  在如今这种通信技术发达的环境下,手机已经成为了我们生活中再也不可缺少的一部分,而手机充电器作为手机的充电设备,重要性也是不言而喻。那么手机充电器在充电的过程中输出的电流是直流还是交流呢?下面就由充电器厂家为您讲解一下手机充电器输出的是直流还是交流电。
  In today's developed under the environment of the communication technology, mobile phones have become an indispensable part of our life no longer, and mobile phone charger for mobile phone charging equipment, importance is self-evident.So mobile phone chargers in the process of charging output current is dc or ac?Here are the charger manufacturers for you explain phone charger output is dc or ac.
  手机充电器上面的变压器变出来的是交流电,通过整流电路再变换出直流电后给手机充电,就是直流电。直流电标志是DC,交流电标志是AC,手机充电器一般都是直流电,而交流电主要用于传输。
  Mobile charger change out of the transformer is ac above, through the rectifier circuit to transform a direct current (dc) for charging the mobile phone after, is the direct current (dc).Direct current is DC, AC logo is AC, cell phone chargers are generally not direct current, alternating current (AC) is mainly used for transmission.
  手机充电器输出电流都是直流,手机充电器在充电时,比如说500mA的充电器,充电是从0-500mA,或者500mA-0mA这样的一个充电曲线的,当手机电池电量用光的时候,充电的时候就是用的最大电流充的。
  Mobile charger output current is dc, mobile phone charger when charging, such as 500 ma charger, rechargeable from 0-500 ma, or ma - 500 0 ma such a charging curve, when the cell phone battery run out, charging time is to use the maximum current of charger.
  慢慢的电池的电量越来越多的时候,手机充电器的电流就越来越小,当电池完全充满的时候,手机充电器的充电电流就为零了。这是手机充电器的限流电路决定的。
  When the battery power more and more slowly, phone charger current is smaller and smaller, when the battery completely full of mobile phone chargers charging current is zero.This is the current limiting circuit phone charger.
  手机充电器输出的是直流还是交流电就分享到这里。目前国家统一的额定电压为220V,手机充电器就相当于是一个小型的变压器,通过手机充电器把220V的高压脉冲转换为5V低压脉冲,再通过充电器的转换稳压等,直接变为5V的直流电,也就是“恒压”作用。
  Phone charger output is dc or ac will share here.The current national unity of the rated voltage of 220 v, cell phone charger is quite so a small transformer, through the mobile phone chargers convert 220 v high voltage pulse to 5 v low voltage pulse, and by the transformation of the charger voltage regulator, etc., directly into 5 v direct current, namely "constant pressure".
