style="text-indent:25px">焊機電源模塊：高頻逆變式整流焊機電源是一種高性能、***、省材的新型焊機電源,**了當今焊機電源的發(fā)展方向。由于IGBT大容量模塊的商用化,這種電源更有著廣闊的應(yīng)用前景。逆變焊機電源大都采用交流-直流-交流-直流(AC-DC-AC-DC)變換的方法。50Hz交流電經(jīng)全橋整流變成直流,IGBT組成的PWM高頻變換部分將直流電逆變成20kHz的高頻矩形波,經(jīng)高頻變壓器耦合, 整流濾波后成為穩(wěn)定的直流,供電弧使用。由于焊機電源的工作條件惡劣,頻繁的處于短路、燃弧、開路交替變化之中,因此高頻逆變式整流焊機電源的工作可靠性問題成為**關(guān)鍵的問題,也是用戶**關(guān)心的問題。采用微處理器做為脈沖寬度調(diào)制(PWM)的相關(guān)控制器,通過對多參數(shù)、多信息的提取與分析,達到預(yù)知系統(tǒng)各種工作狀態(tài)的目的,進而提前對系統(tǒng)做出調(diào)整和處理,解決了當前大功率IGBT逆變電源可靠性。國外逆變焊機已可做到額定焊接電流300A,負載持續(xù)率60%,全載電壓60~75V,電流調(diào)節(jié)范圍5~300A,重量29kg。</p><div

style="text-align:left;"> 為了防止輸入電源瞬態(tài)高壓損壞模塊電源，建議用戶在輸入端接瞬態(tài)吸收二極管并配合保險絲使用，以確保模塊在安全的輸入電壓范圍之內(nèi)。 <p> 為了降低共模噪聲，可以增加Y電容，一般選擇幾nf高頻電容。R為保險絲，D1為保護二極管，D2為瞬態(tài)吸收二極管(P6KE系列)。 </p> <p> 充電模塊遙控開關(guān)電路： </p> <p> 模塊電源的遙控開關(guān)操作，是通過REM端進行的。一般控制方式有兩種： </p> <p> REM與-VIN(參考地)相連，遙控關(guān)斷，要求VREF<0.4V。REM懸空或與+VIN相連，模塊工作，要求VREM>1V。 </p> <p> REM與VIN相連，遙控關(guān)斷，要求VREM<0.4V。REM與+VIN相連，模塊工作，要求VREM>1V。REM懸空，遙控關(guān)斷，即所謂“懸空關(guān)斷”(-R)。 </p> <p> 如果充電模塊控制要與輸入端隔離，則可以使用光電耦合器作為傳遞控制信號。 </p> <br /> </div></p><br /><p>文章來源地址:
