style="text-indent:25px">FC分為被動式PFC和主動式PFC，那么主動式PFC和被動式PFC都有哪些區(qū)別呢？目前市場上功率在250W～300W的電源多采用被動式PFC，而主動式PFC則常用于400W及以上電源，他們的造型結(jié)構(gòu)也是不太一樣的。接下來我們就來看看他們各自的結(jié)構(gòu)造型吧。一般情況下，被動式PFC的電感體積較大，它由多塊硅鋼片外部纏繞銅線而成。這種設(shè)計結(jié)構(gòu)簡單，成本較低。而主動式PFC則是電感線圈，另外它還要配合有IC控制芯片，這種設(shè)計結(jié)構(gòu)復(fù)雜，成本是比較高的。被動式的主電容一般采用兩個巨大的電解電容，這種電容的生產(chǎn)成本較低，相對于主動式PFC來說，可以節(jié)省不少的生產(chǎn)成本。上面主動式PFC與被動式PFC的對比，在我們看來，好像被動式PFC的優(yōu)勢要明顯一些。不過，被動式PFC卻有著一個致命的缺陷，那就是在高功率電源中，主動式PFC要比被動式PFC省電許多。而且，它能適應(yīng)更高的電壓范圍。</p><p style="text-indent:25px">PFC就是功率因數(shù)校正的意思，主要用來表征電子產(chǎn)品對電能的利用效率。功率因數(shù)越高，說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，國際電工委員會制訂了IEC55－2限制高次諧波的規(guī)范（后來的修訂規(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，就可以較大提高對電能的利用效率。主動式PFC配合好的電路設(shè)計，能適應(yīng)更高的電壓范圍。</p><div

style="text-indent:25px">目前電腦用的電源PFC有兩種，一是被動式PFC，也稱無源PFC；一是主動式PFC，也稱有源式PFC。1、主動式PFC主要由高頻電感、開關(guān)管、電容以及控制IC等元件構(gòu)成，可簡單的歸納為升壓型開關(guān)電源電路，這種電路的特點是構(gòu)造復(fù)雜，但優(yōu)點很多：功率因數(shù)高達(dá)0.99、低損耗和高可靠、輸入電壓可以從90V到270V(寬幅輸入)等，由于輸出DC電壓紋波很小，因此采用主動式PFC的電源不需要采用很大容量的濾波電容。2、被動式PFC通常為一塊體積較大的電感，其內(nèi)部由多塊硅鋼片外部纏繞銅線而組成，它的原理是采用電感補償方法通過使交流輸入的基波電流與電壓之間相位差減小來提高功率因數(shù)，被動式PFC的功率因數(shù)不是很高，只能達(dá)到0.7~0.8，因此其效率也比較低，發(fā)熱量也比較大。被動式PFC也并非一無是處，其結(jié)構(gòu)簡單，穩(wěn)定性上表現(xiàn)好，比較適合中低端電源。3、主動式PFC設(shè)計復(fù)雜，成本較高；主動式PFC比被動式PFC性能要好，更加節(jié)能；主動式PFC的功率因數(shù)更高；被動式PFC電源成本低。正因如此，主動式PFC已成為當(dāng)前電腦主流電源。如果你只是想用低端的電腦穩(wěn)定使用的話，那買個被動式PFC的電源使用沒問題。主動PFC為了搞定電磁干擾，EMI濾波電路要加強，電路更加復(fù)雜。廣州PFC電腦電源銷售</p><p style="text-indent:25px">普通的開關(guān)穩(wěn)壓電源需要220V整流供電，而PFC穩(wěn)壓開關(guān)電源是由B+PFC供電。濟(jì)南PFC電源價格</p><p style="text-indent:25px">主動式PFC和被動式PFC電源共同與不同之處簡單地說，主動式PFC就是一個有源的升壓電路。它通過高頻電感線圈、開關(guān)電子管、高壓濾波電容以及控制IC等元件，組成一個可以將輸入電壓提高的電路，通過升高輸入電壓來減少電流在流向下級電路中的電能損耗。為什么升高輸入電壓會減少電能損耗呢？我們知道，功率P=UI，在電網(wǎng)的輸入總功率P一定的情況下，只要提高電壓，電流值就會變小，從而降低電路的電能損耗。我們國家的電網(wǎng)系統(tǒng)之所以要采用高壓電線來傳輸電能，也是出于降低能耗的考慮。濟(jì)南PFC電源價格</p></p><br
