In this paper, analysis of solar power fed Brushless DC motor (BLDC) motor drive with a boost converter ispresented for water pumping application in irrigation system. Nowa days, the usage of renewable PV sourceis increasing gradually, due to the encouragement of eco-friendly energy sources by providing subsidies forthe installation in the initial states. In the agricultural sector, the water pump system requires a 3-ϕ powersupply, for that we need a separate transmission line and transformers to meet the load demand. In thispaper, a solar power fed BLDC motor water pumping system with boost converter and Voltage sourceInverter (VSI) is presented which reduces the converter switch stress by increasing the voltage transfer gainratio. VSI needs a huge dc link capacitor that is inherently unreliable and is one of the most expensivecomponents of a drive.A MPPT controller is required to extract maximum power from the high penetratingrenewable PV source and also proposes the Current source inverter (CSI) fed water pumping system isdeveloped and examine with same operating conditions. A comparative analysis view in existing method ofsystem replace the VSI with CSI. The performance of system is analyzed with speed settling times at sameoperating conditions. The proposed work is carried out in the MATLAB/Simulinksoftware. A comparativeanalysis is also presented in lucid manner.
