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)器的(de)(de)應用(yong)極為廣泛(fan)，日常(chang)生活用(yong)的(de)(de)電(dian)冰箱、洗衣(yi)機、空氣(qi)凈化器、家里的(de)(de)LED燈具和照明設備(bei)、數(shu)碼相(xiang)機，座(zuo)機電(dian)話(hua)、電(dian)腦、筆(bi)記本等。除了我(wo)們日常(chang)的(de)(de)所見(jian)到(dao)的(de)(de)這(zhe)些東西(xi)以外，電(dian)源(yuan)適配(pei)器還應用(yong)在一些比較大(da)的(de)(de)設備(bei)上(shang)面(mian)。比如說(shuo)數(shu)控(kong)機床、工業自(zi)動化控(kong)制系(xi)統、電(dian)力設備(bei)和醫療設備(bei)上(shang)。在高校做科(ke)研(yan)(yan)的(de)(de)時(shi)候(hou)所用(yong)的(de)(de)科(ke)研(yan)(yan)設備(bei)也有(you)涉及電(dian)源(yuan)適配(pei)器。

　　有很(hen)多人(ren)把電(dian)(dian)(dian)源(yuan)適配(pei)器(qi)(qi)(qi)(qi)和電(dian)(dian)(dian)池的(de)(de)(de)作用(yong)搞(gao)混了(le)(le)。其實這(zhe)兩者(zhe)是(shi)有著本質區別的(de)(de)(de)。電(dian)(dian)(dian)池是(shi)用(yong)來儲備電(dian)(dian)(dian)量的(de)(de)(de)，而電(dian)(dian)(dian)源(yuan)適配(pei)器(qi)(qi)(qi)(qi)是(shi)電(dian)(dian)(dian)源(yuan)到設備，到電(dian)(dian)(dian)池之間的(de)(de)(de)一個轉換系(xi)統。如果沒(mei)有電(dian)(dian)(dian)源(yuan)適配(pei)器(qi)(qi)(qi)(qi)的(de)(de)(de)話，一旦(dan)電(dian)(dian)(dian)壓不穩，我(wo)(wo)們的(de)(de)(de)電(dian)(dian)(dian)腦、筆記本、電(dian)(dian)(dian)視等(deng)就(jiu)會被燒掉。所以(yi)(yi)說(shuo)有了(le)(le)電(dian)(dian)(dian)源(yuan)適配(pei)器(qi)(qi)(qi)(qi)對(dui)我(wo)(wo)們的(de)(de)(de)家用(yong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)來說(shuo)是(shi)一個很(hen)好(hao)的(de)(de)(de)保(bao)護，同時也(ye)提高了(le)(le)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)的(de)(de)(de)安(an)全性能(neng)。對(dui)我(wo)(wo)們自身身體也(ye)起到保(bao)護，試想一下如果我(wo)(wo)們的(de)(de)(de)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)沒(mei)有電(dian)(dian)(dian)源(yuan)適配(pei)器(qi)(qi)(qi)(qi)的(de)(de)(de)話，一旦(dan)電(dian)(dian)(dian)流過(guo)大(da)會突然中斷，就(jiu)有可能(neng)引起電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)爆炸或者(zhe)起火花等(deng)，造成(cheng)的(de)(de)(de)爆破或者(zhe)火災，對(dui)我(wo)(wo)們的(de)(de)(de)生命(ming)健康都有著很(hen)大(da)的(de)(de)(de)威(wei)脅。可以(yi)(yi)說(shuo)有了(le)(le)電(dian)(dian)(dian)源(yuan)適配(pei)器(qi)(qi)(qi)(qi)就(jiu)相當于給我(wo)(wo)們的(de)(de)(de)家用(yong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)上了(le)(le)保(bao)險。再(zai)也(ye)不用(yong)擔心(xin)那些(xie)意外(wai)事故了(le)(le)。
