431)、光耦合電路、功率控制芯片和其他電路組成一個(gè)閉環(huán)控制回路時(shí)，任何問(wèn)題都會(huì)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(huì)導(dǎo)致輸出電壓偏低：電源模塊的負(fù)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(fù)載都應(yīng)該斷開，以區(qū)分功率模塊電路和負(fù)載電路。如果負(fù)載電路的電壓輸出正常，負(fù)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(fù)載能力的下降。acdc電源模塊普遍應(yīng)用于智能家居、較好燈飾、醫(yī)療、工控、辦公及民用等行業(yè)中。</p><div
