style="text-indent:25px">目前電腦用的電源PFC有兩種，一是被動式PFC，也稱無源PFC；一是主動式PFC，也稱有源式PFC。1、主動式PFC主要由高頻電感、開關(guān)管、電容以及控制IC等元件構(gòu)成，可簡單的歸納為升壓型開關(guān)電源電路，這種電路的特點是構(gòu)造復雜，但優(yōu)點很多：功率因數(shù)高達0.99、低損耗和高可靠、輸入電壓可以從90V到270V(寬幅輸入)等，由于輸出DC電壓紋波很小，因此采用主動式PFC的電源不需要采用很大容量的濾波電容。2、被動式PFC通常為一塊體積較大的電感，其內(nèi)部由多塊硅鋼片外部纏繞銅線而組成，它的原理是采用電感補償方法通過使交流輸入的基波電流與電壓之間相位差減小來提高功率因數(shù)，深圳主動式電源pfc批發(fā)哪家好，被動式PFC的功率因數(shù)不是很高，只能達到0，深圳主動式電源pfc批發(fā)哪家好.7~0.8，深圳主動式電源pfc批發(fā)哪家好，因此其效率也比較低，發(fā)熱量也比較大。被動式PFC也并非一無是處，其結(jié)構(gòu)簡單，穩(wěn)定性上表現(xiàn)好，比較適合中低端電源。3、主動式PFC設計復雜，成本較高；主動式PFC比被動式PFC性能要好，更加節(jié)能；主動式PFC的功率因數(shù)更高；被動式PFC電源成本低。正因如此，主動式PFC已成為當前電腦主流電源。如果你只是想用低端的電腦穩(wěn)定使用的話，那買個被動式PFC的電源使用沒問題。相對于被動PFC簡單直觀的外形，主動式PFC電路要復雜許多。深圳主動式電源pfc批發(fā)哪家好</p><div

style="text-indent:25px">pfc對電源的重要性：在一個純電抗負載電路中，電壓和電流之間會產(chǎn)生一定的是時間差，也就會出現(xiàn)相位差（zui大理論值為90度，一般情況多為45度），那么電壓與電流的乘積，就不一定每一時刻都為“正”了。在一個半周期內(nèi)，能量為“正”，另外一個半周期內(nèi)能量為“負”，那么就是說，前半周期電源從電網(wǎng)中獲取能量，而在后半個周期內(nèi)，這些能量又會回流到國家電網(wǎng)中。所以如果按照一個周期計算，那么電源獲得的能量會為“零”，沒有能量。上面的兩種描述都是純理論的理想狀態(tài)。但在實際應用中，電路中會有大量的電阻、電感和電容，在同一時刻都會有負載，也就會產(chǎn)生不同方向的“能量”。因此，所有的正向能量，我們稱其為“實際功率”，而反向回流電網(wǎng)的能量則稱之為“無用功率”，那么“實際功率”與“無用功率”的綜合，就是之前我們所說的“視在功率”。但正如我們之前所提到的，“功率因數(shù)”實際上就是“實際功率”與“視在功率”的比值。而zui為理想的比值為“1”，當然這還無法做到，因此只能無限接近于“1”，這個數(shù)值我們一般稱之為“功率因數(shù)”。天津PFC電腦電源報價被動式PFC通常為一塊體積較大的電感。</p><div

style="text-indent:25px">主動式PFC與被動式PFC電源的不同：在早些年主動式PFC電源剛剛步入主流的時候，商家們一度大肆宣傳“主動式就是比被動式好”，現(xiàn)在主動式PFC電源已經(jīng)成為主流，雖然不再需要像當年那樣瘋狂地推廣，但是我們?nèi)匀豢梢栽诓簧匐娫串a(chǎn)品的包裝上看到強調(diào)主動式PFC的字眼，可見這個觀點早已深入人心。那么主動式PFC相比被動式PFC好在哪里呢？現(xiàn)在我們就來一起探討一下被動式PFC與主動式PFC之間差異，看看為什么主動式PFC電源能夠成為現(xiàn)在的主流?，F(xiàn)在主動式PFC已經(jīng)成為主流和高級電源的標配。</p><p style="text-indent:25px">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。為了提高用電設備功率因數(shù)的技術(shù)就稱為功率因數(shù)校正。計算機開關(guān)電源是一種電容輸入型電路，其電流和電壓之間的相位差會造成交換功率的損失，此時便需要PFC電路提高功率因數(shù)。目前的PFC有兩種，一種為被動式PFC（也稱無源PFC）和主動式PFC（也稱有源式PFC）。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。</p><div

Factor），即我們PC電源評測中常提到的PF值，這是一個有效功率除以視在功率所得出來的比值。而功率因數(shù)校正即PFC（Power Factor Correction）的用作就是提升PF值，它可以起到減少脈沖電流諧波分量、降低EMI電磁干擾、降低諧波失真度等作用，從是實現(xiàn)降低電網(wǎng)污染、使功率因數(shù)趨向于1的效果。目前PC電源中有分為被動式PFC和主動式PFC，前者常見于低端電源產(chǎn)品或者是一些比較老舊的產(chǎn)品中，一般來說可以將電源的功率因數(shù)控制在0.7到0.8的范圍，但一般不會超過0.8；后者則是目前主流和高級電源的標配，它可以將電源的功率因數(shù)控制在0.9甚至更高的水平，部分高級產(chǎn)的功率因數(shù)甚至可以無限接近于1。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。深圳被動式PFC電源廠家聯(lián)系方式</p><p style="text-indent:25px">主動式PFC通過高頻電感線圈、開關(guān)電子管、高壓濾波電容以及控制IC等元件，組成一個電路。深圳主動式電源pfc批發(fā)哪家好</p><p 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。，深圳主動式電源pfc批發(fā)哪家好</p><p
