Closed Loop Control of Flyback Converter with PV as a Source

Abstract

In today’s scenario, Conventional resources are limited and practice followed for electrical power generation has a fetal effect on the environment, which forced us to seek alternatives. The renewable energy, specially Photovoltaic (PV) sources seem to be a solution for it. As the PV sources are integrated into the grid through converters. Hence, power electronic converters have emerged as an integral part of renewable energy generation systems for generating electrical energy. In this paper, Type 2 based closed-loop control analysis of flyback converter with PV as a source along with Maximum Power Point Tracking (MPPT) is done. Type 2 compensation makes the close loop control of the system sturdy for all the variations occured in the system. The proposed technique is simulated in MATLAB/SIMULINK and the results are analyzed.
