Zusammenfassung: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.
