EV Film Capacitor Busbar Integrated Component Technology Analysis

Hauv kev tsav hluav taws xob thiab kev tswj hwm ntawm cov tsheb tshiab lub zog, DC qhov kev tswj hwm qhov hluav taws xob thiab cov theem tsis ncaj ncaj txiav txim siab qhov kev ruaj ntseg ntawm lub zog tso zis. EV Film Capacitor Busbar yog ib qho tseem ceeb sib xyaw ua ke ntawm lub cev muaj zog ntawm lub cev muaj zog, kev sib koom ua ke ntawm zaj duab xis capacitor thiab ib qho kev txiav txim siab los muab DC -Txuas kev txhawb nqa, stabilizing lub inverter input voltage thiab absorbing siab - zaus pulse tam sim no. Cov khoom no yog lub luag haujlwm rau kev lim dej thiab tswj cov DC lub zog los ntawm cov roj teeb hluav taws xob, muab cov khoom siv hluav taws xob xws li IGBTs thiab SiC MOSFETs kom tiav AC-DC hloov dua siab tshiab thiab tsav lub tsheb lub cev muaj zog. Nws yog ib qho tseem ceeb hub nyob rau hauv lub siab -voltage hluav taws xob tsav system, thiab kev lag luam feem ntau siv lub Busbar rau DC-Txuas Capacitor integrated tov nyob rau hauv loj ntau lawm.

Tag nrho cov kev sib xyaw ua ke muaj ob lub hauv paus tseem ceeb, uas ua haujlwm ua ke kom tau raws li qhov siab -voltage, siab- zaus ua haujlwm ntawm cov ntawv thov tsheb. Nyias- zaj duab xis capacitors, raws li lub hauv paus ntsiab lus rau lub zog cia thiab kev tswj qhov hluav taws xob, muab cov txiaj ntsig zoo tshaj plaws ntawm cov khoom siv hluav taws xob aluminium electrolytic capacitors, suav nrog qis siab -voltage resistance, qis sib npaug series poob thiab inductance, tsis yog -polarity, nws tus kheej- kho lub neej ntev, thiab kev ua haujlwm ntev dua. Lawv tau sib xws nrog tam sim no mainstream 800V siab-voltage automotive platforms, tshem tawm qhov xav tau ntau lub capacitors hauv series kom phim siab-voltage circuit designs, yooj yim rau kev teeb tsa hluav taws xob hauv hluav taws xob, thiab ib txhij txhim kho lub sijhawm ntev - kev cia siab. Multilayer busbar yog ib tug precision{13}}machined hlau conductive tivthaiv ua los ntawm tooj liab los yog txhuas substrate. Nws cov txheej txheem ntau- txheej sib txuas ua ke txo cov kab mob parasitic inductance nyob rau hauv Circuit Court, zoo suppressing voltage spikes generated thaum lub sij hawm siab - zaus hloov ntawm cov khoom siv fais fab, txo cov kev pheej hmoo ntawm cov cuab yeej tawg. Qhov qis-inductance qauv no kuj yog ib qho tseem ceeb ntawm cov qauv tsim ntawm EV Laminated Busbars khoom.

Los ntawm kev xav txog kev ua haujlwm engineering, kev sib koom ua ke busbar sib dhos ntawm nyias - zaj duab xis capacitors rau lub tsheb fais fab muaj peb lub luag haujlwm tseem ceeb hauv hluav taws xob tsis tuaj yeem hloov tau. Ua ntej, nws muab kev tswj xyuas qhov hluav taws xob thiab kev lim dej, nqus cov kev hloov pauv ntawm qhov hluav taws xob thiab cov ripple tam sim no tsim nyob rau hauv DC Circuit Court thaum lub sijhawm ua haujlwm inverter, tso tawm qhov hluav taws xob DC tsis tu ncua rau cov khoom siv hluav taws xob, thiab tiv thaiv kev puas tsuaj los ntawm qhov hluav taws xob tam sim no -voltage spikes. Secondly, nws muab dynamic zog buffering; Thaum lub sij hawm acceleration thiab regenerative braking, lub Circuit Court tam sim no fluctuates heev, thiab nyias - zaj duab xis capacitor tuaj yeem ua kom tiav kev them nyiaj sai thiab tawm, smoothing instantaneous zog fluctuations thiab xyuas kom meej lub cev muaj zog zog tso zis. Thib peb, nws tiv thaiv cov khoom siv hluav taws xob, nqus siab - zaus ripple tsim los ntawm kev hloov pauv kev ua haujlwm raws li nws cov yam ntxwv qis sib npaug sib npaug, txo qis kev hloov pauv ntawm IGBTs thiab silicon carbide cov cuab yeej, txo qis kev ntxhov siab, ncua lub neej ntawm lub zog semiconductors, thiab yoog mus rau siab - thauj khoom tsis tu ncua hauv tsheb.

Raws li lub zog tshiab hluav taws xob tsav tsheb rov qab mus rau lub zog ntau dua, kev ua haujlwm me me, thiab kev sib koom ua ke siab, cov txheej txheem thiab cov qauv tsim ntawm nyias -film capacitor busbar integrated Cheebtsam kuj tau tsim ib qho kev qhia meej txog kev hloov pauv. Cov qauv kev sib xyaw ua ke ntawm cov khoom siv hluav taws xob thiab cov kab ntau txheej tuaj yeem txo qhov siab - zaus parasitic inductance los ntawm ze li 20%, thaum tseem txo cov txheej txheem sib dhos sab hauv hauv kev tswj hluav taws xob, yog li compressing tag nrho cov khoom siv thiab cov nqi sib dhos. Targeting lub siab - zaus khiav hauj lwm yam ntxwv ntawm silicon carbide li, tus tsim ntawm kev txhawb nqa nyias- zaj duab xis capacitors yog tsis tu ncua optimized, iterating thiab upgrading rau qis sib npaug series inductance, ib tug kub kuj ntau yam ntawm 135 degree, thiab miniaturization thiab lub teeb yuag tsim. Ua ke nrog cov txheej txheem rwb thaiv tsev, EV Film Capacitor Busbar yog tsim los ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hluav taws xob txuas ntxiv.
