style="text-indent:25px">dc-dc電源模塊通常都會發(fā)生的問題或故障，電壓輸入過高的問題導(dǎo)致故障發(fā)生，就是輸入的電壓過高，是因為輸出端的懸空或者是沒有負載，也有可能是因為輸出端負載太輕，如果輕與百分之十的額定負載也會導(dǎo)致，再來就是輸入的電壓偏高或者是電壓受到干擾，這些問題都是導(dǎo)致電壓輸入過高的源頭。如同電壓輸入過高，如果電壓輸出過低也可能導(dǎo)致問題的出現(xiàn)。這能導(dǎo)致整體系統(tǒng)不能正常的工作，就例如微控制器系統(tǒng)中，負載會突然增大，從而會拉低微控制器所供電電壓，就容易造成復(fù)位。是因為輸入的電壓不足，或者是功率不足。其次是輸出線路過長或者過細又或者是輸入端的防反接二極管壓降太大導(dǎo)致。如果輸出的紋波聲過大的話，也就證明這是一塊劣質(zhì)的電源模塊。噪音是衡量電源模塊好壞的一大關(guān)鍵指標。如果發(fā)出噪聲的話這個電源模塊還是不要用為好。通常造成噪聲過大原因就是電源模塊與主電路噪聲敏感元件距離比較近，還有主電路的噪聲敏感元件的電源輸入端出沒有接去耦電容。還有電線處理不合格等等這些原因都會導(dǎo)致問題的出現(xiàn)。</p><p 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。電源模塊也是這個變流技術(shù)設(shè)備的本質(zhì)。</p><div
