隨著人類的進步，科技的發展。現每個的家庭中都有或大或小的電器，當然也離不開電源適配器輔助設備。

　　電源適配器的(de)(de)(de)應用極為廣泛，日常生活用的(de)(de)(de)電冰(bing)箱、洗衣機(ji)、空氣凈(jing)化器、家里的(de)(de)(de)LED燈具和照明設(she)備(bei)(bei)、數碼相機(ji)，座機(ji)電話、電腦、筆記本(ben)等。除了(le)我們日常的(de)(de)(de)所見到(dao)的(de)(de)(de)這些東西(xi)以外，電源適配器還應用在一(yi)些比(bi)較大的(de)(de)(de)設(she)備(bei)(bei)上(shang)面。比(bi)如說數控機(ji)床、工(gong)業自動化控制(zhi)系統(tong)、電力設(she)備(bei)(bei)和醫(yi)療設(she)備(bei)(bei)上(shang)。在高(gao)校做(zuo)科(ke)研的(de)(de)(de)時候所用的(de)(de)(de)科(ke)研設(she)備(bei)(bei)也有涉及電源適配器。

　　有(you)(you)(you)(you)很多人把電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)(de)作(zuo)用搞(gao)混了(le)(le)。其實這兩者是(shi)有(you)(you)(you)(you)著本(ben)質區別的(de)(de)(de)(de)(de)。電(dian)(dian)(dian)(dian)(dian)池是(shi)用來儲(chu)備電(dian)(dian)(dian)(dian)(dian)量(liang)的(de)(de)(de)(de)(de)，而電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)是(shi)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)到設備，到電(dian)(dian)(dian)(dian)(dian)池之間的(de)(de)(de)(de)(de)一個(ge)轉換系統。如果(guo)沒有(you)(you)(you)(you)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)的(de)(de)(de)(de)(de)話，一旦電(dian)(dian)(dian)(dian)(dian)壓不(bu)(bu)穩(wen)，我們(men)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)腦(nao)、筆記本(ben)、電(dian)(dian)(dian)(dian)(dian)視等(deng)就會被燒(shao)掉。所以說有(you)(you)(you)(you)了(le)(le)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)對(dui)我們(men)的(de)(de)(de)(de)(de)家(jia)用電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)來說是(shi)一個(ge)很好的(de)(de)(de)(de)(de)保(bao)護(hu)，同時也(ye)提(ti)高(gao)了(le)(le)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)(de)(de)安全性能。對(dui)我們(men)自身(shen)身(shen)體也(ye)起到保(bao)護(hu)，試想(xiang)一下如果(guo)我們(men)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)沒有(you)(you)(you)(you)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)的(de)(de)(de)(de)(de)話，一旦電(dian)(dian)(dian)(dian)(dian)流過(guo)大會突然(ran)中斷，就有(you)(you)(you)(you)可(ke)能引起電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)爆炸或者起火花等(deng)，造成的(de)(de)(de)(de)(de)爆破(po)或者火災，對(dui)我們(men)的(de)(de)(de)(de)(de)生命(ming)健康都有(you)(you)(you)(you)著很大的(de)(de)(de)(de)(de)威(wei)脅。可(ke)以說有(you)(you)(you)(you)了(le)(le)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)就相當于給我們(men)的(de)(de)(de)(de)(de)家(jia)用電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)上了(le)(le)保(bao)險。再(zai)也(ye)不(bu)(bu)用擔心(xin)那些意(yi)外(wai)事故了(le)(le)。
