Comparative Analysis onVSI and CSI based Solar Photovoltaic Source Fed BLDC Motor Drive with Boost Converter for Water Pumping System

Abstract

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