Abstract: A galvanically isolated error amplifier using Hall effect principles for application in control circuitry. Input currents to be compared are conducted through respective windings around a gapped ferrite toroidal core. A standard Hall effect magnetic field sensor/amplifier positioned in the gap provides a voltage signal proportional to the difference in the current inputs.
