摘　　要：针对太阳电池输出伏安特性曲线的特点,设计了基于单片机控制的用于野外设备的太阳能充电器。该充电器利用单片机C8051F320的可编程计数器/定时器阵列(PCA)的工作方式,改变占空比,使系统以最大功率工作,增强太阳电池的转换效率。For volt-ampere characteristic curve of solar cells, the solar charger based on the controlled SCM and used for field equipment, was designed. The work mode of programmable counter/timer array （PCA） of C8051F320 was used by the charger to change the duty cycle and to achieve maximum power tracking technology, and then the conversion efficiency of photovoltaic cells was enhanced.

关 键 词：太阳电池 C8051F320 最大功率
