1、摘要化石能源的日益枯竭、人们对环境保护问题的重视程度也在不断提高,寻找洁净的替代能源问题变得越来越迫切。太阳能作为一种可再生能源它具有取之不尽、用之不竭和清洁安全等特点,因此有着广阔的应用前景,光伏发电技术也越来越受到人们的关注,随着光伏组件价格的不断降低和光伏技术的发展,太阳能光伏发电系统将逐渐由现在的补充能源向替代能源过渡。使用手机的人都有过这样的经历,外出或旅游时电池突然没电了,因不能及时找到或没有220V市电而无法给手机充电,影响了手机的正常使用。为了解决这一问题,本课程设计介绍一种多用太阳能手机充电器,利用单片机
2、控制,将太阳能经过电路变换为稳定直流电给手机充电,并能在电池充电完成后自动停止充电,还可作为一般直流电源使用,从而摆脱对市电的依赖而获得通信的自由。与常规的充电器相比,太阳能充电器有着明显的优势。关键词:太阳能,电池,单片机,智能,BUCK变换器Multi-purposesolarmobilechargerAbstractIncreasingdepletionoffossilenergy,it'semphasisonenvironmentalprotectionarealsorising,lookforcleanalter
