style="text-indent:25px">電源模塊沒有工作或進入保護狀態(tài)。首先，有必要測量功率控制芯片的啟動腳是否有啟動電壓。如果沒有啟動電壓或啟動電壓太低，必須檢查起動電阻和啟動腳的外部部件是否泄漏。此時，如果電源控制芯片正常，則可以通過上述檢查快速檢測故障。如果有啟動電壓，那么控制芯片的輸出在啟動時刻是否有高、低電平跳變，如果沒有跳變，說明控制芯片不好，**電路振蕩元件或保護電路出現(xiàn)問題，可以更換控制芯片，然后檢查**元件；如果有跳變，開關(guān)管一般是壞的或損壞的。主要檢查300 V、整流橋二極管和開關(guān)管等部分的大濾波電容，抗干擾電路問題也會導(dǎo)致安全燃燒、發(fā)黑。應(yīng)注意的是，由于開關(guān)管的故障，電流檢測電阻和功率控制芯片將被燒毀。負溫度系數(shù)熱敏電阻也容易被保險燒毀。</p><p

431)、光耦合電路、功率控制芯片和其他電路組成一個閉環(huán)控制回路時，任何問題都會導(dǎo)致輸出電壓的增加。除穩(wěn)定的電壓控制電路外，輸出電壓太低，這將導(dǎo)致輸出電壓偏低，以下一些原因也會導(dǎo)致輸出電壓偏低：電源模塊的負載有短路故障(特別是短路或DC/DC變換器性能差等)。電源模塊電路的所有負載都應(yīng)該斷開，以區(qū)分功率模塊電路和負載電路。如果負載電路的電壓輸出正常，負載太重，或者表示功率模塊電路有故障仍然是異常的。輸出電壓端子整流二極管，濾波電容失效等，可以用替代法判斷。開關(guān)管的性能下降，必然導(dǎo)致開關(guān)管的正常導(dǎo)通、電源內(nèi)阻的增大和負載能力的下降。模塊電源容值相當(dāng)于串聯(lián)模塊的功率感覺。靜安區(qū)ACDC電源模塊公司有哪些</p><p

style="text-indent:25px">AC/DC電源就是輸入為交流，輸出為直流的電源變換器。例如我們常用的手機充電器、筆記本、平板電腦的電源適配器都是這種電源。在這個電源變換器內(nèi)部包含有降壓電路、整流濾波電路、和穩(wěn)壓電路。在dcdc電源模塊應(yīng)用中，要求有較寬的輸入范圍，通常要求：85V~265V的交流輸入，輸出電源轉(zhuǎn)換效率要求高，同時能有效提高節(jié)能效能，滿負載效率在AC/DC電源設(shè)計中是一項主要考慮因素。提高AC/DC轉(zhuǎn)換器效率，實現(xiàn)更好的節(jié)能性能的方法，是綠色能源的倡導(dǎo)。開關(guān)電源是利用現(xiàn)代電力電子技術(shù)，控制開關(guān)管開通和關(guān)斷的時間比率，維持穩(wěn)定輸出電壓的一種電源，而AC/DC就是開關(guān)電源的其中的一類。AC/DC開關(guān)電源AC是交流，DC是直流，它經(jīng)過高壓整流濾波得出一個直流高壓，供DC/DC變換器在輸出端獲得一個或幾個穩(wěn)定的直流電壓，功率從幾瓦－幾千瓦均有產(chǎn)品，用于不同場合。屬此類產(chǎn)品的規(guī)格型號繁多，據(jù)用戶需要而定通信電源中的一次電源（AC220輸入，DC48V或24V輸出)也屬此類。在這個電源變換器內(nèi)部包含有降壓電路、整流濾波電路、和穩(wěn)壓電路。靜安區(qū)ACDC電源模塊公司有哪些</p><p
