Yuav ua li cas txhawm rau txhim kho kev ua haujlwm ntawm lub programmable DC fais fab mov?
Programmable DC cov khoom siv fais fab yog ib hom khoom siv fais fab uas tuaj yeem tswj cov zis hluav taws xob, tam sim no, thiab lub zog dhau ntawm lub microprocessor. Nws yog dav siv nyob rau hauv teb xws li lub chaw ua hauj lwm, kev siv tshuab, thiab khoom siv khoom siv. Muaj ntau txoj hauv kev thiab cov thev naus laus zis uas tuaj yeem siv los ua kom tau kev ua haujlwm tau zoo ntawm programmabable dc fais fab khoom. Kab lus no yuav muab cov lus qhia ntxaws ntxaws rau qee txoj hauv kev los pab txhim kho kev ua haujlwm ntawm Programmable dc cov khoom siv fais fab.
1, Lub Zog Kev Kho Mob Tshuab
Kev Tsim Kho Kev Kho Mob (PFC) yog ib txoj kev tseem ceeb rau kev txhim kho kev ua haujlwm ntawm lub programmel cov khoom siv. Hauv cov qauv qub qauv puag ncig, muaj kev hloov pauv ntawm qhov tseeb ntawm tam sim no thiab hluav taws xob, uas txhais tau tias lub zog muaj zog yog tsawg. Qhov no yuav ua rau kom wastage ntawm hluav taws xob lub zog, uas ua rau muaj zog qis dua. Los ntawm kev siv fais fab kho tshuab, cov tocology thiab tswj hom ntawm cov Circuit Court tuaj yeem hloov pauv los ua qhov tam sim no thiab voltage hauv theem thiab ze rau sine yoj. Qhov no tuaj yeem ua kom zoo tshaj plaws ntawm kev siv hluav taws xob, txhim kho lub zog hluav taws xob, thiab yog li txhim kho kev ua haujlwm ntawm lub programmelable.
2, txuag hloov fais fab hluav taws xob ntxiv
Xaiv Qhov Tsim Nyog Hloov Powering Zog Khoom Siv Topology Kuj tseem yog qhov tseem ceeb hauv kev txhim kho kev ua tau zoo thaum tsim cov khoom siv DC. Cov neeg siv hluav taws xob ntau zaus hloov cov khoom siv todologebackies tam sim no, ib nrab choj, tag nrho cov choj thiab tag nrho cov xeeb ntxwv ntawm kev ua haujlwm siab. Los ntawm kev tsim lub hwj chim hloov cov khoom siv thiab cov tso zis hloov pauv hloov pauv, yog li kev kho kom haum, yog li kev kho kom haum, ua tau kev ua haujlwm ntawm kev ua haujlwm ntawm lub saws cov khoom siv.
3, muaj txiaj ntsig hwj huam hloov lub cuab yeej
Lub Hwj Chim Hloov Tube tej yam yog ib qho ntawm cov tseem ceeb hauv programmelable dc fais fab khoom siv. Tsoos hluav taws xob hloov khoom xws li cov transistors thiab hloov pauv hloov pauv tau hloov pauv tseem ceeb thiab kev poob qis ntawm cov khoom siv fais fab. Nrog rau kev txhim kho ntawm lub zog saws cov cuab yeej thev naus laus zis, qee cov khoom siv tshiab Mosfets, iGBTS, thiab lwm yam tau siv dav hauv programmelable dc fais fab khoom siv. Lawv muaj cov yam ntxwv ntawm kev ua kom voltage tsis tshua muaj conduction, qis hloov poob, thiab siab hloov ceev. Kev siv cov hwj huam fais fab hloov hluav taws xob tuaj yeem txo tau cov khoom siv hloov chaw thiab kev ua kom tau lub zog ntawm lub zog ntawm lub zog hluav taws xob.
4, txuag tau thev naus laus zis thev naus laus zis
Kev hloov dua siab tshiab tswj tshuab yog ib qho ntawm cov thev naus laus zis tseem ceeb rau kev pab cuam dC fais fab tuag. Cov tsoos PWM (mem tes dav) tswj cov thev naus laus zis muaj qee qhov tsis zoo, xws li anti anti- sib cuam tshuam. Tam sim no, qee qhov kev hloov siab hloov siab hloov thev naus laus zis xws li Realonant hloov dua siab tshiab thiab muaj peev xwm hloov dua siab tshiab thiab ua tau zoo dua. Cov thev naus laus zis tuaj yeem txo cov kev hloov pauv thiab kev ua kom tiav los ntawm kev tswj cov raj thiab tam sim no hloov cov kev ua tau zoo ntawm cov kev ua tiav DC fais fab.
5, Kev Tsim Hluav Taws Xob Tsim Nyog Ua Haujlwm
Kev ua haujlwm siab ua haujlwm DC cov khoom siv hluav taws xob ntau rau cov cua sov thaum ua haujlwm, thiab qhov zoo ntawm tshav kub dissipation ncaj qha cuam tshuam rau kev ua haujlwm ntawm lub zog. Tsim Nyog Cov Kub Kub Fissipation tsim yuav tau zoo txo qhov kub ntawm sab hauv cov khoom siv ntawm lub zog hluav taws xob thiab txhim kho kev ua haujlwm ntawm cov khoom siv. A common heat dissipation design is to use radiators and fans for air cooling and heat dissipation. Tsis tas li ntawd, kev teeb tsa ntawm sab hauv Cheebtsam thiab xaiv ntawm cov ntaub ntawv rwb thaiv tsev hauv cov khoom siv fais fab tseem tuaj yeem cuam tshuam rau cov nyhuv cua sov. Yog li ntawd, thaum tsim qauv DC fais fab tuag, qhov teeb meem ntawm tshav kub dissipation yuav tsum tau ua kom tau cov cua sov kev ntsuas tsim nyog yuav tsum tau txhim kho kev ua haujlwm ntawm lub zog hluav taws xob.
