1.充電器(qi)是一(yi)種將交流(liu)電轉換(huan)為低壓直流(liu)電的(de)供電設(she)備，采用電力電子半導體(ti)器(qi)件，將電壓和(he)頻率固(gu)定不(bu)變的(de)交流(liu)電變換(huan)為直流(liu)電的(de)一(yi)種靜止變流(liu)裝置(zhi)。

2.適(shi)(shi)配(pei)器(qi)就是(shi)一個(ge)接(jie)口轉移器(qi)，一般(ban)由外殼、電(dian)(dian)(dian)(dian)(dian)源(yuan)變壓器(qi)和整流電(dian)(dian)(dian)(dian)(dian)路組成，適(shi)(shi)用于(yu)小型便攜(xie)式電(dian)(dian)(dian)(dian)(dian)子設(she)備(bei)及電(dian)(dian)(dian)(dian)(dian)子電(dian)(dian)(dian)(dian)(dian)器(qi)的(de)供電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)源(yuan)變換(huan)設(she)備(bei)。適(shi)(shi)配(pei)器(qi)可以是(shi)一個(ge)獨立的(de)硬件接(jie)口設(she)備(bei)，也(ye)可以是(shi)信息接(jie)口。通常(chang)使用的(de)適(shi)(shi)配(pei)器(qi)一般(ban)有(you)電(dian)(dian)(dian)(dian)(dian)源(yuan)適(shi)(shi)配(pei)器(qi)、USB與串口的(de)轉接(jie)設(she)備(bei)等(deng)。

總結：充電(dian)器(qi)是包括了適(shi)配器(qi)功(gong)能的，它(ta)比適(shi)配器(qi)多(duo)一個控制(zhi)電(dian)路(lu)。適(shi)配器(qi)只起到穩壓作用，充電(dian)器(qi)具有恒流和限壓設計。
