Yuav Ua Li Cas Xaiv Lub Chaw Tsim Tshuaj Laminated Busbar: Tsim Daim Ntawv Qhia rau Tsawg -Inductance Busbars rau Tshiab Zog Tsheb Inverters thiab Zog Cia Systems

SiC MOSFET thiab IGBT modules siv nyob rau hauv lub zog tshiab tsheb (NEV) inverters, lub zog cia PCS units, thiab photovoltaic inverters tau hloov mus rau ntau zaus thiab ntau zog zog. Ib txwm ib txwm - txheej busbars, vim lawv qhov chaw loj tam sim no, tsim cov kab mob parasitic inductance, uas tuaj yeem ua rau muaj hluav taws xob overshoot thiab EMI teeb meem thaum lub sij hawm siab - hloov ceev.

 

Tshwj xeeb tsim Laminated Busbar siv nruj nreem txheej zoo thiab tsis zoo tooj liab txheej los tsim ib tug sib nqus teb tshem tawm cov nyhuv ntawm tawm tsam tam sim no. Qhov kev tsim no ua kom tsis muaj zog inductance qis dua 10 nH, txo qis kev ntxhov siab ntawm cov khoom siv hluav taws xob thiab txhim kho kev ntseeg tau.

 

Rau NEV Tier 1 thiab Tier 2 cov chaw muag khoom, cov chaw tsim khoom roj teeb, thiab cov khoom siv hluav taws xob hluav taws xob tsim hluav taws xob, xaiv cov khoom siv laminated busbar yuav tsum saib tshaj tus nqi; Nws yog ib qho tseem ceeb rau kev soj ntsuam tus neeg muag khoom lub peev xwm hauv kev ua tooj liab, rwb thaiv tsev lamination, vuam thiab kev sib dhos, kev tswj qhov ntev, thiab kev tswj xyuas tsheb zoo.

 

 

1. Kev tswj ntawm stray inductance txiav txim siab lub zog module kev ntseeg tau

 

SiC MOSFET thiab IGBT modules muaj qhov siab - nrawm hloov peev xwm. Raws li tus nqi ntawm kev hloov pauv tam sim no (di / dt) nce, cov kab mob parasitic inductance nyob rau hauv cov qauv kev sib txuas ua kom muaj qhov hluav taws xob txhais los ntawm:

 

V=L × di/dt

 

Yog li ntawd, txawm hais tias lub hwj chim module nws tus kheej ua tau raws li qhov yuav tsum tau muaj qhov ntsuas hluav taws xob, lub busbar tsim tsis zoo tuaj yeem ua rau cov hluav taws xob tsis zoo uas ua rau:

• Overvoltage ntawm cov khoom siv fais fab;
• Kev hloov pauv ntau ntxiv;
• Nce EMI;
• Txo cov semiconductor lifespan.

 

Tsawg-inductance laminated busbar tsim feem ntau yuav tsum tau ua raws li cov cai hauv qab no:

2. Magnetic teb tshem tawm qauv ua rau qis -inductance kev ua tau zoo

 

Lub hauv paus ntsiab lus tseem ceeb tom qab inductance txo nyob rau hauv laminated busbars yog shortening tam sim no voj nrug ntawm qhov zoo thiab tsis zoo terminals.

 

Traditional tooj liab busbars:

• Loj nyob deb ntawm qhov zoo thiab tsis zoo terminals;
• Sib nqus teb tsis tuaj yeem tshem tawm ib leeg tawm;
• High parasitic inductance.

 

Laminated busbars:

• DC + thiab DC - terminals yog nyob ze;
• Tam sim no ntws nyob rau hauv opposite lus qhia;
• Sib nqus teb tshem tawm ib leeg tawm;
• Loop cheeb tsam raug txo.

 

Cov qauv tsim tseem ceeb cuam tshuam rau kev ua haujlwm inductor:

 

Yog li ntawd, ib tug tsim nyog laminated busbar chaw tsim tshuaj paus yuav tsum tsis tau tsuas yog tsim muaj peev xwm, tab sis kuj muaj kev txawj ntse nyob rau hauv electromagnetic tsom xam thiab cov qauv optimization.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Hu rau tam sim no

 

Qhia koj cov duab kos duab kos duab, qhov xav tau voltage / tam sim no, lossis cov ntaub ntawv thov rau kev tawm tswv yim engineering.

 

Lub sijhawm ntev - kev cia siab rau kev ua haujlwm ntawm laminated busbars feem ntau nyob ntawm cov ntaub ntawv rwb thaiv tsev.

 

Cov txheej txheej rwb thaiv tsev yuav tsum tau ua raws li cov cai hauv qab no:

• High dielectric zog;
• Tsawg noo noo nqus;
• Siab -kub stability;
• Thermal cycling kev ntseeg tau;
• Zoo interlaminar adhesion.

 

Cov khoom ntawm cov khoom siv:

 

Hauv kev siv lub zog tshiab tsheb, lub rwb thaiv tsev thickness yuav tsum muaj qhov sib npaug ntawm:

• kev nyab xeeb clearance;
• stray inductance;
• Thaum tshav kub kub dissipation muaj peev xwm.

 

Tshaj rwb thaiv tsev thickness:

→ nce qhov kev ncua deb ntawm qhov zoo thiab tsis zoo terminals
→ nce parasitic inductance

 

Tsis txaus rwb thaiv tsev thickness:

→ txo voltage withstand peev
→ ua rau muaj kev pheej hmoo ntawm kev tso tawm ib nrab

 

Yog li ntawd, kev cai laminated busbar tej yaam num yuav tsum tau xaiv cov khoom raws li qhov tshwj xeeb voltage ntsuas, tam sim no, thiab kev khiav hauj lwm ib puag ncig.

 

 

Ntau qhov haujlwm busbar dhau qhov kev sim thawj zaug tab sis pom cov teeb meem hauv qab no tom qab kev caij tsheb kauj vab ntev ntev:
