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(gè)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(gè)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，青島PFC電源廠家，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，青島PFC電源廠家，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，青島PFC電源廠家，也是出于降低能耗的考慮。計(jì)算機(jī)開關(guān)電源是一種電容輸入型電路。青島PFC電源廠家</p><div

style="text-indent:25px">電源里主動PFC和被動PFC有什么區(qū)別：同樣額定功率的電源產(chǎn)品，主動式PFC電源大部分有著比被動式PFC產(chǎn)品更高的轉(zhuǎn)換效率，因?yàn)榍罢咄谧龉?、用料和架?gòu)上都會有更高的水平，品質(zhì)也會更好，所以主動式PFC電源產(chǎn)品在客觀上更省電費(fèi)。主動式PFC電源對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式PFC設(shè)計(jì)，這樣在電壓波動比較大環(huán)境下，主動式PFC電源仍然可以保持穩(wěn)定的輸出。而被動式PFC電源對輸入電壓的穩(wěn)定性有一定的要求，電壓浮動的適應(yīng)范圍往往不如主動式PFC產(chǎn)品，在輸入電壓起伏較大的環(huán)境下可能無法正常工作。上海被動式電源pfc批發(fā)“填谷電路式”的特點(diǎn)是利用整流橋后面的填谷電路來大幅度增加整流管的導(dǎo)通角。</p><div

style="text-indent:25px">主動式PFC與被動式PFC電源的不同：在早些年主動式PFC電源剛剛步入主流的時(shí)候，商家們一度大肆宣傳“主動式就是比被動式好”，現(xiàn)在主動式PFC電源已經(jīng)成為主流，雖然不再需要像當(dāng)年那樣瘋狂地推廣，但是我們?nèi)匀豢梢栽诓簧匐娫串a(chǎn)品的包裝上看到強(qiáng)調(diào)主動式PFC的字眼，可見這個(gè)觀點(diǎn)早已深入人心。那么主動式PFC相比被動式PFC好在哪里呢？現(xiàn)在我們就來一起探討一下被動式PFC與主動式PFC之間差異，看看為什么主動式PFC電源能夠成為現(xiàn)在的主流?，F(xiàn)在主動式PFC已經(jīng)成為主流和高級電源的標(biāo)配。</p><p style="text-indent:25px">被動式PFC的缺點(diǎn)：1、當(dāng)歐洲EN的諧波規(guī)范越來越嚴(yán)格時(shí)，電感量產(chǎn)的質(zhì)量需提升，而生產(chǎn)難度將提高。2、沉重重量增加電源供應(yīng)器在運(yùn)輸過程損壞的風(fēng)險(xiǎn)。3、原料短缺的風(fēng)險(xiǎn)較高。4、如電源內(nèi)部結(jié)構(gòu)固定的不正確，容易產(chǎn)生震動噪音。5、當(dāng)電源供應(yīng)器輸出超過300瓦以上，被動式PFC在材料成本及產(chǎn)品性能表現(xiàn)上將越不具競爭力。PFC作為決定電源轉(zhuǎn)換效率的重要因素，其主要分為主動PFC與被動PFC。前者帶來的是更高的功率因數(shù)但成本也會有很大的增加，后者雖然價(jià)格低廉但功率因數(shù)也會有所下降。主動PFC電路本身損耗的電能比起被動PFC電路更高，從而直接降低了電源的轉(zhuǎn)換效率，因?yàn)橛懈嗟碾娔懿]有被實(shí)際負(fù)載利用上。PFC電路所調(diào)節(jié)的功率因數(shù)，是給電廠節(jié)省了電能，而并沒有真正給用戶節(jié)省。相對于被動PFC簡單直觀的外形，主動式PFC電路要復(fù)雜許多。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="青島PFC電源廠家,PFC電源"

style="text-indent:25px">被動式PFC，不論靜音與否，他們都可以被稱作無源PFC。無源PFC一般采用電感補(bǔ)償方法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)，但無源PFC的功率因數(shù)不是很高，只能達(dá)到0.7~0.8。靜音型被動PFC相比非靜音型被動PFC，無論是成本上還是制造工藝上要求都比較高。這里還要說明的是，PFC會產(chǎn)生噪聲的原因。從原理上講，我們在上面看到的部分結(jié)構(gòu)上和電感類似，在對電流和電壓補(bǔ)償?shù)倪^程中，始終進(jìn)行著充放電的過程，因而產(chǎn)生了磁性，zui終會和周邊的金屬元件產(chǎn)生震動進(jìn)而發(fā)出噪音。靜音型PFC相當(dāng)于兩個(gè)非靜音型PFC的疊加，達(dá)到震動互相抵消的目的。但是，在消除噪音的手段中，安裝是否得當(dāng)也是對靜音效果影響較大的因素?！】傮w上來說，非靜音型被動PFC與靜音型被動PFC所能達(dá)到的效果大致相當(dāng)，但都要低于主動式PFC的功因校正效果?！半姼醒a(bǔ)償式”包括靜音式和非靜音式。成都主動PFC電源批發(fā)哪家好</p><p style="text-indent:25px">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。青島PFC電源廠家</p><p style="text-indent:25px">主動式PFC的特點(diǎn)及總結(jié)：接下來我們就是看看采用主動式PFC設(shè)計(jì)電源的功率因數(shù)變化了。這次我們選擇了游戲悍將紅紫銀效R500M電源和游戲引擎UT-450AP電源的功率因數(shù)變化來看一下。這兩款電源都采用了主動式PFC設(shè)計(jì)，他們的功率因數(shù)zui高都超過了99%，這說明了他們在節(jié)能方面還是非常出色的。通過我們對主動式PFC設(shè)計(jì)的分析介紹，可以得出以下幾點(diǎn)：1、主動式PFC設(shè)計(jì)復(fù)雜，成本較高。2、主動式PFC比被動式PFC性能要好，更加節(jié)能。3、主動式PFC的功率因數(shù)zui高能超過99%。4、主動式PFC能適應(yīng)更高的電壓范圍。青島PFC電源廠家</p><p
