Kev Tshawb Fawb Txog Kev Ntsuas Tus Kheej Thiab Kev Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob Cov Hluav Taws Xob hauv Hluav Taws Xob Hluav Taws Xob

Hauv cov tshuab hluav taws xob niaj hnub siv hluav taws xob, cov khoom siv hluav taws xob ua haujlwm ua cov khoom tseem ceeb rau lub zog buffering thiab kev tswj fais fab thoob plaws ntau lub converters thiab lub zog cia. Tshwj xeeb tshaj yog nyob rau hauv architectures uas muaj hluav taws xob tsheb (EV) busbars thiab lub hwj chim capacitor busbars, lawv lub luag hauj lwm txuas ntxiv tshaj li kev lim dej thiab lub zog cia kom muaj kev cuam tshuam ncaj qha rau kev ua haujlwm thiab kev ntseeg tau. Tsav los ntawm kev hloov pauv mus rau lub zog siab dua thiab kev ua haujlwm ntau dua, cov co-tsim qauv ntawm cov capacitors thiab cov qauv busbar tau dhau los ua qhov tseem ceeb; Kev tswj cov kab hluav taws xob thiab cov kab mob parasitic nyob rau hauv lub system tam sim no yog ib qho tseem ceeb tsim metric.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Hais txog kev xaiv capacitor, engineers feem ntau ntsib kev lag luam - tawm ntawm electrolytic thiab film capacitors. Cov txheej txheem tsim ntawm lub capacitor busbar thiab cov rwb thaiv tsev ntawm cov ntaub ntawv busbar ncaj qha cuam tshuam rau tag nrho cov kab hluav taws xob kev nyab xeeb thiab thermal stability. Thaum electrolytic capacitors muab ntau dua volumetric zog ceev, zaj duab xis capacitors ua tau zoo nyob rau hauv tuav siab - zaus ripple tam sim no thiab tuav ntev - lub sij hawm stability, yuav tsum tau daim ntawv thov - tshwj xeeb xaiv.

 

Los ntawm qhov kev xav ntawm lub hwj chim hluav taws xob topologies, IGBT busbars thiab EV laminated busbars feem ntau tsim cov tub ntxhais txoj kev tam sim no hauv siab - zaus hloov tshuab; Lub peev xwm los tswj cov kab mob parasitic inductance nyob rau hauv cov khoom no ncaj qha cuam tshuam rau kev hloov pauv thiab kev tawm tsam ntawm qhov hluav taws xob spikes. Tsis tas li ntawd, txoj kev sib txuas ntawm busbar thiab DC -link capacitor- xws li cov kev teeb tsa tshwj xeeb rau DC - txuas capacitor- txiav txim siab lub tsheb npav DC ripple cov yam ntxwv thiab kev muaj peev xwm teb tau ntev.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Zaj duab xis capacitors feem ntau siv cov qauv ua yeeb yaj kiab polypropylene metallized, uas ua rau nws tus kheej zoo heev - kho cov khoom hauv siab - zaus, siab -voltage ib puag ncig. Hauv kev tsim kho vaj tse, EV zaj duab xis capacitor busbars thiab insulated busbars rau EV capacitors nquag ua haujlwm hauv cov tshuab hluav taws xob tshiab los txhim kho kev ruaj ntseg nyob rau hauv siab dv / dt (hloov voltage hloov ceev) cov xwm txheej. Tsis tas li ntawd, insulated tooj liab busbars tau dav siv nyob rau hauv EV powertrains kom muaj kev nyab xeeb kev sib cais thiab ua tau zoo tam sim no conduction thaum lub sij hawm siab - kis tau tus mob tam sim no.

 

Hais txog kev tso tawm ib nrab thiab kev tsim rwb thaiv tsev, cov tshuab capacitor feem ntau xav tau kev ua kom zoo dua los ntawm cov qauv ntim khoom zoo heev. Piv txwv li, kev tsim qauv ntawm EV roj teeb busbars thiab busbars rau zaj duab xis capacitors tuaj yeem txo cov hluav taws xob hauv hluav taws xob hauv siab -voltage DC ib puag ncig, yog li txuas ntxiv lub neej tag nrho thiab kev ntseeg tau.

 

Hauv kev hloov hluav taws xob thiab kev siv hluav taws xob cia, EV capacitor connector bars thiab fais fab faib hluav taws xob feem ntau yog siv los tsim kom muaj tsawg- impedance kev sib txuas ntawm capacitor modules, thaum tooj liab busbars rau automotive fais fab tshuab muab kev ruaj ntseg conductive rau siab - tam sim no kis tau tus mob, kom ntseeg tau tias kev lag luam txhim khu kev qha ntawm lub hwj chim modules nyob rau hauv hnyav loads.

 

Nyob rau hauv lub architectures ntawm lub zog tshiab tsheb thiab siab -voltage DC systems, tsheb busbars ua hauj lwm raws li ib qho tseem ceeb conductive ntsiab; ua ke nrog cov kev cai busbars tsim los rau kev faib hluav taws xob zoo, lawv tsim cov kev faib hluav taws xob hloov tau yooj yim. Tsis tas li ntawd, customized conductive tooj liab busbars optimize txoj kev tam sim no faib los ntawm cov qauv tsim, yog li txo tag nrho cov kev poob.

 

Hais txog kev tsim cov txheej txheem thiab cov khoom siv, cov tin-plated tooj liab busbars rau EVs siv cov kev kho saum npoo los txhim kho oxidation tsis kam thiab kev ntseeg siab, ua kom lawv ua tau raws li qhov xav tau ntawm kev ua haujlwm ntev - lub sijhawm ua haujlwm nyob rau hauv cov xwm txheej nyuaj. Xws li cov khoom tseem ceeb heev rau siab - kev ntseeg tau lub zog modules.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Nyob rau theem kev sib koom ua ke, busbar systems nyob rau hauv lub tsheb fais fab siab -voltage platforms yuav tsum muaj ntau txoj hauv kev- ntsuas kev tswj thermal, electromagnetic compatibility, thiab mechanical structural integrity- kom ntseeg tau tias kev ua haujlwm ruaj khov thaum muaj kev hloov pauv hloov pauv.

Hauv cov ntsiab lus, kev sib koom ua ke ntawm cov yeeb yaj kiab capacitors thiab busbar systems tau dhau los ua qhov tseem ceeb hauv kev ua kom zoo ntawm cov khoom siv hluav taws xob niaj hnub no.

 

Los ntawm kev teeb tsa cov qauv siv hluav taws xob thiab cov capacitor topologies,Automotive BusBar PET rwb thaiv tsevua rau nws muaj peev xwm txo tau qhov system poob thaum ib txhij txhim kho lub zog ceev thiab kev ntseeg tau, yog li muab kev txhawb nqa tseem ceeb rau kev txhim kho yav tom ntej ntawm siab -voltage, high- zaus fais fab hluav taws xob tshuab hluav taws xob.
