Lub ntsiab sib txawv ntawm linear fais fab mov thiab switching fais fab mov
Qhov sib txawv ntawm lub zog hloov hluav taws xob thiab cov khoom siv hluav taws xob linear yog qhov lawv ua haujlwm:
Cov cuab yeej hluav taws xob ntawm cov khoom siv hluav taws xob ua haujlwm nyob rau hauv lub xeev linear, uas yog hais tias, lub zog hluav taws xob ib txwm ua haujlwm sai li sai tau thaum siv, yog li nws ua rau nws ua haujlwm qis, feem ntau ntawm 50 [[ feem pua ]] ~ 60 [[ feem pua ]], thiab Nws yuav tsum tau hais tias nws yog ib tug zoo heev linear fais fab mov. Txoj kev ua haujlwm ntawm cov khoom siv hluav taws xob linear ua rau nws tsim nyog yuav tsum muaj cov khoom siv hluav taws xob hloov los ntawm high voltage mus rau qhov tsis tshua muaj hluav taws xob. Feem ntau, nws yog transformer, thiab muaj lwm yam zoo li KX fais fab mov, uas ces rectifies thiab outputs DC voltage. Yog li ntawd, nws lub ntim yog loj, hnyav, tsis tshua muaj efficiency, thiab generates cua sov ntau. Nws kuj muaj nws qhov zoo: me me ripple, kev hloov kho tau zoo, thiab kev cuam tshuam me me sab nraud. Haum rau siv nrog analog circuits, ntau yam amplifiers, thiab lwm yam.
Hloov cov khoom siv hluav taws xob, nws cov khoom siv hluav taws xob ua haujlwm hauv lub xeev hloov pauv (ib qho rau thiab ib qho tawm, ib qho rau thiab ib qho tawm, qhov zaus nrawm heev, qhov zaus ntawm cov vaj huam sib luag tiaj tiaj hloov hluav taws xob yog 100 ~ 200KHz, thiab zaus ntawm module. fais fab mov yog 300 ~ 500KHz). Nyob rau hauv no txoj kev, nws poob yog me me thiab nws efficiency yog siab. Kuj tseem muaj cov kev xav tau rau transformers, uas yuav tsum tau ua los ntawm cov ntaub ntawv nrog siab sib nqus permeability. Nws yog tus cwj mem me me, nws qhov hloov pauv tsuas yog lo lus me me xwb. Kev ua tau zoo yog 80 feem pua rau 90 feem pua. Nws tau hais tias qhov zoo tshaj plaws VICOR module hauv Tebchaws Meskas yog siab li 99 feem pua. Cov khoom siv hluav taws xob hloov hluav taws xob muaj kev ua haujlwm siab thiab me me, tab sis piv nrog cov khoom siv hluav taws xob linear, nws cov ripple thiab voltage thiab tam sim no hloov tus nqi luv nqi.
Cov txheej txheem ua haujlwm ntawm lub hauv paus tseem ceeb ntawm cov khoom siv hluav taws xob tawm yog tias cov khoom siv hluav taws xob nkag tau pib ruaj khov los ntawm qhov pre-stabilized voltage Circuit Court, thiab tom qab ntawd hloov mus rau hauv DC fais fab mov los ntawm kev sib cais thiab kev kho ntawm lub ntsiab ua haujlwm transformer, thiab tom qab ntawd tswj los ntawm kev tswj Circuit Court thiab ib-chip micro-processing maub los. Cov txheej txheem hloov kho tau raug kho kom zoo los ua kom nws tso tawm qhov siab-precision DC voltage qhov chaw.
1. Fais fab transformer thiab rectification: hloov 380V AC rau hauv DC xav tau.
2. Pre-stabilization Circuit Court: Relay Cheebtsam los yog thyristor Cheebtsam yog siv rau pre-kho thiab pib stabilize lub input AC los yog DC voltage, li no yuav txo tau lub hwj chim noj ntawm linear adjustment Cheebtsam thiab txhim kho kev ua hauj lwm efficiency. Thiab xyuas kom meej lub siab precision ntawm cov zis voltage qhov chaw thiab siab stability.
3. Linear adjustment element: Finely adjusted filtered DC voltage to make the input voltage raws li qhov yuav tsum tau muaj tus nqi thiab raug.
4. Filter circuit: Nws tuaj yeem tiv thaiv thiab nqus cov yoj yoj pulsating, cuam tshuam thiab suab nrov ntawm DC fais fab mov mus rau qhov siab tshaj plaws, thiaj li ua kom ntseeg tau tias cov zis hluav taws xob ntawm DC fais fab mov muaj qhov tsis tshua muaj ripple, tsis tshua muaj suab nrov thiab cuam tshuam tsawg.
5. Ib leeg-chip microcomputer tswj qhov system: Ib leeg-chip micro-processing maub los sib piv, txiav txim, xam, txheeb xyuas thiab ua cov txheej txheem ntau yam teeb liab kuaj pom, thiab tom qab ntawd teeb tsa cov lus qhia coj los ua kom tag nrho cov voltage stabilization system ntawm DC stabilized fais fab mov. ua hauj lwm ib txwm thiab ntseeg tau. , kev sib koom tes.
6. Cov khoom siv hluav taws xob sib txuas thiab siv hluav taws xob siv hluav taws xob: muab cov khoom siv hluav taws xob siab tshaj plaws thiab cov khoom siv hluav taws xob xav tau rau kev ua haujlwm hauv hluav taws xob rau DC voltage stabilization system.
7. Voltage sampling and voltage regulation: Nthuav cov zis voltage tus nqi ntawm DC tswj fais fab mov thiab teem thiab kho cov zis voltage tus nqi ntawm DC tswj fais fab mov.
8. Kev sib piv thiab amplification Circuit Court: Tom qab sib piv cov zis voltage tus nqi ntawm DC stabilized fais fab mov nrog qhov voltage ntawm qhov siv qhov chaw kom tau qhov yuam kev voltage teeb liab, ua amplification tawm tswv yim thiab tswj lub linear hloov lub caij los xyuas kom meej stability ntawm cov zis voltage. .
9. Kev kuaj xyuas tam sim no: Tau txais cov txiaj ntsig tam sim no ntawm DC stabilized fais fab mov rau kev txwv tam sim no lossis cov ntaub ntawv tiv thaiv kev tiv thaiv.
10. Tsav Circuit Court: lub hwj chim amplifier Circuit Court teem rau tsav lub executable caij.
