ABSTRACT:
A reluctance machine system including a reluctance machine having a rotor and a stator including at least one phase winding and a full pitch auxiliary field winding where constant currents are established in the auxiliary field winding to assist in the establishment of a magnetic field in the machine so as to improve the machine's performance. A novel power converter uses residual energy remaining in the phase windings at the time the phase winding is de-energized (turned-off) to provide the constant energy for the auxiliary field winding.
