  • Current sensor and method for sensing a strength of an electric current
    Patent number: 11500014
    Abstract: Examples relate to a current sensor and to a method for sensing a strength of an electric current using two groups of magnetic sensing probes. The current sensor includes a first group and a second group of magnetic sensing probes. The current sensor comprises sensor circuitry coupled to the first and the second group of magnetic sensing probes. The sensor circuitry is configured to determine a first differential magnetic field measurement of a magnetic field using probes of the first group of magnetic sensing probes. The sensor circuitry is configured to determine a second differential magnetic field measurement of the magnetic field using probes of the second group of magnetic sensing probes. The sensor circuitry is configured to determine a strength of the electric current based on a difference between the first differential magnetic field measurement and the second differential magnetic field measurement.
