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.

The main application of off-grid solar photovoltaic (SPV) systems is water extraction in rural areas where access to the grid is restricted. In this application, photovoltaic (PV) and pump system regulation are crucial to increase its overall efficiency. In this context, this work presents a simple and efficient off-grid SPV water pumping system (SPVWPS). The designed system is based on a DC-DC boost converter, a three-phase DC-AC inverter, and a three-phase induction motor (IM) coupled to the centrifugal pump. The proposed solution is operated using a control strategy that associates an improved fractional open-circuit voltage (FOCV) method for maximum power point tracking (MPPT) and closed-loop scalar control. This association avoids the use of a speed sensor/encoder and a current sensor for the IM. Finally, the effectiveness of the proposed off-grid SPVWPS and its control system for both steady-state and dynamic conditions of insolation change is verified using a 1KVA rated prototype. The relevance of the drive is also checked in various operating conditions and is found to be adequate for pumping water. Moreover, the proposed method guarantees a fast response, less oscillations around the MPP, a system efficiency of 99%, and a high flow rate due to the extraction of maximum power.
