A driving circuit for a multi-phase switched reluctance (SR) machine, wherein a reduced number of wire connections between the machine and driving circuit are needed. In addition, one embodiment of the driving circuit requires the use of fewer individual diodes for the circuit design. The reduction in the number of wire connections and diodes provides greater reliability, improved efficiency, and lower production costs.
