摘　　要：对太阳能电池自动跟踪系统进行分析,提出改进的新方案。新方案通过光敏传感器的合理放置,利用比较电路处理不同位置的光强信号,进而产生控制信号,达到用纯粹的硬件组成电路,做到光源的准确跟踪。其反应速度快,自动跟踪迅速,对光源跟踪效率提高有很大帮助,大大改进太阳能电池的转换效率。尤其是该方案较高的性价比,加上并不复杂的应用电路,具有广泛的应用潜力和相关方面的扩展空间。The automatic tracking system for solar cells is analyzed with a new method proposed to improve the system. In this method, photosensitive sensors are placed reasonably and the signal of light intensity is processed by comparison circuits at different places to create control signal. It can achieve the exact light source tracking through the pure hardware circuitsand help the system work faster and more sensitive .It also improves the conversion efficiency of solar cells. In particular, this methodis cost-effective and has a wide range of potential applications and related aspects of the room for expansion.
