Taw qhia ntawm linear tswj fais fab mov, hloov fais fab mov thiab phased fais fab mov
1. Cov kab hluav taws xob tswj hluav taws xob tuaj yeem ua tau raws li qhov yuav tsum tau muaj ntawm DC voltage thiab fais fab mov zoo (precision, ripple, thiab lwm yam) xav tau los ntawm cov hluav taws xob hluav taws xob, tab sis muaj ob qhov tsis zoo: Ua ntej, tus tswj hwm VT ua haujlwm nyob rau hauv lub xeev linear amplification, nrog kev poob zoo thiab kev siv hluav taws xob tsawg; Qhov thib ob, lub zog zaus transformer T yog xav tau los ua kom tag nrho cov khoom siv hluav taws xob loj thiab hnyav.
2, hloov fais fab mov yog kom kov yeej qhov tsis txaus ntawm cov kab hluav taws xob tswj hluav taws xob, muaj npe vim nws lub zog (lub zog) cov khoom siv hluav taws xob ib txwm ua haujlwm hauv lub xeev hloov. Shaanxi Yike Fais Fab yeej ib txwm yog qhov nyiam hloov hluav taws xob hauv kev ua lag luam kom ntseeg tau cov cuab yeej zoo.
3. Phased fais fab mov yog lub ntsiab lus ntawm thyristor theem tswj fais fab mov. Zoo li lub zog hloov hluav taws xob, cov khoom siv hluav taws xob hluav taws xob hauv cov theem tswj fais fab kuj tseem ua haujlwm nyob rau hauv lub xeev hloov, tab sis lawv cov zaus ua haujlwm yog lub zog zaus (50 Hz) es tsis txhob siv ntau zaus. Nyob rau hauv sib piv, ib tug tseem ceeb kom zoo dua ntawm phased fais fab mov yog nws yooj yim Circuit Court thiab yooj yim tswj. Nws lub ntsiab tsis zoo yog kom muaj lub zog zaus transformer, uas ua rau tag nrho cov khoom siv hluav taws xob loj thiab hnyav. Lub ripple zaus ntawm DC tso zis hluav taws xob ntawm lub sijhawm tswj fais fab no tsuas yog ob peb zaug ntawm lub zog zaus (2 zaug rau ib zaug-theem puv choj tswj thiab 6 zaug rau peb-theem tag nrho-bridge tswj), yog li lub lim loj dua yog xav tau kom ua tau zoo filtering nyhuv. Txawm li cas los xij, ripple zaus ntawm DC tso zis voltage ntawm kev hloov fais fab mov yog siab heev, feem ntau siab tshaj 20 kHz, yog li tsuas yog ib lub lim me me xwb. Vim tias qhov hloov pauv tsawg zaus ntawm cov khoom siv hluav taws xob theem, nws cov lus teb ceev rau kev tswj tau qeeb dua li ntawm kev hloov hluav taws xob.
Kev lig kev cai, kev hloov hluav taws xob yog hais txog DC lub zog hluav taws xob uas lub zog hluav taws xob (lub zog) cov khoom siv hluav taws xob ua haujlwm nyob rau hauv high-frequency switching state, yog li nws tseem hu ua high-frequency switching power supply, thiab phased power supply tsis suav nrog kev hloov hluav taws xob.
