Abstract
Torque output of switched reluctance machines (SRMs) can be increased by operating with high demagnetization voltage, especially for high speeds. This is first illustrated using computed results obtained from dynamic simulation. A power converter with the capability of providing increased demagnetization voltage is then presented. The converter operation is analyzed, ratings of various components are derived, and a controller for regulating the additional demagnetization voltage is designed. Experimental results illustrate expected operation of the converter, and improved performance of the overall SRM drive in terms of increased torque and power output.
