Khoom nta thiab cov ntsiab cai ntawm High zaus Switching fais fab mov
Cov khoom no txais yuav cov khoom lag luam nto moo txawv teb chaws thiab thoob ntiaj teb siab tshaj plaws-bridge inverting converter thev naus laus zis los ua cov txheej txheem precision, uas ua rau kev ua haujlwm ntawm tag nrho lub tshuab ruaj khov thiab zoo dua txhim khu kev qha. 2 Lub tshuab tag nrho muaj overvoltage, overcurrent, overtemperature, luv luv Circuit Court, tsis muaj theem tsis siv neeg tiv thaiv tswb muaj nuj nqi thiab muag muag pib muaj nuj nqi. Nws tseem tuaj yeem nruab nrog lub sijhawm tswj thiab lub computer interface. 3. Lub DC tso zis waveform yog ib tug high-frequency square nthwv dej nrog ib tug ripple coefficient ntawm tsawg tshaj li los yog sib npaug rau 1 feem pua, uas yuav ua rau kom tus xov tooj ntawm plating, tsis kam passivation, txhim khu lub gloss ntawm txheej txheej thiab cov tub ntxhais drilling degree ntawm lub kaum sab xis ntawm lub plating. Nws tseem tuaj yeem txo qhov poob ntawm cov ntaub ntawv raw thiab ua tau raws li ntau yam tshwj xeeb ntawm kev lag luam electroplating. 4SFG series txais cov cua txias tsim thiab yooj yim rau nruab. Thiab nruab nrog cov chaw taws teeb tswj, yooj yim rau kev khiav lag luam. Lub tshuab tuaj yeem qhib thiab tawm nrog kev thauj khoom, txo cov txheej txheem cumbersome ntawm kev hloov kho. 5. Qhov loj me me thiab lub teeb hauv qhov hnyav, tag nrho lub tshuab yog tsim los ntawm txhua qhov kev tiv thaiv kev tiv thaiv corrosion, uas txhim khu kev tiv thaiv corrosion ntawm cov khoom thiab ua rau lub neej ntev kev pab cuam. 6 Kev ua haujlwm siab, txuag hluav taws xob, ua haujlwm ua haujlwm siab tshaj 90 [ feem pua ], txhua qhov voltage-tam sim no piv yog ib txwm sib luag. Kev poob ntawm qhov hluav taws xob tswj hluav taws xob thiab lub ntsiab transformer ntawm cov tsoos rectifier raug tshem tawm, kev txuag hluav taws xob ntau dua 35 [ feem pua ], thiab tus nqi ntawm electroplating tau txo qis heev. Nws yog qhov ua tau zoo tshaj plaws xaiv rau kev lag luam kho qhov chaw.
Txoj cai ntawm high zaus switching fais fab mov
Lub ntsiab Circuit Court
Tag nrho cov txheej txheem ntawm AC grid input thiab DC tso zis muaj xws li: 1. Input filter: nws txoj haujlwm yog lim cov clutter uas twb muaj lawm nyob rau hauv daim phiaj, thiab tib lub sij hawm tiv thaiv cov clutter generated los ntawm lub tshuab los ntawm kev pub rov qab mus rau pej xeem daim phiaj. 2. Rectification thiab filtering: daim phiaj AC yog ncaj qha rectified mus rau ib tug smoother DC rau theem tom ntej ntawm transformation. 3. Inversion: Hloov cov rectified direct tam sim no mus rau high-frequency alternating tam sim no, uas yog ib feem ntawm high zaus. Qhov ntau zaus, qhov me me ntawm qhov ntim, qhov hnyav thiab qhov tso zis zog. 4. Tso zis rectification thiab filtering: Raws li load yuav tsum, muab ruaj khov thiab txhim khu kev qha DC fais fab mov.
Tswj Circuit Court
Ntawm qhov tod tes, cov qauv raug coj los ntawm qhov tso zis davhlau ya nyob twg, piv nrog cov txheej txheem teeb tsa, thiab tom qab ntawd lub inverter yog tswj los hloov nws zaus los yog mem tes dav kom ua tiav cov zis ruaj khov; Lub Circuit Court tswj ua ntau yam kev tiv thaiv kev ntsuas ntawm tag nrho lub tshuab.
kuaj xyuas Circuit Court
Ntxiv nrog rau kev muab ntau yam tsis sib xws hauv kev tiv thaiv Circuit Court hauv kev ua haujlwm, nws kuj tseem muab ntau yam kev ntsuas ntsuas cov ntaub ntawv.
Pab txhawb zog
Muab lub zog rau cov kev xav tau sib txawv ntawm txhua lub voj voog ib leeg. Lub hauv paus ntsiab lus ntawm kev tswj kev tswj thiab qhov hluav taws xob stabilization Qhov hloov K yog rov qhib thiab tawm ntawm ib lub sijhawm luv luv. Thaum lub hloov K yog qhib, lub hwj chim input E yog nkag mus rau lub load RL los ntawm qhov hloov K thiab lim circuit. Thaum lub sijhawm hloov pauv tag nrho, lub zog E Muab lub zog rau lub nra; Thaum lub qhov hluav taws xob K raug muab tua, cov khoom siv hluav taws xob nkag E cuam tshuam cov khoom siv hluav taws xob. Nws tuaj yeem pom tau tias lub zog muab los ntawm cov khoom siv hluav taws xob nkag mus rau cov khoom thauj yog cuam tshuam. Txhawm rau muab lub zog txuas ntxiv mus rau qhov thauj khoom, kev hloov pauv kev tswj hwm lub zog yuav tsum muaj cov khoom siv hluav taws xob cia. Thaum lub qhov hluav taws xob qhib, ib feem ntawm lub zog yog khaws cia. Tso rau lub load thaum disconnected. Nyob rau hauv daim duab, lub Circuit Court muaj li ntawm inductor L, capacitor C2 thiab diode D muaj cov haujlwm no. Lub inductance L yog siv los khaws lub zog. Thaum lub tshuab hluav taws xob raug kaw, lub zog khaws cia hauv inductance L raug tso tawm mus rau lub load los ntawm diode D, kom lub load tuaj yeem tau txais lub zog tas li thiab ruaj khov. Vim tias lub diode D ua rau cov load tam sim no tsis tu ncua, nws yog hu ua freewheeling. diode. Qhov nruab nrab qhov hluav taws xob EAB ntawm AB tuaj yeem qhia tau los ntawm cov qauv hauv qab no: EAB=TON / T * E Hauv cov qauv, TON yog lub sijhawm thaum hloov pauv txhua lub sijhawm, thiab T yog lub luag haujlwm ntawm lub voj voog. hloov rau thiab tawm (uas yog, qhov hloov ntawm lub sijhawm TON thiab tawm ntawm lub sijhawm TOFF). Nws tuaj yeem pom los ntawm cov qauv uas qhov nruab nrab tus nqi ntawm qhov hluav taws xob ntawm A thiab B kuj tseem yuav hloov pauv los ntawm kev hloov qhov sib piv ntawm lub sijhawm ntawm kev hloov mus rau lub voj voog ua haujlwm. Yog li ntawd, cia li kho qhov sib piv ntawm TON thiab T nrog kev hloov ntawm lub load thiab cov input fais fab mov voltage yuav ua rau cov zis voltage V0 nyob twj ywm tib yam. Hloov lub sij hawm TON thiab lub luag hauj lwm voj voog piv txhais tau tias hloov lub luag hauj lwm voj voog ntawm lub mem tes. Txoj kev no hu ua "time ratio control"
