style="text-indent:25px">什么是主動(dòng)式PFC？主動(dòng)式PFC在結(jié)構(gòu)上來(lái)說(shuō)基本就是一個(gè)通過(guò)PWM控制電流波形的AC/DC整流器，交流輸入通過(guò)整流橋進(jìn)行整流，然后PWM觸發(fā)主動(dòng)PFC電路中的MosFET管，分離中間直流電壓到恒定脈沖序列，隨后這些脈沖信號(hào)通過(guò)濾波電容，將相對(duì)平順的電流送到主開關(guān)電路。此外我們可以在主動(dòng)式PFC電路中看到一個(gè)體積相對(duì)較大的電感線圈，合肥被動(dòng)式PFC電源批發(fā)價(jià)格，這個(gè)電感線圈可以對(duì)電流起到緩沖和梳理的作用，當(dāng)然它在體積和重量上比起被動(dòng)式PFC的電感要小很多。從設(shè)計(jì)結(jié)構(gòu)上來(lái)說(shuō)，主動(dòng)式PFC顯然比被動(dòng)式PFC更復(fù)雜，成本也更高。但是主動(dòng)式PFC有著更寬廣的電壓適應(yīng)能力，在電壓波動(dòng)較大的情況下仍然可以穩(wěn)定工作，不少產(chǎn)品甚至直接支持110V到220V電壓的輸入，合肥被動(dòng)式PFC電源批發(fā)價(jià)格。同時(shí)在功率因數(shù)校正的效果上，主動(dòng)式PFC也有凌駕于被動(dòng)式PFC，可以輕松達(dá)到0.9以上，部分高級(jí)產(chǎn)品甚至可以實(shí)現(xiàn)無(wú)限接近于1的效果。此外由于主動(dòng)式PFC電路的體積和重量都遠(yuǎn)小于被動(dòng)式PFC，隨著電源額定功率的提升，合肥被動(dòng)式PFC電源批發(fā)價(jià)格，其在體積和重量上的變化也不會(huì)很大，因此在被動(dòng)式PFC電源上“越重越好”的標(biāo)準(zhǔn)其實(shí)并不適合主動(dòng)式PFC電源。主動(dòng)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。合肥被動(dòng)式PFC電源批發(fā)價(jià)格</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">PFC就是功率因數(shù)校正的意思，主要用來(lái)表征電子產(chǎn)品對(duì)電能的利用效率。功率因數(shù)越高，說(shuō)明電能的利用效率越高。PC電源采用傳統(tǒng)的橋式整流、電容濾波電路會(huì)使AC輸入電流產(chǎn)生嚴(yán)重的波形畸變，向電網(wǎng)注入大量的高次諧波，因此網(wǎng)側(cè)的功率因數(shù)不高，*有0.6左右，并對(duì)電網(wǎng)和其它電氣設(shè)備造成嚴(yán)重諧波污染與干擾。早在80年代初，人們已對(duì)這類裝置產(chǎn)生的高次諧波電流所造成的危害引起了關(guān)注。1982年，國(guó)際電工委員會(huì)制訂了IEC55－2限制高次諧波的規(guī)范（后來(lái)的修訂規(guī)范是IEC1000－3－2），促使眾多的電力電子技術(shù)工作者開始了對(duì)諧波濾波和功率因數(shù)校正（PFC）技術(shù)的研究。電子電源產(chǎn)品中引入PFC電路，就可以較大提高對(duì)電能的利用效率。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。</p><div

Factor），即我們PC電源評(píng)測(cè)中常提到的PF值，這是一個(gè)有效功率除以視在功率所得出來(lái)的比值。而功率因數(shù)校正即PFC（Power Factor Correction）的用作就是提升PF值，它可以起到減少脈沖電流諧波分量、降低EMI電磁干擾、降低諧波失真度等作用，從是實(shí)現(xiàn)降低電網(wǎng)污染、使功率因數(shù)趨向于1的效果。目前PC電源中有分為被動(dòng)式PFC和主動(dòng)式PFC，前者常見(jiàn)于低端電源產(chǎn)品或者是一些比較老舊的產(chǎn)品中，一般來(lái)說(shuō)可以將電源的功率因數(shù)控制在0.7到0.8的范圍，但一般不會(huì)超過(guò)0.8；后者則是目前主流和高級(jí)電源的標(biāo)配，它可以將電源的功率因數(shù)控制在0.9甚至更高的水平，部分高級(jí)產(chǎn)的功率因數(shù)甚至可以無(wú)限接近于1。主動(dòng)式PFC配合好的電路設(shè)計(jì)，能適應(yīng)更高的電壓范圍。合肥被動(dòng)式PFC電源批發(fā)價(jià)格</p><p
