摘要
提出了一种基于ATMEGA8L单片机的12/24V光伏电源系统。硬件电路辅以TL494芯片等器件实现电源PWM脉宽调制充电、蓄电池12/24V电源电压自动识别、切换、充电电压/电流自动调节、放电过程负载短路/过载保护等控制功能;软件采用C语言实现模块化编程,由主程序及若干功能子模块组成。
A 12/24V photovoltaic power based on ATMGA8L MCU is proposed. TL494 chip is used to implement PWM charging, 12/24 power voltage auto recognition, switching, charging voltage/current auto adjustment, discharging protection. The software which has a main program and many function modules is programed in C language.
