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