摘要
针对野外远离市电供电的系统或者用户的电源供应问题,文中设计了一个智能化太阳能充电用电管理系统,采用MPPT最大功率跟踪方法,控制PWM信号调节BUCK电路的输出,使太阳能电池与蓄电池尽量处在一种相互匹配的状态下,并采用阶段充电方式,采用STC12C5A60S2单片机,集成AD转换功能与PWM信号输出,简化了系统的设计,通过实验,该系统能够有效地提高充电效率以及对蓄电池的保护功能。
According to the problems of the field away from the utility power supply system, this paper designed an intelligent control system of solar, including charging, power supply. With the theory of Maximum Power Point Tracking, regulating signal PWM, to change the output of BUCK circuit, match solar modules and batteries. Adopts the step charging ways, and single-chip STC12CSA60S2, integrated AD converter and PWM signal output, simplify the designing work. Through the experiment, it can improve the efficiency of charging and protect the battery.
