電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)源(yuan)適配器又(you)稱(cheng)外置電(dian)(dian)源(yuan)，是一種小型便(bian)攜式(shi)電(dian)(dian)子設(she)備(bei)及電(dian)(dian)子電(dian)(dian)器的(de)供(gong)電(dian)(dian)電(dian)(dian)壓(ya)(ya)變(bian)換設(she)備(bei)，由外殼、變(bian)壓(ya)(ya)器、電(dian)(dian)感、電(dian)(dian)容(rong)、控(kong)制(zhi)IC、PCB板等(deng)元器件組成，它的(de)作用主要是：將電(dian)(dian)流(liu)由交流(liu)輸(shu)入(ru)轉(zhuan)換為直流(liu)輸(shu)出，把不穩定的(de)電(dian)(dian)源(yuan)通過轉(zhuan)化(hua)電(dian)(dian)路變(bian)成電(dian)(dian)子產(chan)品需要的(de)恒(heng)壓(ya)(ya)直流(liu)電(dian)(dian)，從而給(gei)物(wu)體供(gong)電(dian)(dian)和充(chong)電(dian)(dian)。電(dian)(dian)源(yuan)適配器可以看作是變(bian)壓(ya)(ya)器和整流(liu)器，可以起到保(bao)護電(dian)(dian)器和人身(shen)安全的(de)作用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)源適配(pei)器(qi)并(bing)不是(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)源適配(pei)器(qi)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)源開關，用于提(ti)供電(dian)(dian)(dian)(dian)(dian)(dian)力(li)能(neng)源，可(ke)以給(gei)投影儀、筆(bi)記本(ben)電(dian)(dian)(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)等(deng)(deng)家(jia)用電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)或(huo)電(dian)(dian)(dian)(dian)(dian)(dian)子產品(pin)提(ti)供電(dian)(dian)(dian)(dian)(dian)(dian)力(li)；而充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)是(shi)用來給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)的，一般會根據電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容量和充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)特(te)性進行分階(jie)段充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，二者是(shi)不同的。電(dian)(dian)(dian)(dian)(dian)(dian)源適配(pei)器(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)源充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)的區(qu)別(bie)(bie)還體現在定義(yi)、結構(gou)、電(dian)(dian)(dian)(dian)(dian)(dian)流模式(shi)、用途等(deng)(deng)方面(mian)，最大的區(qu)別(bie)(bie)就是(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)器(qi)只(zhi)是(shi)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)(dian)(dian)源適配(pei)器(qi)不僅(jin)能(neng)給(gei)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)，還能(neng)給(gei)主機供電(dian)(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一(yi)般(ban)情況(kuang)下，電(dian)(dian)源適(shi)配器(qi)能(neng)否通(tong)(tong)用(yong)(yong)要(yao)滿足三個(ge)條件(jian)：輸出(chu)電(dian)(dian)壓必須相同、輸出(chu)的(de)(de)額定電(dian)(dian)流(liu)比(bi)原(yuan)電(dian)(dian)器(qi)要(yao)求的(de)(de)要(yao)大、接(jie)口相同，如(ru)果(guo)這三個(ge)方面都(dou)滿足的(de)(de)話，可以臨(lin)時(shi)通(tong)(tong)用(yong)(yong)一(yi)下。不過需(xu)要(yao)注意(yi)的(de)(de)是(shi)，部分電(dian)(dian)源適(shi)配器(qi)也是(shi)不可以通(tong)(tong)用(yong)(yong)的(de)(de)，通(tong)(tong)用(yong)(yong)可能(neng)會導致電(dian)(dian)器(qi)燒壞、無(wu)法使(shi)用(yong)(yong)等(deng)問題(ti)，因此如(ru)果(guo)原(yuan)來的(de)(de)電(dian)(dian)源適(shi)配器(qi)損壞，建議(yi)還是(shi)聯系廠家(jia)購買(mai)一(yi)個(ge)原(yuan)裝(zhuang)電(dian)(dian)源適(shi)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。
