Implementation of SPV-powered water pumping system using non-isolated SC converter topology

摘要

Plentiful accessibility of fuels, non-erratic, reliable performance, low maintenance, low cost and high life are the significant factors for solar-PV-powered water pumping scheme for irrigation applications. It is highly used in irrigation system for cultivation where the utility-grid is non-available, hilly areas, forests, etc., by utilizing solar source with energy conversion methodology. However, the performance of overall irrigation scheme relies on energy conversion methodology by using feasible DC-DC converter. In this paper, a novel non-isolated switching cell type DC-DC converter has been proposed for acquiring greater performance of Brushless-DC motor to lift the water from ponds or canal through submersible pump. This observation is clearly presented and validated under steady-state condition by using Xilinx FPGA SPARTAN-6 hardware prototype; results are carried out and compared with various converter topologies.
