Puas muaj qhov sib txawv loj ntawm lub zog hloov hluav taws xob thiab cov khoom siv hluav taws xob tawm?
Cias muab tso, linear fais fab mov voltage kev cai yuav suav hais tias raws li kev kho tus nqi kuj, sib npaug rau kev kho cov zawv zawg varistor kom hloov voltage, thaum lub switching fais fab mov yog los ntawm kev kho qhov zaus ntawm qhov hloov mus ua qhov voltage hloov. Nyob rau tib lub sijhawm, hloov cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob tawm, piv rau tus nqi ntawm ob qho tib si nrog kev nce hauv cov zis hluav taws xob thiab kev loj hlob, tab sis qhov kev loj hlob ntawm ob qhov sib txawv.
1, linear fais fab mov nqi ntawm ib qho chaw tso zis hluav taws xob, tab sis siab tshaj qhov hloov hluav taws xob.
Yog li ntawd, nrog rau txoj kev loj hlob ntawm lub hwj chim electronics technology thiab innovation, thiaj li hais tias lub switching fais fab mov technology txuas ntxiv mus rau breakthroughs thiab innovation, qhov no yog ib tug nqi teeb meem, tab sis cia lub switching fais fab mov technology mus rau lub low output fais fab tuag, rau lub switching. fais fab mov los muab ntau qhov chaw loj hlob.
2, lub zog hluav taws xob cov khoom siv hluav taws xob thiab cov neeg ua haujlwm, lub neej tau nce zuj zus, thiab cov khoom siv hluav taws xob tsis sib cais los ntawm cov khoom siv hluav taws xob txhim khu kev qha, mus rau 80's tom qab lub khoos phis tawj tau paub txog kev hloov hluav taws xob, mus rau 90's hloov hluav taws xob txuas ntxiv mus rau ntau yam hluav taws xob thiab hluav taws xob teb.
Nyob nruab nrab ntawm kaum xyoo luv luv, hloov cov cuab yeej siv hluav taws xob kom nrawm nrawm ntawm txoj haujlwm tseem ceeb ntawm cov khoom siv hluav taws xob hluav taws xob, puas yog vim qhov me me ntawm kev hloov hluav taws xob?
3, nyob rau hauv qhov tseeb, los ntawm daim duab schematic ntawm lub switching fais fab mov yuav to taub: nws tsis siv lub bulky industrial zaus transformer, nyob rau tib lub sij hawm vim hais tias cov hloov raj ntawm lub dissipation ntawm lub hwj chim yog heev txo, yog li tshem tawm qhov xav tau kev pab. cov dab dej kub loj dua. Qhov no ua rau lub zog hloov hluav taws xob ua me me thiab sib dua. Txawm li cas los xij, qhov txiaj ntsig loj tshaj plaws ntawm kev hloov hluav taws xob yog - kev siv hluav taws xob tsawg thiab kev ua haujlwm siab. Nyob rau hauv lub switching fais fab mov Circuit Court, lub transistor nyob rau hauv lub excitation teeb liab, nws tas li rov hais dua lub 'on' 'raws li ntawm' switching xeev, lub conversion ceev ceev heev, zaus nyob rau hauv 50HZ nkaus xwb, ua lub zog mov efficiency zoo heev.
4, switching fais fab mov voltage regulator ntau yam. Cov zis hluav taws xob los ntawm kev hloov hluav taws xob hloov hluav taws xob yog lub luag haujlwm lub voj voog ntawm lub teeb liab excitation los tswj, lub tswv yim teeb liab teeb liab hloov hluav taws xob tuaj yeem raug them los ntawm kev hloov pauv ntau zaus lossis dav. Nyob rau hauv txoj kev no, nyob rau hauv industrial zaus daim phiaj voltage hloov pauv loj, nws tseem tuaj yeem ua kom muaj qhov tso zis ntau ruaj khov.
5, hloov fais fab mov kev khiav hauj lwm zaus yog pib ua hauj lwm ntawm 50kHz, yog ib tug linear tswj fais fab mov 1000 zaug, uas ua rau lub rectifier filtering efficiency yuav luag 1000 zaug; txawm tias nrog ib nrab-yoj rectification nrog capacitor filtering, qhov ua tau zoo kuj nce 500 zaug. Nyob rau hauv tib lub ripple tso zis voltage, kev siv ntawm switching fais fab mov, lub peev xwm ntawm lub lim capacitor tsuas yog linear tswj fais fab mov lim capacitor 1/500 ~ 1/1000.
