摘　　要：本文设计了一种手机充电电路,可以利用高压线感应电流产生5V直流电压。首先介绍了高压线感应原理,并论证了获取高压线感应电压的作为手机充电源的可行性,关键一点是借助火花塞将感应电荷以短脉冲的形式传输到变压器的高压绕组上并形成感应电流;然后设计了手机充电电路的原理图,并对其中参数的进行了计算分析,论证了当变压器输出8V^25V的短脉冲信号时,可以输出稳定5V的直流电压。In this paper, a mobile charging circuit is designed, which can generate 5V dc voltage by using high voltage line induction current. Firstly, we introduce the induction principle of high tension line, and then demonstratethe feasibility of obtaining high voltage line induction voltage as the charging source of mobile phone, the key point is that with the help of the spark plug, induced charge can be transformed to be the form of short pulse with high voltage winding form induced current; Then,we design the mobile phone charging circuit schematic diagram, and analysis the parameters of the calculation, proved that when output with 8 v^25 v of the short pulse signal, can betransformed dc voltage of 5 vstably.
