Buck-Boost Converter Using Fuzzy Logic for Low Voltage Solar Energy Harvesting Application

This research paper is about implementing energy harvesting solutions to maximize the output voltage of solar panel and to harvest the waste energy from solar panel for low voltage application. As the range of applications for solar energy increases, the improved materials and methods used to harness this power source needs to be developed. Major influences on overall efficiency include solar cell efficiency, intensity of source radiation and storage technique. To circumvent this problem this technique is implemented by solar energy system independent on irradiance and temperature developed by using buck-boost converter. Fuzzy logic controller generate variable duty cycle depends on variable solar panel voltage. Generated duty cycle is applied to buck-boost converter on which output is depends which is used for low voltage application such as battery charging. The charge battery will be used for lightening the parking, staircase and quoridor etc.
