Abstract
This paper presents a simple, cost-effective scheme for agricultural pumping system. It consists of PV array, canonical switching cell converter (CSCC), Boost inverter, and induction motor. The input power for the boost inverter is obtained from the photovoltaic (PV) based CSCC. The requirement of lower number of components and nonpulsating input current are the superior features of the CSC converter. The conversion of DC voltage obtained from the PV based CSC converter system into high voltage AC using the boost inverter is the main feature of the proposed scheme. Extraction of maximum power from the PV system is ensured in this paper by means of a P & O MPPT algorithm. Because of a high step up CSC converter and boost inverter, this scheme requires fewer number of PV arrays to power the induction motor for pumping system. Effectiveness of the proposed scheme is verified through MATLAB/SIMULINK environment and necessary results are presented.
