基于AVR单片机的光伏系统充电器的设计

Design of Photovoltaic System Charger Based on AVR SCM

文章分析了光伏阵列输出能量特点和蓄电池充电特点,提出了一种新的控制方法,并设计出基于AVR单片机的光伏系统充电控制器。试验证明该控制器在充分利用光伏阵列能量同时能提高蓄电池充电效率,较理想地实现了对光伏系统中储能蓄电池的充电控制。

This paper analyzes the energy output characteristic of PV array and the charge and discharge characteristic of batteries, and develops a new control method. A PV system charge eontroller based on AVR singlechip is designed. Experiments prove that the controller takes full advantage of PV array energy and imrpoves the batteries charge efficiency, which achieve the excellent charge control of the energy storage battery in PV system.
