Taw qhia rau Analog zog
Analog fais fab mov: uas yog, lub hwj chim mov ntawm lub transformer, uas yog paub los ntawm cov hlau core thiab lub kauj. Tus naj npawb ntawm lem ntawm lub kauj txiav txim qhov voltage piv ntawm ob kawg. Lub luag haujlwm ntawm cov tub ntxhais hlau yog xa mus rau qhov hloov pauv magnetic teb. 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 neeg ua haujlwm ntawm lawv tus kheej, yog li lawv yuav ua kom sov (poob) vim nws tus kheej inductive tam sim no nyob rau hauv tus txheej txheem ntawm converting voltage, yog li qhov ua tau zoo ntawm lub transformer yog tsawg heev, feem ntau tsis. ntau dua 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, tsuas yog los ntawm kev nce ntawm cov coil tig thiab qhov nce ntawm qhov ntim ntawm cov tub ntxhais hlau, qhov nce ntawm cov lem thiab qhov ntim ntawm cov tub ntxhais hlau yuav nce ntxiv yog li ntawd, lub transformer ntawm lub zog loj amplifier yuav tsum. yuav ua tau loj heev, uas yuav ua rau: Cumbersome thiab calorific.
Taw qhia txog kev hloov hluav taws xob
Hloov fais fab mov: Ua ntej tam sim no nkag mus rau hauv lub transformer, 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 ntau zaus, qhov zaus ntawm magnetic teb hloov pauv mus txog kaum tawm txhiab Hz. Tom qab ntawd, lub kauj yuav raug txo. Tib qhov kev hloov pauv hluav taws xob sib piv tuaj yeem tau txais los ntawm tus lej ntawm qhov hloov pauv 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 kev poob qis heev. Feem ntau, qhov ua tau zoo ntawm cov khoom siv hluav taws xob hloov mus txog 90 feem pua, thiab qhov ntim tuaj yeem ua rau me me, thiab cov khoom siv 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 muaj)
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 lus piav qhia ntawm kev hloov hluav taws xob, yog li txawm tias cov khoom siv hluav taws xob muaj zog, kev hloov hluav taws xob tuaj yeem ua tau zoo heev thiab compactly.
Taw qhia rau digital zog
Hauv cov ntawv thov uas yooj yim siv thiab xav tau qee qhov kev hloov pauv, cov khoom siv hluav taws xob analog muaj txiaj ntsig zoo dua, vim tias qhov cuam tshuam ntawm lawv cov ntawv thov tuaj yeem ua tiav los ntawm kev kho kho vajtse, thaum muaj ntau yam tswj tau, cov lus teb sai dua lub sijhawm, thiab ntau dua. xav tau. Hauv kev siv cov txheej txheem kev ua haujlwm siab uas yuav tsum muaj kev tswj hwm lub zog analog, lub zog digital yog qhov 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 tso cai rau cov neeg siv tau yooj yim hloov cov kev ua hauj lwm tsis thiab optimize lub hwj chim mov system. Nws kuj txo cov naj npawb ntawm cov khoom siv peripheral los ntawm kev tiv thaiv overcurrent thiab tswj lub sijhawm.

Cov khoom siv hluav taws xob digital tuaj yeem tswj tau 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 cov kev xav tau ntawm cov khoom siv hluav taws xob zoo dua li cov khoom siv hluav taws xob tswj los ntawm MCU, nrog rau lub sijhawm teb ceev ceev thiab kev tswj xyuas hluav taws xob zoo dua.
Dab tsi yog cov txiaj ntsig ntawm lub zog digital
Ua ntej tshaj plaws, nws yog programmable. Tag nrho cov haujlwm xws li kev sib txuas lus, nrhiav pom, telemetry, thiab lwm yam tuaj yeem ua tiav los ntawm software programming. Tsis tas li ntawd, cov khoom siv hluav taws xob digital muaj kev ua haujlwm siab thiab kev ntseeg tau, thiab hloov tau yooj yim.
Kev cuam tshuam: Nruab nrab ntawm cov digital thiab analog nyob rau hauv ib lub microcomputer, vim hais tias cov teeb liab digital yog lub teeb liab mem tes nrog lub dav spectrum, kev cuam tshuam ntawm qhov digital thiab qhov analog feem ntau yog muaj zog; Tsis yog tsuas yog cov khoom siv hluav taws xob digital thiab cov khoom siv hluav taws xob analog sib cais, Lim kev sib txuas, hauv qee lub sijhawm xav tau siab, xws li thaum lub AD converter hauv qee lub tshuab microcomputer ua AD hloov dua siab tshiab, feem ntau cov digital feem ntau muab tso rau hauv lub xeev dormant. , thiab feem ntau ntawm cov logic digital nres ua haujlwm los tiv thaiv lawv los ntawm kev tsim cov analog. cuam tshuam. Yog tias qhov cuam tshuam loj heev, koj tuaj yeem siv ob lub hwj chim sib cais, feem ntau siv inductors thiab capacitors cais lawv. Koj tseem tuaj yeem txuas cov khoom siv hluav taws xob ntawm cov khoom siv digital thiab analog ntawm tag nrho pawg thawj coj ua ke, thiab siv cov kev sib cais los txuas ncaj qha mus rau cov pob qij txha ntawm lub hwj chim lim capacitors. Yog tias qhov kev xav tau los tiv thaiv kev cuam tshuam tsis siab, koj tuaj yeem txuas lawv ua ke.
