Abstract

The invention is a circuit (60) for controlling the operation of a variable reluctance machine having a plurality of phase windings. Pairs of phase windings (64, 66 or 65, 67) are controlled by a switching circuit having only three power switches which are controlled by a switch controller. Pairs of phase windings may be switched by one or more sets of switches each having the three power switches in several different modes of operation. The invention may be used to control multiple phase machines with an odd number of phases.
