摘　　要：针对电子产品在户外使用时电池容量有限,影响用户正常使用的问题,设计了一种便携式多用太阳能充电器。该装置可将太阳能转换成适合电子产品电源,而且能够调节不同电压,满足了用户外即时电源的需求。系统采用STC89C51单片机作为控制核心,由升压、光电转换、充电保护、电压调节和数码显示等功能电路构成。对系统进行了性能测试,结果表明系统具有输出电压范围宽、结构简单和可靠性高的优点,配合市电充电功能,可以满足多种条件下不同负载对充电电压的要求。when electronic products are used outdoors its battery capacity is limited, it can affect users＇ normal use, a portable multi-purpose solar charger is designed. The charger can convert solar energy into charging voltage which fits for battery of electronic products, and can adjust different voltage, with built-in battery can meet portable power supply demand when the user is in outdoors. The system uses STC89C51 microcontroller as the control core, structured by boost circuit, photoelectric conversion circuit, overcharge protection circuit, voltage regulation circuit and digital display circuit. The performance of system is tested, the results show that the system has advantages of wide output voltage range, simple structure and high reliability, with mains charging function; it can meet different load requirements charging voltage under a variety of conditions.
