Abstract
A power converter includes a transformer disposed between an input circuit and an output circuit. The transformer has primary and secondary windings coupled to the input and output circuit, respectively. Current passing through the input circuit is sensed and fed to a RC (Resistance-Capacitance) circuit which generates a signal proportional in magnitude to the output current sourcing out of the output circuit.
