style="text-indent:25px">開關(guān)電源中的pfc是什么意思？PFC就是功率因數(shù)校正，由于開關(guān)電源不是純電阻負載，屬于容性負載，大量的開關(guān)電源同時使用會干擾電網(wǎng)，使電網(wǎng)不平衡。一般開關(guān)電源的功率因數(shù)PF為0.6左右。理想的純電阻負載功率因數(shù)PF為1，開關(guān)電源經(jīng)功率因數(shù)PF校正后可以達到0.8以上！開關(guān)電源功率因素低，會影響電網(wǎng)的使用效率，比如：10KW的電力變壓器，如果使用功率因數(shù)PF為0.6，功率1KW的開關(guān)電源，只能同時帶動6臺這樣的開關(guān)電源，如果使用功率因數(shù)PF為0.9，功率1KW的開關(guān)電源，可以同時帶動9臺這樣的開關(guān)電源！大量使用功率因素低的開關(guān)電源，會將許多功率消耗在電線上，使電線發(fā)熱。還會使電網(wǎng)的正弦波失真變形，影響其它電器的正常使用。一般大功率開關(guān)電源，都要求功率因數(shù)PF在0.8以上！對于手機充電器這樣的小功率開關(guān)電源，沒有要求。對于LED電源，有些對功率因數(shù)也有要求。天津主動式PFC電源廠家主動式PFC電路是由電感線圈、濾波電容、開關(guān)管及控制IC等元件組成的一個升壓電路。</p><div

style="text-indent:25px">開關(guān)電源pfc常見故障：保險絲熔斷：一般情況下，保險絲熔斷說明電源的內(nèi)部線路有問題。由于電源工作在高電壓、大電流的狀態(tài)下，電網(wǎng)電壓的波動、浪涌都會引起電源內(nèi)電流瞬間增大而使保險絲熔斷。重點應(yīng)檢查電源輸入端的整流二極管，高壓濾波電解電容，逆變功率開關(guān)管等，檢查一下這此元器件有無擊穿、開路、損壞等。如果確實是保險絲熔斷，應(yīng)該首先查看電路板上的各個元件，看這些元件的外表有沒有被燒糊，有沒有電解液溢出，如果沒有發(fā)現(xiàn)上述情況，則用萬用表測量開關(guān)管有無擊穿短路。需要特別注意的是：切不可在查出某元件損壞時，更換后直接開機，這樣很有可能由于其它高壓元件仍有故障又將更換的元件損壞，一定要對上述電路的所有高壓元件進行各方面檢查測量后，才能徹底排除保險絲熔斷的故障。，</p><p style="text-indent:25px">開關(guān)電源中的pfc是什么意思？PFC的英文全稱為“Power Factor Correction”，意思是“功率因數(shù)校正”，功率因數(shù)指的是有效功率與總耗電量（視在功率）之間的關(guān)系，也就是有效功率除以總耗電量（視在功率）的比值。基本上功率因數(shù)可以衡量電力被有效利用的程度，當功率因數(shù)值越大，表示其電力利用率越高。功率因數(shù)是用來衡量用電設(shè)備用電效率的參數(shù)，低功率因數(shù)表示低電力效能。為了提高用電設(shè)備功率因數(shù)的技術(shù)就稱為功率因數(shù)校正。主動式PFC則由電感電容及電子元器件組成，體積小、通過**IC去調(diào)整電流的波形，對電流電壓間的相位差進行補償。主動式PFC可以達到較高的功率因數(shù)──通?？蛇_98%以上，但成本也相對較高。此外，主動式PFC還可用作輔助電源，因此在使用主動式PFC電路中，往往不需要待機變壓器，而且主動式PFC輸出直流電壓的紋波很小，這種電源不必采用很大容量的濾波電容。PFC還能減少電源對市電電網(wǎng)的干擾，尤其是避免它在突然啟動時對其他電器的影響。</p><div

style="text-indent:25px">pfc對電源的重要性：這里我們需要指出的是，居民用戶只需要支付實際功率（瓦數(shù)）所消耗的電量，則不會支付回流到電網(wǎng)中無用功率的電量。而對于商業(yè)工廠用電則會追加無用功率這一部分的用電，因為他們所消耗電量的基數(shù)太大了。雖然對于居民用戶來說，我們不需要支付無用功率的電費，但是根據(jù)《歐盟EN61000-3-2號標準》（當然中國也有相關(guān)的法規(guī)條款），凡是功率擦超過75W的開關(guān)電源，都需要至少安裝被動PFC模塊。此外，在80Plus電源認證中，則要求功率因數(shù)需要超過0.9，甚至更多。不過在數(shù)年前，許多的電源廠商大多都在電源產(chǎn)品中使用被動PFC模塊。而PFC模塊則是一個減少諧波電流，并且將非線性負載轉(zhuǎn)換成線性負載的過濾器，電容和電感所產(chǎn)生的功率因數(shù)則會向單位值跟近一些。“填谷電路式”屬于一種新型無源功率因數(shù)校正電路。天津主動式PFC電源廠家</p><p
