Ob peb xyoos dhau los, ib tug engineer los ntawm lub tuam txhab German automation hu rau peb nrog ib qho teeb meem uas twb tau noj lub lim tiam ntawm kev daws teeb meem.
Lub rooj tsavxwm tswj tau ua haujlwm zoo kawg nkaus thaum lub sijhawm kuaj. Txhua qhov hluav taws xob tau raug, tus tsav lub rooj vag teb raws li qhov xav tau, thiab oscilloscope tau pom cov cim hloov pauv huv. Txawm li cas los xij, ib zaug cov cuab yeej tau teeb tsa ntawm cov kab ntau lawm, kev sib txuas lus tsis zoo pib tshwm sim. Qee lub sij hawm tus tsav tsheb IGBT yuav hloov tsis raug. Qee lub sij hawm cov teeb liab digital tuaj txog distorted. Qee zaum, tag nrho cov kev tswj hwm yuav rov pib dua yam tsis muaj kev ceeb toom.
Tom qab tshuaj xyuas lub voj voog, peb tau hais kom hloov ib qho zoo li qhov tsis tseem ceeb -pulse transformer.
Cov neeg siv khoom xav tsis thoob.
"Nws tsuas yog xa cov teeb liab xwb," tus engineer teb.
Nyob rau hauv kev muaj tiag, qhov "me me transformer" yog lub luag hauj lwm rau kev tswj cov mem tes kis tau tus mob kom raug thaum hluav taws xob cais ob sib txawv circuits khiav hauj lwm nyob rau hauv tag nrho cov voltage sib txawv. Thaum lub transformer tau hloov dua tshiab rau qhov tseeb hloov zaus thiab mem tes yam ntxwv, cov teeb meem kev sib txuas lus tau ploj mus tag nrho.
Cov kev paub zoo li no qhia peb tias pulse transformers feem ntau underestimated. Tsis zoo li cov pa hluav taws xob hloov pauv, lawv tsis muaj nyob kom xa cov zog loj. Lawv txoj haujlwm yog qhov muag heev. Lawv hloov ceev hluav taws xob pulses kom raug, khaws cov teeb liab kev ncaj ncees, thiab muab hluav taws xob cais qhov twg txawm me ntsis distortion tuaj yeem cuam tshuam kev ua haujlwm ntawm tag nrho cov kab ke.
Ntawm Wuxi Huipu Electronics Co., Ltd., peb feem ntau piav qhia rau cov neeg siv khoom tias lub tshuab hluav taws xob mem tes yuav tsum raug saib raws li lub teeb liab kis tau tus mob ntau dua li lub zog hloov hluav taws xob. Txawm hais tias ob qho tib si siv electromagnetic induction, lawv lub hom phiaj tsim yog txawv kiag li.
Hloov pauv tsis tu ncua hloov hluav taws xob, lub tshuab hluav taws xob hloov pauv hloov pauv luv luv - lub sijhawm hluav taws xob pulses ntawm ib lub voj voog mus rau lwm qhov thaum tswj xyuas qhov zoo ntawm waveform fidelity. Txawm hais tias lub mem tes kav ntev li ob peb lub microseconds lossis tsuas yog ob peb nanoseconds, lub transformer yuav tsum rov ua dua nws nrog kev cuam tshuam tsawg. Yog hais tias lub mem tes hloov pauv, qeeb lossis tsis muaj zog, qhov kev txais hluav taws xob tuaj yeem txhais lub teeb liab tsis raug.
Qhov kev xav tau no piav qhia vim li cas cov pulse transformers muaj nyob rau hauv cov ntawv thov uas lub sijhawm tseem ceeb. Rooj vag tsav tsheb circuits rau IGBTs thiab MOSFETs cia siab rau lawv kom xa cov lus txib hloov huv si. Ethernet kev sib txuas lus modules siv tshwj xeeb tsim pulse transformers los cais cov khoom siv network thaum khaws cia siab - cov ntaub ntawv xa mus ceev. Lawv kuj tau siv dav hauv kev lag luam automation, cov cuab yeej sib txuas lus digital, hloov cov khoom siv hluav taws xob, kev kho mob hluav taws xob thiab hluav taws xob tswj tshuab.
Ib qho kev xav tsis zoo uas peb feem ntau ntsib yog tias ib qho me me siab - zaus transformer tuaj yeem hloov lub mem tes transformer. Hmoov tsis zoo, qhov kev xav no feem ntau ua rau kev poob siab. Pulse transformers yog tsim los nrog kev tswj nruj dua ntawm kev xau inductance, faib cov peev txheej thiab bandwidth. Lawv cov cores sib nqus, cov qauv winding thiab cov txheej txheem rwb thaiv tsev yog txhua yam ua kom zoo rau cov lus teb sai sai dua li qhov siab tshaj plaws hloov hluav taws xob.
Kev xaiv ntawm cov tub ntxhais hlau nplaum ua lub luag haujlwm tseem ceeb. Cov ntaub ntawv ferrite feem ntau xaiv vim lawv teb tau zoo ntawm kev hloov pauv ntau zaus thaum txo cov tub ntxhais poob qis. Txawm li cas los xij, xaiv ferrite tsis yog ib qho teeb meem ntawm kev xaiv qhov loj me me. Cov qib ferrite sib txawv muaj qhov sib txawv permeability, cov yam ntxwv zaus thiab tus cwj pwm saturation. Lub transformer uas ua tau zoo nyob rau hauv kev sib txuas lus interface yuav coj txawv txawv nyob rau hauv ib tug IGBT rooj vag tsav tsheb tsuas yog vim hais tias cov pulse yam ntxwv tau hloov.
Winding tsim yog qhov tseem ceeb sib npaug. Txij li cov pulse transformers kis tau siab - cov cim ceev es tsis yog lub zog tas mus li, kev txo qis inductance yuav dhau los ua lub hom phiaj tseem ceeb. Engineers feem ntau siv interleaved winding cov tswv yim los txhim kho coupling ntawm thawj thiab theem nrab windings thaum txo cov teeb liab distortion. Cov kev hloov me me hauv kev teeb tsa winding tuaj yeem txhim kho lub sijhawm nce, txo qis overshoot thiab nce tag nrho cov teeb liab zoo.
Kev sib cais kev ua tau zoo yog lwm qhov laj thawj pulse transformers tseem nrov txawm tias muaj cov optocouplers thiab digital isolators. Hauv ntau daim ntawv thov kev lag luam, kev sib cais hluav taws xob tsis yog qhov xav tau xwb - nws yog qhov tseem ceeb. High- cov khoom siv hluav taws xob hloov hluav taws xob feem ntau yuav tsum muaj tsawg- voltage tswj circuits kom nyob twj ywm hluav taws xob cais tawm ntawm cov khoom siv hluav taws xob. Lub tshuab hluav taws xob tsim hluav taws xob tsim tau ua tiav qhov no yam tsis tas yuav tsum muaj kev sib txuas hluav taws xob ncaj qha, txhim kho kev nyab xeeb thiab kev ntseeg tau ntawm lub cev.
Thaum lub sijhawm txhim kho kev cai, ib qho ntawm thawj cov lus nug uas peb pab pawg engineering nug tsis yog "Yuav ua li cas hloov pauv koj xav tau?" Xwb, peb nug txog lub mem tes nws tus kheej. Dab tsi yog qhov hloov pauv zaus? Lub sijhawm nce thiab poob sai npaum li cas? Yuav tsum muaj kev sib cais voltage dab tsi? Lub luag haujlwm ntawm lub voj voog uas xav tau yog dab tsi? Kev nkag siab txog cov kev txwv no tso cai rau peb txhawm rau txhim kho qhov hloov pauv tshwj xeeb rau nws qhov chaw ua haujlwm es tsis yog qhov sib piv cov hluav taws xob tshwj xeeb.
Kev tsim khoom zoo yog qhov tseem ceeb sib npaug vim tias cov teeb liab transformers tawm hauv chav me me rau qhov tsis sib xws. Kev hloov pauv me ntsis hauv winding geometry, rwb thaiv tsev tso lossis ferrite sib dhos tuaj yeem hloov cov yam ntxwv hluav taws xob txaus los cuam tshuam rau kev ua haujlwm ntawm lub cev. Vim li no, txhua tus pulse transformer uas tsim los ntawm Wuxi Huipu Electronics Co., Ltd. tau dhau los ua kev ntsuas hluav taws xob, suav nrog kev txheeb xyuas qhov sib piv, ntsuas inductance, ntsuas kev ntsuas hluav taws xob thiab ntsuas waveform ua ntej xa khoom. Kev sib raug zoo ntawm cov khoom tsim khoom yog qhov tseem ceeb tshwj xeeb rau OEM cov tuam txhab tsim ntau txhiab tus tswj hwm zoo ib yam txhua lub hlis.
Raws li kev hloov zaus txuas ntxiv nce ntxiv thiab cov khoom siv hluav taws xob ua lag luam ua ntau dua, pulse transformers tseem tseem ceeb txawm tias kev nce qib sai hauv semiconductor thev naus laus zis. Lawv lub peev xwm los muab cov teeb liab sib txuas, kev sib cais hluav taws xob thiab kev ntseeg siab ua rau lawv yog ib qho ntawm cov khoom siv uas tsis tshua tau txais kev saib xyuas ntau heev -kom txog thaum lawv tsis ua haujlwm raug.
Engineers feem ntau tsom rau cov processors, controllers thiab switching devices vim hais tias lawv yog cov feem ntau pom qhov chaw ntawm lub Circuit Court. Txawm li cas los xij nyob rau hauv ntau lub tshuab hluav taws xob siab - ceev ceev, nws yog lub tshuab hluav taws xob mem tes ntsiag to ua haujlwm hauv keeb kwm yav dhau uas ua kom txhua qhov kev hloov pauv, txhua lub teeb liab sib txuas lus thiab txhua lub mem tes tswj tau tuaj txog raws nraim thaum twg thiab qhov twg nws yuav tsum. Tias yog vim li cas vim li cas xaiv txoj cai pulse transformer tau dhau los ua ib feem tseem ceeb ntawm kev tsim cov khoom siv hluav taws xob niaj hnub txhim khu kev qha.
