style="text-indent:25px">主動式PFC的一般結(jié)構(gòu)：主動式PFC一般由功率MOFET開關(guān)管、PFC二極管、電感、濾波電容和NTC熱敏電阻以及IC整合電路六個電子元器件組成。下面我們就來看看這些配置吧。主電容及IC整合電路：主動式PFC電路的設(shè)計還是比較復(fù)雜的，這無形之中就增加了電源的制作成本，因此在市場上，采用主動式PFC電路設(shè)計的電源給消費者的感覺就是價格比較高。雖然說主動式PFC電路設(shè)計比較復(fù)雜，成本也比較高，但是它帶來的效益還是不可估量的，zui重要的是，它能適應(yīng)更高的電壓范圍，這對于玩家來說是非常關(guān)鍵的。北京主動式PFC電源多少錢主動式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。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="北京主動式PFC電源多少錢,PFC電源"

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。</p><p style="text-indent:25px">電源里主動PFC和被動PFC有什么區(qū)別：有源和無源的區(qū)別。PFC的全稱是Power Factor Corrector，意思是功率因數(shù)校正器，它可以在交流轉(zhuǎn)換為直流時提高電源對市電的利用率，但不能減小轉(zhuǎn)換過程的電能損耗，也沒有節(jié)約電能的功能。此外，PFC還能減少電源對市電電網(wǎng)的干擾，尤其是避免它在突然啟動時對其他電器的影響。PFC分為主動式（有源）和被動式（無源）兩種，它們是衡量電源檔次高低的一個重要因素。一般來說，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及以上的中高級電源。就性能而言，主動式PFC擁有更高的功率因數(shù)（高達99%），配合好的電路設(shè)計，能適應(yīng)更高的電壓范圍。你可以通過電源散熱孔查看該產(chǎn)品采用了何種PFC電路：被動式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；而主動式PFC則由電感線圈配合IC控制芯片組成。PFC可以在交流轉(zhuǎn)換為直流時提高電源對市電的利用率。</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。計算機開關(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造成交換功率的損失，此時便需要PFC電路提高功率因數(shù)。目前的PFC有兩種，一種為被動式PFC（也稱無源PFC）和主動式PFC（也稱有源式PFC）。主動式PFC可以達到較高的功率因數(shù)──通常可達98%以上，但成本也相對較高。北京主動式PFC電源多少錢</p><p
