你知道充电器上面的DC和AC代表着什么意思?

细心的朋友在充电的时候会注意到许多充电器的上面都会有标着DC和AC这样的字样许多朋友都不明白这代表什么意思,今天电源适配器生产厂家就来告诉大家这些字样代表着什么意思,顺便和给大家普及一下充电器的工作原理。




手机上的DC代(dai)表的是(shi)直流(liu)电(dian)(dian)(dian)(dian),又称“恒(heng)流(liu)电(dian)(dian)(dian)(dian)”,恒(heng)定(ding)电(dian)(dian)(dian)(dian)流(liu)是(shi)直流(liu)电(dian)(dian)(dian)(dian)的一种,是(shi)大小和方(fang)向都不变的直流(liu)电(dian)(dian)(dian)(dian)。恒(heng)定(ding)电(dian)(dian)(dian)(dian)流(liu)是(shi)指大小(电(dian)(dian)(dian)(dian)压高低)和方(fang)向(正(zheng)负极)都不随时间(相对范围内(nei))而变化(hua)(hua)。AC代(dai)表的是(shi)交流(liu)电(dian)(dian)(dian)(dian)。强度与方(fang)向都随时间做周(zhou)期性变化(hua)(hua)的电(dian)(dian)(dian)(dian)流(liu)叫做交变电(dian)(dian)(dian)(dian)流(liu),简称交流(liu)电(dian)(dian)(dian)(dian)我们常见的电(dian)(dian)(dian)(dian)灯(deng)、电(dian)(dian)(dian)(dian)动机等用的电(dian)(dian)(dian)(dian)都是(shi)交流(liu)电(dian)(dian)(dian)(dian)。




目前我国统一(yi)的(de)额定电(dian)(dian)(dian)(dian)(dian)压(ya)为(wei)(wei)220V,手(shou)(shou)(shou)机(ji)(ji)(ji)充(chong)电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)就(jiu)相(xiang)当于是(shi)一(yi)个(ge)小型(xing)的(de)变压(ya)器(qi)(qi),通过手(shou)(shou)(shou)机(ji)(ji)(ji)充(chong)电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)把220V的(de)高压(ya)脉冲(chong)转换为(wei)(wei)5V低压(ya)脉冲(chong),再通过充(chong)电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)转换稳压(ya)等,直(zhi)(zhi)接变为(wei)(wei)5V的(de)直(zhi)(zhi)流(liu)电(dian)(dian)(dian)(dian)(dian),也就(jiu)是(shi)“恒压(ya)”作用。手(shou)(shou)(shou)机(ji)(ji)(ji)充(chong)电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)上面(mian)的(de)变压(ya)器(qi)(qi)变出(chu)来(lai)的(de)是(shi)交流(liu)电(dian)(dian)(dian)(dian)(dian),通过整流(liu)电(dian)(dian)(dian)(dian)(dian)路再变换出(chu)直(zhi)(zhi)流(liu)电(dian)(dian)(dian)(dian)(dian)后给手(shou)(shou)(shou)机(ji)(ji)(ji)充(chong)电(dian)(dian)(dian)(dian)(dian),就(jiu)是(shi)直(zhi)(zhi)流(liu)电(dian)(dian)(dian)(dian)(dian)。这就(jiu)是(shi)手(shou)(shou)(shou)机(ji)(ji)(ji)充(chong)电(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)工(gong)作原理。

另外(wai)电(dian)(dian)(dian)源适配器厂家(jia)也在这里建议您为了充电(dian)(dian)(dian)安全(quan),在选择手机充电(dian)(dian)(dian)器的(de)(de)一(yi)定要选择正规(gui)厂家(jia)生(sheng)产的(de)(de)充电(dian)(dian)(dian)器
