A variable speed drive using a switched-reluctance motor permits a simpler and cheaper inverter than a PWM inverter for an induction motor. The various inverter circuit options are considered for singlewinding and bifilar-wound motors, noting the advantages of the bifilar 4-phase arrangement from the inverter's viewpoint. The inverter design process for a traction drive with a 3:1 constant power range is explained, followed by the calculation of main and commutation component ratings. Experimental results are given for chopping and for two single-pulse speeds. The control electronics are briefly described.
