Dab tsi digital fais fab mov
Tsis muaj lub ntsiab lus meej thiab sib koom ua ke ntawm cov khoom siv hluav taws xob digital yog dab tsi hauv kev lag luam, thiab cov tuam txhab sib txawv muaj kev txhais lus sib txawv ntawm nws.
Kuv tau txhais cov khoom siv hluav taws xob digital los ntawm qhov kev xav ua haujlwm: cov khoom siv hluav taws xob digital yog cov khoom siv hluav taws xob rau kev tswj hwm digital, uas tuaj yeem muab kev tswj hwm thiab saib xyuas kev ua haujlwm thiab txuas ntxiv mus tswj tag nrho cov circuit.
PechiLou, Tus Thawj Coj Kev Txhim Kho Kev Lag Luam ntawm DC / DC converter supplier PowerOne, ntseeg tias ntxiv rau DpM, lub zog digital yuav tsum suav nrog Digital Power Conversion (DpC) nam. "Lub analog pWM tawm tswv yim voj siv nyob rau hauv ib txwm tsis cais pOL converters tau raug hloov los ntawm cov pWM (DpWM) hauv DpC, tso cai rau cov ntshiab digital tswj ntawm pOL converters." Lou tau taw qhia tias "txawm hais tias nws muaj peev xwm siv ntau yam khoom siv sab nraud rau kev tswj hwm digital ntawm analog converters, nws tsis yog kev lag luam; siv lub tshuab hloov digital tsis tsuas yog ua kom yooj yim rau txoj hauj lwm, tab sis kuj ua rau muaj kev ua haujlwm ntau."
STMicroelectronics (ST) piav qhia los ntawm qhov kev xav ntawm lub hauv paus ntsiab lus, "Lub tswv yim ntawm DpM yog los tswj ntau lub zog hloov pauv hloov pauv thiab cov khoom siv sab nraud los ntawm cov kernel digital thiab embedded kev sib txuas lus interface (feem ntau yog I2C).
Feizhao Semiconductor tau hais txog qhov sib txawv ntawm DpM thiab cov kev daws teeb meem analog fais fab: DpM muab kev tswj hwm kev hloov pauv uas tuaj yeem hloov mus tas li hloov kev xav tau hauv tib daim ntawv thov. DpM siv qhov kev kuaj pom hauv ntej-kawg thiab ua tiav cov txheej txheem sib npaug los muab kev tswj cov zis raws li txhua lub voj voog. Tsis tas li ntawd, DpM tsis xav tau cov khoom siv sab nraud ntxiv, thaum cov kev daws teeb meem ib txwm xav tau kev kho kom zoo nrog cov khoom siv sab nraud
Kev pom ntawm lub hwj chim module chaw tsim tshuaj paus Astec (ib lub koom haum ntawm Emerson) ntawm DpM yog tias nws tau tswj hwm hauv kev tu vaj tse hauv lub zog hluav taws xob thiab pWM tswj lub voj. Yog li ntawd, lub moj khaum ntawm DpM feem ntau muaj ib lossis ntau dua MCUs, qee qhov nyeem thiab sau lub cim xeeb, kev sib txuas lus sib txuas lus, thiab ntau yam thawb-rub lub zog amplifiers thiab sensors.
Qhov tseeb, raws li cov khoom siv hluav taws xob digital, thawj zaug, lub teeb liab tso zis ntawm pWM yog muab los ntawm cov digital tswj nti; Qhov thib ob, kev tawm tswv yim suav ntawm kev tswj lub voj voog yog ua tiav los ntawm chav tsev digital; Qhov thib peb feature yog tib neeg-khoos phis tawj kev sib cuam tshuam, uas pab txhawb kev sib pauv ntaub ntawv thiab ua kom muaj zog tswj tau cov zis thiab kev saib xyuas cov tswv yim; Fourthly, muaj kev sib txuas lus tsheb npav interface uas pab txhawb kev ua haujlwm ntawm pawg saib xyuas thiab kev tswj hwm, kev tswj tsis tu ncua, thiab lwm yam.
