Kev Ntsuam Xyuas Ntawm Cov Txheej Txheem Txheej Txheem Thiab Kev Siv Hluav Taws Xob Ntawm Laminated Tsawg -Inductance Busbars hauv Kev Tiv Thaiv Tsheb Tsheb Electromagnetic cuam tshuam

Raws li kev tsheb nqaj hlau thauj mus los thiab lub zog tshiab tsheb hloov mus rau lub zog siab dua thiab kev txawj ntse ntau dua, qib ntawm kev sib koom ua ke ntawm cov khoom siv hluav taws xob onboard tseem nce ntxiv. Lub siab - zaus hloov pauv thiab siab - tam sim no kev hloov pauv hloov pauv yam ntxwv ntawm traction converters ua kom muaj kev sib txuas siab siab - zaus hluav taws xob hluav taws xob hluav taws xob thiab kev cuam tshuam kev sib raug zoo, cuam tshuam ncaj qha rau kev ua haujlwm ruaj khov ntawm lub tsheb teeb liab thiab precision sensors. Thaum siv nyob rau hauv siab - fais fab converters, laminated busbars -nrog lawv cov tshwj xeeb low-inductance architecture- txwv electromagnetic cuam tshuam ntawm qhov chaw; lawv tshem tawm cov kev tsis zoo ntawm cov tsoos tooj liab busbar layouts -xws li chaotic thaiv, siab voj inductance, thiab tsis zoo magnetic teb tshem tawm- yog li ua kom muaj hluav taws xob huv rau lub tsheb.

Lub hauv paus ua rau nquag electromagnetic cuam tshuam (EMI) nyob rau hauv automotive systems yog nyob rau hauv ib txwm conductive kev twb kev txuas txoj kev, uas feature lub voj loj cheeb tsam thiab siab parasitic inductance, ua rau lawv nquag tsim hluav taws xob hluav taws xob hnyav nyob rau hauv siab - zaus khiav hauj lwm tej yam kev mob. Qhov no tsis yog tsuas yog ua rau qhov hluav taws xob nce siab thiab cov cuab yeej oscillation- ua rau muaj cua sov- tab sis kuj cuam tshuam cov teeb liab kis raug. Laminated busbars zoo daws qhov teeb meem no; lawv cov kev tsim tshwj xeeb, uas muaj qhov sib tw nruj thiab sib npaug - teeb tsa qhov zoo thiab qhov tsis zoo, tso cai rau cov chaw sib nqus uas tsim los ntawm kev tawm tsam tam sim no tshem tawm ib leeg tawm ntawm thaj chaw loj. Qhov no drastic txo qhov zoo tam sim no voj cheeb tsam thiab suppresses parasitic inductance mus rau qib qis heev.

Nyob rau hauv siab - zaus zaus, lub voj inductance yog thawj tus tsav tsheb ntawm EMI thiab voltage spikes. Muab piv rau cov kev sib txuas ib txwm siv- uas feem ntau pom qhov muaj txiaj ntsig siab inductance nyob rau ntau pua nanohenries (nH)-laminated busbars txo qis inductance, ua rau muaj txiaj ntsig zoo tiv thaiv qhov hluav taws xob thiab cov oscillations tam sim no tshwm sim los ntawm siab - zaus IGBT hloov. Qhov qis - tus yam ntxwv inductance no tsis tsuas yog txo cov suab nrov ntawm hluav taws xob thiab txo cov hluav taws xob hluav taws xob sab nraud tab sis kuj tseem tiv thaiv cov khoom siv hluav taws xob tseem ceeb los ntawm kev hloov pauv siab -voltage surges, yog li txhim kho tag nrho cov kab ke kev nyab xeeb.

Txhawm rau tshem tawm electromagnetic crosstalk, laminated busbars siv lub modular, integrated layout characterized by orderly routing, clear zoning, and the absence of suspended or crossing tracts. Qhov kev tsim no yog qhov tseem ceeb tshwj xeeb rau kev thov kev siv xws li siab-voltage, tawg- pov thawj inverter busbars; Nws ua tau zoo txo ​​qis kev sib txuas ntawm kev sib txuas ntawm cov voj voog thiab thaiv cov kab sib txuas ntawm cov siab - zog thiab qis - fais fab circuits. Los ntawm kev tiv thaiv lub zog hluav taws xob los ntawm kev cuam tshuam nrog kev tswj xyuas qhov tseeb thiab cov teeb liab circuits, nws txhim kho lub tsheb lub tshuab hluav taws xob sib raug zoo (EMC) thiab ua kom muaj kev ruaj ntseg ntawm ntau yam khoom siv hluav taws xob.

Laminated busbars feem ntau muaj kev sib koom ua ke, tag nrho cov txheej txheem rwb thaiv tsev uas muaj kev sib cais hluav taws xob zoo, cuam tshuam cov hluav taws xob tsis zoo thiab tam sim no crosstalk thaum txo qis kev sib haum xeeb. Cov busbars muaj cov yam ntxwv ruaj khov electromagnetic nyob rau hauv kev ua haujlwm tsis zoo-xws li acceleration, deceleration, sudden load hloov, thiab nquag pib-stop cycles-tiv thaiv teeb meem xws li surges nyob rau hauv electromagnetic suab nrov thiab parameter drift, yog li xyuas kom meej lub lag luam thiab lub sij hawm ntawm lub tsheb precision.

Hais txog cov qauv ntawm lub cev, lub laminated busbar yog qhov tseem ceeb ntawm ntau- txheej sib txuas bar tsim los ntawm cov txheej txheem laminating cov neeg xyuas pib thiab cov ntaub ntawv insulating nyob rau hauv qhov kub thiab txias, tsim kom muaj qhov tsawg -impedance, txhim khu kev qha tam sim no kis tau tus mob nyob rau hauv ib tug compact qhov chaw. Qhov kev tsim no tsis tsuas yog optimizes hluav taws xob kev ua tau zoo tab sis kuj tswj cov neeg kho tshuab stability; cov ntaub ntawv insulating ntawm tus neeg xyuas pib txheej muab cov khoom siv hluav taws xob tiv thaiv hluav taws xob, ua kom muaj kev ruaj ntseg ntawm cov teeb liab thiab lub zog xa mus.

Hauv cov haujlwm uas yuav tsum muaj kev nyab xeeb nruj, xws li kev tsheb ciav hlau, laminated busbars ua raws li cov qauv kev sib raug zoo ntawm electromagnetic compatibility (EMC). Lawv txwv kev cuam tshuam ntawm electromagnetic cuam tshuam los ntawm cov cuab yeej siv nws tus kheej thaum txhim kho lub cev tag nrho kev tiv thaiv kev cuam tshuam, daws cov teeb meem kev lag luam zoo xws li teeb liab hloov pauv, yuam kev yuam kev tshwm sim, thiab qhov ua tsis tiav. Tsis tas li ntawd, lawv cov txheej txheem kev teeb tsa txo cov naj npawb ntawm cov ntsiab lus sib txuas piv rau cov txheej txheem kev sib txuas ib txwm muaj, txhim kho qhov kev vibration tsis kam ntawm cov qauv tsim.

Rau siab -lub zog hluav taws xob hluav taws xob tshuab hluav taws xob, qis-inductance laminated busbars ua tiav qhov kev sib tw ntau dua thiab ntau qhov kev sib cog lus los ntawm kev tsim tus neeg xyuas kom zoo. Hauv IGBT lub cev muaj zog tsav, qhov qis - inductance qauv no ua rau cov cuab yeej siv hluav taws xob ua haujlwm ruaj khov ntawm kev hloov pauv ntau dua, yog li txo qhov loj ntawm cov lim dej thiab cov khoom sib nqus, txo qhov kev poob qis, thiab txhawb nqa tag nrho kev ua haujlwm kom tau raws li qhov xav tau ntawm cov khoom siv niaj hnub no, siab - zog- ntom ntom.

Hauv cov ntawv thov kev tsim vaj tsev, tus naj npawb ntawm cov txheej txheem txheej txheem thiab cov txheej txheem teeb tsa ntawm cov laminated busbars rau IGBTs tuaj yeem raug kho raws li cov yam ntxwv xws li tam sim no - nqa peev xwm, ntsuas kub nce, thiab kev txwv spatial. Cov txheej txheem ntau- txheej nyias- tooj liab ua kom lub tshav kub dissipation cheeb tsam thiab ua kom luv thermal conduction txoj kev, ua kom yooj yim dua cov cua kub dissipation. Qhov no optimized thermal tswj tsim tsis tsuas yog txo qhov tshwm sim ntawm qhov chaw kub ntawm lub zos tab sis kuj zoo txo ​​qhov kub thiab txias thaum lub sij hawm ua hauj lwm, li no pab txhawb lub zuag qhia tag nrho kev cia siab ntawm cov khoom.
