Abstract: A control for operating an inverter coupled to a switched reluctance machine includes a relative angle estimation circuit for estimating rotor angle for a phase in the switched reluctance machine. The relative angle estimation circuit estimates a phase voltage and thereby calculates phase flux linkage to estimate the rotor angle.

Abstract: A sensorless control for operating an inverter coupled to a switched reluctance machine includes an instantaneous position generation circuit that develops a signal for controlling commutation of the switched reluctance machine. The instantaneous position generation circuit includes a digitally controlled counter which provides a direct interface between a position estimation circuit and commutation logic for the inverter.
