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)(dian)(dian)源(yuan)適配(pei)器又稱外置電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)，是一種(zhong)小型便攜式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器的(de)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓變(bian)換設(she)備，由外殼、變(bian)壓器、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)感、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)容、控(kong)制(zhi)IC、PCB板等元器件(jian)組成，它的(de)作用主要(yao)是：將電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)由交流(liu)輸(shu)入轉(zhuan)換為直流(liu)輸(shu)出，把不穩定的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)通過轉(zhuan)化電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路變(bian)成電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品(pin)需要(yao)的(de)恒(heng)壓直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，從而給(gei)物體(ti)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)和(he)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適配(pei)器可以看作是變(bian)壓器和(he)整流(liu)器，可以起到保護電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器和(he)人(ren)身安全的(de)作用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)并不(bu)是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)是電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)開關，用(yong)(yong)(yong)(yong)于(yu)提供電(dian)(dian)(dian)(dian)(dian)力能(neng)(neng)源(yuan)(yuan)(yuan)，可(ke)以給(gei)(gei)投影儀、筆記本(ben)電(dian)(dian)(dian)(dian)(dian)腦(nao)、音(yin)響(xiang)、凈水器(qi)(qi)等家用(yong)(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)子產品提供電(dian)(dian)(dian)(dian)(dian)力；而(er)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是用(yong)(yong)(yong)(yong)來給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)的(de)，一般會根據(ju)電(dian)(dian)(dian)(dian)(dian)池容(rong)量和充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)特(te)性(xing)進行分階段充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，二者是不(bu)同(tong)的(de)。電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)區(qu)別還體現在定義、結(jie)構、電(dian)(dian)(dian)(dian)(dian)流模(mo)式、用(yong)(yong)(yong)(yong)途等方面，最大(da)的(de)區(qu)別就(jiu)是充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)器(qi)(qi)只(zhi)是給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)(dian)源(yuan)(yuan)(yuan)適(shi)配(pei)(pei)器(qi)(qi)不(bu)僅能(neng)(neng)給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)，還能(neng)(neng)給(gei)(gei)主機供電(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一(yi)般情況下，電源適配器(qi)能否(fou)通用(yong)(yong)要(yao)滿足(zu)三(san)個條件：輸出電壓必須相同(tong)、輸出的(de)額定電流比(bi)原(yuan)電器(qi)要(yao)求的(de)要(yao)大、接口相同(tong)，如果這三(san)個方(fang)面(mian)都滿足(zu)的(de)話，可(ke)以臨時通用(yong)(yong)一(yi)下。不過需要(yao)注意的(de)是(shi)(shi)，部(bu)分電源適配器(qi)也是(shi)(shi)不可(ke)以通用(yong)(yong)的(de)，通用(yong)(yong)可(ke)能會導致電器(qi)燒(shao)壞、無法使用(yong)(yong)等問題，因此(ci)如果原(yuan)來的(de)電源適配器(qi)損壞，建議還是(shi)(shi)聯系(xi)廠(chang)家購買一(yi)個原(yuan)裝(zhuang)電源適配器(qi)比(bi)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。
