摘　　要：根据风能和太阳能在时间和空间上的能量互补,设计了一种小功率风光互补路灯控制器。该控制器主要由升压型直流变换电路和单片机控制电路组成,可根据蓄电池的不同储能状态对光伏板与风力机输出进行功率控制。控制器使用微芯公司的PIC16F系列8位单片机,单片机输出基准信号到脉宽调制芯片,芯片根据负反馈输出不同占空比的PWM波来控制系统输出,控制器兼有过充电、过放电和短路保护等功能。实验证明,所设计的控制器能利用风能和太阳能精准地给蓄电池充放电并实现各种保护。According to the complementary characteristic of solar and wind resource , this paper designed a low-power solar and wind hybrid streetlights controller .The controller is mainly composed of boost type dc-dc converter and MCU control circuit .And the controller could intelligently complete the power transition base on the battery charging status .The MUC used is PIC16F series which provides the reference voltage to PWM control chip .The chip is upon the negative feedback to modulate the output drive signal .The controller also has protection circuit including over-charging circuit , over-discharging circuit , and short-circuits.Experimental results indicate that this controller could accomplish the charging process upon solar and wind hybrid resource exactly and complete more protective functions .
