Qhov sib txawv ntawm switching fais fab mov thiab analog fais fab mov
Analog fais fab mov: transformer fais fab mov yog paub los ntawm hlau core thiab coil. Tus naj npawb ntawm lem ntawm lub kauj txiav txim qhov voltage piv ntawm ob qho kawg. Lub luag haujlwm ntawm cov tub ntxhais hlau yog xa mus rau qhov hloov pauv magnetic teb. (Tuam Tshoj) Lub ntsiab coil generates ib tug hloov magnetic teb ntawm ib zaus ntawm 50HZ, uas yog kis mus rau lub auxiliary coil los ntawm cov hlau core, thiab ib tug induced voltage yog generated nyob rau hauv lub auxiliary coil, yog li ntawd lub transformer realizes voltage conversion.
Qhov tsis zoo ntawm cov khoom siv hluav taws xob analog: lub kauj thiab cov tub ntxhais hlau yog cov neeg ua haujlwm ntawm lawv tus kheej, yog li lawv yuav tsim kom muaj cua sov (poob) vim nws tus kheej induced tam sim no nyob rau hauv tus txheej txheem ntawm kev hloov hluav taws xob, yog li qhov ua tau zoo ntawm transformer yog tsawg heev, feem ntau tsis tshaj 35%. .
Qhov sib txawv ntawm switching fais fab mov thiab analog fais fab mov
Daim ntawv thov ntawm transformer nyob rau hauv lub suab khoom siv lub hwj chim amplifier: High-power hwj chim amplifier xav tau transformer muab ntau lub zog tso zis, yog li nws tsuas muaj peev xwm paub tau los ntawm kev nce tus naj npawb ntawm cov kauj thiab qhov ntim ntawm cov tub ntxhais hlau, uas yuav ua rau nws poob ntau dua. Yog li ntawd, lub transformer ntawm high-power hwj chim amplifier yuav tsum tau ua loj heev, uas yuav ua rau: hnyav thiab loj kub.
Hloov fais fab mov: Ua ntej tam sim no nkag mus rau hauv lub tshuab hloov pauv, qhov zaus tam sim no ntawm 50HZ tau nce mus rau kaum tawm txhiab HZ los ntawm kev hloov pauv ntawm lub transistor. Nyob rau hauv xws li ib tug high zaus, qhov zaus ntawm magnetic teb hloov kuj mus txog kaum tawm txhiab HZ. Tom qab ntawd, tib qhov kev hloov pauv hluav taws xob tuaj yeem tau txais los ntawm kev txo cov coil tig thiab qhov ntim ntawm cov tub ntxhais hlau. Vim qhov txo qis ntawm cov coil tig thiab qhov ntim ntawm cov tub ntxhais hlau, qhov poob tau txo qis heev. Feem ntau, qhov ua tau zoo ntawm kev hloov hluav taws xob hloov mus txog 90%, tab sis qhov ntim tuaj yeem ua tau me me thiab cov zis ruaj khov.
(Switching fais fab mov kuj muaj nws tus kheej shortcomings, xws li ripple nyob rau hauv cov zis voltage thiab hloov suab nrov, uas linear fais fab mov tsis muaj)
Digital fais fab mov
Cov khoom siv hluav taws xob analog muaj qhov zoo hauv cov ntawv thov uas yooj yim thiab siv tau yooj yim thiab yuav tsum muaj qee qhov kev hloov pauv, vim tias qhov cuam tshuam ntawm lawv daim ntawv thov tuaj yeem ua tiav los ntawm kev kho vajtse ruaj khov, thaum cov khoom siv hluav taws xob digital muaj qhov zoo hauv cov txheej txheem kev ua haujlwm siab nrog ntau yam tswj tau. yam, cov lus teb sai dua lub sijhawm thiab xav tau kev tswj hwm lub zog ntawm ntau lub tshuab analog. Tsis tas li ntawd, nyob rau hauv ntau txoj kev lag luam, piv nrog cov khoom siv hluav taws xob analog, cov khoom siv hluav taws xob digital tau siv ntau yam los ntawm software programming, thiab nws qhov kev nthuav dav thiab rov siv tau ua rau cov neeg siv tau yooj yim hloov cov kev ua haujlwm tsis zoo thiab txhim kho lub zog siv hluav taws xob. Los ntawm kev tiv thaiv overcurrent thiab tswj lub sijhawm tiag tiag, nws tuaj yeem txo tus naj npawb ntawm cov khoom siv peripheral.
Qhov sib txawv ntawm switching fais fab mov thiab analog fais fab mov
Nyob rau hauv complex multi-system lag luam, piv nrog analog fais fab mov, cov khoom siv hluav taws xob digital yog siv rau ntau yam los ntawm software programming. Nws expansibility thiab reusability ua rau nws yooj yim rau cov neeg siv hloov pauv tsis ua hauj lwm thiab optimize fais fab mov system. Los ntawm kev tiv thaiv overcurrent thiab tswj lub sijhawm tiag tiag, nws tuaj yeem txo tus naj npawb ntawm cov khoom siv peripheral.
Cov khoom siv hluav taws xob digital yog tswj los ntawm DSP thiab MCU. Hais txog hais lus, lub hwj chim tswj los ntawm DSP txais cov kev lim dej digital, uas tuaj yeem ua tau raws li qhov xav tau ntawm lub zog nyuaj, muaj cov lus teb sai dua lub sijhawm thiab zoo dua lub zog hluav taws xob muaj zog dua li lub zog tswj los ntawm MCU.
Dab tsi yog qhov zoo ntawm cov khoom siv hluav taws xob digital? Ua ntej tshaj plaws, nws yog programmable. Piv txwv li, txhua txoj haujlwm xws li kev sib txuas lus, kev tshawb nrhiav thiab telemetry tuaj yeem ua tiav los ntawm software programming. Tsis tas li ntawd, cov khoom siv hluav taws xob digital muaj kev ua haujlwm siab, muaj kev ntseeg siab thiab hloov tau yooj yim.
