Lub zog hloov hluav taws xob yog qhov zoo.
Switching fais fab mov muaj peb qhov zoo, raws li hauv qab no:
1) Kev siv hluav taws xob tsawg thiab kev ua haujlwm siab.Nyob rau hauv lub switching fais fab mov Circuit Court, nyob rau hauv lub excitation ntawm lub excitation teeb liab, lub transistor V ua hauj lwm sib hloov nyob rau hauv lub on-off thiab on-off switching xeev.Kev hloov pauv ceev ceev heev, thiab qhov zaus feem ntau yog li 50kHz.Hauv qee lub tebchaws nrog cov thev naus laus zis siab, ntau pua lossis ze li 1000kHz tuaj yeem ua tiav.Qhov no ua rau lub zog siv ntawm kev hloov pauv transistor V me me heev, thiab qhov ua tau zoo ntawm cov khoom siv hluav taws xob tuaj yeem txhim kho tau zoo, uas tuaj yeem ncav cuag 80%.
2) Me me thiab lub teeb yuag.Los ntawm daim duab schematic ntawm kev hloov hluav taws xob, nws tuaj yeem pom meej tias tsis muaj lub zog loj zaus transformer siv ntawm no.Txij li thaum lub zog dissipated ntawm qhov kho lub raj V tau txo qis heev, lub dab dej kub loj dua kuj raug tshem tawm.Vim yog ob qho laj thawj no, lub zog hloov hluav taws xob yog qhov me me thiab lub teeb hauv qhov hnyav.
3) Ntau yam ntawm voltage stabilization.Cov zis hluav taws xob ntawm tus qhev hloov hluav taws xob yog tswj hwm los ntawm lub luag haujlwm lub voj voog ntawm lub teeb liab excitation, thiab kev hloov pauv ntawm cov teeb liab input voltage tuaj yeem them nyiaj los ntawm kev hloov pauv ntau zaus lossis qhov dav dav.Nyob rau hauv txoj kev no, thaum lub hwj chim zaus daim phiaj voltage hloov pauv zoo heev, nws tseem tuaj yeem ua kom muaj qhov tso zis ntau dua.Yog li ntawd, qhov voltage stabilizing ntau yam ntawm switching fais fab mov yog dav heev thiab qhov voltage stabilizing nyhuv yog zoo heev.Tsis tas li ntawd, muaj ob txoj hauv kev los hloov lub voj voog lub luag haujlwm: pulse width modulation thiab zaus hloov kho.Lub zog hloov hluav taws xob tsis yog tsuas yog muaj qhov zoo ntawm qhov dav voltage stabilization ntau yam, tab sis kuj muaj ntau txoj hauv kev kom paub qhov voltage stabilization.Cov neeg tsim qauv tuaj yeem hloov pauv ntau hom kev hloov pauv hluav taws xob raws li qhov xav tau ntawm kev siv tswv yim.
Kuv vam tias nws yuav pab tau koj.
