電源適配器廣泛(fan)運(yun)用(yong)于工業(ye)生產(chan)機械(xie)自動(dong)化、軍用(yong)機器(qi)(qi)設備、科學研究機器(qi)(qi)設備、LED照明燈具、工控自動(dong)化、通(tong)信設備、電(dian)力工程、儀(yi)表設備、醫療器(qi)(qi)械(xie)、半導體制冷制暖、空(kong)氣凈化機，電(dian)子(zi)(zi)冰箱，液晶顯示屏(ping)，LED照明燈具，通(tong)信設備，視聽產(chan)品，智能安防，電(dian)腦主機，電(dian)子(zi)(zi)產(chan)品和儀(yi)器(qi)(qi)設備類(lei)等行業(ye)，而(er)且在這種(zhong)行業(ye)都擁有不容忽視的作(zuo)用(yong)。

　　那麼電源適配器的作用都都有哪些呢?

　　一般來說(shuo)(shuo)(shuo)，電(dian)(dian)源(yuan)適配(pei)器(qi)(qi)的(de)作(zuo)用(yong)就(jiu)(jiu)(jiu)是(shi)(shi)(shi)(shi)說(shuo)(shuo)(shuo)變壓器(qi)(qi)和整流(liu)器(qi)(qi)。家庭裝(zhuang)交流(liu)電(dian)(dian)是(shi)(shi)(shi)(shi)220v，而人們電(dian)(dian)腦上商業用(yong)地(di)是(shi)(shi)(shi)(shi)直流(liu)電(dian)(dian)12v(好像(xiang)是(shi)(shi)(shi)(shi))，因此(ci)(ci)，可以毫無疑問電(dian)(dian)源(yuan)適配(pei)器(qi)(qi)就(jiu)(jiu)(jiu)是(shi)(shi)(shi)(shi)說(shuo)(shuo)(shuo)變壓器(qi)(qi)兼整流(liu)器(qi)(qi)。電(dian)(dian)源(yuan)適配(pei)器(qi)(qi)是(shi)(shi)(shi)(shi)變壓器(qi)(qi)，那(nei)麼(ma)我們理應了解(jie)，溝(gou)通(tong)(tong)交流(liu)220v根據變壓器(qi)(qi)變壓，根據整流(liu)器(qi)(qi)變直流(liu)電(dian)(dian)，這兒(er)是(shi)(shi)(shi)(shi)有(you)耗費的(de)，而這種耗費就(jiu)(jiu)(jiu)會變化為發熱量，因此(ci)(ci)電(dian)(dian)源(yuan)適配(pei)器(qi)(qi)會發燙都是(shi)(shi)(shi)(shi)一切正常的(de)。變壓器(qi)(qi)是(shi)(shi)(shi)(shi)硅(gui)鋼片制(zhi)成(cheng)(cheng)地(di)，變壓器(qi)(qi)接電(dian)(dian)源(yuan)后(hou)，造(zao)成(cheng)(cheng)磁(ci)通(tong)(tong)量，磁(ci)通(tong)(tong)量會導致硅(gui)鋼片間(jian)造(zao)成(cheng)(cheng)力(li)地(di)作(zuo)用(yong)，進而造(zao)成(cheng)(cheng)嗡嗡響響聲(sheng)，它是(shi)(shi)(shi)(shi)一切正常的(de)。可是(shi)(shi)(shi)(shi)太(tai)過地(di)面響聲(sheng)就(jiu)(jiu)(jiu)異常了，原(yuan)因許多：交流(liu)電(dian)(dian)工作(zuo)電(dian)(dian)壓不平穩(wen);集成(cheng)(cheng)ic損(sun)壞;堵轉短路故障(zhang);元器(qi)(qi)件毀壞這些。順帶說(shuo)(shuo)(shuo)一下，電(dian)(dian)源(yuan)適配(pei)器(qi)(qi)的(de)作(zuo)用(yong)就(jiu)(jiu)(jiu)是(shi)(shi)(shi)(shi)說(shuo)(shuo)(shuo)將交流(liu)電(dian)(dian)轉化成(cheng)(cheng)交流(liu)電(dian)(dian)的(de)電(dian)(dian)子(zi)設備。
