High PFC tswj kev hloov fais fab mov

PFC yog lub ntsiab lus ntawm kev kho lub zog, uas yog siv los ua tus cwj pwm ntawm kev siv hluav taws xob los ntawm cov khoom siv hluav taws xob.Lub zog ntau dua, qhov kev siv hluav taws xob ntau dua.

Muaj ob hom PFC: passive PFC thiab nquag PFC.Passive PFC feem ntau siv cov kev them nyiaj inductance los txo cov theem sib txawv ntawm qhov tseem ceeb tam sim no thiab qhov hluav taws xob ntawm AC cov tswv yim los txhim kho lub zog, tab sis lub zog ntawm passive PFC tsis siab heev thiab tuaj yeem ncav cuag 0.7 ~ 0.8;Active PFC yog tsim los ntawm inductance, capacitance thiab cov khoom siv hluav taws xob, nws tuaj yeem ncav cuag 0.99.Nws yog qhov me me thiab tuaj yeem ua tiav lub zog siab, tab sis tus nqi siab dua li ntawm passive PFC.

PFC feem ntau yog siv los ua lub zog siv hluav taws xob hauv PC, thiab PFC muaj cov yam ntxwv nram qab no tsawg kawg:

1) Input voltage tuaj yeem yog 90V txog 270V;

2) Cov kab hluav taws xob muaj zog yog siab dua 0.98, thiab muaj qhov zoo ntawm kev poob qis thiab kev ntseeg siab;

3) PFC ntawm IC kuj tseem siv tau los ua cov khoom siv hluav taws xob, yog li qhov kev hloov pauv hloov pauv feem ntau tsis tas yuav tsum tau siv hauv kev siv PFC Circuit Court;

4) Cov zis tsis hloov pauv nrog cov khoom siv hluav taws xob, yog li cov zis hluav taws xob ruaj khov tuaj yeem tau txais;

5) Cov zis DC voltage ripple ntawm nquag PFC yog me me thiab nthuav tawm sine yoj ntawm 100Hz / 120Hz (ob zaug lub zog zaus).Yog li ntawd, lub zog siv hluav taws xob siv PFC tsis tas yuav siv lub peev xwm loj lim capacitor.

Active PFC yog tsim los ntawm inductance, capacitance thiab cov khoom siv hluav taws xob.Nws muaj qhov ntim me me.Nws kho qhov tam sim no waveform los ntawm IC tshwj xeeb los them cov theem sib txawv ntawm tam sim no thiab voltage.Active PFC tuaj yeem ua tiav lub zog muaj zog - feem ntau ntau dua 98%, tab sis tus nqi kuj tseem siab.Tsis tas li ntawd, lub active PFC kuj tseem siv tau los ua cov khoom siv hluav taws xob.Yog li ntawd, nyob rau hauv kev siv lub active PFC Circuit Court, lub standby transformer feem ntau tsis tas yuav tsum tau, thiab lub ripple ntawm cov zis DC voltage ntawm lub active PFC yog heev me me.Lub hwj chim mov no tsis tas yuav siv lub peev xwm loj lim capacitor.

Peb nyuam qhuav pib 2000W thiab 3000W hloov cov khoom siv hluav taws xob nrog PFC.Tus nqi yog qhov zoo heev.Nws yog ntau pheej yig dua li tib lub hwj huam mov ntawm lub khw, thiab kev ua tau zoo heev.Yog tias koj txaus siab rau nws, thov hu rau peb.Ua tsaug!
