電源適配器廣泛運用(yong)于(yu)工業(ye)(ye)生產機械自動(dong)化(hua)、軍用(yong)機器設(she)(she)備(bei)、科(ke)學研究機器設(she)(she)備(bei)、LED照明燈(deng)(deng)具(ju)、工控自動(dong)化(hua)、通(tong)信設(she)(she)備(bei)、電(dian)力工程、儀(yi)表設(she)(she)備(bei)、醫(yi)療(liao)器械、半導(dao)體制冷(leng)制暖、空氣凈(jing)化(hua)機，電(dian)子冰箱，液晶(jing)顯示(shi)屏，LED照明燈(deng)(deng)具(ju)，通(tong)信設(she)(she)備(bei)，視(shi)聽產品(pin)，智能(neng)安防，電(dian)腦(nao)主機，電(dian)子產品(pin)和儀(yi)器設(she)(she)備(bei)類等行(xing)業(ye)(ye)，而且在這種(zhong)行(xing)業(ye)(ye)都擁有不容忽視(shi)的作用(yong)。

　　那麼電源適配器的作用都都有哪些呢?

　　一(yi)般(ban)來(lai)說，電(dian)(dian)源適(shi)配器(qi)的(de)作(zuo)用(yong)就是(shi)(shi)(shi)說變(bian)壓(ya)器(qi)和整流(liu)(liu)(liu)(liu)器(qi)。家庭裝交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)是(shi)(shi)(shi)220v，而(er)人(ren)們電(dian)(dian)腦上(shang)商業用(yong)地是(shi)(shi)(shi)直(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)12v(好像(xiang)是(shi)(shi)(shi))，因此，可以毫(hao)無疑問(wen)電(dian)(dian)源適(shi)配器(qi)就是(shi)(shi)(shi)說變(bian)壓(ya)器(qi)兼整流(liu)(liu)(liu)(liu)器(qi)。電(dian)(dian)源適(shi)配器(qi)是(shi)(shi)(shi)變(bian)壓(ya)器(qi)，那麼我們理應了解，溝通交(jiao)流(liu)(liu)(liu)(liu)220v根據變(bian)壓(ya)器(qi)變(bian)壓(ya)，根據整流(liu)(liu)(liu)(liu)器(qi)變(bian)直(zhi)流(liu)(liu)(liu)(liu)電(dian)(dian)，這(zhe)兒是(shi)(shi)(shi)有耗(hao)(hao)費的(de)，而(er)這(zhe)種耗(hao)(hao)費就會(hui)(hui)變(bian)化(hua)為發熱量(liang)，因此電(dian)(dian)源適(shi)配器(qi)會(hui)(hui)發燙都是(shi)(shi)(shi)一(yi)切正(zheng)常的(de)。變(bian)壓(ya)器(qi)是(shi)(shi)(shi)硅鋼片制成(cheng)(cheng)(cheng)地，變(bian)壓(ya)器(qi)接電(dian)(dian)源后，造(zao)(zao)成(cheng)(cheng)(cheng)磁(ci)通量(liang)，磁(ci)通量(liang)會(hui)(hui)導致硅鋼片間(jian)造(zao)(zao)成(cheng)(cheng)(cheng)力地作(zuo)用(yong)，進而(er)造(zao)(zao)成(cheng)(cheng)(cheng)嗡(weng)嗡(weng)響(xiang)響(xiang)聲，它是(shi)(shi)(shi)一(yi)切正(zheng)常的(de)。可是(shi)(shi)(shi)太過(guo)地面響(xiang)聲就異常了，原因許多(duo)：交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)工作(zuo)電(dian)(dian)壓(ya)不平穩;集(ji)成(cheng)(cheng)(cheng)ic損壞;堵轉短(duan)路故障;元器(qi)件毀壞這(zhe)些。順帶說一(yi)下，電(dian)(dian)源適(shi)配器(qi)的(de)作(zuo)用(yong)就是(shi)(shi)(shi)說將交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)轉化(hua)成(cheng)(cheng)(cheng)交(jiao)流(liu)(liu)(liu)(liu)電(dian)(dian)的(de)電(dian)(dian)子設備(bei)。
