Lub linear programmable fais fab mov ua haujlwm li cas? Tus qauv tsim yog dab tsi?
Cov khoom siv hluav taws xob programmable tau siv dav hauv kev sim thiab ntsuas ntau yam khoom siv hluav taws xob thiab tau nthuav dav mus rau lwm qhov kev lag luam thiab. Programmable fais fab mov yog siv nyob rau hauv cov tsoos electroplating kev lag luam, uas yuav zoo heev txhim kho qhov zoo thiab automation ntawm electroplating khoom. Txo kev siv nyiaj. Tsis tas li ntawd, vim qhov ua tau zoo ntawm cov khoom siv hluav taws xob programmable, kev siv hluav taws xob hauv ntau cov kev lag luam ib txwm tuaj yeem txo qis heev.
Tom ntej no, peb yuav piav qhia yuav ua li cas linear programmable fais fab mov ua haujlwm.
Cov qauv tsim qauv yooj yim ntawm cov khoom siv hluav taws xob suav nrog rectifier thiab cov khoom siv thauj khoom thiab tswj cov khoom sib txuas hauv cov koob.
Simplified circuit diagram ntawm ib series rectified fais fab mov. Nws muaj ib tug pre-regulator (raws li ib tug Circuit Court breaker) rau theem tswj thiab ib tug sib txawv impedance series caij. Ib theem-tswj pre-regulator minimizes lub hwj chim dissipation los ntawm kev tuav ib tug ruaj khov uas tsis muaj dropout nyob rau hauv series. Lub tswv yim tswj Circuit Court tsis tu ncua saib xyuas cov khoom siv hluav taws xob thiab kho cov kev cuam tshuam series kom stabilize cov zis hluav taws xob tas li.
Cov khoom siv sib txawv tsis sib xws hauv cov khoom siv hluav taws xob tiag tiag muaj ib lossis ntau lub zog transistors ua haujlwm hauv hom kab, yog li lub zog siv hluav taws xob siv hom rectifier no feem ntau hu ua linear fais fab mov. Linear fais fab mov muaj ntau yam zoo. Nrog nws cov kev ruaj ntseg siab thiab tsis tshua muaj suab nrov, nws yog qhov yooj yim tshaj plaws thiab zoo tshaj plaws kev daws teeb meem ntawm R & D lub rooj ntev zaum.
Lub zog hluav taws xob yog ob lub zog hluav taws xob uas tuaj yeem muaj qhov hluav taws xob ntau dua thaum qhov tam sim no qis dua thiab muaj zog dua tam sim no thaum qhov hluav taws xob qis dua. Nrog rau ib qho kev siv hluav taws xob ib leeg, lub zog tso zis yog nyob ntawm nws qhov siab tshaj plaws tsuas yog thaum ob qho tib si qhov hluav taws xob thiab cov zis tam sim no nyob ntawm lawv qhov siab tshaj plaws. Ib qho hluav taws xob tawm hluav taws xob nrog ob ntu tuaj yeem muab lub zog tso zis ntau tshaj qhov uas ob ntu muaj qhov siab tshaj plaws thiab cov zis tam sim no. Thaum siv cov khoom siv hluav taws xob dual, muaj kais hauv nruab nrab ntawm cov kab txuas txuas ntxiv los ntawm lub ntsiab transformer, nyob ze ntawm lub davhlau ya nyob twg ntsaws. Ib qho kev hloov nyob rau hauv pem hauv ntej ntawm lub pre-regulator tuaj yeem toggled ncaj qha ntawm ob qhov tso zis, thiab cov zis tom qab tau txiav txim siab lawm. High voltage, tsawg tam sim no hom los yog tsawg tam sim no-high voltage hom. Cov txheej txheem no muaj txiaj ntsig zoo hauv kev txo qis kev siv hluav taws xob ntawm cov khoom siv serial.
Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, cov khoom siv hluav taws xob linear muaj qhov zoo tshaj plaws thiab cov yam ntxwv ntawm kev thauj khoom thiab tuaj yeem teb sai rau cov kab sib chaws thiab kev hloov pauv. Yog li, txoj kab kev tswj hwm, kev tswj hwm kev thauj khoom thiab lub sijhawm hloov pauv hloov pauv tau zoo dua li cov khoom siv hluav taws xob hloov pauv feem ntau. Cov khoom siv hluav taws xob tawm muaj ntau yam zoo xws li: tsis tshua muaj ripple thiab suab nrov, ua siab ntev rau qhov kub thiab txias hloov, thiab kev ntseeg siab.
Nyob rau hauv lub programmable linear fais fab mov, lub digital tswj Circuit Court tswj cov zis tswj theem ntawm DAC kom ncaj qha tswj cov programmed voltage tus nqi ntawm lub hwj chim mov. Cov zis ntawm lub hwj chim mov yuav ib txhij xa ib qhov hluav taws xob mus rau lub tswj Circuit Court los qhia tias nws muaj qhov xav tau qhov hluav taws xob tso zis voltage. Tom qab lub Circuit Court tswj tau txais cov ntaub ntawv voltage los ntawm qhov tso zis davhlau ya nyob twg, nws xa cov ntaub ntawv mus rau cov zaub. Ib yam zoo sib xws, lub Circuit Court tswj kuj ceeb toom rau lwm yam khoom siv ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob los ntawm lub PC interface xws li GPIB, RS-232, USB lossis LAN. Cov PC interfaces no ncaj qha hauv av thiab opto-kab tawm yog siv los ntawm kev tswj Circuitry thiab cov khoom siv hluav taws xob.
Linear DC fais fab mov yog qhov nyuaj heev los tsim thiab ua tau zoo heev. Txawm li cas los xij, qhov teeb meem tseem ceeb yog qhov ua haujlwm qis. Ntawm qhov tso zis tag nrho, kev ua haujlwm feem ntau tsis ncav cuag 60 feem pua. Yog tias qhov tso zis hluav taws xob tau teeb tsa qis dua, qhov ua tau zoo yuav raug txo ntxiv. Raws li lub zog nce, ntim thiab qhov hnyav kuj nce proportionally. Yog li ntawd, cov khoom siv hluav taws xob hloov pauv tau siv ntau dua hauv cov khoom siv hluav taws xob ua haujlwm siab.
