style="text-indent:25px">PC電源為什么需要配置PFC電路？目前電路負載基本上可以分為兩種模式，其一為電阻型負載，這種負載在采用交流輸入時，其電壓與電流的波形都將呈現(xiàn)正弦曲線且相位相同，換句話說電壓和電流都會在同一時刻逆轉(zhuǎn)極性，能量一直為正向移動；另外一種則是電抗型負載，這種負載在采用交流輸入時雖然電壓與電流的波形同樣為正弦曲線，但兩個波形之間存在相位差，這樣就無法保證電壓與電流在每一個時刻都是相同的極性，在極性相反的周期內(nèi)，能量是反向移動。由于電壓與電流波形之間存在相位差，因此會有反向能量即無效功率的產(chǎn)生。當(dāng)然這兩種都是理想狀態(tài)下的負載，在實際應(yīng)用中其實是電阻性負載與電抗型負載的混合，極少存在單一型負載的情況，因此在任意時刻的負載中會有兩種不同方向的能量，其中只有正向能量是有價值的，我們將其稱為有效功率，反向能量則稱為無效功率，而兩者的綜合就是視在功率了。成都電源pfc批發(fā)價格PFC分為主動式（有源）和被動式（無源）兩種。</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）。</p><p style="text-indent:25px">主動式PFC電源會更省電嗎？在主動式PFC電源剛剛步入主流的時候，不少廠商為了宣傳自家的主動式PFC電源產(chǎn)品，都紛紛打出了“主動式PFC電源更加省電”的旗幟，引導(dǎo)消費者選擇采用主動式PFC設(shè)計的產(chǎn)品。但事實上是不是這樣呢？主動式PFC電源就一定比被動式PFC電源省電嗎？如果從宏觀的角度來看，確實是這樣沒錯的。同樣是200W的有效功率，采用被動式PFC設(shè)計、PF值為0.8的PC電源需要消耗250W的視在功率，而采用主動式PFC設(shè)計、PF值為0.9的PC電源則只需要222W的視在功率，如果說視在功率相當(dāng)于發(fā)電機的輸出功率，那主動式PFC電源對發(fā)電機造成的負荷就更低，自然也就是更省電了。然而這樣的省電對于消費者而言并沒有什么實際意義，因為我們的電表只統(tǒng)計有效功率，并不是統(tǒng)計視在功率，換句話說你只需要為有效功率付電費，因此不管是主動式PFC、被動式PFC還是沒有PFC，只要有效功率相同，電表上走的數(shù)字就是相同的，消費者需要支付的電費也是相同的。真正能讓你省電費的參數(shù)是電源的轉(zhuǎn)換效率，這個轉(zhuǎn)換效率直接影響電源有效功率的高低，在相同的輸出負載下，轉(zhuǎn)換效率更高的電源所需要的有效功率越低，你需要付的電費自然也越少了。有些電源在待機時發(fā)出高頻噪音，也是因為主動PFC。</p><div

style="text-indent:25px">被動式PFC的缺點：1、當(dāng)歐洲EN的諧波規(guī)范越來越嚴格時，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)器在運輸過程損壞的風(fēng)險。3、原料短缺的風(fēng)險較高。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，因為有更多的電能并沒有被實際負載利用上。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。深圳被動式PFC電源廠家聯(lián)系方式</p><p
