bar forms an axis of rotation within the receptacle. A power electronic assembly that incorporates the power semiconductor module and corresponding method of production are also described.

    Abstract: A system is provided with a magnetic field sensor being positioned in a magnetic field of a magnet that is coupled to a rotatable driving shaft. The magnetic field sensor is configured to sense a rotation of the magnetic field in response to a rotation of the rotatable driving shaft, and generate an angle sensor signal based on an orientation angle of the magnetic field. The angle sensor signal includes angular values that represent an absolute orientation angle of the rotatable driving shaft. The system includes a memory storing a mapping of values of a patterned signal to the angular values, electronic circuitry configured to generate, based on the angular values and the stored mapping, the patterned signal, and a signal generator circuit configured to generate a signal representing the absolute orientation angle of the rotatable driving shaft based on the angle sensor signal.
