If we start forecasting in the view of electrical energy generation, in the upcoming decade all the fossil fuels are going to be extinct or the worst they are going to be unaffordable to a person living in typical circumstances, so renewable power energy generation systems are going to make a big deal out of that. It is extremely important to generate and convert the renewable energy with maximum efficiency. In this project, first we study the characteristics of low power PV array under different values of irradiance and temperature. And then we present the exquisite design of Synchronous Buck Converter with the application of State Space Modeling to implement precise control design for the converter by the help of MATLAB/Simulink. The Synchronous Buck Converter thus designed is used for portable appliances such as mobiles, laptops, iPod’s etc. But in this project our main intention is to interface the PV array with the Synchronous Buck Converter we designed, and we will depict that our converter is more efficient than the conventional buck converter in terms of maintaining constant output voltage, overall converter efficiency etc. And then we show that the output voltage is maintaining constant irrespective of fluctuations in load and source. And finally we see the performance of Synchronous Buck Converter, which is interfaced with PV array having the practical variations in temperature and irradiance will also maintain a constant output voltage throughout the response. All simulations are carried under MATLAB/Simulink environment. And at last experimental work is carried out for both conventional buck converter and also for synchronous buck converter, in which we observe the desired outputs obtained in simulations.
