我們知道電(dian)(dian)有(you)直流(liu)與交流(liu)之(zhi)分，同樣電(dian)(dian)源也有(you)直流(liu)電(dian)(dian)源與交流(liu)電(dian)(dian)源之(zhi)分，那么(me)難這(zhe)二者有(you)何區別(bie)呢？，接下來就讓電源適配器(qi)廠家為大(da)家(jia)解釋一下吧。

直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，是維持(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)中(zhong)形成穩恒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流(liu)的(de)(de)裝置。如(ru)干電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池、蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池、直流(liu)發電(dian)(dian)(dian)(dian)(dian)(dian)(dian)機等。直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源的(de)(de)類型很多，不同類型的(de)(de)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源中(zhong)，非靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力的(de)(de)性質不同，能量轉(zhuan)換的(de)(de)過程也不同。在(zai)化(hua)(hua)學電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池（例如(ru)干電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池、蓄電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池等）中(zhong)，非靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力是與離子的(de)(de)溶解和(he)沉(chen)積過程相聯(lian)系的(de)(de)化(hua)(hua)學作(zuo)用,化(hua)(hua)學電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)時,化(hua)(hua)學能轉(zhuan)化(hua)(hua)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能和(he)焦耳熱(re)在(zai)溫差(cha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源（例如(ru)金屬溫差(cha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)偶、半導體溫差(cha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)偶）中(zhong)，非靜(jing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)力是與溫度(du)差(cha)和(he)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子的(de)(de)濃(nong)度(du)差(cha)相聯(lian)系的(de)(de)擴散作(zuo)用，溫差(cha)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源向外電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)提供功率時，熱(re)能部分地轉(zhuan)化(hua)(hua)為電(dian)(dian)(dian)(dian)(dian)(dian)(dian)能

交(jiao)流(liu)電(dian)(dian)(dian)源(yuan)是現代詞，是一個專(zhuan)有名詞，指的(de)是插頭(tou)與(yu)插座指用(yong)(yong)來(lai)(lai)接上用(yong)(yong)來(lai)(lai)將市電(dian)(dian)(dian)提供(gong)的(de)交(jiao)流(liu)電(dian)(dian)(dian)，使(shi)家用(yong)(yong)電(dian)(dian)(dian)器(qi)與(yu)可攜式小型(xing)設備(bei)(bei)通(tong)電(dian)(dian)(dian)可使(shi)用(yong)(yong)的(de)裝(zhuang)置。　家用(yong)(yong)交(jiao)流(liu)電(dian)(dian)(dian)源(yuan)插頭(tou)與(yu)插座指用(yong)(yong)來(lai)(lai)接上用(yong)(yong)來(lai)(lai)將市電(dian)(dian)(dian)提供(gong)的(de)交(jiao)流(liu)電(dian)(dian)(dian)，使(shi)家用(yong)(yong)電(dian)(dian)(dian)器(qi)與(yu)可攜式小型(xing)設備(bei)(bei)通(tong)電(dian)(dian)(dian)可使(shi)用(yong)(yong)的(de)裝(zhuang)置。

二者(zhe)的區(qu)別：

交流電是(shi)按正(zheng)弦(xian)曲線變(bian)化的(de)，由于交流發(fa)電機,在發(fa)電過程中(zhong)，多對(dui)磁極(ji)是(shi)按一(yi)定的(de)角度均勻(yun)分布在一(yi)個(ge)圓周上，使得發(fa)電過程中(zhong)，各個(ge)磁極(ji)切割磁力線的(de)時候，具有(you)互補性，所以能夠不斷的(de)產生(sheng)穩定的(de)電流；交流電的(de)頻率一(yi)般是(shi)50赫茲，即每秒(miao)變(bian)化50次(ci)，當然也有(you)其(qi)它頻率。

直(zhi)流電則不是按(an)正弦曲(qu)線變(bian)化的(de).沒有(you)頻率(lv)的(de)變(bian)化.。

　　交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)與直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)最直觀的(de)(de)區(qu)別是方(fang)向(xiang)變(bian)不變(bian)；直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)的(de)(de)電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)方(fang)向(xiang)是不隨時問變(bian)化的(de)(de)，但大小可能變(bian)化；最特(te)殊的(de)(de)直流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)是大小方(fang)向(xiang)都不變(bian)的(de)(de)穩恒電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)。所謂交流(liu)(liu)(liu)(liu)，就是電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)交替(ti)流(liu)(liu)(liu)(liu)動，其方(fang)向(xiang)是交替(ti)變(bian)化的(de)(de)，最常見的(de)(de)是民用(yong)電(dian)(dian)(dian)，它是正（余）弦式交流(liu)(liu)(liu)(liu)電(dian)(dian)(dian)，電(dian)(dian)(dian)微電(dian)(dian)(dian)子電(dian)(dian)(dian)路中(zhong)常見的(de)(de)有方(fang)波電(dian)(dian)(dian)流(liu)(liu)(liu)(liu)。
