Fuzzy Logic Control of Photovoltaic Lead-Acid Charging System

Article Preview

Abstract:

A new photovoltaic solar cell charging system with fuzzy logic control is proposed and designed. This kind of solar energy storage system is composed of a solar cell, a charger, batteries, a buck converter and a digital signal processor. It mainly applies a low-voltage level translator to control the pulse charging current of a lead-acid battery and also combines the fuzzy control method to improve the charging efficiency, suppress the abnormal temperature rise in the battery, lengthen the battery life-time, reduce the additional waste, etc..Experimental and simulated results are shown to demonstrate and compare the validity of the system and verify the effectiveness with each other.
