電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)又稱外置(zhi)電(dian)(dian)(dian)(dian)源(yuan)(yuan)，是(shi)一種小型便攜式電(dian)(dian)(dian)(dian)子(zi)設(she)備及電(dian)(dian)(dian)(dian)子(zi)電(dian)(dian)(dian)(dian)器(qi)(qi)的(de)供電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓(ya)變換設(she)備，由外殼(ke)、變壓(ya)器(qi)(qi)、電(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)容、控制(zhi)IC、PCB板等元器(qi)(qi)件(jian)組成，它的(de)作用(yong)主(zhu)要是(shi)：將電(dian)(dian)(dian)(dian)流(liu)(liu)由交流(liu)(liu)輸入轉(zhuan)換為直流(liu)(liu)輸出，把不穩(wen)定的(de)電(dian)(dian)(dian)(dian)源(yuan)(yuan)通過轉(zhuan)化電(dian)(dian)(dian)(dian)路變成電(dian)(dian)(dian)(dian)子(zi)產品需要的(de)恒(heng)壓(ya)直流(liu)(liu)電(dian)(dian)(dian)(dian)，從而給物體供電(dian)(dian)(dian)(dian)和(he)充電(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)源(yuan)(yuan)適配(pei)器(qi)(qi)可以(yi)看作是(shi)變壓(ya)器(qi)(qi)和(he)整流(liu)(liu)器(qi)(qi)，可以(yi)起到保護電(dian)(dian)(dian)(dian)器(qi)(qi)和(he)人身安全(quan)的(de)作用(yong)。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)(qi)(qi)并不(bu)是充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，電(dian)(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)(qi)(qi)是電(dian)(dian)(dian)源開(kai)關，用(yong)于提供(gong)(gong)(gong)電(dian)(dian)(dian)力(li)能(neng)源，可以給(gei)(gei)(gei)投影儀、筆(bi)記本電(dian)(dian)(dian)腦(nao)、音(yin)響、凈水(shui)器(qi)(qi)(qi)(qi)(qi)等家用(yong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)或電(dian)(dian)(dian)子產品提供(gong)(gong)(gong)電(dian)(dian)(dian)力(li)；而(er)充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)是用(yong)來給(gei)(gei)(gei)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)的(de)，一(yi)般會(hui)根(gen)據電(dian)(dian)(dian)池容量和充(chong)電(dian)(dian)(dian)特性進(jin)行分階段充(chong)電(dian)(dian)(dian)，二者是不(bu)同的(de)。電(dian)(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)(qi)(qi)和電(dian)(dian)(dian)源充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)區別還體現在定義、結構、電(dian)(dian)(dian)流(liu)模(mo)式、用(yong)途等方面，最(zui)大的(de)區別就(jiu)是充(chong)電(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)只是給(gei)(gei)(gei)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)源適(shi)配(pei)器(qi)(qi)(qi)(qi)(qi)不(bu)僅能(neng)給(gei)(gei)(gei)電(dian)(dian)(dian)池充(chong)電(dian)(dian)(dian)，還能(neng)給(gei)(gei)(gei)主機(ji)供(gong)(gong)(gong)電(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一(yi)般情況下，電(dian)源(yuan)適配(pei)(pei)器(qi)能否通用要(yao)(yao)(yao)滿(man)(man)足(zu)(zu)三個條件：輸出電(dian)壓必須相(xiang)(xiang)同、輸出的額定電(dian)流比原(yuan)(yuan)電(dian)器(qi)要(yao)(yao)(yao)求的要(yao)(yao)(yao)大、接(jie)口相(xiang)(xiang)同，如(ru)果(guo)這三個方面都滿(man)(man)足(zu)(zu)的話，可(ke)以(yi)臨(lin)時通用一(yi)下。不(bu)過需(xu)要(yao)(yao)(yao)注意的是(shi)(shi)(shi)，部分(fen)電(dian)源(yuan)適配(pei)(pei)器(qi)也是(shi)(shi)(shi)不(bu)可(ke)以(yi)通用的，通用可(ke)能會導(dao)致電(dian)器(qi)燒壞(huai)、無(wu)法使(shi)用等問題，因此(ci)如(ru)果(guo)原(yuan)(yuan)來的電(dian)源(yuan)適配(pei)(pei)器(qi)損壞(huai)，建議還(huan)是(shi)(shi)(shi)聯系廠家購買一(yi)個原(yuan)(yuan)裝(zhuang)電(dian)源(yuan)適配(pei)(pei)器(qi)比較好。

四、電源適配器多少錢一個

電源適配器的價格并不高，根據輸入電壓大小、輸入電流類型、供電方式、電源安數等有所不同，價格大概在二十多元到四五十元左右，也有部分電源適配器產品可能會更貴一些。需要注意的是，電源適配器市場比較混亂，有一些比較便宜的電源適配器甚至只要幾塊錢，這種可能是以次充好、以舊充新的產品，不建議購買，要選擇正規優質的電源適配器品牌廠家購買產品。
