摘要
如何方便便携式电子设备的充电一直是相关设计人员追求的目标。设计的一种实用太阳能移动电话充电器,系统以运算放大器为控制核心实现功能控制;同时用MC34063芯片实现DC DC变换。首先介绍系统工作原理,然后对电路做比较详细的分析。最后给出测试结果。从性价比来看该设计是一项优秀的设计。
How to facilitate portable electronic equipments to be charged is always the target aimed by relative designers. This paper introduces the design of an applied solar- energy- based charger of mobile phone, which employs operational amplifiers as controlling core,and MC34063 chip as DC-DC converter. The working principle is firstly introduced,then detailed analysis to circuits is given,finally test result is presented. The performance to price ratio indicates that it is an excellent design.
