摘　　要：最大功率点跟踪是太阳能电池应用研究中的重要问题之一,其转换电路主要有Buck电路、Boost电路和SEPIC电路.通过对3种转换电路的分析比较,得出了各自的适用范围.根据实验结果提出了LED照明调光的方法.应用该方法不仅可以节省能量,而且可以延长LED的寿命,降低结温.The highest power tracing is an important issue on sunpower battery applicational research. The transforming circuit mainly includes Buck circuit, Boost circuit and SEPIC circuit. Through the analysis and comparision of the three circuits, obtains the applicable scope of each cir- cuit. Based on the experimental results, proposes the method of dimming of LED illumination. For appling the method, it is not only save the power, but also prolong the life span of LED.
