隨著(zhu)科技的(de)(de)發展(zhan)，人類(lei)社(she)會的(de)(de)進步，現在的(de)(de)電(dian)子產(chan)(chan)品特別的(de)(de)多，而且占了我們生活(huo)的(de)(de)主力面。由于電(dian)子產(chan)(chan)品種類(lei)繁多，用(yong)途(tu)也各(ge)不相(xiang)同。所以(yi)說大多數人并不知道這些(xie)電(dian)子產(chan)(chan)品中間(jian)的(de)(de)區別。今天(tian)我們就來看(kan)一(yi)下我們日常生活(huo)中最常見的(de)(de)三個電(dian)子產(chan)(chan)品，電(dian)源適配器，開關(guan)電(dian)源，充電(dian)器之間的區別。

一、充電器

首先我們要說的就是USB充電(dian)器。這可(ke)(ke)能也(ye)(ye)是(shi)大家最了解(jie)的(de)(de)一種(zhong)了，因(yin)為(wei)不管(guan)是(shi)我們(men)的(de)(de)手機(ji)(ji)還是(shi)相(xiang)機(ji)(ji)，基本都要用(yong)到(dao)充電(dian)器。但是(shi)大家可(ke)(ke)能也(ye)(ye)只是(shi)了解(jie)了它表面的(de)(de)東西。用(yong)書面語言來(lai)說(shuo)，充電(dian)器屬于一種(zhong)電(dian)器的(de)(de)附件。是(shi)一種(zhong)電(dian)子(zi)半導體，也(ye)(ye)可(ke)(ke)以說(shuo)是(shi)一種(zhong)電(dian)流變換(huan)器，將交流電(dian)變成直流電(dian)來(lai)供設備使(shi)用(yong)。手機(ji)(ji)相(xiang)機(ji)(ji)之類的(de)(de)設備一直在發(fa)(fa)展，那么充電(dian)器作為(wei)附屬電(dian)器也(ye)(ye)將有很(hen)好(hao)的(de)(de)發(fa)(fa)展和應(ying)用(yong)的(de)(de)前景。

二、電源適配器

對于電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)可能大部分人(ren)不是(shi)(shi)(shi)很了(le)解。簡單點(dian)來說電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)就(jiu)是(shi)(shi)(shi)一(yi)種(zhong)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)變換設備(bei)。一(yi)般體積比(bi)較的(de)小。但是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)的(de)種(zhong)類也是(shi)(shi)(shi)多(duo)(duo)種(zhong)多(duo)(duo)樣(yang)的(de)。比(bi)如直流輸出(chu)型(xing)和交流輸出(chu)型(xing)的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)。連(lian)接方式(shi)也是(shi)(shi)(shi)多(duo)(duo)種(zhong)多(duo)(duo)樣(yang)的(de)，有(you)(you)的(de)是(shi)(shi)(shi)插在墻上的(de)，有(you)(you)的(de)是(shi)(shi)(shi)桌面式(shi)的(de)。除(chu)了(le)這些，電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)的(de)應(ying)用就(jiu)更廣泛了(le)，不管是(shi)(shi)(shi)筆(bi)記(ji)本電(dian)(dian)(dian)(dian)(dian)腦(nao)，還是(shi)(shi)(shi)電(dian)(dian)(dian)(dian)(dian)話子母(mu)機(ji)，小孩子用的(de)復(fu)讀機(ji)，游戲機(ji)還是(shi)(shi)(shi)我(wo)們聽歌用的(de)隨身聽，都(dou)有(you)(you)應(ying)用到電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)。而且(qie)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)發展的(de)已經比(bi)較成熟(shu)了(le)，一(yi)般的(de)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)都(dou)是(shi)(shi)(shi)具(ju)有(you)(you)自(zi)動檢測功能的(de)。而且(qie)，電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)配(pei)(pei)(pei)(pei)器(qi)(qi)上面都(dou)標有(you)(you)電(dian)(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)(dian)流，我(wo)們在使用的(de)時候(hou)就(jiu)有(you)(you)個參考。

三、開關電源

開關電源是一種控制電壓和電流輸出的一個閥門。打開了就能流通，關掉了就斷流。開關電源有三個條件，那就是直流，高頻和開關。在現代社會中，開關電源的應用比USB充(chong)電(dian)(dian)器(qi)，電(dian)(dian)源(yuan)適配器(qi)更(geng)(geng)要廣(guang)泛。因為但凡(fan)是(shi)電(dian)(dian)子產品，都會要用到開關(guan)電(dian)(dian)源(yuan)。所以說，開關(guan)電(dian)(dian)源(yuan)的(de)發(fa)(fa)展要更(geng)(geng)成熟的(de)多。經過這么多年經濟(ji)的(de)發(fa)(fa)展，開關(guan)電(dian)(dian)源(yuan)也不斷的(de)進行創新，而且從長遠來看，開關(guan)電(dian)(dian)源(yuan)的(de)發(fa)(fa)展前景是(shi)非常廣(guang)闊(kuo)的(de)。

總的來說，USB充(chong)電器(qi)它只能用一(yi)(yi)根線連接(jie)來給設(she)備(bei)進行充(chong)電，不能直(zhi)接(jie)應(ying)用于設(she)備(bei)上。但是電源適配器(qi)不僅能給電器(qi)充(chong)電，還可(ke)以直(zhi)接(jie)在電源上應(ying)用，既能充(chong)電也能供電，而電源開關就很好區別了，只是一(yi)(yi)個開關的閥門而已。
