Abstract
A circuit for controlling current flow to an associated inductive load is provided. The circuit includes a switching element having an open state and a closed state that intermittently connects an associated power supply to the inductive load when the switching element is in the closed state, a switch driver that generates a switch drive signal provided to a control element of the switch that controls the state of the switch to be the open state or the close state based on a desired load current set point and a feedback signal, a current sensor that measures a current flowing through the switching element and the load and generates a sensed current signal, and a summing circuit that adds a representation of the sensed current signal and a supplemental signal comprising a representation of the switch drive signal to generate the feedback signal.
