Abstract: Switched Reluctance Motor SRM the doubly salient singly newlineexcited motor has a simple and robust construction Although the induction newlinemotor is still the workhorse of the industries the promising feature of the high newlinetorque to mass ratio high torque to inertia ratio low maintenance high newlinespecific output and the excellent overall performance of SRM makes it an newlineefficient competitor for AC drives newlineDirect Torque Control DTC has many promising features and newlineadvantages such as absence of speed and position sensors absence of newlinecoordinate transformation reduced number of controllers and minimal torque newlineresponse time In addition there are many limitations that need to be newlineinvestigated A major concern in direct torque control of SRM drives is torque newlineand flux ripples since none of the switching vectors is able to generate the newlineexact stator voltage required to produce the desired changes in torque and newlineflux So the reduction of torque and flux ripples is the major role in this newlinework The objective of the work is to minimize the torque ripple in direct newlinetorque control of switched reluctance motor drive using multiple voltage newlinespace vectors In this thesis two methodologies have been introduced to newlineincrease the voltage space vectors One is by increasing the number of phases newlineof SRM Multi phase SRM and other is implementation of Discrete Space newlineVector Modulation DSVM techniques newline newline
