Factor Corrector，意思是功率因數(shù)校正器，它可以在交流轉(zhuǎn)換為直流時(shí)提高電源對(duì)市電的利用率，但不能減小轉(zhuǎn)換過(guò)程的電能損耗，也沒(méi)有節(jié)約電能的功能。此外，PFC還能減少電源對(duì)市電電網(wǎng)的干擾，尤其是避免它在突然啟動(dòng)時(shí)對(duì)其他電器的影響。PFC分為主動(dòng)式（有源）和被動(dòng)式（無(wú)源）兩種，它們是衡量電源檔次高低的一個(gè)重要因素。一般來(lái)說(shuō)，功率在250W～300W的電源多采用被動(dòng)式PFC，而主動(dòng)式PFC則常用于400W及以上的中高級(jí)電源。就性能而言，主動(dòng)式PFC擁有更高的功率因數(shù)（高達(dá)99%），配合好的電路設(shè)計(jì)，能適應(yīng)更高的電壓范圍。你可以通過(guò)電源散熱孔查看該產(chǎn)品采用了何種PFC電路：被動(dòng)式PFC通常為一塊體積較大的電感，由多塊硅鋼片外部纏繞銅線而成；而主動(dòng)式PFC則由電感線圈配合IC控制芯片組成。成都主動(dòng)式PFC電源銷售廠家主動(dòng)PFC在低功率時(shí)，自身?yè)p耗大于被動(dòng)PFC。</p><div

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(lái)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。簡(jiǎn)介：計(jì)算機(jī)開(kāi)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(huì)造成交換功率的損失，此時(shí)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(dòng)式PFC（也稱無(wú)源PFC）和主動(dòng)式PFC（也稱有源式PFC）。</p><p style="text-indent:25px">電源里主動(dòng)PFC和被動(dòng)PFC有什么區(qū)別：同樣額定功率的電源產(chǎn)品，主動(dòng)式PFC電源大部分有著比被動(dòng)式PFC產(chǎn)品更高的轉(zhuǎn)換效率，因?yàn)榍罢咄谧龉?、用料和架?gòu)上都會(huì)有更高的水平，品質(zhì)也會(huì)更好，所以主動(dòng)式PFC電源產(chǎn)品在客觀上更省電費(fèi)。主動(dòng)式PFC電源對(duì)交流輸入電壓的適應(yīng)性也更強(qiáng)，基本上目前的寬幅電源都采用了主動(dòng)式PFC設(shè)計(jì)，這樣在電壓波動(dòng)比較大環(huán)境下，主動(dòng)式PFC電源仍然可以保持穩(wěn)定的輸出。而被動(dòng)式PFC電源對(duì)輸入電壓的穩(wěn)定性有一定的要求，電壓浮動(dòng)的適應(yīng)范圍往往不如主動(dòng)式PFC產(chǎn)品，在輸入電壓起伏較大的環(huán)境下可能無(wú)法正常工作?！半姼醒a(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)。</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，電磁干擾小；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。PFC的全稱是Power Factor Corrector。北京被動(dòng)式PFC電源廠家推薦</p><p style="text-indent:25px">主動(dòng)式PFC擁有更高的功率因數(shù)（高達(dá)99%）。成都主動(dòng)式PFC電源銷售廠家</p><p style="text-indent:25px">如何快速維修pfc電路：8、主開(kāi)關(guān)電壓+24V或+12 V的輸出電流較大，對(duì)整流二極管要求較高，一般采用低壓差的大功率肖特基二極管，不能用普通的整流二極管替換。另外接負(fù)載后，電壓反而上升，多屬于電源濾波不好引起。9、電源帶負(fù)載能力差，首先要測(cè)一下PFC 電壓是否正常（380 v），如果正常，問(wèn)題就在電源厚膜上，通常是電源厚膜帶載能力差引起，這一點(diǎn)請(qǐng)大家注意。10、電源板上，貼有**三角形標(biāo)記的散熱片以及散熱片下面的電路，均為熱地。嚴(yán)謹(jǐn)直接用手接觸！注意任何檢測(cè)設(shè)備，都不能直接跨接在熱地和冷地之間。成都主動(dòng)式PFC電源銷售廠家</p><p
