摘　　要：针对现有太阳能系统普遍存在的效率低,寿命短,运行不稳定等问题,提出一种应用于太阳能照明系统的新型智能控制器。实现了基于芯片CN3717的蓄电池能量智能管理,芯片对蓄电池在不同状态下进行充电,延长了蓄电池的寿命,由光敏电路控制的负载电路也极大程度提高了蓄电池的使用效率,满足了太阳能照明系统在不同工作状态下的稳定运行与准确切换的要求,实验结果验证了该方案的有效性。Aiming at the problem of the lower efficiency, the shorter battery life and instabilities of the photovohaic lighting systems, this paper presents a cost-effective and intelligent controller for photovohaic lighting systems based on a cheap CN3717.The system performance has been enhanced by the proposed energy management. The efficiency of the battery has been enhanced by the photosensitive circuit which meets the stability of photovoltaic lighting system in the different status. At last, experiment is conducted to verify the feasibility of the charger.
