POWER FACTOR IMPROVEMENT IN SWITCHED RELUCTANCE MOTOR DRIVE USING PWM CONVERTER

This paper present the power factor improvement technique in the midpoint converter based Switched Reluctance Motor (SRM) drive using a AC-DC three level Pulse Width Modulation (PWM) converter. A conventional SRM drive produces very high level of harmonics content and poor power factor at ac mains. The proposed converter with midpoint converter fed SRM drive improves the power factor at ac mains with low current harmonics. The SRM drive with converter is modeled and its performance is simulated in Matlab/Simulink environment.
