Ib qho ntawm cov lus nug peb hnov ntau zaus los ntawm cov neeg siv khoom tshiab tsis yog hais txog tus nqi lossis lub sijhawm xa khoom. Nws yog ib qho yooj yim xav tsis thoob:
"Kuv yuav ua li cas thiaj paub yog tias kuv xaiv txoj cai pulse transformer?"
Cov lus nug feem ntau tuaj tom qab ib yam dab tsi twb ploj mus lawm.
Ob peb xyoos dhau los, tus kws tshaj lij los ntawm lub tuam txhab hluav taws xob hluav taws xob hauv tebchaws Poland tau hu Wuxi Huipu Electronics Co., Ltd. Lawv lub rooj vag tsav tsheb Circuit Court ua haujlwm zoo kawg nkaus thaum txhim kho. Oscilloscope waveforms saib huv si, hloov cov cuab yeej ua haujlwm ib txwm, thiab cov qauv ua tiav tiav kev sim ua haujlwm. Txawm li cas los xij, txhua zaus cov khoom nkag mus rau cov ntawv pov thawj, electromagnetic cuam tshuam dhau qhov kev txwv.
Pab pawg neeg tsim khoom tau hloov tus tswj hwm, hloov kho PCB layout thiab txawm rov tsim EMI lim. Tsis muaj dab tsi daws qhov teeb meem.
Thaum kawg, lawv hais kom peb los tshuaj xyuas cov pulse transformer.
Qhov teeb meem tau tshwm sim tsis yog Circuit Court kiag li. Lub transformer tau raug xaiv raws li kev hloov pauv thiab kev sib cais voltage ib leeg. Nws cov dej xau inductance tau nce siab dua li daim ntawv thov tuaj yeem zam, tsim cov kev hloov pauv uas nthuav dav thoob plaws hauv kev tsav tsheb. Thaum lub transformer winding qauv raug kho dua tshiab, qhov teeb meem EMI ploj mus yam tsis muaj kev hloov pauv lwm yam.
Cov kev paub zoo li no tau qhia peb ib zaj lus qhia tseem ceeb: xaiv lub pulse transformer tsis tshua muaj kev ncaj ncees raws li kev sib piv cov hluav taws xob tshwj xeeb.
Ntau tus engineers pib los ntawm kev saib ntawm qhov sib piv. Txawm hais tias qhov parameter tseem ceeb, nws tsuas yog qhia ib feem ntawm zaj dab neeg. Lub pulse transformer yog lub luag haujlwm rau kev tsim cov hluav taws xob sai sai nrog kev cuam tshuam tsawg. Yog tias lub tshuab hloov pauv tsis tuaj yeem khaws cov duab ntawm cov mem tes, qhov tau txais Circuit Court yuav hnov mob qeeb dhau lossis hloov ntawm lub sijhawm tsis raug. Hauv siab -cov tshuab hluav taws xob ceev, lub sijhawm yuam kev ntsuas hauv nanoseconds tuaj yeem dhau los ua teeb meem kev ntseeg siab tiag tiag tom qab ntau txhiab teev ua haujlwm.
Thawj qhov uas peb feem ntau tham nrog cov neeg siv khoom tsis yog lub transformer nws tus kheej, tab sis lub voj voog ncig nws. Puas yog nws tsav IGBT? Puas yog nws cais Ethernet interface? Puas yog ib feem ntawm kev hloov hluav taws xob lossis kev sib txuas lus digital? Txawm hais tias tag nrho cov ntawv thov no siv pulse transformers, cov kev xav tau hluav taws xob sib txawv kiag li. Lub transformer uas ua tau zoo nyob rau hauv lub network interface tej zaum yuav unsuitable nkaus rau lub rooj vag tsav tsheb khiav ntawm high switching tam sim no.
Hloov zaus yog lwm yam uas tsim nyog tau txais kev saib xyuas ntau dua li nws tau txais ntau zaus. Raws li cov zaus nce, qhov sib nqus core poob, to inductance thiab winding capacitance txhua tus pib cuam tshuam kev ua tau zoo dua. Qee lub sij hawm peb pom cov neeg siv khoom rov siv dua qhov qub transformer tsim tsuas yog vim qhov ntsuas hluav taws xob tseem zoo ib yam. Hmoov tsis zoo, kev hloov pauv ntau zaus thaum tawm hauv cov qauv sib nqus tsis hloov pauv tsis tshua muaj txiaj ntsig zoo. Cov zaus ntau dua qhov kev xav tau sib txawv ntawm ob qho tib si ferrite cov ntaub ntawv thiab cov txheej txheem winding.
Cov khoom siv tseem ceeb nws tus kheej feem ntau raug saib xyuas vim tias cov ferrite cores zoo li sab nraud. Nyob rau hauv kev muaj tiag, txawv ferrite formulations coj txawv txawv nyob rau hauv kev hloov kub thiab zaus. Xaiv cov khoom siv tsis raug yuav tsis ua rau tsis ua haujlwm tam sim ntawd, tab sis nws tuaj yeem txo qhov ua tau zoo, ua kom cov teeb liab distortion thiab tsim kom tsis muaj thermal stress. Thaum lub sij hawm kev cai tsim tej yaam num, peb cov engineering pab neeg soj ntsuam kev khiav hauj lwm zaus, ambient kub thiab lub voj voog lub luag hauj lwm ua ntej pom zoo rau ib tug tsim nyog cov ntaub ntawv es tsis xaiv ib tug raws li nyob rau hauv cov khoom.
Kev rho tawm voltage yog qhov tseem ceeb sib npaug, tshwj xeeb tshaj yog nyob rau hauv kev lag luam automation, kev kho mob hluav taws xob thiab cov khoom siv hluav taws xob hloov hluav taws xob. Ntau tus neeg siv khoom pib tsom mus rau cov teeb liab kis tau tus mob thaum tsis nco qab tias lub tshuab hluav taws xob pulse feem ntau ua haujlwm tseem ceeb ntawm kev nyab xeeb ntawm high-voltage thiab low-voltage circuits. Kev xaiv cov rwb thaiv tsev tsim nyog tsis yog tsuas yog hais txog kev ua raws li cov cai tswj hwm- nws cuam tshuam ncaj qha rau lub sijhawm ntev - kev ntseeg siab nyob rau hauv kev ntxhov siab tsis tu ncua.
Mechanical loj tuaj yeem dhau los ua qhov kev txwv tsis pub siv. Cov engineers ib txwm xav tau cov khoom siv hluav taws xob sib txuas, tab sis txo qis qhov ntsuas hluav taws xob ntau dhau heev dhau los feem ntau tawm hauv chav me me rau kev tswj xyuas thermal los yog qhov zoo winding geometry. Peb ib txwm txhawb cov neeg siv khoom kom txhim kho qhov loj me ntawm qhov hloov pauv ntau dua li txo qis. Ib qho sib nqus loj me me tuaj yeem txhim kho kev ua haujlwm tau zoo thiab txo qis kev ua haujlwm kub thoob plaws lub neej ntawm cov khoom siv.
Ib yam uas paub qhov txawv ntawm cov tuam txhab kev paub txog kev hloov pauv los ntawm cov khoom lag luam zoo tib yam yog lub peev xwm los txhim kho cov qauv winding rau ib daim ntawv thov tshwj xeeb. Pulse transformers yog qhov tsis tshua muaj siab rau cov pa tawm inductance thiab faib cov capacitance. Cov yam ntxwv no tau txiav txim siab tsis yog los ntawm kev suav hluav taws xob nkaus xwb tab sis kuj yog los ntawm kev siv cov windings li cas ntawm lub cev nyob rau hauv lub transformer. Ob qhov kev hloov pauv nrog qhov sib npaug sib npaug tuaj yeem tsim qhov sib txawv waveform zoo vim tias lawv cov qauv winding tau tsim txawv.
Ntawm Wuxi Huipu Electronics Co., Ltd., qhov no yog ib qho ntawm cov laj thawj uas peb nquag pom zoo rau kev cai mem tes transformer kev daws teeb meem rau OEM cov neeg siv khoom es tsis txhob ntawm cov khoom catalog txheem. Txhua qhov hluav taws xob hluav taws xob muaj nws tus cwj pwm hloov pauv, lub sijhawm xav tau thiab ib puag ncig kev ua haujlwm. Tsim cov transformer nyob ib ncig ntawm cov xwm txheej no feem ntau xa tau ntev dua - kev ua tau zoo dua li kev yuam lub voj voog kom hloov mus rau lub tshuab hloov hluav taws xob.
Qhov zoo sib xws yuav tsum tsis txhob raug saib xyuas ib yam nkaus. Hauv kev tsim qauv, ib qho transformer tuaj yeem ua tau zoo. Kev tsim khoom loj, txawm li cas los xij, qhia txog kev sib tw sib txawv. Variations nyob rau hauv winding nro, ferrite los ua ke los yog rwb thaiv tsev positioning yuav maj mam hloov transformer yam ntxwv ntawm ntau lawm batch. Tias yog vim li cas txhua lub tshuab hluav taws xob pulse uas tsim nyob rau hauv peb qhov chaw tau txais kev ntsuas hluav taws xob zoo, suav nrog kev kuaj xyuas inductance, Hi-Kev ntsuas lub lauj kaub, kev ntsuas waveform thiab kev soj ntsuam rwb thaiv tsev ua ntej xa khoom.
Tom qab ntau xyoo ntawm kev ua haujlwm nrog cov tuam txhab hluav taws xob hluav taws xob thoob ntiaj teb, peb tau pom tias xaiv txoj cai pulse transformer tsis tshua muaj kev nrhiav tau qhov tshwj xeeb tshaj plaws. Nws yog hais txog kev nrhiav tus transformer uas nws tus cwj pwm hluav taws xob cuam tshuam rau lub voj voog ntawm kev ua haujlwm tiag tiag.
Qhov zoo tshaj plaws pulse transformer tsis tas yuav yog qhov tsawg tshaj plaws, tus nqi qis tshaj lossis ib qho nrog cov ntaub ntawv zoo tshaj plaws. Nws yog ib qho uas ntsiag to ua ntau lab ntawm kev hloov pauv txhua hnub yam tsis muaj kev qhia txog kev sib txawv, kev kub ntxhov ntau dhau lossis kev txhawj xeeb txog kev ntseeg siab. Hauv kev tsim hluav taws xob niaj hnub no, qhov kev ruaj ntseg zoo li no tsis tshua muaj tshwm sim los ntawm lub caij nyoog - nws los ntawm kev nkag siab txog daim ntawv thov ua ntej thiab xaiv qhov hloov pauv thib ob.
