Exploitation of buck-boost converters for executing perturb and observe mppt in the pv system

Renewable energy is best option for fulfilling energy requirements in rural and needy areas. The main problem with its implementation is cost and efficiency. As far as cost is concerned it has been suppressed by advancement in Indigenous Technology and support form Govt. of India, whereas increment in efficiency is different matter. For increasing the efficiency of renewable sources like Solar PV Panels various methods have been adopted, one of which is Maximum power point tracing(MPPT). MPPT system is an electronic system that may be ready to compel the utmost power from a PV system. It doesn't involve any mechanical element that ends up in the movement of the module's dynamic, their direction and create them face straight towards the sun. MPPT system may be a fully electronic system which might deliver most allowable power by varying the operative purpose of the modules electrically. In this paper we present execution of Perturb and Observe MPPT exploiting buck-boost Converters. Results for each various combination have been recorded. The simulation has been done in software of MATLAB Math works.
