Kev Ntsuam Xyuas Ntawm Cov trends Thiab cov ntawv thov hauv Laminated Busbar Technology: Tsawg-Inductance Connection Solutions Rau High-Power Electrical Systems

 

Nrog rau kev loj hlob sai ntawm cov haujlwm xws li tsheb tshiab lub zog (NEVs), lub zog khaws cia, cov khoom siv hluav taws xob, thiab cov phiajcim ntse, cov khoom siv hluav taws xob hluav taws xob tau hloov mus rau qhov muaj zog dua, kev ntsuas hluav taws xob ntau dua, thiab ntau cov qauv sib txuas. Tawm tsam qhov keeb kwm yav dhau los no, kev sib txuas ntawm cov kab ke ib txwm muaj thiab cov qauv tooj liab busbar tau nce zuj zus tuaj yeem ua tsis tau raws li cov kev xav tau ntawm cov ntawv thov uas muaj kev hloov pauv ceev, siab - zaus ua haujlwm, thiab kev tswj xyuas qhov chaw thermal.

 

Raws li cov khoom siv hluav taws xob sib txuas ua tau zoo, lub laminated busbar- tsim los ntawm laminating ntau txheej ntawm cov neeg xyuas pib thiab cov ntaub ntawv insulating rau hauv cov qauv kev sib koom ua ke- txo qis cov kab mob parasitic inductance hauv lub voj tam sim no thiab txhim kho cov lus teb ceev thiab kev ua haujlwm ruaj khov. Tam sim no, cov thev naus laus zis no tau siv dav hauv NEV hluav taws xob tsav tsheb, lub zog cia hloov pauv, kev lag luam inverters, kev tsheb nqaj hlau thauj mus los, thiab siab - cov khoom siv hluav taws xob.

 

Piv nrog rau cov kev sib txuas ib txwm siv, qhov zoo tshaj plaws ntawm laminated busbars nyob rau hauv kev ua kom zoo ntawm txoj kev sib kis tam sim no. Los ntawm nruj stacking zoo thiab tsis zoo conductors (los yog conductors ntawm txawv muaj peev xwm), qhov tam sim no voj cheeb tsam yog txo; Qhov no tso cai rau magnetic teb generated los ntawm cov dej ntws nyob rau hauv opposite lus qhia kom tshem tawm ib leeg tawm, yog li txo stray inductance. Qhov no yog qhov tseem ceeb tshwj xeeb rau cov tshuab siv siab -cov cuab yeej siv hluav taws xob ceev xws li IGBTs thiab SiC MOSFETs, vim nws txo qis qhov hluav taws xob zoo thaum hloov pauv thiab txhim kho cov cuab yeej kev ntseeg siab.

 

Hauv NEV sector, kev txhim kho txuas ntxiv ntawm siab -voltage platforms yuav tsum muaj cov khoom siv hluav taws xob sib txuas ua ke kom ua tau raws li qhov xav tau ntawm cov tam sim no siab - nqa lub peev xwm, lub teeb yuag, thiab qhov chaw optimization. Piv txwv li, Lub Hwj Chim Faib Fais Fab (PDU) busbar nyob rau hauv siab -voltage roj teeb systems yuav tsum tswj fais fab kev faib, kev tiv thaiv kev sib txuas, thiab txhim khu kev qha tam sim no conduction, muab siab dua xav tau ntawm cov khoom siv thiab cov qauv tsim.

 

Saib ua ntej, nrog rau kev txhim kho ntawm 800V thiab ntau dua voltage platforms, laminated busbars yuav ua lub luag haujlwm tseem ceeb hauv cov tshuab hluav taws xob tshiab.
 

 

Laminated busbars feem ntau muaj cov txheej txheem conductive, insulating txheej, thiab txheej tiv thaiv. Cov neeg siv hluav taws xob feem ntau yog ua los ntawm cov khoom siv tooj liab lossis txhuas, thaum cov ntaub ntawv insulating - xws li PET, PI, lossis epoxy resin- raug xaiv raws li qhov ntsuas hluav taws xob, qhov chaw thermal, thiab cov ntawv thov tshwj xeeb.

 

Cov txheej txheem tsim khoom feem ntau suav nrog precision stamping, khoov, kho qhov chaw, rwb thaiv tsev lamination, thiab qhov kawg lamination molding. Los ntawm kev tswj cov interlayer qhov sib nrug thiab qhov loj ntawm cov qauv, qhov qis -inductance thiab kev xa hluav taws xob muaj zog tuaj yeem ua tiav.

 

Hauv siab -kev hloov pauv hluav taws xob ceev, inductance ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hluav taws xob. Tshaj dhau lub voj inductance tuaj yeem ua rau muaj qhov hluav taws xob siab siab thaum lub sijhawm hloov pauv hloov pauv, cuam tshuam rau kev nyab xeeb ntawm cov khoom siv. Yog li ntawd, qis -inductance tsim yog ib qho tseem ceeb kev specification rau laminated busbars.

 

Rau siab -kev siv tsav ceev hauv kev lag luam automation, laminated busbars tsim rau kev sib txawv zaus drives (VFDs) optimize conductor layout kom txo tau lub voj voog tam sim no, yog li txhim kho kev ua hauj lwm ntawm qhov sib txawv zaus.

 

Ntxiv nrog rau kev txo qis inductance, laminated busbars muaj cov hauv qab no zoo:

 

Ua ntej, lawv txhim kho qhov chaw siv. Traditional wiring harnesses xav tau qhov chaw tseem ceeb, thaum lub laminated qauv integrates ntau yam conductive paths mus rau hauv ib tug compact hneev taw, tso cai rau ntau compact khoom designs.

 

Qhov thib ob, lawv txhim kho kev tswj xyuas thermal. Loj -surface- cheeb tsam tooj liab conductors txo lub zos tam sim no ceev thiab kub nce, txhim kho ntev - lub sij hawm ua hauj lwm stability.

 

Thib peb, lawv nce kev ntseeg tau ntawm kev sib dhos. Cov qauv kev sib xyaw ua ke txo qis tus naj npawb ntawm cov ntsiab lus sib txuas, txo qhov kev pheej hmoo ntawm kev ua tsis tiav los ntawm yam xws li xoob bolts lossis tiv tauj oxidation.

 

Hauv kev ua haujlwm siab - kev ua tau zoo suav, lub tshuab hluav taws xob yuav tsum txhawb nqa siab - nrawm, siab - kev xa khoom tam sim no; Yog li, laminated busbars tsim los rau supercomputer circuit boards lossis backplanes ua tau raws li qhov yuav tsum tau ua rau kev sib cog lus, muaj kev ntseeg siab heev hauv kev sib txuas ntawm cov servers thiab cov khoos phis tawj.

 

 

 

Tam sim no, qhov kev thov loj zuj zus rau cov laminated busbars feem ntau yog tsav los ntawm cov haujlwm xws li tsheb tshiab lub zog (NEVs), lub zog khaws cia, kev lag luam inverters, thiab cov chaw khaws ntaub ntawv.

 

Cov pob roj teeb, cov tswj lub cev muaj zog, thiab siab -voltage fais fab faib tshuab hauv NEVs txhua tus xav tau cov qauv xa hluav taws xob ruaj khov thiab txhim khu kev qha. Piv nrog rau cov kev sib txuas ntawm tooj liab ib txwm muaj, cov laminated busbars txo qhov hnyav thiab txhim kho qhov chaw siv thaum ua kom ntseeg tau tias kev ua haujlwm ruaj khov nyob rau hauv kev vibration -cov xwm txheej zoo ib yam ntawm lub tsheb ib puag ncig.

 

Hauv kev tswj lub cev muaj zog, lub cev muaj zog tswj lub cev muaj zog ua haujlwm siab - tam sim no kev sib txuas ntawm cov khoom siv hluav taws xob, yuav tsum muaj kev tiv thaiv tsawg, tsis tshua muaj inductance, thiab cua sov zoo heev. Raws li cov zis hluav taws xob ntawm NEVs nce, cov ntawv thov no tso cov kev xav tau ntxiv ntawm kev tsim busbar.

 

Kev loj hlob ntawm lub zog cia kev lag luam kuj tau tsav kev hloov kho thev naus laus zis rau laminated busbars. Loj - nplai lub zog cia tshuab- suav nrog cov roj teeb, cov khoom siv hluav taws xob hloov pauv, thiab cov tswj hwm- yuav tsum muaj cov qauv kev faib hluav taws xob muaj zog heev. Optimizing lub laminated tsim pab txo qhov system poob thiab txhim kho lub zog conversion efficiency.

 

Hauv kev lag luam kev sib txuas lus hauv kev lag luam, qhov kev xav tau ntawm 5G lub hauv paus chaw nres tsheb thiab cov cuab yeej siv hluav taws xob tau ua rau siab - cov qauv hluav taws xob ceev ceev yog qhov tseem ceeb. Laminated busbars tsim rau cellular chaw nres tsheb fais fab faib ua kom ruaj khov thiab compact zog layouts nyob rau hauv cov khoom siv sib txuas lus.

 

Lub caij no, cov chaw zov me nyuam tau teeb tsa cov kev xav tau tshiab rau siab - zog- qhov sib zog nqus hluav taws xob. Muab qhov chaw txwv nyob rau hauv cov neeg rau zaub mov racks, yuav tsum muaj cov kev daws teeb meem zoo, nyab xeeb, thiab txhim khu kev qha fais fab txuas. Yog li ntawd,laminated busbars rau khib-mount fais fab tuagtau nce los ua ib qho tseem ceeb ntawm cov ntaub ntawv niaj hnub chaw fais fab.
