Since 1969, switched reluctance motor, due to the advent of inexpensive, high power switching devices has been proposed for variable speed applications. It has wound field coils of a dc motor for its stator windings and rotor does not have windings or magnets. Concentric windings and low resistance, low moment of inertia, brushless, comparable power density, negligible mutual coupling, higher or comparable reliability and low cost are features unique to this machine only. Thus, SRM drives are ideal for many industrial applications. However, SRM drives suffer from poor operating power factor, which will result in more losses in power distribution systems. Therefore, improving the power factor is very beneficial to enhancing commercial competition of SRM drives. Vibration and the resulting acoustic noise in SRM is another disadvantage of this machine. In this thesis we represented the introduction to SRM, its principle of operation and the equivalent circuit. The magnetization characteristics of the 4kw, 8/6 switched reluctance motor are achieved. Simulation of the drive system requires models for the SRM drive subsystems and their interconnections are considered. The simulation procedure is illustrated with results. Converters and their dir=ltr To verify the proposed method, theoretical analyses of mathematical modeling and computer simulations with MATLAB/Simulink have been performed and experimental result is presented. In the end, there is a summary of thesis and suggestions for further studies. Keywords: Switched Reluctance Motor, Power Factor, Current Source Rectifier, Space Vector Moulation.
