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(yuan)適配器(qi)的(de)(de)應用(yong)極為廣(guang)泛，日(ri)常(chang)生活用(yong)的(de)(de)電冰箱、洗(xi)衣機(ji)、空氣(qi)凈化器(qi)、家里的(de)(de)LED燈具和照明設備、數碼相機(ji)，座機(ji)電話、電腦(nao)、筆記本等。除(chu)了我們(men)日(ri)常(chang)的(de)(de)所(suo)(suo)見到的(de)(de)這(zhe)些(xie)東西以外(wai)，電源(yuan)適配器(qi)還應用(yong)在一些(xie)比(bi)較大的(de)(de)設備上面。比(bi)如(ru)說數控機(ji)床、工(gong)業(ye)自動化控制系統、電力設備和醫療設備上。在高校做(zuo)科研的(de)(de)時候所(suo)(suo)用(yong)的(de)(de)科研設備也有(you)涉及電源(yuan)適配器(qi)。

　　有(you)(you)很多人(ren)把(ba)電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器和電(dian)(dian)(dian)(dian)池的(de)(de)(de)(de)(de)作(zuo)用搞混(hun)了(le)(le)。其實(shi)這兩者是有(you)(you)著(zhu)本(ben)(ben)質區別的(de)(de)(de)(de)(de)。電(dian)(dian)(dian)(dian)池是用來(lai)儲備電(dian)(dian)(dian)(dian)量的(de)(de)(de)(de)(de)，而電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器是電(dian)(dian)(dian)(dian)源(yuan)到設備，到電(dian)(dian)(dian)(dian)池之間的(de)(de)(de)(de)(de)一(yi)(yi)個(ge)轉換(huan)系統。如果沒有(you)(you)電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器的(de)(de)(de)(de)(de)話，一(yi)(yi)旦電(dian)(dian)(dian)(dian)壓不穩，我(wo)們(men)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)腦、筆記本(ben)(ben)、電(dian)(dian)(dian)(dian)視等(deng)就(jiu)會被燒掉。所以說(shuo)(shuo)有(you)(you)了(le)(le)電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器對(dui)我(wo)們(men)的(de)(de)(de)(de)(de)家用電(dian)(dian)(dian)(dian)器來(lai)說(shuo)(shuo)是一(yi)(yi)個(ge)很好的(de)(de)(de)(de)(de)保(bao)護，同時也(ye)(ye)提高(gao)了(le)(le)電(dian)(dian)(dian)(dian)器的(de)(de)(de)(de)(de)安全性(xing)能。對(dui)我(wo)們(men)自身身體也(ye)(ye)起(qi)到保(bao)護，試(shi)想一(yi)(yi)下(xia)如果我(wo)們(men)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)器沒有(you)(you)電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器的(de)(de)(de)(de)(de)話，一(yi)(yi)旦電(dian)(dian)(dian)(dian)流過大(da)會突(tu)然中斷，就(jiu)有(you)(you)可能引起(qi)電(dian)(dian)(dian)(dian)器爆炸或者起(qi)火花等(deng)，造(zao)成(cheng)的(de)(de)(de)(de)(de)爆破或者火災，對(dui)我(wo)們(men)的(de)(de)(de)(de)(de)生命(ming)健康都有(you)(you)著(zhu)很大(da)的(de)(de)(de)(de)(de)威脅(xie)。可以說(shuo)(shuo)有(you)(you)了(le)(le)電(dian)(dian)(dian)(dian)源(yuan)適(shi)配器就(jiu)相當(dang)于給我(wo)們(men)的(de)(de)(de)(de)(de)家用電(dian)(dian)(dian)(dian)器上(shang)了(le)(le)保(bao)險。再也(ye)(ye)不用擔心那些意外事故了(le)(le)。
