style="text-indent:25px">常見的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)過二極管整流后不使用電容來濾波，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，電路很簡潔，利用電感電流不能突變的原理來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。天津電源pfc價(jià)格“功率因數(shù)校正”，通俗的話說，就是提高有用功的比重。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="合肥主動(dòng)式電源pfc批發(fā)價(jià)格,PFC電源"

style="text-indent:25px">與被動(dòng)式PFC相比，主動(dòng)式PFC電路省去了一個(gè)較大體積的含有硅鋼片的電感，因此重量上也可能會(huì)比被動(dòng)式PFC電路輕。而作為其明顯區(qū)別就是一個(gè)電感線圈，不過卻不能因此判斷電源是否主動(dòng)式PFC，因?yàn)殡娫磧?nèi)部的電感線圈較多，沒有電路知識(shí)的人并不能加以區(qū)分。由于主動(dòng)式PFC電源PFC電路自身需要消耗一定電能，如果使用在低功率（300W以下）電源中往往不如被動(dòng)式PFC電源省電，因此在此類產(chǎn)品中并不常見。另外，因?yàn)橹鲃?dòng)式PFC電路的升壓能力，能容許較低的輸入電壓，所以適應(yīng)市電通常范圍較寬（達(dá)到110V-240V）。當(dāng)然，zui明顯的識(shí)別方式，莫過于通過產(chǎn)品外殼銘牌上的標(biāo)注來識(shí)別，有寫明“主動(dòng)式PFC”或者“AcTIve PFC”即是主動(dòng)式PFC。我們知道電源的PFC電路是為了提高電源的功率因數(shù)而設(shè)，但是“功率因數(shù)”并不就等于“轉(zhuǎn)換效率”，有人將主動(dòng)式0.99的功率因數(shù)理解為能得到99%的電源轉(zhuǎn)換效率，很顯然這是不對(duì)的。雖然兩個(gè)都是描述省電的概念，但對(duì)于電腦用戶而言，兩個(gè)概念的意義是不一樣的。</p><p style="text-indent:25px">pfc對(duì)電源的重要性：我們接下來要說的，就是主動(dòng)PFC和被動(dòng)PFC電路。被動(dòng)PFC相對(duì)主動(dòng)PFC，功率因數(shù)較低，并且被動(dòng)PFC只適用于230V高壓電網(wǎng)，對(duì)于115V低壓電網(wǎng)，被動(dòng)PFC還需要一個(gè)倍壓器以適應(yīng)電網(wǎng)規(guī)格。不過，被動(dòng)PFC比主動(dòng)PFC的效能要高！此外，在主動(dòng)PFC電路中我們還會(huì)看到一個(gè)熱敏電阻，同樣是用來限制突然涌入的電流，特別是當(dāng)電源通電以及啟動(dòng)時(shí)。主動(dòng)PFC電路通常也有兩種不同的模式，電流斷續(xù)模式DCM（Discontinuous Conduction Mode）和電流連續(xù)模式CCM（ Continuous Conduction Mode）。其中DCM是指，當(dāng)電感電流為零時(shí)，PFC的MOSFET管被開啟的工作狀態(tài)；CCM是指，電感電流始終在零以上，PFC的MOSFET管被開啟的工作狀態(tài)，因此在MOSFET管中，所有的反向恢復(fù)的能量都會(huì)被浪費(fèi)。在電源PFC電路中的第二種模式（CCM）主要被用于超過200W功率輸出的電源，因?yàn)樗軌蛱峁┫鄬?duì)較低電流噪聲峰值，這意味著高功率電源可以有效抑制電流紋波，輸出更為平順的電流。不過CCM的缺點(diǎn)是耗能較高，并且在升壓二極管關(guān)閉時(shí)，會(huì)產(chǎn)生額外EMI，所以我們經(jīng)常會(huì)看到電源整流橋后通常會(huì)增加一個(gè)X電容。主動(dòng)式PFC體積小、通過**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。</p><div

style="text-indent:25px">無PFC電源的缺點(diǎn)1.主動(dòng)PFC在低功率時(shí)，自身損耗大于被動(dòng)PFC。畢竟它是一個(gè)復(fù)雜的電路，工作起來要消耗電能;而被動(dòng)PFC就是一個(gè)電感。不過很少有人讓高級(jí)電源工作的低負(fù)載下，這個(gè)問題也就不明顯了。2.主動(dòng)PFC還有一個(gè)zui麻煩的缺點(diǎn)：電磁干擾大。為了搞定電磁干擾，EMI濾波電路要加強(qiáng)，電路更加復(fù)雜。有些電源在待機(jī)時(shí)發(fā)出高頻噪音，也是因?yàn)橹鲃?dòng)PFC。3.無源PFC電路是以**電源的效率和穩(wěn)定性為代價(jià)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(shí)上，這樣在很多時(shí)候是得不償失。4.增加一點(diǎn)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(dòng)式電源pfc批發(fā)價(jià)格</p><p
