style="text-indent:25px">在電源的應(yīng)用電路中，會出現(xiàn)大功率電源模塊輸出端電壓不正常，輸出端就是沒有任何輸出，大功率電源模塊也無損壞，是什么原因呢？或許是大功率電源模塊本身就無法啟動？外接電容過大（即容性負載過大），需要充電的時間變長，有些大功率電源模塊在規(guī)定時間內(nèi)不能建立好輸出電壓，就會進入過流保護，從而模塊無輸出；電子負載在CC模式下也會造成部分啟動能力弱的大功率電源模塊啟機不良，由于在CC模式下啟機的時候，其模擬的負載趨近于零，且反應(yīng)調(diào)節(jié)時間相對較長，絕大多數(shù)的大功率電源模塊應(yīng)用的環(huán)境屬于純電阻模式；負載需要的電流過大，而大功率電源模塊單位輸出的較大平均電流不夠?qū)е履K無法啟動；輸入線路過長，使得線路之間產(chǎn)生的壓降過大，而導(dǎo)致輸入電壓低于模塊輸入電壓的下限要求。</p><p style="text-indent:25px">***的大功率電源模塊都經(jīng)過專業(yè)的電源研發(fā)團隊按照嚴(yán)格的標(biāo)準(zhǔn)進行元器件選擇和認(rèn)證、專業(yè)的電氣設(shè)計和工藝開發(fā)、完善的可靠性測試和嚴(yán)格的生產(chǎn)測試，以確保其***高可靠性。其中測試包括全溫度范圍的電氣性能測試，環(huán)路穩(wěn)定性測試、可靠性測試，極限測試等。每一個大功率電源模塊在出廠前都會經(jīng)過系統(tǒng)嚴(yán)格的測試。相對而已，分立器件集成解決方案較難對電源進行深入的測試，因為整個供電系統(tǒng)與電路上的其他功能系統(tǒng)緊密聯(lián)系一起；模塊電源一般采用多層PCB或鋁基板，功率密度高，小型化。選擇小型化，高功率密度的模塊電源，可以給系統(tǒng)節(jié)省更多的空間。大功率電源模塊安全隔離：強電弱電隔離＼IGBT隔離驅(qū)動＼浪涌隔離保護＼雷電隔離保護。</p><div
