電源適配器行業簡介

一、電源適配器是什么

電(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)又稱外置電(dian)(dian)(dian)源(yuan)，是(shi)(shi)一種小(xiao)型便攜式電(dian)(dian)(dian)子設備及電(dian)(dian)(dian)子電(dian)(dian)(dian)器(qi)(qi)的(de)供電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)(ya)變(bian)換(huan)設備，由(you)外殼(ke)、變(bian)壓(ya)(ya)器(qi)(qi)、電(dian)(dian)(dian)感、電(dian)(dian)(dian)容(rong)、控制(zhi)IC、PCB板(ban)等元器(qi)(qi)件組成，它的(de)作(zuo)用主要是(shi)(shi)：將電(dian)(dian)(dian)流由(you)交流輸入轉換(huan)為直流輸出，把不(bu)穩定的(de)電(dian)(dian)(dian)源(yuan)通過轉化電(dian)(dian)(dian)路(lu)變(bian)成電(dian)(dian)(dian)子產品(pin)需要的(de)恒壓(ya)(ya)直流電(dian)(dian)(dian)，從而給物(wu)體供電(dian)(dian)(dian)和充電(dian)(dian)(dian)。電(dian)(dian)(dian)源(yuan)適(shi)配(pei)器(qi)(qi)可以看(kan)作(zuo)是(shi)(shi)變(bian)壓(ya)(ya)器(qi)(qi)和整流器(qi)(qi)，可以起到(dao)保護電(dian)(dian)(dian)器(qi)(qi)和人身安全(quan)的(de)作(zuo)用。

二、電源適配器是充電器嗎

電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)并不是(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)是(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)開(kai)關(guan)，用(yong)于提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)能源(yuan)，可以(yi)給投(tou)影儀、筆記本電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦、音響、凈水器(qi)(qi)等家(jia)用(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)或電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品提供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)力(li)；而(er)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)是(shi)用(yong)來給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)，一般會根(gen)據電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)容量(liang)和充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)特性進(jin)行分階段充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，二(er)者是(shi)不同的(de)(de)。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)和電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)的(de)(de)區別還(huan)體(ti)現在定義、結(jie)構、電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流模(mo)式、用(yong)途等方面，最大的(de)(de)區別就是(shi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)(qi)只是(shi)給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，而(er)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)(qi)不僅能給電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)，還(huan)能給主機(ji)供電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。

三、電源適配器可以通用嗎

一(yi)般情況下(xia)(xia)，電(dian)(dian)源適配(pei)器(qi)能否通用(yong)要滿足三個(ge)條件：輸(shu)出電(dian)(dian)壓必須相同、輸(shu)出的(de)(de)(de)額定(ding)電(dian)(dian)流比原(yuan)電(dian)(dian)器(qi)要求的(de)(de)(de)要大、接(jie)口相同，如(ru)果(guo)這三個(ge)方面都滿足的(de)(de)(de)話，可(ke)以臨時(shi)通用(yong)一(yi)下(xia)(xia)。不過(guo)需要注意的(de)(de)(de)是(shi)，部分電(dian)(dian)源適配(pei)器(qi)也是(shi)不可(ke)以通用(yong)的(de)(de)(de)，通用(yong)可(ke)能會導致(zhi)電(dian)(dian)器(qi)燒(shao)壞、無法使用(yong)等問題，因(yin)此(ci)如(ru)果(guo)原(yuan)來(lai)的(de)(de)(de)電(dian)(dian)源適配(pei)器(qi)損壞，建(jian)議還是(shi)聯系廠家購買一(yi)個(ge)原(yuan)裝電(dian)(dian)源適配(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。
