Lub hauv paus rau phau ntawv
Muaj cov tshuab ua tshuab tsis muaj kev hloov pauv kom txo qis thiab downtime. Qhov kev rau siab no, lub npe hu ua Kev Lag Luam 4.0, yuav embers ntau dua li hmi ntawm hmi los ntawm kev sib txuas lus, actuatators, thiab sensors.
Qhov kev tawm tsam no piv txwv txog kev sib tw networking, qhov twg kev txawj ntse nthuav dav los ntawm cov tub ntxhais ua ke, ntawm ntug, thiab txhua txoj kev mus rau lub mais kawg. Los ntawm kev faib cov kev txawj ntse rau ntawm ntug (ntawm kev sib txuas lus thiab kev sib txuas lus sib txuas lus), cov kev txiav txim siab txuas ntxiv tuaj yeem ua rau lub plc). Qhov kev txawj ntse ntxiv no yuav tsum ua haujlwm tsis pub dhau los yog txo chaw nyob hauv chav ua haujlwm hauv pem teb, xav tau kev ua haujlwm nce hauv cov khoom me me.
Qhov no downsizing ntawm pcb qhov ntev qhia cov thermal kev tswj cov kev sib tw. Cov kev xaiv zoo li cov dab dej kub tsis raug tshem tawm vim tias cov chaw tuav hwm hwm hwm. Yuam - huab cua kiv cua tsis tuaj yeem siv tau, raws li kaw cov kab ke tiv thaiv cov hmoov av thiab cov paug tsis tau nkag mus. Yog li ntawd, cov kev daws teeb meem hluav taws xob yuav tsum tau ua tiav heev thaum xa lub zog siab dua thiab nyob ntawm tus hneev taw me me. Hauv kev tsim hluav taws xob muaj zog no, peb yuav daws cov kev xaiv muaj rau 20W-30W cov khoom siv hluav taws xob, piv kev ua tau zoo, thiab txiav txim siab cov kev daws teeb meem zoo tshaj plaws.
Hais Txog Kev Siv Hluav Taws Xob
Kev lag luam muaj cov ntawv thov Feature Pro 24v Nominal DC lub tsheb npav voltage, rooted nyob rau hauv cov legacy analog rov qab thiab tshuav qhov qauv kev lag luam de. Txawm li cas los xij, rau tsis - Cov khoom tseem ceeb, qhov siab tshaj plaws ua hauj lwm voltage hauv kev siv cov ntawv thov kev lag luam yuav tsum yog 36V-40V. Cov khoom siv tseem ceeb, xws li cov tswj hwm, Actuaters, thiab kev nyab xeeb qauv, yuav tsum txhawb nqa 60v (IEC611-1, thiab 6015088 txhuam). Cov khoom siv hluav taws xob feem ntau yog 3.3V thiab 5V, nrog cov dej ntws los ntawm 10mA hauv cov sensors me me rau kaum ntawm amperes nyob rau hauv cov lus tsa suab, cnc, thiab PLC daim ntawv thov. Qhov kev xaiv pom tseeb yog li qhov tseeb.
Tswj Cov Ntawv Thov: Ib Leeg Phaw (Kauj Ruam - down) voltage regulator
Hmi Vaj Huam Sib Luag: Tib neeg - tshuab cov tshuab tswj kev tsav tsheb (PLC), muab faib cov tshuab tswj (cnc)
Kev sib txuas lus modules: Digital thiab Analog thiab cov qauv siv siv cov qauv xws li cov kab kev siv, profibus, deveriii, ethet, etc.
Actuaters: motors, drives, tswj kev tsa suab, sensors: siab, ntsuas kub, kho qhov muag, thiab ntau lwm cov sensors.
Lub thoob plaws cov puck hlau feem ntau yog lub asynchronous buck hloov, raws li cov tuam txhab ua lag luam pom tias yuav tsim cov qauv asynchronous rau high- voltage cov ntawv thov. Nyob rau hauv qhov kev teeb tsa no, qhov qis -} sab rectifier diode sab nraud rau cov kev sib xyaw Circuit Court.
Rau 24V tawm tswv yim thiab 5V tso zis, cov hloov pauv cov pa nyiaj ua haujlwm ntawm lub luag haujlwm ntawm 20%. Qhov no txhais tau tias lub siab sab hauv siab- sab tshuab taag (t hauv daim duab 1) ua 20% ntawm lub sijhawm. Cov Rectifier Receifier Diode (d) Ua cov seem 80% ntawm lub sijhawm, cov nyiaj txiag rau feem ntau ntawm cov hwj chim tsis txaus.
Piv txwv li, hauv qab ntawm 4a load, SCHOTTKY Revifier diode zoo li B560C cov khoom pov thawj uas muaj voltage poob ntawm kwv yees li 0.64v. Yog li, ntawm ib qho 80% Lub Luag Haujlwm Lub voj voog, lub sijhawm poob qis (thawj poob ntawm tag nrho cov khoom lag luam) kwv yees (0.80)= 2 w.
Ntawm qhov tod tes, yog tias peb ua haujlwm ib lub archronous (Daim Duab 2), Diode yog hloov los ntawm qhov qis- sab Mauxe}}}}}}}} sab asfonifier. Peb tuaj yeem sib npaug ntawm 0.64V poob hla ntawm Diode tiv thaiv hla ntawm Mosfet Transistor lub dab dej {}}}}}} source source ntawm cov r_ (DS) (ntawm).
Daim duab 1. Asynchronous Buck Hloov Pack Converter
Hauv peb qhov piv txwv, tus Mosfet RJK0651DPB nta RDS (rau) ntawm tsuas yog 11 mω, nrog pob loj zoo ib yam li cov tshuaj schottky li. Qhov no ua rau muaj volleage poob ntawm tsuas yog (11 mω) {{{5} {{5} {{{{9 {mw.
Mosfet lub zog yog kwv yees li ntawm 14 lub sijhawm qis dua li Schottky lub zog poob ntawm tag nrho thauj! Kom meej meej, txoj kev xav kom ua kom txo tau kev noj hluav taws xob tsawg yuav ua haujlwm synchronous kev ntsuas.
Daim duab 2. Cov pob zeb sib txuas sib txuas
Txhawm rau kom tsawg ntawm cov hluav taws xob tag nrho Lawv kuj yuav tsum ua haujlwm ntawm cov haujlwm siab kom tso cai rau kev siv cov neeg ua txhaum me me thiab capacitors.
Daim Duab 3. Raug ntawv thov Circuit Court rau qhov max17536 24 vin / 500} vin / 500out, 4a synchronous phaw Pack hloov
Lub Max17536 thiab ib qho kev daws teeb meem asynchronous ntawm cov specifications tau tshaj tawm hauv daim duab 4. Rau cov khoom siv, xeem ntawv yog 24V tawm tswv yim thiab 5S tawm. Raws li tau txais, Maxim cov kev daws teeb meem synchronous pom tau ntau dua kev ua haujlwm thoob plaws txhua yam. Ntawm tag nrho cov load (4A), MAXIM SQUCHONUS daws tau ntau dua 92% equonconency tau mus txog}%, sawv cev rau qhov sib txawv ntau tshaj 6%.
Daim duab 4. Kev ua haujlwm ntawm synchronous thiab asynchronous buck
Tag
Thaum hais txog kev noj cov hwj huam muaj kev cov kev teeb meem hauv kev lag luam, MAX17536 nthuav tawm cov kev siv zog sib xws rau cov tswv yim zoo voltages. Cov xwm txheej no ua kom pom qhov ua tau zoo ntxiv, txo hwj chim zog dissipation.
