Abstract
A switching circuit for a reluctance machine includes one or more half-bridge converter modules including serially connected switches connected between power rails +V.sub.dc and -V.sub.dc. A pair of capacitors are also connected between the power rails, and the phase winding of the machine is connected at one end between transistors and at the other end between the capacitors. The switches act as separate power circuits, alternately conducting to excite the phase winding either during alternate phase conduction periods or during alternate groups of phase periods. The half-bridge modules are commercially readily available as cost-effective preassembled items.
