摘　　要：本文设计并实现基于DSP光伏发电LED航标灯系统。该系统能够快速准确地跟踪太阳位置,获得最大的辐射能量,并且以最大功率输出到蓄电池中。系统中利用Buck-boost电路实现对蓄电池的充电,Fly-back电路驱动LED恒流工作。This paper presents the design and implementation of a LED pharos system based on a DSP. This system can track the location of the sun the greatest power output to the battery. quickly and accurately, and receive the maximum radiation energy with In this research, Buck-boost converter is used to charge the battery, and Fly-back circuit is adopted to drive LED working on constant current.
