摘要
在外旅游或者没有电源的情况下,便携式光伏发电箱可以实现手机、手电筒、剃须刀等能量补给及夜晚照明。文章主要介绍了光伏发电箱的太阳能发电系统,该系统由光伏电池、蓄电池、控制器、逆变器、数据采集板、上位机等几部分组成;文中对该系统各部分的功能和相互联系进行了分析;重点叙述逆变器的设计,包括电路结构、DSP软件的设计、PWM波形的产生原理;通过数据采集板和上位机可实时监测系统的运行状况,具有一定的市场潜力。
Portable solar power box allows energy supplies of mobile phones,flashlights,razors and night lighting in case there is no power when travelling.This paper introduces the solar photovoltaic system of the portable PV power box.The system consists of photovoltaic cells,batteries,control unit,inverter,data acquisition board and PC.The functions of each part of the system and linkages are analyzed.The paper mainly describes the design of the inverter,including circuit,DSP software design and PWM waveform generate theory.It has market potential and the real-time monitoring could be relized through the data acquisition board and PC systems.
