我們都知道(dao)電源(yuan)可以分(fen)為(wei)線性(xing)電源(yuan)和開(kai)關(guan)電源(yuan)兩大類。開(kai)關(guan)電源(yuan)與線性(xing)電源(yuan)不(bu)同，它的(de)電路型式(shi)(shi)主要有單(dan)端(duan)反激式(shi)(shi)，單(dan)端(duan)正(zheng)激式(shi)(shi)、半(ban)橋(qiao)式(shi)(shi)、推挽(wan)式(shi)(shi)和全橋(qiao)式(shi)(shi)。它和線性(xing)電源(yuan)的(de)根本區(qu)別在(zai)(zai)于它變壓(ya)器不(bu)工(gong)(gong)作在(zai)(zai)工(gong)(gong)頻而(er)是工(gong)(gong)作在(zai)(zai)幾(ji)(ji)十千赫茲到幾(ji)(ji)兆赫茲。功(gong)能管不(bu)是工(gong)(gong)作在(zai)(zai)飽和及截止區(qu)即(ji)開(kai)關(guan)狀態；開(kai)關(guan)電源(yuan)因此而(er)得名(ming)。而(er)如(ru)果細分(fen)的(de)話開(kai)關(guan)電源(yuan)又可以分(fen)為(wei)很多類，接(jie)下來就讓電源適(shi)配器廠家和大(da)家講(jiang)講(jiang)。

　　　①、AC/DC電(dian)源(yuan)

　　該(gai)類電(dian)源(yuan)(yuan)也稱一(yi)(yi)(yi)次電(dian)源(yuan)(yuan)，它自電(dian)網取得(de)能量，經過高壓整(zheng)流濾波得(de)到一(yi)(yi)(yi)個(ge)直(zhi)流高壓，供DC/DC變換器在輸(shu)(shu)出(chu)端獲得(de)一(yi)(yi)(yi)個(ge)或幾個(ge)穩定的(de)直(zhi)流電(dian)壓，功率從幾瓦－幾千瓦均有(you)產(chan)品，用于不(bu)同場合。屬(shu)此(ci)類產(chan)品的(de)規(gui)格型(xing)號繁多，據用戶(hu)需要而定通信電(dian)源(yuan)(yuan)中的(de)一(yi)(yi)(yi)次電(dian)源(yuan)(yuan)（AC220輸(shu)(shu)入(ru)，DC48V或24V輸(shu)(shu)出(chu))也屬(shu)此(ci)類.

　　②、DC/DC電源

　　在通(tong)信系統中也稱(cheng)二次(ci)電源，它是由一次(ci)電源或直(zhi)(zhi)流(liu)(liu)電池組提(ti)供一個直(zhi)(zhi)流(liu)(liu)輸入電壓，經DC/DC變換以后在輸出端獲一個或幾個直(zhi)(zhi)流(liu)(liu)電壓。

　　③、通信電源

　　通信電(dian)(dian)(dian)(dian)源(yuan)其實(shi)質上就是(shi)DC/DC變(bian)換器(qi)式電(dian)(dian)(dian)(dian)源(yuan)，只是(shi)它一般以(yi)直流－48V或－24V供(gong)(gong)電(dian)(dian)(dian)(dian)，并用后備電(dian)(dian)(dian)(dian)池作(zuo)DC供(gong)(gong)電(dian)(dian)(dian)(dian)的(de)備份，將DC的(de)供(gong)(gong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓變(bian)換成電(dian)(dian)(dian)(dian)路的(de)工作(zuo)電(dian)(dian)(dian)(dian)壓，一般它又分(fen)中(zhong)央(yang)供(gong)(gong)電(dian)(dian)(dian)(dian)、分(fen)層供(gong)(gong)電(dian)(dian)(dian)(dian)和(he)單(dan)板供(gong)(gong)電(dian)(dian)(dian)(dian)三種，以(yi)后者可靠性最高。

　　④、電臺電源

　　電(dian)(dian)(dian)(dian)臺電(dian)(dian)(dian)(dian)源(yuan)輸入AC220V/110V，輸出DC13.8V,功(gong)率由所(suo)供(gong)電(dian)(dian)(dian)(dian)臺功(gong)率而(er)定,幾安幾百安均(jun)有產品.為防止AC電(dian)(dian)(dian)(dian)網斷電(dian)(dian)(dian)(dian)影(ying)響(xiang)電(dian)(dian)(dian)(dian)臺工作(zuo),而(er)需(xu)要有電(dian)(dian)(dian)(dian)池(chi)組作(zuo)為備(bei)份,所(suo)以(yi)此類電(dian)(dian)(dian)(dian)源(yuan)除輸出一個13.8V直流電(dian)(dian)(dian)(dian)壓外,還具有對(dui)電(dian)(dian)(dian)(dian)池(chi)充電(dian)(dian)(dian)(dian)自(zi)動(dong)轉換功(gong)能。

　　⑤、模塊(kuai)電源(yuan)

　　隨著科(ke)學技術飛速(su)發展，對(dui)電(dian)源可(ke)靠性(xing)(xing)、容量/體積比要求(qiu)越(yue)來越(yue)高(gao)，模(mo)塊電(dian)源越(yue)來越(yue)顯示其優(you)越(yue)性(xing)(xing)，它工作頻率(lv)高(gao)、體積小、可(ke)靠性(xing)(xing)高(gao)，便于(yu)安(an)裝(zhuang)和組合擴(kuo)容，所以(yi)越(yue)來越(yue)被廣泛采用。目前(qian)，目前(qian)國內雖有相應模(mo)塊生產，但因生產工藝未能趕上國際水平(ping)，故障率(lv)較高(gao)。

　　　　⑥、特種電源

　　高電(dian)壓小電(dian)流(liu)電(dian)源、大電(dian)流(liu)電(dian)源、400Hz輸入的(de)AC/DC電(dian)源等(deng)，可(ke)(ke)歸于此類，可(ke)(ke)根據特殊需要選用(yong)。開關電(dian)源的(de)價(jia)(jia)位一(yi)般(ban)在2-8元(yuan)(yuan)/瓦特殊小功(gong)率和大功(gong)率電(dian)源價(jia)(jia)格稍高，可(ke)(ke)達(da)11-13元(yuan)(yuan)/瓦。

作為電源(yuan)(yuan)(yuan)適配器(qi)廠家，飛天鷹(ying)主要(yao)生產(chan)的(de)是100W以內的(de)小家電電源(yuan)(yuan)(yuan)、USB充電器(qi)、IT/AV類(lei)電源(yuan)(yuan)(yuan)、平衡車電源(yuan)(yuan)(yuan)、另外還有共享充電寶(bao)和礦機電源(yuan)(yuan)(yuan)等(deng)，想要(yao)了解更多電源(yuan)(yuan)(yuan)信(xin)息？歡迎(ying)聯系我們。
