Abstract
Five inverter power circuits suitable for switched reluctance motor (SRM) drives are analyzed. The peak voltage and current ratings of the power switches and the size and peak ratings of the DC link components of each circuit are compared. As an example, a converter analysis and selection are performed for a high-speed, 6/2 SRM, suitable for a spindle drive, and a high-torque, 8/6 motor. Experimental results obtained for a high-torque drive are presented. Of the five circuits, only two are found suitable for industrial SRM drives, supplied from 380 or 460 V AC lines. The remaining circuits all use dual rail topology, requiring that the inverter active devices have a rating at least twice the motor supply voltage. A discussion of basic motor requirements is included.ETX
