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(dian)源適(shi)配器的(de)(de)應(ying)用(yong)(yong)(yong)極為廣泛，日常生活用(yong)(yong)(yong)的(de)(de)電(dian)冰箱、洗(xi)衣機(ji)、空(kong)氣凈化(hua)器、家里的(de)(de)LED燈具和照明設備、數(shu)碼相機(ji)，座機(ji)電(dian)話、電(dian)腦、筆記本(ben)等。除了我們(men)日常的(de)(de)所見到的(de)(de)這些東(dong)西(xi)以外，電(dian)源適(shi)配器還應(ying)用(yong)(yong)(yong)在(zai)一些比較大的(de)(de)設備上(shang)面(mian)。比如說數(shu)控(kong)機(ji)床(chuang)、工業自動化(hua)控(kong)制系統、電(dian)力設備和醫療設備上(shang)。在(zai)高校做科(ke)研的(de)(de)時(shi)候所用(yong)(yong)(yong)的(de)(de)科(ke)研設備也有涉及電(dian)源適(shi)配器。

　　有(you)(you)很多人把(ba)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)(de)(de)作用(yong)(yong)搞(gao)混了(le)。其實這(zhe)兩者(zhe)(zhe)是有(you)(you)著(zhu)本質區別的(de)(de)(de)。電(dian)(dian)(dian)(dian)(dian)(dian)池是用(yong)(yong)來(lai)儲備(bei)電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)的(de)(de)(de)，而電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器(qi)(qi)是電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)到(dao)設備(bei)，到(dao)電(dian)(dian)(dian)(dian)(dian)(dian)池之間的(de)(de)(de)一個轉換系統。如(ru)果沒(mei)有(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器(qi)(qi)的(de)(de)(de)話，一旦電(dian)(dian)(dian)(dian)(dian)(dian)壓不(bu)穩，我們(men)(men)(men)(men)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)腦、筆(bi)記本、電(dian)(dian)(dian)(dian)(dian)(dian)視等就(jiu)會被燒掉(diao)。所以說有(you)(you)了(le)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器(qi)(qi)對(dui)我們(men)(men)(men)(men)的(de)(de)(de)家用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)來(lai)說是一個很好的(de)(de)(de)保護，同時也提高了(le)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)(de)安全性能。對(dui)我們(men)(men)(men)(men)自(zi)身(shen)身(shen)體也起到(dao)保護，試想一下如(ru)果我們(men)(men)(men)(men)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)沒(mei)有(you)(you)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器(qi)(qi)的(de)(de)(de)話，一旦電(dian)(dian)(dian)(dian)(dian)(dian)流過大(da)會突然中(zhong)斷，就(jiu)有(you)(you)可能引起電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)爆炸或(huo)者(zhe)(zhe)起火(huo)(huo)花等，造成的(de)(de)(de)爆破或(huo)者(zhe)(zhe)火(huo)(huo)災，對(dui)我們(men)(men)(men)(men)的(de)(de)(de)生命健康都(dou)有(you)(you)著(zhu)很大(da)的(de)(de)(de)威(wei)脅(xie)。可以說有(you)(you)了(le)電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配器(qi)(qi)就(jiu)相當于(yu)給我們(men)(men)(men)(men)的(de)(de)(de)家用(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)上(shang)了(le)保險。再也不(bu)用(yong)(yong)擔心那些意(yi)外事故了(le)。
