Abstract:
Embodiments of the invention provide a current sensor including a conductive element and at least two magnetic field sensors. The conductive element includes at least three terminal areas and a common conductive area, wherein each of the at least three terminal areas is connected to the common conductive area to guide a current applied to the respective terminal area into the common conductive area. The at least two magnetic field sensors are arranged at different geometric positions adjacent to the common conductive area, wherein each of the at least two magnetic field sensors is configured to sense a magnetic field component of each current flowing into the common conductive area to provide a sensor signal based on the sensed magnetic field component.
