Title: Current sensing system

Abstract: A circuit for sensing the current applied to a load in power supplies, inverters, and other power conversion equipment and similar systems wherein the voltage between the center tap of the transformer secondary winding and the junction of two resistors connected across the secondary winding in series is sensed. The control circuit for the electronic system adjusts the overall system operation to obtain the desired volt-ampere output in response to this voltage level.
