Torque ripples reduction for SRM drive using SVM-based converter

Abstract

An early electric machine, the switching reluctance motor (SRM) is old. Low production cost, durability, and streamlined design make it perfect for industrial use. The design's excessive torque ripple, noise, and control issues negate these benefits. This work minimizes torque-ripple in switching reluctance motor (SRM) drives using a torque-sharing function (TSF). The suggested method converts reference torque into a reference current waveform using an analytical formula. Torque ripple is a major shortcoming of the Switched Reluctance Motor. We start by looking at torque ripple from the basic space voltage vector, which is based on direct torque control theory. A unique torque ripple-reducing voltage vector was proposed after the analysis. We use space vector modulation to power SRMs. The SRM is powered by three asymmetrical three-phase power converter legs with two IGBTs and two free-wheeling diodes.
