Design of Solar Energy Collecting & Controlling System

Abstract

In this paper, the solar energy collecting and controlling system is designed to realize the function of solar mobile power. The system can be combined with the solar panels to achieve photoelectric conversion, packed in the knapsack or directly worn on the clothes to provide the function to charge the mobile intelligent terminals at any time. In the circuit, the input voltage from solar energy is stabilized by using LM317 regulator integrated chip. The XL4015E1 switching step-down chip is used to reduce the input voltage to reach the voltage range required for load charging. The constant current and voltage charging circuit is used to charge the lithium battery. Set the LED light to show the charging process and charging mode, control digital tube displays by the single chip STM8S103F3P6.
