Closed-loop Type Principle Of Hall Current Sensor Based On The Magnetic Balanced Hall
- Sep 27, 2018 -

Closed-loop type principle of hall current sensor based on the magnetic balanced hall, and the closed-loop principle, when the original edge of current IP magnetic all high quality core focus in magnetic circuit, the hall element fixed detection in the air gap magnetic flux, by means of the number of turns around the magnetic core coil output reverse compensation current, flux produced by the IP used to offset the original edge, resulted in the zero flux always stay in the magnetic circuit. After the processing of special circuit, the output of the sensor can accurately reflect the current change of the original side.
