Modelling, analysis and design of synchronous buck converter using soft switching technique for PV energy system

The Photovoltaic (PV) energy system is a contemporary theory in use, which advances status because of growing reputation to study on different causes of energy over exhaustion of the conformist fossil fuels universal. The renewable sourced are commercialised to obtain power from the sun in efficiently and outfit them to the obtainable loads deprived of moving their presentation. In our work, we present the exquisite design of Synchronous Buck Converter with the application of Soft switching Modelling 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. Now, the converter concepts cast-off, usages extra MOSFET which eliminates losses of conduction which is originate conspicuously in the simple buck converter, thus performance of the converter is enhanced. 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 order of maintaining constant output voltage, overall converter efficiency etc. We also studied and modelled, MPPT for the given PV energy system and the simulations are carried out in MATLAB-Simulink environment. More, the relative study is proposed among the both synchronous and simple Buck converter. At last we show that the output voltage remnants fixed irrelevance 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 in MATLAB/Simulink software. The suggested converter is simulated in the MATLAB Simulink software and suggested converter is implemented practically to confirm the results of theor
