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 power module is provided that is configured to supply power to a load. The power module includes a current generator, a current rail, and a magnetic sensor. The current generator is configured to generate a current. The current rail is configured to receive the current and output the current from the power module. The current rail includes a first opening formed therethrough, and the current, while flowing along the current rail in an output direction, produces a magnetic field. The magnetic sensor is disposed in the first opening of the current rail, and is configured to generate a differential sensor signal based on the magnetic field impinging thereon. The current generator is further configured to regulate the current based on the differential sensor signal.

Abstract: 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.
