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(guò)程的電能損耗，也沒(méi)有節(jié)約電能的功能。主動(dòng)式PFC電源：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(shuō)，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及以上的中高類型的電源。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(guò)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。主動(dòng)式PFC輸出直流電壓的紋波很小，這種電源不必采用很大容量的濾波電容。天津主動(dòng)式PFC電源價(jià)格</p><p

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(lái)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。主動(dòng)式PFC則由電感電容及電子元器件組成，體積小、通過(guò)**IC去調(diào)整電流的波形，對(duì)電流電壓間的相位差進(jìn)行補(bǔ)償。主動(dòng)式PFC可以達(dá)到較高的功率因數(shù)──通常可達(dá)98%以上，但成本也相對(duì)較高。此外，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，而且主動(dòng)式PFC輸出直流電壓的紋波很小，這種電源不必采用很大容量的濾波電容。深圳被動(dòng)式PFC電源哪家好</p></p><br
