Abstract: A Switched Reluctance Motor (SRM) drive has wide benefits such as high torque-volume ratio, low manufacturing cost, high dynamic response and wide speed range is required. Many industrial and home appliances have devices of power automatic recycled as a rectifier and driver along with motors. The use of these devices have several non-linearity in the electrical system. Some problems are high harmonics, low power factor, reduced performance and increased consumer cost has produced as a result of non-linearity. In a conventional switched reluctance motor drive, the AC mains power factor is low and the overall Total Harmonic Distortion (THD) rises as a result of harmonics. In instruction to diminish the THD and progress the power factor of the supply mains of SRM, a Bridgeless canonical switching cell (CSC) converter configuration is working in Discontinuous inductor current mode and it is recycled to control the yield voltage of DC and to enhance the power factor at the supply mains. Furthermore, it controls the voltage of DC-link and to find the speed controller of motor side. Here, the SRM with diode bridge rectifier (DBR) and also, with and without converter is analysed. The THD and power factor of the above systems was analysed. The power quality directories are obtained in the array of International power quality principles like IEC 61000-3-2. The drive performance is evaluated by using MATLAB/SIMULINK software.
