Switched Reluctance Motor (SRM), designed with a number of different power converter circuits and position control system as its major components, are of simple construction, easy maintenance, high speed range, robust and can be employed for unique applications due to the construction of rotor without permanent magnets. These features accounts for its economical pricing and popularity in the automation industry. The presence of acoustic noise and vibration due to torque ripples are the only major limitations of SRM. The conventional converters have many advantages and features such as high efficiency, fast regeneration, high control capability, phase independence and fast response. In addition, there are other limitations that need solution. A major issue in the conventional converters are torque ripple, current ripple and high conduction losses due to a greater number of components. This may reduce the overall efficiency of the machine. So, the reduction of torque and current ripples is the major objective but the speed control of the SRM is also important in medical application. A new converter for SRM drive is developed on the basis of modified bridgeless Single Ended Primary Inductance Converter (SEPIC) has proven to scale down torque ripples, current ripples and also used for speed control of SRM. The performance of the motor drive powered by solar PV and hybrid wind and solar energy is analysed using bridgeless SEPIC converter. The speed of the Switched Reluctance Motor is controlled with Bridgeless SEPIC converter by using PI Controller. The system is simulated using MATLAB SIMULINK and the results are presented and the results shows that the wind energy fed switched reluctance motor with bridgeless SEPIC converter yields a faster settling time compared to other conventional systems.
