    兩者各自都要(yao)各自的(de)優點。所說的(de)銅(tong)芯充(chong)電(dian)(dian)器(qi)內部核(he)心原件是大(da)功率變(bian)(bian)(bian)壓(ya)(ya)器(qi)，多數是環(huan)形變(bian)(bian)(bian)壓(ya)(ya)器(qi)。電(dian)(dian)路(lu)板的(de)充(chong)電(dian)(dian)器(qi)，內部沒有(you)采用(yong)大(da)功率變(bian)(bian)(bian)壓(ya)(ya)器(qi)，而是由(you)開(kai)關電(dian)(dian)源取代。采用(yong)變(bian)(bian)(bian)壓(ya)(ya)器(qi)的(de)充(chong)電(dian)(dian)器(qi)往(wang)往(wang)體積比較大(da)，笨(ben)重(zhong)、便攜性差一(yi)些(xie)，因為(wei)變(bian)(bian)(bian)壓(ya)(ya)器(qi)應用(yong)銅(tong)線成本要(yao)高一(yi)些(xie)。而開(kai)關電(dian)(dian)源式充(chong)電(dian)(dian)器(qi)體積小重(zhong)量輕，便攜性強(qiang)，成本低要(yao)低一(yi)些(xie)。

    鐵(tie)芯變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)式(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)原理普遍比較簡單，不(bu)(bu)具備穩壓(ya)(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)，內部結構就(jiu)是(shi)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)＋整(zheng)流(liu)(liu)橋＋散熱風(feng)扇組成。電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)(lu)板上就(jiu)是(shi)多個整(zheng)流(liu)(liu)橋并聯，而風(feng)扇供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)則通(tong)過變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)抽頭(tou)(tou)取出低壓(ya)(ya)(ya)(ya)，整(zheng)流(liu)(liu)后(hou)經過LM7812穩壓(ya)(ya)(ya)(ya)后(hou)單獨為風(feng)扇供(gong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)。這類充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)其(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)調節就(jiu)是(shi)直接調整(zheng)變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)初級(ji)抽頭(tou)(tou)來實(shi)現的(de)，這種變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)初級(ji)留有多個抽頭(tou)(tou)，通(tong)過旋鈕選擇不(bu)(bu)同(tong)位置抽頭(tou)(tou)，也就(jiu)改(gai)變(bian)(bian)了(le)初/次級(ji)線(xian)圈比例，從而改(gai)變(bian)(bian)了(le)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，就(jiu)改(gai)變(bian)(bian)了(le)輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)。所以這類充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)市(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)波動就(jiu)會導致充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)(bu)穩定，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)(bu)精確。但是(shi)這類充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)功率大，輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度高，壽命也比較長、耐用(yong)。例如采用(yong)大容(rong)量水電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)動車，必(bi)須采用(yong)鐵(tie)芯變(bian)(bian)壓(ya)(ya)(ya)(ya)器(qi)式(shi)充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)器(qi)，輸(shu)出電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大、功率可以達到2000w左右，充(chong)(chong)(chong)(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)速度快。

    開關(guan)電(dian)(dian)(dian)源(yuan)式(shi)充電(dian)(dian)(dian)器(qi)，內部帶有(you)限流電(dian)(dian)(dian)路。輸出(chu)電(dian)(dian)(dian)壓(ya)精準，但是(shi)輸出(chu)電(dian)(dian)(dian)流比(bi)較(jiao)小(xiao)。大多數充電(dian)(dian)(dian)器(qi)帶有(you)恒壓(ya)限流功能。但是(shi)充電(dian)(dian)(dian)時(shi)間比(bi)較(jiao)長，適合(he)不經(jing)常(chang)充電(dian)(dian)(dian)的用(yong)(yong)戶使用(yong)(yong)。而且(qie)某些開關(guan)電(dian)(dian)(dian)源(yuan)壽命都(dou)很短(duan)，很容(rong)易(yi)損(sun)耗(hao)，而損(sun)壞后一文(wen)不值，沒有(you)修復的價值。優點(dian)就是(shi)體積(ji)小(xiao)巧、價格便宜。功率(lv)也不大，主要用(yong)(yong)在單塊(kuai)電(dian)(dian)(dian)池充電(dian)(dian)(dian)，或者為小(xiao)容(rong)量電(dian)(dian)(dian)池充電(dian)(dian)(dian)。如果做成2000w以上的功率(lv)，價格不會比(bi)鐵芯變壓(ya)器(qi)式(shi)充會器(qi)便宜。
