Performance Comparison of Cuk and M-Cuk Converter on SRM Drive System

Abstract: Power factor correction is a method to increase the power factor of the supply and in turn improve the overall power quality of the ac mains supply. Here the control of Switched Reluctance Motor is developed with a power factor correction converter. It utilizes two modified Cuk converter fed Switched Reluctance Motor (SRM) drive to improve the power quality. Cuk converters operates separately for two half cycles of supply voltage. Converter is made to operate in discontinuous conduction mode. The power factor correction converter provides a regulated dc input which in turn is used to control the speed of motor. The design is based mostly for low voltage household applications. Comparative performance analysis is done based on MATLAB results.
