隨著科(ke)技的(de)發展，人(ren)類社會的(de)進步(bu)，現在(zai)的(de)電(dian)(dian)子(zi)(zi)產品(pin)(pin)特別(bie)的(de)多(duo)，而且占(zhan)了我們生活的(de)主力面(mian)。由于電(dian)(dian)子(zi)(zi)產品(pin)(pin)種(zhong)類繁多(duo)，用途(tu)也各不相同。所以說大多(duo)數人(ren)并不知道(dao)這(zhe)些(xie)電(dian)(dian)子(zi)(zi)產品(pin)(pin)中間的(de)區(qu)別(bie)。今天我們就來看(kan)一下我們日(ri)常生活中最(zui)常見的(de)三個(ge)電(dian)(dian)子(zi)(zi)產品(pin)(pin)，電(dian)(dian)源適(shi)配器，開關電(dian)(dian)源，充電器之間的(de)區別。

一、充電器

首先我們要說的就是USB充(chong)(chong)電(dian)(dian)器(qi)(qi)。這(zhe)可能(neng)也是(shi)大家最了解(jie)(jie)的(de)一(yi)種(zhong)了，因為不管是(shi)我們的(de)手機還(huan)是(shi)相機，基本都要用到充(chong)(chong)電(dian)(dian)器(qi)(qi)。但是(shi)大家可能(neng)也只是(shi)了解(jie)(jie)了它表面的(de)東西。用書面語言(yan)來說(shuo)，充(chong)(chong)電(dian)(dian)器(qi)(qi)屬于一(yi)種(zhong)電(dian)(dian)器(qi)(qi)的(de)附件。是(shi)一(yi)種(zhong)電(dian)(dian)子(zi)半導體，也可以說(shuo)是(shi)一(yi)種(zhong)電(dian)(dian)流(liu)變換器(qi)(qi)，將(jiang)交(jiao)流(liu)電(dian)(dian)變成直流(liu)電(dian)(dian)來供設備使(shi)用。手機相機之類的(de)設備一(yi)直在發展，那(nei)么充(chong)(chong)電(dian)(dian)器(qi)(qi)作(zuo)為附屬電(dian)(dian)器(qi)(qi)也將(jiang)有很好的(de)發展和應用的(de)前景(jing)。

二、電源適配器

對于電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)可能(neng)大部分人不是(shi)(shi)(shi)(shi)很了解(jie)。簡(jian)單點來說(shuo)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)就(jiu)是(shi)(shi)(shi)(shi)一種(zhong)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)的(de)(de)變換(huan)設備(bei)。一般(ban)(ban)體積(ji)比較(jiao)的(de)(de)小(xiao)。但是(shi)(shi)(shi)(shi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)的(de)(de)種(zhong)類也是(shi)(shi)(shi)(shi)多(duo)種(zhong)多(duo)樣的(de)(de)。比如直流(liu)輸出(chu)(chu)型和交流(liu)輸出(chu)(chu)型的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)。連接方式(shi)也是(shi)(shi)(shi)(shi)多(duo)種(zhong)多(duo)樣的(de)(de)，有(you)(you)的(de)(de)是(shi)(shi)(shi)(shi)插在墻上的(de)(de)，有(you)(you)的(de)(de)是(shi)(shi)(shi)(shi)桌面式(shi)的(de)(de)。除了這些，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)的(de)(de)應用就(jiu)更廣(guang)泛了，不管(guan)是(shi)(shi)(shi)(shi)筆記本(ben)電(dian)(dian)(dian)(dian)腦(nao)，還是(shi)(shi)(shi)(shi)電(dian)(dian)(dian)(dian)話子母(mu)機(ji)，小(xiao)孩子用的(de)(de)復讀機(ji)，游(you)戲(xi)機(ji)還是(shi)(shi)(shi)(shi)我(wo)(wo)們聽(ting)歌用的(de)(de)隨身聽(ting)，都(dou)有(you)(you)應用到電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)。而且(qie)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)發展的(de)(de)已經比較(jiao)成熟(shu)了，一般(ban)(ban)的(de)(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)都(dou)是(shi)(shi)(shi)(shi)具有(you)(you)自動檢測功能(neng)的(de)(de)。而且(qie)，電(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)(yuan)適(shi)(shi)(shi)(shi)配(pei)器(qi)(qi)上面都(dou)標有(you)(you)電(dian)(dian)(dian)(dian)壓和電(dian)(dian)(dian)(dian)流(liu)，我(wo)(wo)們在使用的(de)(de)時候就(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充電器，電源適配器更(geng)要(yao)廣泛。因為但凡是電子(zi)產品，都會要(yao)用到開關電源。所以(yi)說(shuo)，開關電源的發展要(yao)更(geng)成(cheng)熟(shu)的多(duo)。經過這么多(duo)年經濟的發展，開關電源也不斷的進行創新，而(er)且從長遠來看，開關電源的發展前景是非常廣闊的。

總的來說，USB充電(dian)(dian)器它只(zhi)能(neng)用一根線連(lian)接來給(gei)設備進行充電(dian)(dian)，不(bu)能(neng)直接應(ying)用于設備上。但(dan)是(shi)電(dian)(dian)源(yuan)(yuan)適(shi)配(pei)器不(bu)僅能(neng)給(gei)電(dian)(dian)器充電(dian)(dian)，還(huan)可(ke)以直接在電(dian)(dian)源(yuan)(yuan)上應(ying)用，既能(neng)充電(dian)(dian)也能(neng)供電(dian)(dian)，而電(dian)(dian)源(yuan)(yuan)開關就(jiu)很(hen)好(hao)區別(bie)了，只(zhi)是(shi)一個開關的閥門而已。
