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.

[ I claim as my invention:] [1.] A power converter for a switched reluctance machine having at least one phase winding and a full-pitched auxiliary field winding, the power converter comprising:a DC bus; anda switch having a first position and a second position, the switch being coupled to the phase winding and to the DC bus in such a manner that when the switch is in the first position the DC bus provides phase energization current to the phase winding; and when the switch is in the second position the phase winding current dissipates through the full-pitched auxiliary field winding to provide energization current to the full-pitched auxiliary field winding.
