Yuav ua li cas peb xaiv lub hwj chim module nyob rau hauv lub hwj chim mov tsim? Lub hauv paus ntawm kev xaiv yog tias peb yuav tsum nkag siab txhua yam ntawm cov khoom siv hluav taws xob thiab qhov sib txawv ntawm lawv, yog li peb tuaj yeem xaiv lub zog module kom raug.
Taw qhia rau Analog zog
Analog fais fab mov: uas yog, transformer fais fab mov, uas 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. (kuv lub teb chaws) Lub ntsiab coil tsim cov hlau nplaum hloov pauv ntawm qhov zaus ntawm 50HZ. Qhov no hloov magnetic teb yog kis mus rau lub thib ob kauj los ntawm cov hlau core, thiab ib tug induced voltage yog generated nyob rau hauv lub thib ob kauj, yog li ntawd lub transformer realizes lub voltage transformation.
Qhov tsis zoo ntawm cov khoom siv hluav taws xob analog: lub kauj thiab cov tub ntxhais hlau yog cov khoom siv hluav taws xob, yog li lawv yuav tsim kom muaj cua sov (poob) vim nws tus kheej induction tam sim no thaum lub sijhawm hloov hluav taws xob, yog li qhov ua tau zoo ntawm transformer yog tsawg heev, feem ntau tsis ntau tshaj 35. feem pua.
Daim ntawv thov ntawm transformers nyob rau hauv cov khoom siv lub hwj chim amplifiers: high-power hwj chim amplifiers yuav tsum tau transformers muab ntau zog tso zis. Tom qab ntawd, nws tsuas tuaj yeem pom tau los ntawm kev ua kom cov coil tig thiab qhov nce ntawm cov tub ntxhais hlau ntim, thiab qhov nce ntawm cov lem thiab hlau core ntim yuav ua rau nws poob, yog li lub transformer ntawm high-power fais fab amplifier yuav tsum yog. ua loj heev, uas yuav ua rau: loj heev, high kub tiam.
Taw qhia txog kev hloov hluav taws xob
Hloov fais fab mov: Ua ntej qhov tam sim no nkag mus rau hauv lub tshuab hloov pauv, los ntawm kev hloov pauv ntawm lub transistor, qhov zaus tam sim no ntawm peb li niaj zaus 50HZ tau nce mus rau kaum tawm txhiab Hz. Nyob rau hauv xws li ib tug high zaus, qhov zaus ntawm lub magnetic teb hloov pauv kuj nce mus txog kaum tawm txhiab Hz, yog li cov coil Tus naj npawb ntawm cov lem thiab qhov ntim ntawm cov tub ntxhais hlau tau txais tib qhov kev hloov pauv voltage. Vim qhov txo qis ntawm cov coil tig thiab qhov ntim ntawm cov tub ntxhais hlau, qhov kev poob qis heev. Feem ntau, qhov ua tau zoo ntawm kev hloov hluav taws xob hloov mus txog 90 feem pua, thiab lub ntim tuaj yeem ua rau me me, thiab cov khoom tso tawm tau ruaj khov, yog li cov khoom siv hluav taws xob hloov pauv muaj qhov zoo uas nyuaj rau kev ua tiav nrog cov khoom siv hluav taws xob analog.
(Switching fais fab mov kuj muaj nws tus kheej shortcomings, xws li tso zis voltage ripple thiab hloov suab nrov, linear fais fab mov tsis)
Cov khoom siv suab-Daim ntawv thov ntawm kev hloov hluav taws xob hauv lub tshuab hluav taws xob: Qhov zoo ntawm kev hloov hluav taws xob tau pom nyob rau hauv cov txheej txheem kev piav qhia ntawm kev hloov hluav taws xob, yog li txawm tias nws yog lub zog hluav taws xob loj, kev hloov hluav taws xob tuaj yeem ua tau zoo heev. thiab me me.
Taw qhia rau Digital Power
Hauv cov ntawv thov uas yooj yim siv thiab xav tau qee qhov kev hloov pauv, cov khoom siv hluav taws xob analog muaj qhov zoo dua, vim tias qhov cuam tshuam ntawm lawv daim ntawv thov tuaj yeem pom tau los ntawm kev kho kho vajtse, thiab hauv cov ntawv thov uas muaj ntau yam tswj tau, nrawm dua lub sijhawm teb ceev, thiab ntau nyob rau hauv complex high-kev ua tau zoo system daim ntaub ntawv uas yuav tsum tau ib tug analog system hwj chim tswj, digital hwj chim yog zoo dua. Nyob rau hauv tas li ntawd, nyob rau hauv complex multi-system kev lag luam, piv nrog analog fais fab mov, cov khoom siv hluav taws xob digital paub txog ntau yam kev siv los ntawm software programming. Nws scalability thiab reusability pab kom cov neeg siv tau yooj yim hloov cov kev ua hauj lwm tsis thiab optimize fais fab mov system. Nws kuj txo cov naj npawb ntawm cov khoom siv peripheral los ntawm kev tiv thaiv overcurrent thiab tswj lub sijhawm.
