style="text-indent:25px">什么是主動(dòng)式PFC？主動(dòng)式PFC在結(jié)構(gòu)上來說基本就是一個(gè)通過PWM控制電流波形的AC/DC整流器，交流輸入通過整流橋進(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，隨后這些脈沖信號通過濾波電容，將相對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)體積相對較大的電感線圈，這個(gè)電感線圈可以對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)上來說，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。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，部分高級產(chǎn)品甚至可以實(shí)現(xiàn)無限接近于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，其在體積和重量上的變化也不會很大，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。</p><p style="text-indent:25px">主動(dòng)PFC電路由高頻電感、開關(guān)管、電容以及控制IC等元件構(gòu)成。電路的特點(diǎn)是構(gòu)造復(fù)雜，但優(yōu)點(diǎn)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(dòng)式PFC的電源不需要采用很大容量的濾波電容。被動(dòng)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。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(dòng)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。希望你根本個(gè)人的實(shí)際情況選擇！“功率因數(shù)校正”，通俗的話說，就是提高有用功的比重。</p><div

Factor），即我們PC電源評測中常提到的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，一般來說可以將電源的功率因數(shù)控制在0.7到0.8的范圍，但一般不會超過0.8；后者則是目前主流和高級電源的標(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，部分高級產(chǎn)的功率因數(shù)甚至可以無限接近于1。在PFC開關(guān)電源當(dāng)中，開關(guān)穩(wěn)壓電源是非常重要的一個(gè)組成部分。武漢被動(dòng)式PFC電源批發(fā)</p><p style="text-indent:25px">主動(dòng)式PFC還可用作輔助電源，因此在使用主動(dòng)式PFC電路中，往往不需要待機(jī)變壓器。武漢被動(dòng)式PFC電源批發(fā)</p><p style="text-indent:25px">未來公共環(huán)境下的銷售肯定需要更多方面的支持，如支付寶、城市一卡通、銀聯(lián)卡等。要明白，在當(dāng)下不同的支付方式用以滿足不同消費(fèi)群體的要求。此外，也需要開發(fā)更多值服務(wù)業(yè)務(wù)，從固定服務(wù)延伸到相關(guān)服務(wù)。而且，由于UPS/EPS電源，雙向逆變器，安防電源，激光儲能電源產(chǎn)品的大部分都處于戶外且無人值守的工作環(huán)境，再加上用戶對相關(guān)設(shè)備違規(guī)操作，致使相關(guān)的行業(yè)及產(chǎn)品也在面臨嚴(yán)重的安全問題。UPS/EPS電源，雙向逆變器，安防電源，激光儲能電源曾被三星在內(nèi)的手機(jī)廠商視為超越蘋果的一大賣點(diǎn)，然而看起來目前UPS/EPS電源，雙向逆變器，安防電源，激光儲能電源功能并非剛需和標(biāo)配。雖然看上去市場進(jìn)展緩慢，但實(shí)際上經(jīng)過這幾年的發(fā)展，市場正處于一個(gè)高速發(fā)展的階段。因此，出于效益、技術(shù)、資源、勞動(dòng)力成本等諸多方面的考慮，世界不少發(fā)達(dá)地區(qū)的電氣設(shè)備、電源產(chǎn)品、逆變器，UPS，通訊電源，儲能電源產(chǎn)品、工業(yè)電源、電池充放電電源設(shè)備、電池充放電管理系統(tǒng)設(shè)備、數(shù)字電源、無功補(bǔ)償器或者功率矯正器、數(shù)字控制技術(shù)軟件、工業(yè)控制軟件、電力計(jì)量產(chǎn)品、新能源設(shè)備、太陽能、并網(wǎng)逆變器、離網(wǎng)逆變器、匯流箱、控制器，通訊設(shè)備產(chǎn)品、節(jié)能電子產(chǎn)品、回饋式電源負(fù)載的研發(fā)、銷售及相關(guān)信息咨詢。正在向中國轉(zhuǎn)移，不斷以獨(dú)資或合資的形式參與競爭，外國公司在國內(nèi)不同形式的企業(yè)，辦事處和電氣設(shè)備、電源產(chǎn)品、逆變器，UPS，通訊電源，儲能電源產(chǎn)品、工業(yè)電源、電池充放電電源設(shè)備、電池充放電管理系統(tǒng)設(shè)備、數(shù)字電源、無功補(bǔ)償器或者功率矯正器、數(shù)字控制技術(shù)軟件、工業(yè)控制軟件、電力計(jì)量產(chǎn)品、新能源設(shè)備、太陽能、并網(wǎng)逆變器、離網(wǎng)逆變器、匯流箱、控制器，通訊設(shè)備產(chǎn)品、節(jié)能電子產(chǎn)品、回饋式電源負(fù)載的研發(fā)、銷售及相關(guān)信息咨詢。的機(jī)構(gòu)也越來越多，使得國內(nèi)市場競爭更趨激烈。武漢被動(dòng)式PFC電源批發(fā)</p><p
