Yuav Ua Li Cas Ntsuas Tus Nqi, Stray Inductance, thiab Voltage Withstand Capability hauv Laminated BusBars? Phau Ntawv Qhia Kev Xaiv Engineering

Thaum xaiv Laminated BusBars, ib qho yuav tsum tsis txhob tsom mus rau kev ua tiav tus nqi qis tshaj, yam tsawg kawg nkaus inductance, lossis qhov ntsuas qhov siab tshaj plaws; Hloov chaw, ib qho qauv tsim nyog yuav tsum tau txiav txim siab los ntawm kev txiav txim siab qhov kev ua haujlwm voltage, tam sim no, hloov zaus, qhov chaw teeb tsa, thiab cov kev xav tau rwb thaiv tsev. Rau IGBT inverters, lub zog cia PCS units, thiab siab - lub zog hluav taws xob cov khoom siv hluav taws xob, lub qhov dej zoo - tsim laminated busbar sib npaug qhov xav tau kom ua tau raws li cov khoom siv hluav taws xob nrog kev tswj cov khoom siv thiab cov nqi tsim khoom.

 

 

Ua ntej, tus neeg xyuas pib tus ntoo khaub lig- ntu ntu thiab tuab yuav tsum tau txiav txim siab raws li qhov tam sim no tsis tu ncua, qhov siab tshaj plaws tam sim no, thiab qhov tso cai kub nce. Thaum nce tus ntoo khaub lig- ntu ntu yog ib txoj hauv kev los txhim kho tam sim no - nqa lub peev xwm ntawm laminated tooj liab busbars, tsuas yog nce thickness tsis yog ib txwm zoo; Kev siv cov khoom siv ntau ntxiv ntxiv qhov hnyav thiab tus nqi thaum ua rau kev tsim khoom nyuaj, yog li tus qauv tsim yuav tsum tau ua kom haum rau qhov kev xav tau tiag tiag.

 

Rau siab -kev hloov cov khoom siv ceev xws li IGBTs thiab SiC cov khoom, qhov chaw voj tam sim no cuam tshuam ncaj qha rau cov inductance. Laminated busbars tsim los rau IGBT-raws li lub cev muaj zog ua rau txo qis cov kab mob parasitic los ntawm kev txo txoj hauv kev tam sim no ntawm qhov zoo thiab qhov tsis zoo thiab ua kom zoo dua interlayer sib nrug, yog li txo qhov voltage spikes thiab EMI teeb meem thaum lub sij hawm siab - hloov ceev.

 

Voltage withstand yuav tsum dictate lub rwb thaiv tsev qauv. Cov kev daws teeb meem rwb thaiv tsev-xws li Varnished Insulated Busbars (VIB)- yuav tsum tau xaiv raws li yam xws li ntsuas qhov ntsuas hluav taws xob, rwb thaiv tsev thickness, creepage nrug, hluav taws xob clearance, thiab kev khiav hauj lwm kub. Rau siab- cov ntawv siv hluav taws xob, txoj hauv kev muaj ntau dua li kev nce rwb thaiv tsev tuab; ib qho yuav tsum xav txog tag nrho cov qauv qhov ntev thiab qhov tseeb ntawm qhov chaw teeb tsa.

 

 

Hauv kev yuav khoom tiag tiag, nws raug nquahu kom ua raws li kev tsim qauv ntawm lub hauv paus ntsiab lus ntawm "kev sib ntsib specifications es tsis ua raws li qhov siab tshaj plaws." Kev tsim ntawm laminated busbars suav nrog kev ntsuas ntau yam:

 

• Tus nqi - qhov tseem ceeb:Siv cov txheej txheem ntawm cov txheej txheem thiab cov thicknesses tsim nyog uas ua tau raws li qhov tam sim no thiab qhov hluav taws xob tiv taus, yog li txo qis kev siv cov khoom siv tsis tsim nyog thiab cov txheej txheem ua tiav.

 

• Tsawg- qhov tseem ceeb ntawm inductance:Txo qhov kev ncua deb ntawm qhov zoo thiab tsis zoo terminals thiab txo cov voj voog tam sim no; txoj hauv kev no yog tsim rau siab -ceev IGBT thiab SiC fais fab modules.

 

• Voltage- tiv taus qhov tseem ceeb:Xaiv cov ntaub ntawv rwb thaiv tsev thiab thicknesses raws li qhov system voltage thaum tswj nruj nreem creepage nrug thiab hluav taws xob clearances.

 

• Qhov chaw - qhov tseem ceeb:Rau cov khoom siv compact, ntiav ntau- txheej txheej kom ua tiav qhov kev faib tawm tam sim no hauv qhov chaw teeb tsa tsawg.

 

Yog li ntawd, qhov zoo tshaj plaws tsim rau laminated busbars txuas IGBTs thiab lub tsev txhab nyiaj capacitor tsis tas yuav yog tus nqi qis tshaj lossis kev ua haujlwm siab tshaj; es, nws yog qhov kev daws teeb meem uas txo qis cov khoom siv tsis tsim nyog thiab cov txheej txheem tsim khoom thaum ua kom txaus siab rau cov kev xav tau tam sim no, tsis muaj zog inductance, thiab rwb thaiv tsev.

 

Yuav tsum sib npaug tus nqi busbar, stray inductance, thiab voltage tiv taus?

 

Thov Laminated Busbar Design Review

 

Cov ntaub ntawv yog ib feem tseem ceeb ntawm cov nqi. Thaum tooj liab busbars rau lwm qhov kev siv hluav taws xob muaj hluav taws xob zoo, lwm yam khoom siv hluav taws xob tuaj yeem raug soj ntsuam raws li cov kev cai tam sim no thiab cov qauv siv rau cov ntawv siv qhov hnyav thiab tus nqi yog qhov tseem ceeb.

 

Tus neeg xyuas pib thickness kuj ncaj qha cuam tshuam cov khoom siv thiab cov nqi ua haujlwm. Rau laminated busbars siv nrog siab -tam sim no IGBT Circuit Court boards, thickness yuav tsum tau txiav txim raws li qhov tseeb tam sim no, kub nce, thiab installation qhov chaw txwv, es tsis tsuas yog nce tus ntoo khaub lig-sectional cheeb tsam.

 

Cov ntaub ntawv rwb thaiv tsev kuj cuam tshuam cov nqi khoom thiab qhov ntev. Cov ntawv thov xws li laminated busbars rau DC kev them nyiaj yug capacitors (siv polypropylene zaj duab xis dielectrics) yuav tsum xaiv cov txheej txheem rwb thaiv tsev tsim nyog raws li qhov ntsuas hluav taws xob, qhov kub thiab txias, thiab cov txheej txheem interlayer kom tsis txhob dhau - engineering.

 

Cov txheej txheem tsim khoom txiav txim siab tus nqi ntawm kev tsim cov txheej txheem nyuaj. Laminated busbars rau PV inverters yuav koom nrog ntau cov kauj ruam- xws li stamping, CNC machining, vuam, thiab lamination; Yog li ntawd, txo qis qhov tsis tsim nyog, khoov, thiab cov pob qij txha welded thaum lub sij hawm tsim pab txo cov nqi tsim khoom thiab txhim kho cov khoom sib xws.

 

 

Thaum muab cov khoom siv hluav taws xob rau hluav taws xob hluav taws xob, cov kws tshaj lij yuav tsum tau saib dhau qhov tsuas yog cov nqi sib tw nqi thiab xyuas seb tus neeg muag khoom puas tuaj yeem koom nrog hauv- kev ntsuam xyuas hauv theem pib. Cov neeg tsim khoom tsim muaj peev xwm tsim tau (DFM) tuaj yeem txheeb xyuas cov teeb meem ntawm cov qauv thiab kev tsim khoom thaum ntxov los ntawm kev tshuaj xyuas 2D / 3D kos duab, cov lus qhia tam sim no thiab voltage, thiab qhov chaw teeb tsa.

 

Kev tsim khoom muaj peev xwm tseem cuam tshuam ncaj qha rau cov txiaj ntsig xa khoom zaum kawg. Kev tsim cov laminated busbars rau lub cev muaj zog thiab lub zog hluav taws xob feem ntau muaj cov txheej txheem xws li precision stamping, CNC machining, rwb thaiv tsev lamination, thiab laser los yog tsis kam vuam; tus neeg muag khoom cov cuab yeej tsim khoom thiab cov txheej txheem tswj kev muaj peev xwm yog qhov tseem ceeb hauv kev txiav txim siab cov khoom sib xws.

 

Cov txheej txheem tswj kev ua tau zoo yuav tsum suav nrog cov khoom siv, qhov ntev, kev ua haujlwm hluav taws xob, thiab batch traceability. Rau laminated busbars siv nyob rau hauv lub hwj chim capacitor DC txuas, cov chaw tseem ceeb los xyuas thaum lub sij hawm yuav khoom muaj xws li kev soj ntsuam cov khoom, seem checks, rwb thaiv tsev tiv thaiv voltage xeem, weld sib koom soj ntsuam, thiab ua raws li cov qauv kev tswj zoo xws li ISO 9001 thiab IATF 16949.
