Potential isolated current measurement circuit

Published:2011/6/30 20:00:00 Author:TaoXi | Keyword: Potential, isolated, current measurement | From:SeekIC

This circuit sensitive component is connected into the magnetic susceptibility component of the differential circuit. By changing the taps of winding n1 and winding n2, you can change the measuring range of the measuring current. The two sensitive components B are connected in the bridge type circuit, the output of the bridge type circuit controls the differential input port of the operational amplifier. Figure (c) shows the relation curve between the measuring current and the measurement error meter indicating current IA.
