style="text-indent:25px">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較關(guān)鍵的問題,也是用戶較關(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(dá)到預(yù)知系統(tǒng)各種工作狀態(tài)的目的,進(jìn)而提前對系統(tǒng)做出調(diào)整和處理,解決了當(dāng)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(fù)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。大功率開關(guān)型高壓直流電源普遍應(yīng)用于靜電除塵、水質(zhì)改良、醫(yī)用X光機和CT機等大型設(shè)備。電壓高達(dá)50~l59kV,電流達(dá)到0.5A以上,功率可達(dá)100kW。遼寧DCDC電源模塊用途高頻小型化的開關(guān)電源及其技術(shù)已成為現(xiàn)代通信供電系統(tǒng)的主流。</p><div

style="text-indent:25px">設(shè)法降低模塊電源的溫升，模塊內(nèi)部器件的工作溫度的高低直接影響模塊電源的壽命，器件溫度越低模塊壽命越長。在一定的工作條件下，模塊電源的損耗是一定的，但是可以通過改善模塊電源的散熱條件來降低其溫升，從而有效的延長其使用壽命。比如：50W以上的模塊電源必須安裝散熱器，散熱器的表面積越大越有利于散熱，且散熱器的安裝方向應(yīng)盡量有利于空氣的自然對流，功率在150W以上除安裝散熱器以外還可以加裝扇強制風(fēng)冷。此外在環(huán)境溫度較高或空氣流通條件較差的地方模塊須降額使用以減小功耗從而降低溫升，延長使用壽命。</p><p style="text-indent:25px">合理安裝減小機械應(yīng)力，模塊電源的引出方式均為金屬針，模塊電源與外接線路、金屬針與模塊電源內(nèi)路電路均采用焊接方式連接。在一些特殊場合機械振動強度較大，尢其是大功率模塊電源上還要加裝散熱器，這種情況更為嚴(yán)重。雖然模塊電源內(nèi)部一般灌封導(dǎo)熱絕緣橡膠可以對元件起到較好的緩沖保護(hù)作用，但焊點有可能經(jīng)受不住強烈振動應(yīng)力而斷裂，導(dǎo)致模塊電源工作失效，這時必須在焊接的基礎(chǔ)上再采取另外的固定和緩沖措施，比如可以用夾具或螺栓（對于有螺孔模塊）將模塊與機箱、大線路板等相對抗振性能好的部件固定，并且在它們中間墊一些彈性材料以緩沖振動產(chǎn)生的應(yīng)力。總之，模塊電源和其它元器件一樣只有精心選擇、合理應(yīng)用才能使其性能得到較大發(fā)揮，可靠性得到充分保障，模塊電源也才會被更普遍地采用。變頻器電源主要用于交流電機的變頻調(diào)速。</p><div
