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)(dian)源適配(pei)器的(de)(de)應(ying)用(yong)(yong)極為廣泛，日(ri)(ri)常(chang)生(sheng)活用(yong)(yong)的(de)(de)電(dian)(dian)冰(bing)箱、洗衣機(ji)(ji)(ji)、空氣凈化器、家里(li)的(de)(de)LED燈具(ju)和照明設(she)(she)備(bei)、數碼相機(ji)(ji)(ji)，座機(ji)(ji)(ji)電(dian)(dian)話、電(dian)(dian)腦、筆記本等。除了(le)我們日(ri)(ri)常(chang)的(de)(de)所見到(dao)的(de)(de)這些(xie)東西以外，電(dian)(dian)源適配(pei)器還(huan)應(ying)用(yong)(yong)在一些(xie)比(bi)較大的(de)(de)設(she)(she)備(bei)上面(mian)。比(bi)如說數控(kong)機(ji)(ji)(ji)床、工業自動化控(kong)制系統、電(dian)(dian)力設(she)(she)備(bei)和醫(yi)療(liao)設(she)(she)備(bei)上。在高校(xiao)做科(ke)研的(de)(de)時候所用(yong)(yong)的(de)(de)科(ke)研設(she)(she)備(bei)也有涉(she)及電(dian)(dian)源適配(pei)器。

　　有(you)很多人把電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)(de)作用搞混(hun)了(le)。其實這兩者(zhe)是有(you)著本(ben)質(zhi)區別的(de)(de)(de)(de)。電(dian)(dian)(dian)(dian)池(chi)是用來儲備(bei)電(dian)(dian)(dian)(dian)量的(de)(de)(de)(de)，而電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)是電(dian)(dian)(dian)(dian)源(yuan)到(dao)設備(bei)，到(dao)電(dian)(dian)(dian)(dian)池(chi)之間的(de)(de)(de)(de)一(yi)(yi)個(ge)轉換系統。如(ru)果(guo)沒有(you)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)的(de)(de)(de)(de)話，一(yi)(yi)旦(dan)(dan)電(dian)(dian)(dian)(dian)壓(ya)不(bu)穩，我(wo)們(men)(men)(men)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)腦、筆記本(ben)、電(dian)(dian)(dian)(dian)視等(deng)就會(hui)被燒掉。所以(yi)說(shuo)有(you)了(le)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)對我(wo)們(men)(men)(men)的(de)(de)(de)(de)家用電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)來說(shuo)是一(yi)(yi)個(ge)很好的(de)(de)(de)(de)保(bao)護，同時也提高了(le)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)(de)安全性(xing)能。對我(wo)們(men)(men)(men)自身身體也起到(dao)保(bao)護，試(shi)想一(yi)(yi)下如(ru)果(guo)我(wo)們(men)(men)(men)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)沒有(you)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)的(de)(de)(de)(de)話，一(yi)(yi)旦(dan)(dan)電(dian)(dian)(dian)(dian)流過大(da)會(hui)突然中斷，就有(you)可(ke)能引起電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)爆炸或者(zhe)起火花(hua)等(deng)，造(zao)成的(de)(de)(de)(de)爆破(po)或者(zhe)火災，對我(wo)們(men)(men)(men)的(de)(de)(de)(de)生命健康都有(you)著很大(da)的(de)(de)(de)(de)威脅。可(ke)以(yi)說(shuo)有(you)了(le)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)(qi)就相當于(yu)給(gei)我(wo)們(men)(men)(men)的(de)(de)(de)(de)家用電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)上了(le)保(bao)險。再(zai)也不(bu)用擔心(xin)那些意外事故了(le)。
