電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)(qi)又稱外(wai)(wai)置電(dian)(dian)源(yuan)，是一種小型便攜(xie)式(shi)電(dian)(dian)子設備及電(dian)(dian)子電(dian)(dian)器(qi)(qi)(qi)的供電(dian)(dian)電(dian)(dian)壓變(bian)(bian)換設備，由外(wai)(wai)殼、變(bian)(bian)壓器(qi)(qi)(qi)、電(dian)(dian)感、電(dian)(dian)容(rong)、控(kong)制IC、PCB板等元(yuan)器(qi)(qi)(qi)件組(zu)成，它的作用主(zhu)要是：將電(dian)(dian)流由交(jiao)流輸(shu)入轉(zhuan)換為(wei)直流輸(shu)出，把不穩定的電(dian)(dian)源(yuan)通過(guo)轉(zhuan)化(hua)電(dian)(dian)路變(bian)(bian)成電(dian)(dian)子產品需要的恒(heng)壓直流電(dian)(dian)，從而(er)給物(wu)體供電(dian)(dian)和(he)充電(dian)(dian)。電(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)(qi)可以(yi)看(kan)作是變(bian)(bian)壓器(qi)(qi)(qi)和(he)整流器(qi)(qi)(qi)，可以(yi)起(qi)到保(bao)護(hu)電(dian)(dian)器(qi)(qi)(qi)和(he)人身安全的作用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)(qi)(qi)(qi)并(bing)不是(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)(qi)(qi)(qi)是(shi)(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)開關，用(yong)于提供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力能(neng)(neng)源(yuan)，可以給(gei)(gei)投影儀、筆記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)(qi)(qi)(qi)(qi)等家用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品提供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力；而充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)是(shi)(shi)用(yong)來給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)，一般會根據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池容(rong)量和充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)特性(xing)進行分(fen)階段充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，二者(zhe)是(shi)(shi)不同的(de)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)(qi)(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)的(de)區(qu)別還體現在定義、結構、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)模式、用(yong)途(tu)等方面，最大的(de)區(qu)別就是(shi)(shi)充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)(qi)(qi)(qi)只是(shi)(shi)給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)配器(qi)(qi)(qi)(qi)(qi)不僅能(neng)(neng)給(gei)(gei)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池充(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，還能(neng)(neng)給(gei)(gei)主機(ji)供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一般情況下，電源適(shi)配器(qi)能(neng)(neng)否通(tong)用要(yao)(yao)滿(man)足三個(ge)條件(jian)：輸出電壓必須(xu)相同、輸出的額定電流比原(yuan)電器(qi)要(yao)(yao)求的要(yao)(yao)大、接口(kou)相同，如果(guo)(guo)這三個(ge)方(fang)面都滿(man)足的話，可(ke)以臨(lin)時通(tong)用一下。不(bu)過需(xu)要(yao)(yao)注(zhu)意的是(shi)(shi)(shi)，部(bu)分電源適(shi)配器(qi)也是(shi)(shi)(shi)不(bu)可(ke)以通(tong)用的，通(tong)用可(ke)能(neng)(neng)會導致電器(qi)燒壞、無法使(shi)用等問題，因(yin)此如果(guo)(guo)原(yuan)來的電源適(shi)配器(qi)損壞，建議還(huan)是(shi)(shi)(shi)聯系廠家購買一個(ge)原(yuan)裝電源適(shi)配器(qi)比較好(hao)。

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。
