摘要
在户外,为解决数码产品续航/待机问题,设计一款多功能太阳能移动电源,使用典型芯片和常用元件设计控制电路,将太阳能充电和手摇充电合为一体。单晶硅太阳能PV板将光能转换为电能,经直-直流变换电路,在标准USB口输出DC 5 V,实现太阳能充电。手摇发电机将机械能转换为电能,经交-直流变换电路后稳压输出,实现手摇充电。选用LM2575代替传统三端集成稳压芯片设计稳压电路,经过电路调试和实验,太阳能和手摇模块均可供手机及其他5 V数码产品充电,充电可靠,成本低,体积小,另外增加照明和电量指示等辅助功能,更加实用。
In order to solve the digital product range/standby problem in the open air, a multifunctional solar mobile power supply based on typical chips and common components was designed. It combined solar charging with manual charging. The monocrystalline silicon solar PV panels converts light energy into electrical, then DC-DC conversion circuit output DC 5 V at standard USB, solar charging has been realized. Hand generator converts mechanical energy to eleetrieal,？after AC-DC conversion circuit generates voltage, manual charging has been realized. LM2575 chip instead of traditional three-terminal voltage chip, through circuit debugging and experiment, the solar and hand modules are available for mobile phones and other 5 V digital products, charging reliable, low cost, small size and more practical with the additional auxiliary functions such as lighting and power indicator.
