Design and Simulation of DC to DC Boost and SEPIC Converters using MPPT for Photovoltaic system using MATLAB/SIMULINK

Renewable energy sources play a key role and have been the focal point of research efforts all around the world. Among them, Solar energy is a significant source which is suitable for our world. The distinct types of DC – DC Converters connect PV arrays and load for the purpose of impedance matching. To overcome the disadvantages of PV arrays with difference in irradiance level, MPPT algorithm is employed which extracts the greatest power from PV array. DC-DC converter along with MPPT can be beneficial for Standalone PV systems as well as Grid connected systems. This literature represents the simulation of DC-to-DC Boost converter and SEPIC converter for PV array along with Perturb and Observation (P&O) system using MATLAB/SIMULINK. The simulation findings are discussed and performance of boost converter is contrasted with SEPIC converter.
