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(yuan)適配(pei)器(qi)的(de)應用(yong)(yong)極(ji)為(wei)廣泛，日常(chang)生活用(yong)(yong)的(de)電(dian)冰箱、洗衣機、空氣凈化器(qi)、家里的(de)LED燈具和照明設備(bei)、數(shu)碼(ma)相機，座機電(dian)話、電(dian)腦、筆記本等。除了我們日常(chang)的(de)所見到的(de)這些東西以外，電(dian)源(yuan)適配(pei)器(qi)還應用(yong)(yong)在一些比(bi)較大的(de)設備(bei)上面。比(bi)如說數(shu)控機床(chuang)、工業(ye)自動化控制系統、電(dian)力設備(bei)和醫療設備(bei)上。在高校做科(ke)研的(de)時候所用(yong)(yong)的(de)科(ke)研設備(bei)也有涉及電(dian)源(yuan)適配(pei)器(qi)。

　　有(you)(you)(you)很(hen)多人把電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)作用(yong)搞混了(le)(le)。其實這(zhe)兩(liang)者是有(you)(you)(you)著本質區(qu)別(bie)的(de)(de)(de)。電(dian)(dian)(dian)(dian)池(chi)是用(yong)來儲(chu)備電(dian)(dian)(dian)(dian)量(liang)的(de)(de)(de)，而電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)是電(dian)(dian)(dian)(dian)源(yuan)到設備，到電(dian)(dian)(dian)(dian)池(chi)之間的(de)(de)(de)一(yi)個轉換系(xi)統。如(ru)果沒有(you)(you)(you)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)的(de)(de)(de)話(hua)，一(yi)旦電(dian)(dian)(dian)(dian)壓不穩(wen)，我(wo)(wo)(wo)們(men)(men)(men)的(de)(de)(de)電(dian)(dian)(dian)(dian)腦、筆記本、電(dian)(dian)(dian)(dian)視等就會被燒掉(diao)。所以說(shuo)有(you)(you)(you)了(le)(le)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)對(dui)我(wo)(wo)(wo)們(men)(men)(men)的(de)(de)(de)家(jia)(jia)用(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)來說(shuo)是一(yi)個很(hen)好的(de)(de)(de)保護，同時也提高(gao)了(le)(le)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)的(de)(de)(de)安全(quan)性能(neng)(neng)。對(dui)我(wo)(wo)(wo)們(men)(men)(men)自身身體也起(qi)到保護，試想一(yi)下如(ru)果我(wo)(wo)(wo)們(men)(men)(men)的(de)(de)(de)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)沒有(you)(you)(you)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)的(de)(de)(de)話(hua)，一(yi)旦電(dian)(dian)(dian)(dian)流過大(da)會突然(ran)中斷(duan)，就有(you)(you)(you)可(ke)能(neng)(neng)引起(qi)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)爆炸或者起(qi)火花等，造成(cheng)的(de)(de)(de)爆破(po)或者火災，對(dui)我(wo)(wo)(wo)們(men)(men)(men)的(de)(de)(de)生命健康都(dou)有(you)(you)(you)著很(hen)大(da)的(de)(de)(de)威(wei)脅。可(ke)以說(shuo)有(you)(you)(you)了(le)(le)電(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)(pei)器(qi)(qi)(qi)就相當(dang)于(yu)給我(wo)(wo)(wo)們(men)(men)(men)的(de)(de)(de)家(jia)(jia)用(yong)電(dian)(dian)(dian)(dian)器(qi)(qi)(qi)上(shang)了(le)(le)保險(xian)。再也不用(yong)擔心那(nei)些意外事故了(le)(le)。
