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(hào)通過濾波電容，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，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，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，濟(jì)南主動(dòng)PFC電源批發(fā)價(jià)格，主動(dòng)式PFC也有凌駕于被動(dòng)式PFC，可以輕松達(dá)到0，濟(jì)南主動(dòng)PFC電源批發(fā)價(jià)格.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，濟(jì)南主動(dòng)PFC電源批發(fā)價(jià)格，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(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。濟(jì)南主動(dòng)PFC電源批發(fā)價(jià)格</p><div

12V和+5V電壓的過壓、過載保護(hù)電路，其保護(hù)電路多采用四運(yùn)算放大器LM324、四電壓比較器LM339、雙電壓比較器LM393或雙運(yùn)算放大器LM358。過流過壓保護(hù)電路，在維修時(shí)可脫開不用，如果電壓恢復(fù)正常，說明保護(hù)電路引起，這時(shí)要分步斷開是哪路起作用。然后再進(jìn)行維修。7、開機(jī)前，先確認(rèn)有無(wú)炸件、電容鼓包現(xiàn)象，如有應(yīng)先更換并把相關(guān)的器件全部都測(cè)量一遍。建議更換所有損壞器件后試機(jī)時(shí)，zui好把原機(jī)保險(xiǎn)絲除掉; 接上一個(gè)220V/100W的燈泡，這樣可以有效防止再次炸件。目前電路負(fù)載基本上可以分為兩種模式，其一為電阻型負(fù)載，另外一種則是電抗型負(fù)載。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"

style="text-indent:25px">電感補(bǔ)償式的被動(dòng)式PFC有結(jié)構(gòu)簡(jiǎn)單、成本低廉的優(yōu)勢(shì)，但是其電感的體積和重量都會(huì)隨著電源額定功率的提升而增加，因此被動(dòng)式PFC基本上不會(huì)用在額定功率比較高的電源產(chǎn)品中。另外由于被動(dòng)式PFC電源往往有著比較高的重量，因此在玩家群體里產(chǎn)生了一種“電源越重品質(zhì)越好”的判斷方法，這個(gè)判斷法一直沿用至今，雖然現(xiàn)在基本已經(jīng)沒有實(shí)用價(jià)值，但仍然被不少剛?cè)腴T的玩家奉為信條。值得一提的是，由于有這樣的判斷法，在被動(dòng)式PFC電源仍是主流的年代，有不少假冒偽劣產(chǎn)品會(huì)采用假的PFC電感，這些電感在表面上和真品沒什么區(qū)別，但實(shí)際上可能只有硅鋼片而沒有銅線繞圈，甚至只是灌裝水泥冒充的，以增加電源的重量。因此“電源越重品質(zhì)越好”的判斷方法就算有些參考意義，但顯然不會(huì)是一定的判斷標(biāo)準(zhǔn)。采用假PFC的電源，其PF值只有0.5到0.6的水平。此外被動(dòng)式PFC電源對(duì)輸入電壓的穩(wěn)定性有一定的要求，基本上電壓波動(dòng)的允許范圍不會(huì)太廣。而且由于被動(dòng)式PFC適合在比較高的電壓下使用，因此采用110V輸入設(shè)計(jì)的被動(dòng)式PFC電源還需要添加一個(gè)倍壓器，將輸入電壓從110V增加至220V，以保證PFC電路工作的正常。PFC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。天津電源pfc批發(fā)</p><p

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(shí)提高電源對(duì)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(duì)市電電網(wǎng)的干擾，尤其是避免它在突然啟動(dòng)時(shí)對(duì)其他電器的影響。PFC分為主動(dòng)式（有源）和被動(dòng)式（無(wú)源）兩種，它們是衡量電源檔次高低的一個(gè)重要因素。一般來(lái)說，功率在250W～300W的電源多采用被動(dòng)式PFC，而主動(dòng)式PFC則常用于400W及以上的中高級(jí)電源。就性能而言，主動(dòng)式PFC擁有更高的功率因數(shù)（高達(dá)99%），配合好的電路設(shè)計(jì)，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(dòng)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(dòng)式PFC則由電感線圈配合IC控制芯片組成。濟(jì)南主動(dòng)PFC電源批發(fā)價(jià)格</p><p
