Ib qho kev piav qhia ntxaws txog tsib yam ntawm lub hwj chim tswj chav tsev
1. Kev siv hluav taws xob tsawg thiab kev ua haujlwm siab. Nyob rau hauv lub switching stabilized fais fab mov Circuit Court, lub transistor V yog zoo siab los ntawm lub excitation teeb liab. Nws ua haujlwm sib hloov hauv lub xeev qhib thiab tawm ntawm kev hloov pauv. Kev hloov pauv ceev ceev heev, thiab qhov zaus feem ntau nyob ib puag ncig 50kHz. Hauv qee cov thev naus laus zis, Hauv cov tebchaws, nws tuaj yeem ncav cuag ntau pua lossis ze li 1000kHz. Qhov no ua rau lub zog siv hluav taws xob ntawm kev hloov pauv transistor V me me, thiab kev ua haujlwm ntawm lub zog tuaj yeem txhim kho tau zoo, thiab nws cov txiaj ntsig tuaj yeem ncav cuag 80%.
2. Me me thiab lub teeb yuag. Nws tuaj yeem pom meej meej los ntawm daim duab schematic thaiv ntawm kev hloov pauv tswj fais fab uas tsis muaj hluav taws xob ntau zaus transformer siv. Txij li thaum lub hwj chim dissipation ntawm kev hloov raj V yog txo qis heev, lub dab dej kub loj dua raug tshem tawm. Vim yog ob qho laj thawj no, kev hloov hluav taws xob tswj hluav taws xob yog qhov me me thiab lub teeb hauv qhov hnyav.
3.Wide voltage stabilization ntau. Cov zis hluav taws xob los ntawm kev hloov hluav taws xob tswj hluav taws xob tau hloov kho los ntawm lub luag haujlwm lub voj voog ntawm lub teeb liab excitation. Cov kev hloov pauv hauv cov teeb liab input voltage tuaj yeem raug them los ntawm kev hloov pauv zaus lossis qhov dav dav. Nyob rau hauv no txoj kev, thaum lub hwj chim zaus daim phiaj voltage hloov zoo heev, nws tseem muaj peev xwm xyuas kom meej ib tug ruaj khov tso zis voltage. Yog li ntawd, qhov voltage stabilization ntau yam ntawm switching fais fab mov yog dav heev thiab qhov voltage stabilization nyhuv yog zoo heev. Tsis tas li ntawd, muaj ob txoj hauv kev hloov lub voj voog lub luag haujlwm: pulse width modulation type thiab zaus modulation type. Nyob rau hauv txoj kev no, lub zog hloov hluav taws xob tsis tsuas yog muaj qhov zoo ntawm qhov dav voltage stabilization ntau, tab sis kuj muaj ntau txoj hauv kev kom ua tiav qhov hluav taws xob ruaj khov. Cov neeg tsim qauv tuaj yeem xaiv ntau hom kev hloov khoom siv hluav taws xob raws li qhov xav tau ntawm cov ntawv thov tiag tiag.
4. Lub filtering efficiency yog zoo heev, uas zoo heev txo lub peev xwm thiab ntim ntawm lub lim capacitor. Kev khiav hauj lwm zaus ntawm kev hloov pauv tswj fais fab mov tam sim no pib ua haujlwm ntawm 50kHz, uas yog 1,000 zaus ntawm cov kab hluav taws xob tswj hluav taws xob, uas ua rau kom cov lim dej ua haujlwm zoo tom qab kev kho yuav luag 1,000 zaug . Txawm tias los ntawm kev siv ib nrab-yoj rectification thiab ntxiv capacitor filtering, qhov ua tau zoo yog nce los ntawm 500b zaug. Nyob rau hauv tib lub ripple tso zis voltage, thaum siv ib tug switching tswj fais fab mov, lub peev xwm ntawm lub lim capacitor tsuas yog 1/500-1/1000 ntawm lub lim capacitor nyob rau hauv ib tug linear tswj fais fab mov.
5. Daim ntawv Circuit Court yog hloov tau thiab muaj ntau haiv neeg. Piv txwv li, muaj kev zoo siab rau nws tus kheej thiab nyias muaj nyias hom, dav-modulated thiab zaus-modulated hom, ib leeg-kawg thiab ob-kawg, thiab lwm yam. Cov neeg tsim qauv tuaj yeem ua kom zoo dua qhov zoo ntawm ntau hom circuits thiab tsim cov keyboards uas tuaj yeem ua tau raws li. txawv daim ntawv thov. Fais fab mov.
