Product Description
Closed-loop Hall current sensor is also called Hall magnetic balancing current sensor. It incorporates the mentioned theory with the magnetic balancing theory. In other words, the ferromagnetic field concentrator concentrates the magnetic field generated by the primary current and applies it to the Hall component. Then the voltage signal output from the Hall component is amplified and becomes the input of the power amplifier. The offset current output flows through the secondary compensating coil.
The magnetic field generated by the secondary coil is opposite to the field generated by the primary current. In such a way, the primary field is compensated and the Hall output is reduced gradually. When the primary field is equivalent to the second one and the offset current keeps stable, it is the magnetic balancing. This circuit mainly consists of an electromagnetism conversion component, circuit amplifier and drive compensating circuit.
