COMPARATIVE STUDY OF DIFFERENT TYPES OF CONVERTERS FOR SWITCHED RELUCTANCE MOTOR DRIVE

Abstract

Switched Reluctance Motor (SRM) is a competition for many applications of electric drive system due to its simple
construction and robustness. This paper presents a comparison between different types of conventional converters with a new
Bridgeless SEPIC converter. The conventional converter topologies employed for SRM drive are R-dump, C- dump, H-bridge,
series and parallel type converters. The SRM with 6/4 pole is analyzed with a Bridgeless SEPIC converter by using
Matlab/Simulink packages and operating principles of various converters also described. This paper provides the results of
Bridgeless SEPIC converter yields reduced current, torque ripples with a constant speed used in medical application particularly
for Sleep Apnea Treatment.
