電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配(pei)器(qi)(qi)又稱外置電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)，是一種小型便攜(xie)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備及電(dian)(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)變(bian)換(huan)設(she)備，由(you)外殼、變(bian)壓(ya)器(qi)(qi)、電(dian)(dian)(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)、控制IC、PCB板等元器(qi)(qi)件組成(cheng)，它的作(zuo)(zuo)用主要是：將(jiang)電(dian)(dian)(dian)(dian)(dian)(dian)流由(you)交流輸入轉換(huan)為直流輸出，把(ba)不穩定的電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)通過(guo)轉化電(dian)(dian)(dian)(dian)(dian)(dian)路變(bian)成(cheng)電(dian)(dian)(dian)(dian)(dian)(dian)子產品需要的恒壓(ya)直流電(dian)(dian)(dian)(dian)(dian)(dian)，從而給物體(ti)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)和(he)充電(dian)(dian)(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適配(pei)器(qi)(qi)可(ke)以看作(zuo)(zuo)是變(bian)壓(ya)器(qi)(qi)和(he)整流器(qi)(qi)，可(ke)以起到保護電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)和(he)人身安(an)全的作(zuo)(zuo)用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)(qi)并不是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)(qi)是電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)開(kai)關，用于提供(gong)電(dian)(dian)(dian)(dian)(dian)力能源(yuan)(yuan)，可以給投影儀、筆記本電(dian)(dian)(dian)(dian)(dian)腦、音響、凈水(shui)器(qi)(qi)(qi)(qi)等家(jia)用電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)子產品提供(gong)電(dian)(dian)(dian)(dian)(dian)力；而充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)是用來(lai)給電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)，一般會根據電(dian)(dian)(dian)(dian)(dian)池容量和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)特性進行(xing)分階(jie)段充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，二(er)者是不同的(de)。電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)的(de)區別(bie)還體(ti)現在(zai)定義、結構、電(dian)(dian)(dian)(dian)(dian)流模式、用途等方面，最(zui)大的(de)區別(bie)就(jiu)是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)只(zhi)是給電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)適配器(qi)(qi)(qi)(qi)不僅能給電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，還能給主(zhu)機供(gong)電(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情況下，電(dian)(dian)源(yuan)適(shi)配器(qi)(qi)能(neng)否通用(yong)要(yao)(yao)滿足三個(ge)條件(jian)：輸出電(dian)(dian)壓(ya)必須相同(tong)、輸出的(de)(de)(de)額定電(dian)(dian)流(liu)比原電(dian)(dian)器(qi)(qi)要(yao)(yao)求的(de)(de)(de)要(yao)(yao)大、接口相同(tong)，如果這三個(ge)方面都滿足的(de)(de)(de)話，可以臨(lin)時通用(yong)一下。不過需要(yao)(yao)注意的(de)(de)(de)是，部(bu)分電(dian)(dian)源(yuan)適(shi)配器(qi)(qi)也是不可以通用(yong)的(de)(de)(de)，通用(yong)可能(neng)會導致電(dian)(dian)器(qi)(qi)燒壞、無法使用(yong)等問(wen)題，因此如果原來的(de)(de)(de)電(dian)(dian)源(yuan)適(shi)配器(qi)(qi)損(sun)壞，建(jian)議還是聯系廠(chang)家購(gou)買(mai)一個(ge)原裝(zhuang)電(dian)(dian)源(yuan)適(shi)配器(qi)(qi)比較(jiao)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。
