This approached offers a great control mechanism with simple and easy circuit configuration. Switched Reluctance Motor (SRM) is one of the most recent apparatus which draws a great number of researchers’ interests. Previously several attempts are made to use the power converters as driver for SRM such as Voltage Source Inverter (VSI) and bridge converters. This paper presents an analysis study of three level inverter to control the SRM. The inverter is controlled using space vector modulation SVM. The aim of this paper is to report the use the multilevel inverter to be fed into the SRM. The implementation of the multilevel inverter is abl to reduce the Total Harmonics Distortion (THD). Performance comparison are made between the multilevel and previous power electronics circuits that applied to the SRM. The simulation results have been conducted by MATLAB/SIMULINK software.

INTRODUCTION In the electrical motors drive system, one of the most important parts is to design a driver circuit that can efficiently drive the motor to produce the desired output.In the case of the Switched Reluctance Motor (SRM) many researchers have focus on producing suitable drivers for the SRM [1]-[3]. Various type and construction of the SRM motor have been proposed which mainly a different in the employed phase, the number of stator/rotor poles used and torque production mechanism [2]. In this paper, three commonly type of SRM motors are used which can be distinguished by the number of phase. All the SRM motors however have similar parameters as shown in Table 1. All the SRMs are analyzed based on two different control mechanism which are power converter and multilevel inverter. The discussion are focused on the construction, control mechanism and performance comparison result. Table 1.
