Abstract: Solar power used is the best alternatives. It produces electrical energy which is low cost and efficient, used in pumping application which is simple, robust. The innovation of the work is to implement Perturb and observe algorithm based Maximum Power Point Tracker (MPPT) to boost the systems capability. A PV array is proposed for extracting power and in between the SRM drive and PV array a zeta converter is provided for continuous operation of MPPT thereby shrinking the amount of sudden current flow to the system. An SRM uses a spilt phase capacitor drive for providing the required voltage pulses for phase windings excitation in all of the four phases in SRM. A zeta converter is also proposed as it does not need any additional circuit to limit the sudden flow of current to the system. The SRM drive is controlled with variable DC link voltage of spilt phase converter and it depends upon the different environmental conditions and irradiance level of SPV array. The obtained results have shown that the efficiency of the proposed system is better at higher irradiance levels.
