id="bvnprtf" class="box"><p><p style="text-indent:25px">大功率電源模塊啟動困難，首先是破壞力較小的情況——大功率電源模塊在啟動中出現(xiàn)啟動困難，甚至啟動不了。大家在使用大功率電源模塊過程中可能會出現(xiàn)電源模塊輸出端電壓正常，輸出端就是沒有任何輸出，電源模塊也無損壞，是什么原因呢？具體原因如下所示：外接電容過大；容性負載過大；負載電流過大；輸入電源功率不夠，山東大功率電源模塊生產(chǎn)線。針對這一類問題，可以通過調(diào)整輸出端的電容以及負載或調(diào)整輸入端的功率進行改善，具體如下所示：外接電容過大，山東大功率電源模塊生產(chǎn)線，在電源模塊啟動時向其充電較長時間，難以啟動，需要選擇合適的容性負載；容性負載過大時需可先串聯(lián)一個合適的電感；輸出負載過重是會造成啟動時間延長，山東大功率電源模塊生產(chǎn)線，選擇合適負載；換用功率更大的輸入電源。大功率電源模塊采用模塊式的設(shè)計有助節(jié)省成本及開發(fā)時間。山東大功率電源模塊生產(chǎn)線</p><div

style="text-indent:25px">大功率電源模塊有多種輸入輸出選擇，并且可以重復(fù)加或交叉加，構(gòu)成積木式組合電源，從而實現(xiàn)多路輸入輸出。相比分立式，調(diào)試更加簡單安全，使設(shè)計應(yīng)用有效簡化，縮短開發(fā)時間。模塊一般采用自動化工藝，保證品質(zhì)和可靠性。大功率電源模塊是經(jīng)過了專業(yè)電源研發(fā)團隊按照嚴格標準來選擇元件，經(jīng)過設(shè)計和開發(fā)，進行過完善的可靠性測試和批量生產(chǎn)測試。而分立式方案就較難進行深入的測試。大功率電源模塊功率密度較高，體積較小，節(jié)省了系統(tǒng)的占用空間。分立式方案難以達到這樣的標準。山東大功率電源模塊生產(chǎn)線開關(guān)電源在輸入抗干擾性能上，由于其自身電路結(jié)構(gòu)的特點（多級串聯(lián)）。</p><div

style="text-indent:25px">高頻逆變式整流焊機電源是一種高性能、高效、省材的新型焊機電源,反映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,解決了大功率IGBT逆變電源可靠性。</p><p style="text-indent:25px">輸入保護電路：一般模塊電源產(chǎn)品都有內(nèi)置濾波器，能滿足一般電源應(yīng)用的要求。如果需要更高要求的電源系統(tǒng)，應(yīng)增加輸入濾波網(wǎng)絡(luò)?？梢圆捎肔C或π型網(wǎng)絡(luò)，但應(yīng)注意盡量選擇較小的電感和較大的電容。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)。為了降低共模噪聲，可以增加Y(Cy)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)。用途普遍：模塊電源可普遍應(yīng)用于航空航天、機車艦船、**兵器、發(fā)電配電、郵電通信、冶金礦山、自動控制、家用電器、儀器儀表和科研實驗等社會生產(chǎn)和生活的各個領(lǐng)域，尤其是在高可靠和高技術(shù)領(lǐng)域發(fā)揮著不可替代的重要作用。開關(guān)電源是較大的EMC干擾源。</p><div
