style="text-indent:25px">PFC電路原理?PFC就是“功率因數(shù)”的意思，主要用來表征電子產(chǎn)品對電能的利用效率。功率因數(shù)越高，說明電能的利用效率越高。?PFC有兩種，一種是無源PFC（也稱被動式PFC），一種是有源PFC（也稱主動式PFC）。無源PFC一般采用電感補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，只能達到0.7~0.8；有源PFC由電感電容及電子元器件組成，體積小，可以達到很高的功率因數(shù)，但成本要高出無源PFC一些。?有源PFC電路中往往采用高集成度的IC，采用有源PFC電路的PC電源，至少具有以下特點：?（1）?輸入電壓可以從90V到270V；（?2）?高于0.99的線路功率因數(shù)，并具有低損耗和高可靠等優(yōu)點；?（3）?IC的PFC還可用作輔助電源，因此在使用有源PFC電路中，往往不需要待機變壓器；?（4）?輸出不隨輸入電壓波動變化，因此可獲得高度穩(wěn)定的輸出電壓；?5）?有源PFC輸出DC電壓紋波很小，且呈100Hz/120Hz（工頻2倍）的正弦波，因此采用有源PFC的電源不需要采用很大容量的濾波電容。主動PFC電源哪家好主動式PFC電路的升壓能力，能容許較低的輸入電壓。</p><div

Corrector，意思是功率因數(shù)校正器，它可以在交流轉(zhuǎn)換為直流時提高電源對市電的利用率，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。主動式PFC電源能減少電源對市電電網(wǎng)的干擾，尤其是避免它在突然啟動時對其他電器的影響。PFC分為主動式（有源）和被動式（無源）兩種，它們是衡量電源檔次高低的一個重要因素。一般來說，功率在250W～300W的電源多采用被動式PFC，而主動式PFC則常用于400W及以上的中高級電源。就性能而言，主動式PFC擁有更高的功率因數(shù)（高達99%），配合好的電路設(shè)計，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；而主動式PFC則由電感線圈配合IC控制芯片組成。</p><p

12V或+24V輸出端帶有一定功率的負載，主開關(guān)電源才進行正常的工作狀態(tài)。所以在+24V輸出端上你可以接一只電動自行車的36 V燈泡作假負載（或在+ 12V輸出端接一只摩托車燈泡作假負載）即可。5、液晶電源通電后，副電源先工作，輸出+5V電壓給數(shù)字板上的CPU，此時整機處于待機狀態(tài)。當(dāng)按”待機“鍵后，CPU輸出開機電平，PFC 電路先工作，將+300V脈動直流電壓轉(zhuǎn)換成正常的直流電壓（+380V）后，這時主開關(guān)電源的脈寬振蕩器才開始工作; 接著主開關(guān)變壓器次級輸出+ 12V、+24V電壓，整機進入正常工作狀態(tài)。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。</p><div style="width:100%;text-align:

style="text-indent:25px">開關(guān)電源pfc常見故障：無直流電壓輸出或電壓輸出不穩(wěn)定：如果保險絲是完好的，在有負載情況下，各級直流電壓無輸出。這種情況主要是以下原因造成的：電源中出現(xiàn)開路、短路現(xiàn)象，過壓、過流保護電路出現(xiàn)故障，輔助電源故障，振蕩電路沒有工作，電源負載過重，高頻整流濾波電路中整流二極管被擊穿，濾波電容漏電等。在用萬用表測量次級元件，排除了高頻整流二極管擊穿、負載短路的情況后，如果這時輸出為零，則可以肯定是電源的控制電路出了故障。若有部分電壓輸出說明前級電路工作正常，故障出在高頻整流濾波電路中。高頻濾波電路主要由整流二極管及低壓濾波電容組成直流電壓輸出，其中整流二極管擊穿會使該電路無電壓輸出，濾波電容漏電會造成輸出電壓不穩(wěn)等故障。用萬用表靜態(tài)測量對應(yīng)元件即可檢查出其損壞的元件。主動式PFC一般由功率MOFET開關(guān)管、PFC二極管、電感、等六個電子元器件組成。青島主動PFC電源批發(fā)哪家好</p><p
