電源適配器廣泛運用(yong)(yong)于工(gong)業生產機(ji)械(xie)自動化(hua)、軍用(yong)(yong)機(ji)器(qi)設(she)備(bei)(bei)、科學研究機(ji)器(qi)設(she)備(bei)(bei)、LED照(zhao)明燈具(ju)、工(gong)控自動化(hua)、通信設(she)備(bei)(bei)、電(dian)力工(gong)程、儀表設(she)備(bei)(bei)、醫療器(qi)械(xie)、半導體制冷(leng)制暖、空氣凈(jing)化(hua)機(ji)，電(dian)子冰箱，液晶顯示(shi)屏，LED照(zhao)明燈具(ju)，通信設(she)備(bei)(bei)，視(shi)聽產品(pin)，智能(neng)安防，電(dian)腦主(zhu)機(ji)，電(dian)子產品(pin)和儀器(qi)設(she)備(bei)(bei)類(lei)等行業，而且在這種行業都擁(yong)有不容忽視(shi)的作用(yong)(yong)。

　　那麼電源適配器的作用都都有哪些呢?

　　一般(ban)來說(shuo)(shuo)(shuo)，電(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)的作(zuo)用就(jiu)是(shi)(shi)說(shuo)(shuo)(shuo)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)和整流(liu)器(qi)(qi)(qi)。家(jia)庭裝交(jiao)流(liu)電(dian)(dian)(dian)是(shi)(shi)220v，而(er)人(ren)們(men)(men)電(dian)(dian)(dian)腦(nao)上商業(ye)用地(di)是(shi)(shi)直流(liu)電(dian)(dian)(dian)12v(好(hao)像(xiang)是(shi)(shi))，因(yin)此(ci)，可以毫無疑(yi)問(wen)電(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)就(jiu)是(shi)(shi)說(shuo)(shuo)(shuo)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)兼整流(liu)器(qi)(qi)(qi)。電(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)是(shi)(shi)變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)，那麼我們(men)(men)理應了解，溝通交(jiao)流(liu)220v根據變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)變(bian)(bian)壓(ya)(ya)(ya)，根據整流(liu)器(qi)(qi)(qi)變(bian)(bian)直流(liu)電(dian)(dian)(dian)，這兒(er)是(shi)(shi)有耗費(fei)的，而(er)這種耗費(fei)就(jiu)會變(bian)(bian)化為發熱量，因(yin)此(ci)電(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)會發燙(tang)都是(shi)(shi)一切正常(chang)的。變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)是(shi)(shi)硅(gui)鋼片制成(cheng)地(di)，變(bian)(bian)壓(ya)(ya)(ya)器(qi)(qi)(qi)接電(dian)(dian)(dian)源(yuan)(yuan)后，造成(cheng)磁(ci)通量，磁(ci)通量會導致(zhi)硅(gui)鋼片間造成(cheng)力地(di)作(zuo)用，進而(er)造成(cheng)嗡嗡響響聲，它是(shi)(shi)一切正常(chang)的。可是(shi)(shi)太過地(di)面響聲就(jiu)異常(chang)了，原因(yin)許多：交(jiao)流(liu)電(dian)(dian)(dian)工作(zuo)電(dian)(dian)(dian)壓(ya)(ya)(ya)不(bu)平(ping)穩;集(ji)成(cheng)ic損壞;堵轉(zhuan)短路(lu)故障;元器(qi)(qi)(qi)件毀(hui)壞這些。順(shun)帶說(shuo)(shuo)(shuo)一下(xia)，電(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)的作(zuo)用就(jiu)是(shi)(shi)說(shuo)(shuo)(shuo)將交(jiao)流(liu)電(dian)(dian)(dian)轉(zhuan)化成(cheng)交(jiao)流(liu)電(dian)(dian)(dian)的電(dian)(dian)(dian)子設備。
