Abstract
A current controller for a switched reluctance machine is disclosed. The current controller controls the switching frequency of the power devices that control the energization of the phase windings of the machine and the peak magnitude of the phase current in response to a single pulse width modulated signal. Also disclosed is a method and circuit for implementing slope compensation in a current controller for a switched reluctance machine where the magnitude of the slope compensation is proportional to the voltage of the power supply from which the phase windings are energized.
