Fais fab Module Taw qhia - Fais fab Module DC Chopper
Taw qhia
Hloov cov khoom siv hluav taws xob tuaj yeem muab faib ua ob pawg: AC / DC thiab DC / DC. DC / DC converter tam sim no tau hloov kho, thiab cov txheej txheem tsim tshuab thiab cov txheej txheem tsim khoom tau paub tab thiab tsim qauv hauv tsev thiab txawv teb chaws, thiab tau lees paub los ntawm cov neeg siv khoom. Lub modularization ntawm AC / DC, vim nws tus kheej cov yam ntxwv, ntsib ntau nyuaj technical thiab txheej txheem tsim teeb meem nyob rau hauv tus txheej txheem ntawm modularization.
DC txiav
DC / DC hloov dua siab tshiab yog hloov pauv DC qhov hluav taws xob ruaj khov rau hauv qhov sib txawv DC voltage, tseem hu ua DC chopping. Muaj ob hom kev ua haujlwm ntawm lub tshuab chopper, ib qho yog pulse width modulation mode, Ts tsis hloov pauv, thiab tus tuj hloov pauv (ntau), thiab lwm yam yog hom zaus hloov pauv, tuj tsis hloov, thiab Ts hloov pauv (yooj yim los tsim kev cuam tshuam). Nws cov Circuit Court tshwj xeeb muaj xws li cov hauv qab no:
(1) Buck Circuit Court - kauj ruam-down chopper, nws cov zis nruab nrab voltage Uo tsawg tshaj li qhov input voltage Ui, thiab polarity yog tib yam.
(2) Boost Circuit Court - boost chopper, nws cov zis nruab nrab voltage Uo yog ntau tshaj qhov input voltage Ui, thiab polarity yog tib yam.
(3) Buck-Boost Circuit Court - step-down los yog step-up chopper, nws cov zis nruab nrab voltage Uo yog ntau tshaj los yog tsawg tshaj input voltage Ui, lub polarity yog opposite, thiab cov inductance yog kis.
(4) Cuk Circuit Court - step-down los yog step-up chopper, nws cov zis nruab nrab voltage Uo yog ntau dua los yog tsawg tshaj qhov input voltage UI, lub polarity yog opposite, thiab lub capacitance kis tau tus mob.
AC / DC
AC / DC hloov dua siab tshiab yog hloov AC rau DC, thiab nws lub zog ntws tuaj yeem ua ob txoj kev. Lub hwj chim ntws los ntawm lub hwj chim qhov chaw mus rau lub load yog hu ua "rectification", thiab lub zog khiav ntawm lub load rov qab mus rau lub hwj chim qhov chaw yog hu ua "active inverter". Lub tswv yim ntawm AC / DC converter yog 50 / 60Hz alternating tam sim no. Vim hais tias nws yuav tsum tau kho thiab lim, ib qho loj lim capacitor yog qhov tseem ceeb. Tib lub sijhawm, vim yog cov qauv kev nyab xeeb (xws li UL, CCEE, thiab lwm yam) thiab EMC cov lus qhia Cov kev txwv ntawm AC / DC fais fab mov (xws li IEC, FCC, CSA), AC input sab yuav tsum ntxiv EMC lim thiab siv cov khoom uas ua tau raws li cov qauv kev nyab xeeb, uas txwv qhov kev siv hluav taws xob me me ntawm AC / DC fais fab mov. Tsis tas li ntawd, vim muaj qhov siab zaus, qhov siab voltage, thiab tam sim no loj Qhov kev hloov pauv ua rau nws nyuaj dua los daws qhov teeb meem ntawm EMC electromagnetic compatibility, uas tseem tso siab rau cov kev xav tau siab rau kev tsim cov khoom siv hauv high-density installation circuits. Rau tib lub laj thawj, qhov hluav taws xob siab thiab cov hloov pauv siab tam sim no nce lub zog siv thiab txwv AC / DC converter modularization txheej txheem, yog li nws yog ib qho tsim nyog yuav tsum tau txais kev siv lub zog ua kom zoo tshaj plaws tsim qauv kom nws cov haujlwm ua haujlwm tau ncav cuag qee qhov kev txaus siab.
Kev hloov pauv AC / DC tuaj yeem muab faib ua ib nrab-yoj Circuit Court thiab puv-yoj Circuit Court raws li txoj kev xaim ntawm lub voj voog. Raws li tus naj npawb ntawm cov theem fais fab, nws tuaj yeem muab faib ua ib theem, peb theem thiab ntau theem. Raws li kev ua haujlwm quadrant ntawm lub voj voog, nws tuaj yeem muab faib ua ib lub quadrant, ob lub quadrant, peb quadrant, thiab plaub quadrant.
qhov zoo
Yooj yim tsim. Tsuas yog ib lub hwj chim module yog xav tau, ua ke nrog ob peb yam sib cais, kom tau txais lub zog.
Shorten lub voj voog kev loj hlob. Module fais fab mov feem ntau muaj ntau yam kev tawm tswv yim thiab tso zis. Cov neeg siv kuj tuaj yeem rov ua qhov superposition lossis cross superposition los tsim ib lub tsev thaiv kev sib xyaw ua ke kom paub txog ntau yam kev tawm tswv yim thiab cov khoom siv, uas txo cov qauv tsim lub sijhawm.
Hloov pauv hloov. Yog tias cov khoom tsim yuav tsum tau hloov pauv, nws tsuas yog tsim nyog los hloov lossis txuas lwm lub zog tsim nyog module nyob rau hauv tib lub sijhawm.
Tsawg cov kev cai. Modular cov khoom siv hluav taws xob feem ntau yog nruab nrog cov qauv ua ntej-kawg, cov khoom siv hluav taws xob sib xyaw ua ke thiab lwm yam khoom siv, yog li ua rau cov khoom siv hluav taws xob tsim tau yooj yim dua.
Lub plhaub ntawm lub module fais fab mov muaj peb-hauv-ib tus qauv ntawm lub dab dej kub, lub tshuab hluav taws xob thiab lub plhaub, uas paub txog cov txheej txheem txias txias ntawm lub module fais fab mov thiab ua rau qhov kub ntawm cov khoom siv hluav taws xob mus rau qhov tsawg kawg nkaus tus nqi. Nyob rau tib lub sij hawm, lub module fais fab mov yog endowed nrog ib tug luxurious ntim.
Zoo thiab txhim khu kev qha. Module fais fab mov feem ntau yog tsim los ntawm tag nrho automation thiab nruab nrog high-tech ntau lawm technology, yog li qhov zoo yog ruaj khov thiab txhim khu kev qha.
Kev siv ntau yam: cov khoom siv hluav taws xob module tuaj yeem siv dav hauv ntau yam kev lag luam thiab kev ua neej, xws li aerospace, locomotives thiab nkoj, riam phom tub rog, kev tsim hluav taws xob thiab kev faib tawm, kev xa ntawv thiab kev sib txuas lus, metallurgical mines, kev tswj tsis siv neeg, khoom siv hauv tsev. , cov cuab yeej thiab cov kev tshawb fawb tshawb fawb thwmsim, thiab lwm yam. Nws plays lub luag hauj lwm tseem ceeb irreplaceable nyob rau hauv lub tshav pob ntawm kev ntseeg siab thiab high technology.
