style="text-indent:25px">什么是被動(dòng)式PFC？被動(dòng)式PFC曾經(jīng)是PC電源上的主流，現(xiàn)在雖然已經(jīng)退出主流市場(chǎng)，但由于相對(duì)低廉的成本，因此其仍然活躍在額定功率400W以下的入門(mén)級(jí)電源產(chǎn)品中。被動(dòng)式PFC電源的PF值大多在0.7到0.8左右，但甚少能有超過(guò)0.8的水平，畢竟要在被動(dòng)式PFC電源上做到PF值0.8以上，從成本來(lái)說(shuō)足以做主動(dòng)式PFC電源，后者的PF值可以輕松達(dá)到0.9的水平。常見(jiàn)于PC電源中的被動(dòng)式PFC是電感補(bǔ)償式，其通過(guò)減少交流輸入的基波電流與電壓之間相位差來(lái)提高功率因數(shù)，特點(diǎn)是在高壓濾波電容附近有一個(gè)PFC電感，這個(gè)電感由多塊硅鋼片外部纏繞銅線而成，體積大、重量高，為了保證其安裝穩(wěn)固，現(xiàn)在不少被動(dòng)式PFC電源會(huì)把PFC電感固定在外殼，再通過(guò)導(dǎo)線連接到主PCB上。</p><p style="text-indent:25px">被動(dòng)式PFC：被動(dòng)式PFC一般分“電感補(bǔ)償式”和“填谷電路式(Valley Fill Circuit)”“電感補(bǔ)償式”是使交流輸入的基波電流與電壓之間相位差減小來(lái)提高功率因數(shù)，“電感補(bǔ)償式”包括靜音式和非靜音式。“電感補(bǔ)償式”的功率因數(shù)只能達(dá)到0.7～0.8，它一般在高壓濾波電容附近?！疤罟入娐肥健睂儆谝环N新型無(wú)源功率因數(shù)校正電路，其特點(diǎn)是利用整流橋后面的填谷電路來(lái)大幅度增加整流管的導(dǎo)通角，通過(guò)填平谷點(diǎn)，使輸入電流從尖峰脈沖變?yōu)榻咏谡也ǖ牟ㄐ?，將功率因?shù)提高到0.9左右，明顯降低總諧波失真。與傳統(tǒng)的電感式無(wú)源功率因數(shù)校正電路相比，其優(yōu)點(diǎn)是電路簡(jiǎn)單，功率因數(shù)補(bǔ)償效果明顯，并且在輸入電路中不需要使用體積大重量沉的大電感器。主動(dòng)式PFC：而主動(dòng)式PFC則由電感電容及電子元器件組成，體積小、通過(guò)**IC去調(diào)整電流的波形，對(duì)電流電壓間的相位差進(jìn)行補(bǔ)償。主動(dòng)式PFC可以達(dá)到較高的功率因數(shù)──通常可達(dá)98%以上，但成本也相對(duì)較高。此外，主動(dòng)式PFC還可用作輔助電源，因此在使用主動(dòng)式PFC電路中，往往不需要待機(jī)變壓器，而且主動(dòng)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。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

style="text-indent:25px">常見(jiàn)的PFC電路分為兩種，一種是主動(dòng)式PFC電路，另一種是被動(dòng)式PFC電路。主動(dòng)式PFC電路是一種特殊的Boost斬波電路，220V市電經(jīng)過(guò)二極管整流后不使用電容來(lái)濾波，而是直接送入主動(dòng)式PFC電路中進(jìn)行升壓，借助PFC電路來(lái)完成了濾波這個(gè)環(huán)節(jié)直接輸出高壓直流電（一般在350V以上）給開(kāi)關(guān)電源電路使用。主動(dòng)式PFC的優(yōu)點(diǎn)很多，比如它改善功率因數(shù)的效果很明顯，可以將電腦電源的功率因數(shù)提高到0.98以上；其次主動(dòng)式PFC還能夠改擴(kuò)寬輸入電壓范圍，從而制成寬電壓輸入的電源。主動(dòng)式PFC的缺點(diǎn)是電路較為復(fù)雜，成本較高。被動(dòng)式PFC電路實(shí)際上只有一個(gè)大的鐵芯電感組成，這個(gè)電感串聯(lián)在整流電路與濾波電容之間，電路很簡(jiǎn)潔，利用電感電流不能突變的原理來(lái)改善輸入交流電流的波形從而提高功率因數(shù)。它的優(yōu)點(diǎn)是成本低，電路簡(jiǎn)單，可靠性高，電磁干擾??；缺點(diǎn)是提升功率因數(shù)的效果有限，一般只能達(dá)到0.8左右。主動(dòng)式PFC體積小、通過(guò)**IC去調(diào)整電流的波形，對(duì)電流電壓間的相位差進(jìn)行補(bǔ)償。上海被動(dòng)式PFC電源采購(gòu)</p><p
