Abstract

The project proposes a new converter for photovoltaic system which is substantially high performance oriented. Furthermore, the lack of batteries replacement water pumping systems without the use of chemicals are responsible for the failure of such systems in isolated areas. The converter is designed to drive a three-phase induction motor directly from photovoltaic system. The majority of commercial systems use low-voltage (PV) energy. The use of three-phase induction motor presents a suitable replacement of dc motor though by the use of dc motor we can directly drive by means of converter dc supply, but due to its lack of performance and reliability, we have opted for three phase induction motor. In the developed technique, there is no specialized personnel for operating and the system is based on a current-fed multi-resonant converter also maintaining these motors. Here, we make use of the TIBC topology such that they are found to be made of Buck Boost converter which will both stabilize and boost the output supply. Thus, the project will be a low cost high efficiency water supply duo for agricultural industry. Though solar energy based water supply system is being developed for the past 20 years, this project will be a phenomenal change and development of renewable energy that could be used in agricultural industry projects.
