    摘要: A power module is provided that is configured to supply power to a load. The power module includes a current generator configured to generate a current; a current rail configured to receive the current and output the current from the power module, wherein the current rail includes a first opening formed therethrough, and the current, while flowing along the current rail in an output direction, flows around the first opening; and a housing that houses the current generator, wherein the housing includes an outer frame from which the current rail outwardly extends, wherein the outer frame includes a recess aligned with the first opening of the current rail such that the recess and the first opening form a unitary opening.

    摘要: Rotational angle sensor systems and methods are provided for detecting an angular position of a movable structure. A system may include a movable structure, a rotating member, a magnet and an angular sensor. The movable structure may be configured to rotate about an axis of rotation between a first rotational position and a second rotational position. A rotating member may be coupled to the movable structure and configured to rotate about the axis of rotation based on movement of the movable structure such that rotational positions of the rotating member and the movable structure correspond to one another. A magnet may have a magnetic field pattern with a magnetic field orientation and an angle sensor may be configured to detect the magnetic field pattern and generate one or more signals, based on the magnetic field orientation, corresponding to the rotational position of the movable structure.

    摘要: 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.

    摘要: A method may include pressing a sensor module onto a control board such that the sensor module is at an initial position where an air gap is present between a module body of the sensor module and the control board such that compliant pins of the sensor module are partially inserted into the control board. The method may include mounting the control board on a power module to cause pins of the power module to be at least partially inserted into the control board and the sensor module to be at least partially inserted in the power module such that a protrusion is through an opening in a busbar. The method may include pressing the control board onto the power module to cause the pins of the power module to be further inserted into the control board, the sensor module to be further inserted in the power module, and the sensor module to be at a final position.
