The Hall effect is that when a conductor carries current through a magnetic field, a voltage difference is generated on the side of the conductor. By measuring the voltage difference, the current value measured by the sensor can be known;

[0025] The Hall current sensor is based on the magnetic balance Hall principle. Current is passed through the control current end of the Hall element, and a magnetic field with a magnetic induction intensity of B is applied in the normal direction of the Hall element plane, generating an electric potential VH perpendicular to the current and magnetic field. This electric potential is proportional to the product of the control current and the magnetic induction intensity. It is a mature prior art product and is widely used in various power systems.
