Abstract:
1. A current sensor, comprising: a conductive element with at least three separate terminal areas, a common conductive area and at least three separate intermediate areas connecting the at least three separate terminal areas to the common conductive area, wherein each of the at least three separate terminal areas is connected separately via a respective separate intermediate area of the at least three separate intermediate areas to the common conductive area to guide separately a current applied to the respective terminal area into the common conductive area; and at least two magnetic field sensors arranged at different geometric positions adjacent to the at least three separate intermediate areas, wherein each of the at least two magnetic field sensors is configured to sense a magnetic field component of the current flowing into the common conductive area to provide a sensor signal based on the sensed magnetic field component; wherein the at least two magnetic field sensors are arranged adjacent to the at least three separate intermediate areas such that the current sensor can measure separately the currents guided by the at least three separate terminal areas via the at least three separate intermediate areas into the common conductive area; and wherein a geometric area surrounding and abutting the common conductive area is divided into two geometric sectors, each of the two geometric sectors abutting the common conductive area, wherein the at least three terminal areas are arranged in a first geometric sector of the two geometric sectors, and wherein signal and supply terminals of the at least two magnetic field sensors are arranged in a second geometric sector of the two geometric sectors.
