太阳能超级电容的实验室用开关电源设计 摘 要 太阳能的存储是太阳能产品发展的关键，目前主要采用各种电池，但是电池的充电时间长、寿命短以及不环保一直是太阳能产品发展的瓶颈，而超级电容器作为一种充电快、寿命长、绿色环保型储能元件，它给太阳能产品的发展带来了新的活力。 近年来,在许多领域种越来越多地应用到开关电源。例如邮电通讯、军事设备、交通设备、仪器设备、工业设备、家用设备等方面。并且开关电源在这些取得显著效益。全球有一定规模的开关电源制造厂商约500多家。开关电源能够如此迅速的发展，最主要的原因还是来源于巨大的市场需求。此外，磁性材料、电子器件、控制理论、变换技术等技术的发展以及仿真软件的不断涌现与完善，使得开关电源的研发水平和制造水平大大提高，由此电源开关具有了高功率密度、高可靠性、高效等特点。这些都极大地推动了开关电源的发展和完善。可以说，开关电源处于电源技术的核心地位，它是在新型功率器件、新型电路拓扑不断出现的条件以及实际需要的推动发展起来的。因此研究开关电源具有很好的科研价值和经济价值。 关键词：太阳能；超级电容；开关电源  SUPER CAPACITOR LABORATORY WITH SOLAR POWER SWITCH DESIGN ABSTRACT In recent years, in many fields kind of more and more applied to switch power supply. Such as telecommunications, military equipment, transportation equipment, instruments, industrial equipment, household devices, etc. And switching power supply in these made remarkable benefits. Global a sizable switching power supply manufacturer ShangYao many 500. Switching power supply can so the rapid development, the main reason or from the huge market demand. In addition, magnetic materials, electronic device, control theory, such as the development of the technology transformation technology and the simulation software emerging and improved, making the switch power development level and manufacturing level greatly improved, thus the power switch has the high power density, high reliability, high efficiency, etc. These are greatly promote the development and perfection of switch power supply. Can say, switching power supply in the power of technology key position, and it is in the new power devices, new circuit topology appear constantly condition as well as the actual need to push up the development. So the switch power supply has the very good scientific research value and economic value. Key words: Solar energy; Super capacitor; Switch power supply  目 录 1 绪论 1 1.1 课题背景及目的 1 1.2 国内外研究状况 3 1.2.1 国内外超级电容的发展现状 3 1.2.2 国内外开关电源的研发现状 3 1.3 课题研究方法 4 2 太阳能充电系统研究 5 2.1 最大功率点跟踪 5 2.2 MPPT的硬件设计 5 2.3 软件分析 6 3 超级电容储能电源的
