Taw qhia txog Kev Hloov Cov Khoom Siv Hluav Taws Xob thiab Phase Control Fais Fab
1. Linear tswj fais fab mov tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm qhov siab thiab qis DC voltage xav tau los ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob zoo (qhov tseeb, ripple, thiab lwm yam), tab sis muaj ob qhov teeb meem loj: ua ntej, kho VT transistor ua haujlwm hauv ib qho linear amplification xeev, ua rau poob siab thiab tsis muaj zog efficiency; Qhov thib ob yog siv lub zog zaus transformer T los ua kom tag nrho cov khoom siv hluav taws xob loj thiab hnyav.
2. Cov khoom siv hluav taws xob hloov hluav taws xob yog tsim los daws qhov teeb meem ntawm cov khoom siv hluav taws xob linear tswj, muaj npe tom qab lawv lub zog (lub zog) cov khoom siv hluav taws xob uas ib txwm ua haujlwm hauv lub xeev hloov.
3. Phase tswj fais fab mov yog cov ntawv luv ntawm thyristor theem tswj fais fab mov. Zoo ib yam li hloov cov khoom siv hluav taws xob, cov khoom siv hluav taws xob hluav taws xob hauv theem tswj cov khoom siv hluav taws xob kuj tseem ua haujlwm hauv lub xeev hloov pauv, tab sis lawv qhov kev khiav hauj lwm zaus yog lub zog zaus (50Hz), tsis muaj zaus. Nyob rau hauv sib piv, ib tug tseem ceeb kom zoo dua ntawm theem tswj fais fab mov yog nws yooj yim Circuit Court thiab yooj yim tswj. Nws lub ntsiab drawback yog qhov yuav tsum tau rau ib lub hwj chim zaus transformer, uas ua rau tag nrho cov fais fab mov loj loj thiab hnyav. Tsis tas li ntawd, ripple zaus ntawm DC tso zis voltage ntawm theem tswj fais fab mov tsuas yog ob peb zaug ntawm lub zog zaus (2 zaug rau ib theem tag nrho tswj choj thiab 6 zaug rau peb-theem puv choj tswj), thiab Cov lim loj dua yuav tsum muaj cov lim dej zoo. DC tso zis voltage ripple zaus ntawm kev hloov fais fab mov yog siab heev, feem ntau siab tshaj 20kHz, yog li tsuas yog xav tau lub lim me me xwb. Vim tias qhov hloov pauv tsawg zaus ntawm theem tswj fais fab mov, nws cov lus teb ceev rau kev tswj kuj tseem qeeb dua li ntawm cov khoom siv hluav taws xob hloov.
Raws li cov lus pom zoo, lub zog hloov hluav taws xob tshwj xeeb yog hais txog lub zog hluav taws xob DC uas lub zog (lub zog) cov khoom siv hluav taws xob ua haujlwm hauv lub xeev hloov pauv siab, yog li nws tseem hu ua lub zog hloov hluav taws xob ntau, thaum lub sijhawm tswj fais fab. cov khoom siv tsis suav nrog hauv cov khoom siv hluav taws xob hloov pauv.
