style="text-indent:25px">電源沒有pfc會(huì)有什么后果：PFC是用來提高功率因數(shù)的，在電網(wǎng)中存在有功功率和無功功率，功率因數(shù)提高后，無功功率就減少了。在我國，使用的是有功電度表，它是無法測量無功功率的，所以即使電源沒有PFC，也不會(huì)多扣電費(fèi)。但是在國外比如歐洲，它們的電度表也會(huì)計(jì)算無功功率的，沒有PFC就意味著要花更多的電費(fèi)。所以zui好買帶PFC的電源，主動(dòng)PFC電源的功率因數(shù)可以做的比較高，建議購買主動(dòng)PFC的電源。關(guān)于電壓，這個(gè)跟PFC關(guān)系不是太大，但需要注意的是，某些國家比如美國日本，它們使用的是110V交流電，那你購買電源就要購買支持100-240V全電壓的產(chǎn)品，以免到國外不能使用。電源的輸入電壓可以從電源銘牌看到，正規(guī)的支持全電壓的電源的銘牌會(huì)標(biāo)注100-240V電壓字樣，很好辨識。但是PFC就不容易從外觀看了，除非你拆開電源，簡單的辦法就是到官方網(wǎng)站查詢產(chǎn)品資料。深圳PFC電源在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。</p><div

style="text-indent:25px">pfc對電源的重要性：功率因數(shù)（PF）是指，實(shí)際功率（有效功率）與視在功率（表觀功率）的比率（kW/kVA），而我們都知道，功率P等于電壓與電流的乘積（P=V×I）。另外，在電路中會(huì)存在著zui基本的兩種電路負(fù)載，一種為“電阻（由電源中各種電阻構(gòu)成的電路負(fù)載）”，另外一種為“電抗（由電源中電感線圈和電容構(gòu)成的電路負(fù)載）”。如果整個(gè)電路都是線性負(fù)載（電路阻抗為恒定常數(shù)的負(fù)載），那么電源電壓和電流都將會(huì)呈現(xiàn)為正弦曲線，并且相位相同。而如果在這個(gè)純電阻電路中，那么電壓和電流都會(huì)在同一時(shí)刻逆轉(zhuǎn)極性，那么也就是說，在每一時(shí)刻，電壓與電流的乘積都為“正”。也就是說，在電路中，沒有“反方向（負(fù)極方向）”的能量移動(dòng)，而此時(shí)所產(chǎn)生負(fù)載功率才被稱為“實(shí)際功率”。</p><p style="text-indent:25px">常見的PFC電路分為兩種，一種是主動(dòng)式PFC電路，另一種是被動(dòng)式PFC電路。主動(dòng)式PFC電路是一種特殊的Boost斬波電路，220V市電經(jīng)過二極管整流后不使用電容來濾波，而是直接送入主動(dòng)式PFC電路中進(jìn)行升壓，借助PFC電路來完成了濾波這個(gè)環(huán)節(jié)直接輸出高壓直流電（一般在350V以上）給開關(guān)電源電路使用。主動(dòng)式PFC的優(yōu)點(diǎn)很多，比如它改善功率因數(shù)的效果很明顯，可以將電腦電源的功率因數(shù)提高到0.98以上；其次主動(dòng)式PFC還能夠改擴(kuò)寬輸入電壓范圍，從而制成寬電壓輸入的電源。主動(dòng)式PFC的缺點(diǎn)是電路較為復(fù)雜，成本較高。被動(dòng)式PFC電路實(shí)際上只有一個(gè)大的鐵芯電感組成，這個(gè)電感串聯(lián)在整流電路與濾波電容之間，電路很簡潔，利用電感電流不能突變的原理來改善輸入交流電流的波形從而提高功率因數(shù)。它的優(yōu)點(diǎn)是成本低，電路簡單，可靠性高，電磁干擾小；缺點(diǎn)是提升功率因數(shù)的效果有限，一般只能達(dá)到0.8左右?；旧瞎β室驍?shù)可以衡量電力被有效利用的程度。</p><div

PFC電路說白了就是把橋堆整流后的+300V電壓升高到+375V---400V。這也是液晶電視的電源與CRT電視的電源不同之處的一點(diǎn)，不同之處的第二點(diǎn)就是次級電壓比CRT的低，其它的地方與普通的開關(guān)電源原理相同，都一樣。測得大濾波電容330U/450V兩端電壓為+375V---400V，則表明功率因數(shù)校正電路工作正常; 如果測得電容兩端電壓為+300V，說明PFC電路未工作，主查PFC振蕩集成電路。2、檢修液晶電源時(shí); 首PFC振蕩集成電路。先確認(rèn)保險(xiǎn)管狀態(tài)，保險(xiǎn)管完好，通常PFC校正電路中的開關(guān)管等沒有失效。再測量大電解電容對地是否存在短路，有幾十千歐以上充電電阻，表明電源沒有擊穿。3、如果保險(xiǎn)管損壞，一個(gè)要檢查PFC校正電路開關(guān)管，第二個(gè)要檢查副電5 N“、40英寸以下的一般輸出+5V、+12V、+24V三組電壓; 40英寸以上的一般輸出源IC。+5V、+12V、+18V、+24 V四組電壓。其中+5 V為待機(jī)電壓，+12V供數(shù)字板，+18V供伴音，+24 V供背光板。在實(shí)踐維修中，只要各組電壓一樣、功率一樣的電源板都可以代換。被動(dòng)式PFC由多塊硅鋼片外部纏繞銅線而成。深圳PFC電源</p><p style="text-indent:25px">PFC可以在交流轉(zhuǎn)換為直流時(shí)提高電源對市電的利用率。南京主動(dòng)PFC電源廠家</p><p style="text-indent:25px">主動(dòng)式PFC和被動(dòng)式PFC電源共同與不同之處簡單地說，主動(dòng)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(huì)減少電能損耗呢？我們知道，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，電流值就會(huì)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，也是出于降低能耗的考慮。南京主動(dòng)PFC電源廠家</p><p
