只要有手机，就会有充电器，而品牌机可能会有座充，这对两块电池来说更方便些！为了能够让朋友们更多的了解他的结构及相关应用常识，特作此文，本文以长虹手机M518的充电器为例，进行充分的拆解，希望能给朋友们更多的帮助！

下图为充电器连接座充，充电的情况：
【当然也可以不用座充，直接连接手机进行充电。这时用手机内部的电池保护检测电路来充电和保护】

      该机旅行充电器输入电压为100V~240V交流电，也就是说它可以适用于中国的220V交流电，或其他国家的110V交流电源。该输出电压为5V【经数字表实测为5.06V】电流输出{zd0}约500毫安，输出为直流电或脉动直流电。它的输出接口为USB接口，也就是说它可以作为USB接口的{wn}充电器来用！

      该机的座充，即台式充电器，输入直流5V,输出4.2V【实测4.17V】输出电流350毫安直流电或脉动直流电。

       该机的电池为两块，额定电压为3.7V,容量为1500MAH【单位：毫安时】
注意：锂电的输出放电电压为4.2V~3.7V，充电限制电压4.2V，若高于4.2V，就会损坏锂电或降低寿命或电池过热爆炸，这一点大家应该注意！
      下面还要解释的是：锂电和镍镉电池镍氢电池不一样！这两种电池，额定电压为1.2V，放电电压为1.2V~0V，有记忆效应，而锂电的记忆效应很小。

      下面进行拆解,用十字螺丝刀拧开前面的一颗十字螺丝，就可沿缝隙打开后盖，即可见到内部结构，其实它是一个开关电源，它和变压器降压整流一类的电源，性质是一样的，再简单的说，他就像一块5V的电池。

       虽然各个手机的充电器结构都不一样，但他们的原理都相近相似，上部为高压部分下部为整流稳压部分，经过光耦与上面隔离与传输稳压。红色的为指示灯，最下面为USB接口。总体来说，它比市售兼容充电器要好多了，主要区别，省去了下面稳压部分。上面高压三极管功率较小，容易损坏！该机高压三极管为13003D，为长方形较大塑封，可固定散热片，而市售的兼容高压三极管为13001，为较小半圆塑封 。充电器一般损坏，皆为此管损坏！可用其它充电器同型号管子代换。该充电器高压滤波电容为两个中间串一个电感为二级滤波，滤波效果较好，兼容充电器高压滤波电容为一个，而且体积较小，且耐压较低，当电源电压不稳或升高时，这个电容最容易爆裂损坏，一般是电容上面十字防爆口胀破，而且会流出腐蚀性液体！

     该座充，采用集成电路控制，电池恒流充电，充至4.2V 停止充电有效保护。这比一些分离元件的控制精度好很多。至于一些{wn}充电器，与之相比就差了一些，对于这方面另文介绍分析相关问题。
