Abstract

The switched reluctance machine (SRM) is used for many application of electric drive system due to its simple construction and its robustness. Due to doubly salient structure of SRM; the torque pulsations are high when compared to other sinusoidal machines. The major drawback of using SRM drive is torque pulsations and increased components in the converter. In order to avoid these drawbacks a new bridgeless Single Ended Primary Inductor Converter (SEPIC) for closed loop control of SRM drive is proposed. The proposed converter reduces a conduction loss, input current ripple, torque ripples and also the Total Harmonic Distortion (THD). The requirements of converter for switched reluctance motor drives and the proposed new converter are analyzed and discussed. In this paper a new converter topology for speed control of a switched reluctance motor is proposed and verified through MATLAB simulation.
