Research on the Controller of Photovoltaic Power Generation Based on Single Chip Microcomputer

Abstract

As a new power generation system, more and more attention has been paid to photovoltaics (PV). In this paper, the AT89C52 chip is designed as the main controller for the safety and high efficiency of the PV power generation controller. After the input voltage of the solar panel reaches the limit, the voltage is adjusted by a step-up transformer and a li-ion battery management chip. And the li-ion battery is charged by the operation of voltage stabilization and anti-reverse charging. Finally, the correctness and reliability of the design are verified through system simulation.
