YAG激光焊接機是市場占有量比較大的一種機型，它的電源是整機的重要組成部分。通發激光在國產YAG激光焊接機制造業中具有絕對優勢，它的電源成熟穩定。主要是自主研發的以下兩種電源：

    1、普通型：三相380V交流電(dian)

    通(tong)過整流(liu)電(dian)(dian)(dian)路附帶(dai)緩沖電(dian)(dian)(dian)路，對(dui)儲(chu)能電(dian)(dian)(dian)解電(dian)(dian)(dian)容(rong)進行充電(dian)(dian)(dian)到約550Vdc。放電(dian)(dian)(dian)電(dian)(dian)(dian)路由(you)通(tong)過空心電(dian)(dian)(dian)感，IGBT高拋開關進行設定電(dian)(dian)(dian)流(liu)值產(chan)生脈沖電(dian)(dian)(dian)流(liu)對(dui)氙燈(deng)放電(dian)(dian)(dian)。預燃(ran)氙燈(deng)電(dian)(dian)(dian)路通(tong)過一個工頻高壓(ya)變壓(ya)器，整流(liu)產(chan)生1200V，進行分壓(ya)處理，啟動高壓(ya)包，產(chan)生一萬多伏的高壓(ya)觸發氙燈(deng)，通(tong)過維持(chi)電(dian)(dian)(dian)阻預燃(ran)氙燈(deng)。

    2、改(gai)進型：三相(xiang)380V交流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)到整(zheng)流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)，通(tong)過BOOST電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)，芯(xin)片驅(qu)動控(kong)(kong)制反(fan)饋和升壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)，升壓(ya)(ya)(ya)到約700VDC對儲能電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)進行充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)由通(tong)過空心電(dian)(dian)(dian)(dian)(dian)(dian)(dian)感(gan)(gan)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流傳感(gan)(gan)器取(qu)樣，單片機控(kong)(kong)制IGBT高(gao)拋開(kai)關(guan)，根據(ju)設(she)定電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流值，反(fan)饋控(kong)(kong)制，產生(sheng)脈(mo)沖電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流對氙燈(deng)(deng)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)。預(yu)燃(ran)氙燈(deng)(deng)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)通(tong)過一個(ge)高(gao)頻開(kai)關(guan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源，整(zheng)流輸出部分(fen)通(tong)過7次倍壓(ya)(ya)(ya)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)路(lu)，產生(sheng)高(gao)壓(ya)(ya)(ya)1萬伏(fu)脈(mo)沖對氙燈(deng)(deng)激發，700V通(tong)過限流電(dian)(dian)(dian)(dian)(dian)(dian)(dian)阻對氙燈(deng)(deng)進行維持小電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，進行預(yu)燃(ran)狀態(tai)。(下(xia)圖為通(tong)發激光(guang)改(gai)進型電(dian)(dian)(dian)(dian)(dian)(dian)(dian)源)

    它們(men)的優(you)點是：

   ; 普通型的電源成(cheng)本較改進型便宜，技術(shu)成(cheng)熟穩(wen)定。

    改進型之所以(yi)為了(le)把電(dian)(dian)(dian)(dian)(dian)壓(ya)升壓(ya)到700VDC左右，一是(shi)為了(le)充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)的(de)(de)(de)穩(wen)定性；二是(shi)為了(le)適(shi)應各種不同弧長的(de)(de)(de)氙燈，保證有最大電(dian)(dian)(dian)(dian)(dian)流的(de)(de)(de)輸出。電(dian)(dian)(dian)(dian)(dian)源成本(ben)相對貴(gui)，對控制(zhi)電(dian)(dian)(dian)(dian)(dian)路和(he)整個電(dian)(dian)(dian)(dian)(dian)源裝配(pei)生產工藝要(yao)求高。

    通發激光有近30人的研發團隊和100多的生產員工，長期至力生產和改進國產YAG激光焊接機，使之更好地為祖國的工業發展出力。
