The closed-loop Hall current sensor is also called zero-flux transformer or magnetic balance current sensor. The magnetic field generated by the primary current Ip in the magnetic core is compensated by the magnetic field generated by the secondary compensation coil current, so that the Hall device is in the To detect the working state of zero magnetic flux, the compensation current Is reflects the primary current Ip in proportion. The specific working process is: when a current passes through the main circuit, the magnetic field generated on the wire is gathered by the magnetic core and induced to the Hall device, and the generated signal output is used to drive the power tube and make it conduct, thereby obtaining a compensation Current Is. This current passes through the multi-turn winding to generate a magnetic field, which is exactly opposite to the magnetic field generated by the measured current, thus compensating the original magnetic field and gradually reducing the output of the Hall device. When the magnetic field generated by multiplying Ip and the number of turns is equal, Is will no longer increase. At this time, the Hall device plays the role of indicating zero magnetic flux. At this time, Ip can be tested by Is. When Ip changes, the balance is destroyed, and the Hall device has a signal output, that is, the above process is repeated to achieve balance again. Any change in the measured current will upset this balance. Once the magnetic field is out of balance, the Hall device has a signal output. After the power is amplified, a corresponding current flows through the secondary winding immediately to compensate the unbalanced magnetic field. From the magnetic field imbalance to the balance again, the time required is theoretically less than 1μs, which is a dynamic balance process.
