This research article proposes an isolated converter integrated with Pulse Width Modulated (PWM)Inverter fed Brushless DC motor (BLDC) for Photovoltaic agric pumping applications. The drift free Optimum Power Point Tracking (OPPT) algorithm is utilized to get maximum power from the Photo Voltaic (PV) Module.The proposed inverter has the features of high voltage gain, galvanic isolation, and better performance even in partially shaded conditions. Photovoltaic Agric Pumping System (PMPS) is aimed to support the rural development and reduce the maximum demand and burden on the distribution system. The proposed one is simulated with Matlab/Simulink software and prototype model alsobuilt with Field Programmable Gate Array (FPGA) controller.The developed systemresults demonstrate that its capability of better solar power utilization for water pumping applications.
