Abstract
A current sensor for sensing a current through two different conductors. The sensor comprises a magnetic sensor configured to read a magnetic field induced by the first and second currents. The sensor is configured also to provide a first signal representative of a magnetic field parameter in a first direction and configured to provide at least a second signal representative of a magnetic field parameter in a second direction different from the first direction.
Claims14
A current sensor for sensing a first current through a first conductor and for sensing a second current through at least a second conductor different from the first, the sensor comprising:
- a magnetic sensor configured to provide a first signal representative of a magnetic field parameter in a first direction and configured to provide at least a second signal representative of a magnetic field parameter in a second direction different from the first direction, the magnetic field being induced by the first and the second currents,
- a processing unit programmed for deriving a first output signal and a second output signal based on weighted combinations of the first signal and the at least second signal from the magnetic sensor, wherein the weights of the weighted combination are chosen such that the first output signal is indicative of the first current and the second output signal is indicative of the second current,
- wherein the magnetic sensor and the processing unit are provided in a single sensor package.
