Abstract
A circuit for use with a transformer having a plurality of windings monitors the direct current flow through a first winding and provides a corresponding compensation current to a second winding. The circuit also provides an output signal indicating whether the magnitude of the compensation current is greater than or less than a predetermined magnitude.
