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(yīng)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(dāng)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)”。</p><p style="text-indent:25px">主動式PFC和被動式PFC電源共同與不同之處簡單地說，主動式PFC就是一個有源的升壓電路。它通過高頻電感線圈、開關(guān)電子管、高壓濾波電容以及控制IC等元件，組成一個可以將輸入電壓提高的電路，通過升高輸入電壓來減少電流在流向下級電路中的電能損耗。為什么升高輸入電壓會減少電能損耗呢？我們知道，功率P=UI，在電網(wǎng)的輸入總功率P一定的情況下，只要提高電壓，電流值就會變小，從而降低電路的電能損耗。我們國家的電網(wǎng)系統(tǒng)之所以要采用高壓電線來傳輸電能，也是出于降低能耗的考慮。PFC不能減小轉(zhuǎn)換過程的電能損耗，也沒有節(jié)約電能的功能。</p><div

style="text-indent:25px">PFC電路原理?PFC就是“功率因數(shù)”的意思，主要用來表征電子產(chǎn)品對電能的利用效率。功率因數(shù)越高，說明電能的利用效率越高。?PFC有兩種，一種是無源PFC（也稱被動式PFC），一種是有源PFC（也稱主動式PFC）。無源PFC一般采用電感補償方法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)，但無源PFC的功率因數(shù)不是很高，只能達到0.7~0.8；有源PFC由電感電容及電子元器件組成，體積小，可以達到很高的功率因數(shù)，但成本要高出無源PFC一些。?有源PFC電路中往往采用高集成度的IC，采用有源PFC電路的PC電源，至少具有以下特點：?（1）?輸入電壓可以從90V到270V；（?2）?高于0.99的線路功率因數(shù)，并具有低損耗和高可靠等優(yōu)點；?（3）?IC的PFC還可用作輔助電源，因此在使用有源PFC電路中，往往不需要待機變壓器；?（4）?輸出不隨輸入電壓波動變化，因此可獲得高度穩(wěn)定的輸出電壓；?5）?有源PFC輸出DC電壓紋波很小，且呈100Hz/120Hz（工頻2倍）的正弦波，因此采用有源PFC的電源不需要采用很大容量的濾波電容。計算機開關(guān)電源是一種電容輸入型電路。合肥主動式電源pfc批發(fā)廠家</p><p style="text-indent:25px">主動PFC在低功率時，自身損耗大于被動PFC。合肥主動式電源pfc批發(fā)廠家</p><p style="text-indent:25px">無PFC電源的缺點1.主動PFC在低功率時，自身損耗大于被動PFC。畢竟它是一個復(fù)雜的電路，工作起來要消耗電能;而被動PFC就是一個電感。不過很少有人讓高級電源工作的低負載下，這個問題也就不明顯了。2.主動PFC還有一個zui麻煩的缺點：電磁干擾大。為了搞定電磁干擾，EMI濾波電路要加強，電路更加復(fù)雜。有些電源在待機時發(fā)出高頻噪音，也是因為主動PFC。3.無源PFC電路是以**電源的效率和穩(wěn)定性為代價的。很多不太懂電源人，盲目的把電源加上無源PFC電路，以為這樣就能很容易的解決電路的PF值問題了，事實上，這樣在很多時候是得不償失。4.增加一點PF值，**了電源本身的更多優(yōu)良性能，無源PFC大約有兩種方式。合肥主動式電源pfc批發(fā)廠家</p><p
