ABSTRACT:
A doubly-fed switched reluctance machine in which at least two sets of phase winding are energized to produce desired output torque is disclosed. Also disclosed are dual and single power converters for energizing the doubly-fed machine as well as exemplary excitation schemes position. Sensorless techniques and systems for controlling the doubly-fed machine, and other machines having fully-pitched or fractional-pitched windings, are also disclosed.
