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(dāng)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。計(jì)算機(jī)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）。合肥被動式電源pfc主動PFC為了搞定電磁干擾，EMI濾波電路要加強(qiáng)，電路更加復(fù)雜。</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(dāng)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(qiáng)調(diào)主動式PFC的字眼，可見這個觀點(diǎn)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(biāo)配。</p><p 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(shí)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?yàn)樗麄兯碾娏康幕鶖?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(fèi)，但是根據(jù)《歐盟EN61000-3-2號標(biāo)準(zhǔn)》（當(dāng)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(rèn)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(fù)載轉(zhuǎn)換成線性負(fù)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。在PFC開關(guān)電源當(dāng)中，開關(guān)穩(wěn)壓電源是非常重要的一個組成部分。</p><div
