Abstract:
This study presents a novel Switched Reluctance Motor (SRM) drive system with power
factor improvement. Recently, many of the converters with variable speed drives have no input power
factor correction circuits. This results in harmonic pollution of the utility supply, which should be
avoided. The effect of power factor variation in terms of harmonic content is also analyzed in this
study. The different operations like single pulse, soft chopping and hard chopping modes are done with
and without a power factor controller. This study describes the buck – boost converter topology with
above said methods for SRM drive. The boost converter is used to improve the input sinusoidal current
and the buck converter is used to regulate the dc source voltage. The proposed topologies were
simulated using MATLAB / Simulink software package and the results were obtained. The computer
simulation results support the proposed methods.
