便携式野外充电器的设计

Design of portable outdoor charger

为了解决手机电源突发断电,满足手机随时随地进行充电的目的,设计了一种太阳能及手摇式多功能手机充电器。使用太阳能电池板,经电路进行直流电压变换后给手机电池充电。手摇发电机产生波动较大的电压后,利用电压变换电路将输入电压整流、滤波、稳压后,得到稳定的充电电压。对220V工频交流电进行整流、滤波、稳压后得到充电电压。后经充电管理电路给电池充电,充电完成后自动停止。该设计具有适用于旅行中野外使用的特点。

In order to solve the problem that the power supply of mobile phones interrupts suddenly, and meet the need that the mobile phone can get charged anytime and anywhere, a multifunction charger with solar panels or hand-cranked generator is designed. Its basic principles are as follows= the current produced by solar panels is converted to DC by voltage transformation circuit, and then charges mobile phones, and the hand-cranked generator generates a fluctuating current which flows through rectifier, filter, regulator and voltage conversion circuit to realize the voltage conversion from 220 V industrial frequency AC to a proper voltage. It can charge the batteries of mobile phones controlled by charging control circuit. The charging action stops automatically when the battery is full. It is especially useful when People are travelling or outdoor.
