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： A motor drive circuit provides a drive signal to an electronically commutated motor. A control circuit the motor drive circuit based on calibration data. The calibration data indicate a relationship between an actual angular position of a rotor of the motor in response to the drive signal and an expected angular position of a rotor of an ideal motor in response to the drive signal.

摘要： A semiconductor module includes a semiconductor die, a mold compound encasing the semiconductor die, a plurality of terminals electrically connected to the semiconductor die and protruding out of the mold compound, wherein a first one of the terminals has a constricted region covered by the mold compound, wherein the mold compound has a recess or an opening near the constricted region of the first terminal, and a coreless magnetic field sensor disposed in the recess or the opening of the mold compound and isolated from the first terminal by the mold compound. The coreless magnetic sensor is configured to generate a signal in response to a magnetic field produced by current flowing in the constricted region of the first terminal. The magnitude of the signal is proportional to the amount of current flowing in the constricted region of the first terminal. A method of manufacturing the module also is described.

摘要： 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.

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.
