隨(sui)著科技的(de)發展，人(ren)類社(she)會的(de)進步，現在(zai)的(de)電子(zi)(zi)產(chan)(chan)品(pin)特(te)別的(de)多(duo)(duo)，而(er)且(qie)占了(le)我(wo)(wo)們(men)生(sheng)活的(de)主(zhu)力面。由于電子(zi)(zi)產(chan)(chan)品(pin)種類繁多(duo)(duo)，用途(tu)也(ye)各不相同。所以(yi)說(shuo)大多(duo)(duo)數(shu)人(ren)并不知道(dao)這些電子(zi)(zi)產(chan)(chan)品(pin)中(zhong)(zhong)間的(de)區別。今天我(wo)(wo)們(men)就(jiu)來(lai)看一下我(wo)(wo)們(men)日常生(sheng)活中(zhong)(zhong)最常見(jian)的(de)三個電子(zi)(zi)產(chan)(chan)品(pin)，電源(yuan)適配器(qi)，開(kai)關(guan)電源(yuan)，充電器之(zhi)間的(de)區別。

一、充電器

首先我們要說的就是USB充(chong)(chong)(chong)電(dian)器。這可(ke)能也(ye)是大家最了解的(de)(de)(de)一(yi)(yi)種(zhong)了，因為(wei)不(bu)管是我們的(de)(de)(de)手機(ji)還是相機(ji)，基本都要用(yong)到充(chong)(chong)(chong)電(dian)器。但是大家可(ke)能也(ye)只是了解了它(ta)表面的(de)(de)(de)東西(xi)。用(yong)書面語言來說(shuo)，充(chong)(chong)(chong)電(dian)器屬于一(yi)(yi)種(zhong)電(dian)器的(de)(de)(de)附件。是一(yi)(yi)種(zhong)電(dian)子半(ban)導體，也(ye)可(ke)以(yi)說(shuo)是一(yi)(yi)種(zhong)電(dian)流(liu)變(bian)換(huan)器，將(jiang)交流(liu)電(dian)變(bian)成直流(liu)電(dian)來供設(she)備(bei)使用(yong)。手機(ji)相機(ji)之類的(de)(de)(de)設(she)備(bei)一(yi)(yi)直在發展，那(nei)么充(chong)(chong)(chong)電(dian)器作為(wei)附屬電(dian)器也(ye)將(jiang)有很(hen)好(hao)的(de)(de)(de)發展和應用(yong)的(de)(de)(de)前景。

二、電源適配器

對于(yu)電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)可能大部分人不是(shi)(shi)(shi)很了(le)解。簡單點(dian)來說電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)就(jiu)是(shi)(shi)(shi)一種(zhong)電(dian)(dian)(dian)源(yuan)(yuan)的(de)(de)變換設備。一般(ban)體積比較的(de)(de)小。但(dan)是(shi)(shi)(shi)電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)的(de)(de)種(zhong)類(lei)也是(shi)(shi)(shi)多種(zhong)多樣的(de)(de)。比如(ru)直流輸(shu)出型和(he)交流輸(shu)出型的(de)(de)電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)。連接方式也是(shi)(shi)(shi)多種(zhong)多樣的(de)(de)，有(you)(you)(you)的(de)(de)是(shi)(shi)(shi)插在墻上(shang)(shang)的(de)(de)，有(you)(you)(you)的(de)(de)是(shi)(shi)(shi)桌面式的(de)(de)。除了(le)這些，電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)的(de)(de)應用(yong)就(jiu)更廣泛了(le)，不管是(shi)(shi)(shi)筆記本電(dian)(dian)(dian)腦(nao)，還是(shi)(shi)(shi)電(dian)(dian)(dian)話子(zi)(zi)母機(ji)，小孩子(zi)(zi)用(yong)的(de)(de)復(fu)讀機(ji)，游(you)戲機(ji)還是(shi)(shi)(shi)我們聽(ting)歌用(yong)的(de)(de)隨身聽(ting)，都有(you)(you)(you)應用(yong)到電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)。而且電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)發展的(de)(de)已經(jing)比較成熟了(le)，一般(ban)的(de)(de)電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)都是(shi)(shi)(shi)具有(you)(you)(you)自動檢(jian)測(ce)功能的(de)(de)。而且，電(dian)(dian)(dian)源(yuan)(yuan)適(shi)(shi)配(pei)器(qi)(qi)上(shang)(shang)面都標有(you)(you)(you)電(dian)(dian)(dian)壓和(he)電(dian)(dian)(dian)流，我們在使用(yong)的(de)(de)時(shi)候就(jiu)有(you)(you)(you)個參(can)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(dian)器(qi)，電(dian)源適(shi)配器(qi)更要廣(guang)泛。因為(wei)但凡是(shi)電(dian)子產品，都會要用(yong)到開(kai)關(guan)(guan)電(dian)源。所以說，開(kai)關(guan)(guan)電(dian)源的(de)發(fa)展(zhan)要更成熟的(de)多。經過這么多年經濟(ji)的(de)發(fa)展(zhan)，開(kai)關(guan)(guan)電(dian)源也(ye)不斷的(de)進行(xing)創新(xin)，而且從長遠來看，開(kai)關(guan)(guan)電(dian)源的(de)發(fa)展(zhan)前景是(shi)非(fei)常廣(guang)闊(kuo)的(de)。

總的來說，USB充電(dian)(dian)(dian)(dian)器(qi)(qi)它(ta)只(zhi)能用一(yi)根線(xian)連接(jie)(jie)來給設(she)備進行(xing)充電(dian)(dian)(dian)(dian)，不能直接(jie)(jie)應用于設(she)備上。但是(shi)電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)不僅能給電(dian)(dian)(dian)(dian)器(qi)(qi)充電(dian)(dian)(dian)(dian)，還(huan)可以直接(jie)(jie)在電(dian)(dian)(dian)(dian)源(yuan)上應用，既能充電(dian)(dian)(dian)(dian)也能供電(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)源(yuan)開關就很好區別了，只(zhi)是(shi)一(yi)個開關的(de)閥門而(er)已(yi)。
