Modeling, Simulation of Buck Boost Converter with MPPT and Control of Battery Charging Application

Presented paper depicts the modeling, simulation of Dc-Dc converter and control of battery charging application with less oscillation during switching of MOSFET. Proposed paper deals with the implementation and design of an actual time maximum power point tracking (MPPT) for (PV) system aimed to increase efficiency of energy conversion. As the photovoltaic system has a non-linear behavior of i-v characteristic curve and because of solar irradiance and temperature changes is directly proportional to the maximum power point. Therefore, to obtain maximum power from Solar array the (P&O) Perturbation and Observation MPPT algorithm is implemented using Buck Boost converter. The charismatic characteristics of PV array at different irradiance and temperature is simulated.
