Cost Effective Design & Control of DC-DC Converter for Solar PV System with MPPT

The current critical condition of fossil fuel crisis is rapidly increasing day to day and its harmful impact to the climate and environment is serious matter to take care. Thus, green energy or renewable energy is the only possible solution coming out of this context and solar energy is one of the most effective energy resources of these green energy system. In this manuscript we have discussed about a PV (photovoltaic) generation system with battery and capable of extracting maximum power output by using P&O type MPPT technique and it is working in isolated mode. As per the information given above, we have built a prototype of the system using a PV module capable of generating 1kW energy and the MPPT method has been implemented with the mean of using P&O technique. As the efficiency of the PV generation system is always a matter of concern the MPPT technique has been used to extract maximum power output from the PV array at any environmental condition. Here we used DC-DC converters as MPP trackers. A detailed model of the system first simulated using MATLAB/Simulink and later on the results have been validated to check effectiveness and suitability in the point of view of performance of the prototype has been added to this article. In each step of our designing of the prototype we tried to make it a cost-effective, simple and efficient model than the other existing models found in market.
