Lub hauv paus ntsiab lus ntawm kev hloov hluav taws xob muab hluav taws xob nti
Lub hauv paus ntsiab lus ntawm kev hloov hluav taws xob muab hluav taws xob nti
Switching fais fab mov yog ib hom tshiab ntawm cov khoom siv hluav taws xob, thiab nws txoj haujlwm ua haujlwm yog kom paub txog kev hloov pauv ntawm hluav taws xob thiab lub zog raws li kev qhib thiab kaw ntawm cov khoom siv txuas ntxiv, thiab kom paub txog cov txheej txheem kom tau txais qhov yuav tsum tau muaj qhov ruaj khov voltage lossis tam sim no. los ntawm lub zog input.
Switching fais fab mov nti yog lub hauv paus tseem ceeb ntawm kev hloov hluav taws xob, uas tuaj yeem xaiv cov kev ua haujlwm cuam tshuam raws li cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, thiab paub txog lub zog hloov pauv ntawm cov khoom siv hluav taws xob thiab cov khoom tso tawm los ntawm kev qhib-kaw switching li.
Cov hom kev ua haujlwm tseem ceeb ntawm kev hloov hluav taws xob muab hluav taws xob muaj xws li hom offline thiab qhib-kaw voj hom, uas yog qhov sib txawv hauv kev ua haujlwm, hloov pauv thiab cov lus teb.
1. Offline hom
Offline hom feem ntau yog tsim rau cov ntawv siv hluav taws xob tsawg thiab tsis tshua muaj hluav taws xob, uas yog tus cwj pwm los ntawm cov zis hluav taws xob ruaj khov, tsis tas yuav muaj hluav taws xob sib cais ntawm cov ntawv thov, thiab kev saib xyuas yooj yim.
Off-line hom hloov fais fab mov nti muaj cov yam ntxwv tseem ceeb hauv qab no:
(1) Dav input voltage ntau: Vim qhov xav tau los txhawb tag nrho cov nqi hluav taws xob xws li los ntawm deformed ncov voltage rau ncov voltage, qhov input voltage ntau yog feem ntau dav dua li ntawm cov transformers zoo tib yam.
(2) High-capacitance load: Vim qhov xav tau los txhawb nqa loj-muaj peev xwm loads, lub input capacitance feem ntau loj heev.
(3) Tsis tshua muaj suab nrov: Rau cov ntawv thov uas tsis muaj suab nrov, lub zog hloov hluav taws xob yuav tsum tau kho kom zoo thiab kho.
(4) Kev ua haujlwm siab: txhawm rau kom ntseeg tau tias cov khoom siv hluav taws xob hloov pauv hluav taws xob, kev ua haujlwm siab ua haujlwm yuav tsum tau txais los ntawm kev tsim.
(5) Tus nqi qis: Txhawm rau txhim kho tus nqi sib tw ntawm cov khoom, nws yog ib qho tsim nyog yuav tau txais cov khoom siv pheej yig thiab tsim kom txuag tau cov nqi.
Off-line hom hloov fais fab mov nti yog qhov tseem ceeb ntawm hluav taws xob hluav taws xob uas paub txog kev hloov pauv tsis siv neeg ntawm ob lub xeev ua haujlwm sib txawv. Thaum lub tshuab hluav taws xob qhib, lub nti yog lub luag haujlwm tseem ceeb rau kev pib thiab muab cov khoom siv hluav taws xob, thiab thaum lub hwj chim muab tua, lub nti yog lub luag haujlwm tseem ceeb hauv kev tswj xyuas qhov ruaj khov ntawm cov zis hluav taws xob.
2. Qhib thiab kaw lub voj voog hom
Qhib-kaw lub voj hom yog hom hloov hluav taws xob siab tshaj plaws, thiab nws txoj cai tswj hwm yog ua raws li cov lus qhia tshwj xeeb, uas tuaj yeem ua kom ruaj khov cov zis hluav taws xob thiab kev tawm tswv yim nruj thaum cov zis tam sim no hom thiab hloov pauv.
Qhov qhib-kaw hom switching fais fab mov nti muaj cov yam ntxwv tseem ceeb hauv qab no:
(1) Cov lus teb nrawm dua: Lub voj voog qhib-kaw tuaj yeem kho qhov tso zis hluav taws xob thiab tam sim no sai, ua rau cov lus teb ceev ntawm kev hloov hluav taws xob sai dua. Nws yog tsuas yog siv rau cov nkoj nrog high-ceev cov ntaub ntawv teeb liab hloov thiab thawj cov khoom siv hluav taws xob fragmentation.
(2) Muaj peev xwm tiv taus cov kev hloov pauv: qhib-kaw lub voj voog hom tuaj yeem hloov kho qhov tso zis hluav taws xob thiab tam sim no, thiab hloov mus rau cov kev hloov pauv ntawm cov khoom siv tam sim no thaum tswj qhov zoo ntawm cov zis voltage.
(3) Dav voltage ntau: dav input voltage ntau yog txaus siab, thiab cov zis voltage ntau yam tsis cuam tshuam los ntawm lub hwj chim mov hloov, thiaj li hais tias daim ntawv thov ntau yam ntawm cov khoom yog dav.
(4) txuag hluav taws xob noj: txhawb kev tsim cov khoom siv hluav taws xob ntau dua, yog li txo tus nqi tsim ntawm kev ua haujlwm ntau.
Qhib-kaw-loop switching fais fab mov nti siv AC voltage thiab DC fais fab mov nrog cov lus qhia tshwj xeeb kom paub txog kev tswj fais fab thiab tswj lub zog kom ruaj khov, kom cov khoom siv hluav taws xob tuaj yeem ua haujlwm ruaj khov thiab ntseeg tau raws li kev ua haujlwm ib txwm muaj, yog li ua kom ruaj khov thiab ruaj khov ntawm khoom siv.
