是(shi)(shi)小(xiao)型(xing)(xing)便攜式(shi)電(dian)(dian)(dian)(dian)子(zi)設(she)備(bei)(bei)及電(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)器的供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)源(yuan)變換(huan)設(she)備(bei)(bei)，也是(shi)(shi)我們生活中最常(chang)見的電(dian)(dian)(dian)(dian)子(zi)設(she)備(bei)(bei)之一。一般由外(wai)殼(ke)、電(dian)(dian)(dian)(dian)源(yuan)變壓器和(he)整(zheng)流(liu)電(dian)(dian)(dian)(dian)路(lu)組(zu)成，按(an)其輸(shu)出(chu)類型(xing)(xing)可分(fen)為交流(liu)輸(shu)出(chu)型(xing)(xing)和(he)直流(liu)輸(shu)出(chu)型(xing)(xing)；按(an)連接方式(shi)可分(fen)為插(cha)墻(qiang)式(shi)和(he)桌(zhuo)面(mian)式(shi)。廣泛配(pei)套于手(shou)機、游戲機、平(ping)衡車、筆記本電(dian)(dian)(dian)(dian)腦、小(xiao)家電(dian)(dian)(dian)(dian)等設(she)備(bei)(bei)中。有關電(dian)(dian)(dian)(dian)源(yuan)適配(pei)器大家多少可能都有些了解，但是(shi)(shi)卻不全(quan)面(mian)。今天這里飛天鷹科技(ji)就為大家整(zheng)理一下。

電源適配器地作用：

      電源(yuan)適(shi)配器(qi)(qi)(qi)地(di)作(zuo)用就是(shi)(shi)(shi)變壓(ya)器(qi)(qi)(qi)和整流(liu)器(qi)(qi)(qi)。家用交流(liu)電是(shi)(shi)(shi)220v，而(er)(er)我們電腦用地(di)是(shi)(shi)(shi)直流(liu)12v（仿佛是(shi)(shi)(shi)），所(suo)以，能夠(gou)肯定電源(yuan)適(shi)配器(qi)(qi)(qi)就是(shi)(shi)(shi)變壓(ya)器(qi)(qi)(qi)兼整流(liu)器(qi)(qi)(qi)。那(nei)么適(shi)配器(qi)(qi)(qi)是(shi)(shi)(shi)變壓(ya)器(qi)(qi)(qi)，我們都應當(dang)知道，交流(liu)220v通(tong)(tong)(tong)過(guo)變壓(ya)器(qi)(qi)(qi)變壓(ya)，通(tong)(tong)(tong)過(guo)整流(liu)器(qi)(qi)(qi)變直流(liu)，這(zhe)里是(shi)(shi)(shi)有消(xiao)耗的(de)，而(er)(er)這(zhe)些消(xiao)耗就會轉變為熱量，所(suo)以電源(yuan)適(shi)配器(qi)(qi)(qi)會發熱也是(shi)(shi)(shi)正常的(de)。變壓(ya)器(qi)(qi)(qi)是(shi)(shi)(shi)硅(gui)鋼片做(zuo)成地(di)，變壓(ya)器(qi)(qi)(qi)通(tong)(tong)(tong)電后，產(chan)生磁通(tong)(tong)(tong)，磁通(tong)(tong)(tong)會招致硅(gui)鋼片間(jian)產(chan)生力地(di)作(zuo)用，從而(er)(er)產(chan)生嗡嗡聲音(yin)(yin)，這(zhe)是(shi)(shi)(shi)正常的(de)。但是(shi)(shi)(shi)過(guo)火大地(di)聲音(yin)(yin)就不正常了，緣由很多：1、交流(liu)電電壓(ya)不穩定。2、芯片破損(sun)(sun)。3、匝間(jian)短路。4、元件損(sun)(sun)壞。等等。

電源(yuan)適(shi)配器的應用：

      在消(xiao)費(fei)類電(dian)(dian)子產品(pin)中應用(yong)非常廣泛，提(ti)供的(de)輸出功率(lv)大多數都(dou)在100瓦以內(nei)，市場需(xu)求迅速增長。如電(dian)(dian)動自行車電(dian)(dian)池充電(dian)(dian)器(qi)、小尺寸液晶(jing)電(dian)(dian)視(shi)、筆記本(ben)(ben)電(dian)(dian)腦(nao)、打(da)印機(ji)(ji)、DVD播放器(qi)和機(ji)(ji)頂盒(he)等都(dou)有應用(yong)。早(zao)期的(de)電(dian)(dian)源(yuan)適(shi)配器(qi)大都(dou)選用(yong)線性變壓器(qi)，隨著(zhu)消(xiao)費(fei)類電(dian)(dian)子產品(pin)對(dui)電(dian)(dian)源(yuan)適(shi)配器(qi)有高效率(lv)、寬(kuan)輸入電(dian)(dian)壓范圍的(de)要求，以及銅(tong)、鐵和人力(li)成本(ben)(ben)的(de)增加，這類電(dian)(dian)源(yuan)適(shi)配器(qi)里面原(yuan)來的(de)線性變壓器(qi)大都(dou)逐漸被(bei)開(kai)關電(dian)(dian)源(yuan)取代(dai)。

電源適(shi)配器的(de)特性：

電(dian)(dian)(dian)(dian)(dian)(dian)源轉換(huan)器(qi)(qi)(qi)（既AC轉DC），由交流電(dian)(dian)(dian)(dian)(dian)(dian)轉換(huan)為直流電(dian)(dian)(dian)(dian)(dian)(dian)，再經過(guo)電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)，它是不能保護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)的，但電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)里面有儲存電(dian)(dian)(dian)(dian)(dian)(dian)源的儲存器(qi)(qi)(qi)（也叫充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)），所(suo)以在(zai)停電(dian)(dian)(dian)(dian)(dian)(dian)的時候(hou)可以保護(hu)電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)(nao)。開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)源與適配器(qi)(qi)(qi)都(dou)是開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)源，都(dou)由高頻開(kai)關管(guan)及其控制電(dian)(dian)(dian)(dian)(dian)(dian)路組成。適配器(qi)(qi)(qi)電(dian)(dian)(dian)(dian)(dian)(dian)源是一(yi)種穩(wen)壓開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)源，開(kai)關電(dian)(dian)(dian)(dian)(dian)(dian)源充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)是帶有浮(fu)充(chong)功能，電(dian)(dian)(dian)(dian)(dian)(dian)壓是隨電(dian)(dian)(dian)(dian)(dian)(dian)流的變小而變大，到(dao)最后是只有電(dian)(dian)(dian)(dian)(dian)(dian)壓而沒電(dian)(dian)(dian)(dian)(dian)(dian)流。
