PERFORMANCE ANALYSIS OF FUZZY CONTROLLER BASED ZVS DC-DC CONVERTER FOR SOLAR ENERGY CONVERSION SYSTEM

AbstractThis present work emphasis on the improvement of resonant converter (DC –DC converter) for solar energy conversion system (SECS). It accentuations on plan and exh ib iting periods of the distinctive constituents of the SECS like the rudimentary model of zero voltage switching (ZVS) converter, inverter, fuzzy logic controller, best maximum power point tracking (MPPT) system utilizing MATLAB/ Simulink. Here, a resonant converter represents the static and dynamic characteristics of an actual solar irradiance have been developed for simulation tests. The irradiance and temperature changes circumstances are performed using the resonant converter, which consist of PV system, whose control is implemented using Fuzzy logic control unit and MATLAB/ Simulink. This PV module can achieve maximum power using Perturb & Obserb algorithm. Under various abnormal conditions like change in irrad iance and temperature, step change in irradiance etc. The control system is executed on a fuzzy logic control unit . Speculative outcomes are exhib ited utilizing a 200W model of SECS to demonstrate the better aftereffects of the propelled framework and their control under steadystate and dynamic conditions.
