一种智能型太阳能路灯控制器的设计与实现

以独立光伏发电系统——太阳能路灯系统为研究对象，采用了MPPT跟踪算法中的扰动法来进行对最大功率点的跟踪控制，设计了DC／DC电力变换电路，并基于PIC16C712单片机设计了一种智能型太阳能路灯的控制器。它集太阳能电池板最大功率点跟踪（MPPT）控制和蓄电池的充放电管理功能于一体，能对蓄电池起到有效过充电和过放电保护，延长蓄电池的使用寿命，提高太阳能路灯系统运行的可靠性。

Design and Implementation of A Novel Solar Street Light System Controller

This paper focuses on stand-alone photovohaic system -- the solar street lighting system, using the perturbation method for the maximum power point tracking control. It designs the DC / DC power conversion circuit, and a controller of the photovoltaic street lamp is designed based on the MCU of PIC16C712 in this paper. It achieves solar panel＇s MPPT control and storage battery＇s charging and discharging management, battery from overcharging and over-discharging effectively. As a result, it can prolong which can protect the storage the service life of the storage battery and improve the reliability of the photovohaic street lighting system.
