Thaum tham txog kev tsim kho tshiab thiab kev txhim kho hauv cov tshuab hluav taws xob ntawm cov tsheb fais fab, feem ntau qhov kev tsom mus rau cov khoom tseem ceeb xws li chav tswj hwm tseem ceeb thiab cov khoom siv fais fab, thaum cov khoom pabcuam xws li capacitors feem ntau tau txais kev saib xyuas tsawg dua. Txawm li cas los xij, cov khoom pabcuam no muaj kev cuam tshuam loj rau kev ua haujlwm tag nrho ntawm lub kaw lus. Tsab xov xwm no yuav nkag mus rau hauv kev siv YMIN zaj duab xis capacitors hauv onboard chargers thiab tshawb nrhiav kev xaiv thiab kev siv capacitors hauv cov tsheb fais fab.

Ntawm ntau hom capacitors,cov khoom siv hluav taws xob aluminium electrolytic capacitorsmuaj keeb kwm ntev thiab tau nyob hauv txoj haujlwm tseem ceeb hauv kev siv hluav taws xob fais fab. Txawm li cas los xij, nrog rau kev hloov pauv ntawm cov kev xav tau thev naus laus zis, cov kev txwv ntawm cov electrolytic capacitors tau pom tseeb dua. Yog li ntawd, lwm txoj hauv kev zoo dua - cov yeeb yaj kiab capacitors - tau tshwm sim.

Piv rau cov electrolytic capacitors, cov film capacitors muaj cov txiaj ntsig zoo ntawm kev ua haujlwm ntev ntawm lub zog hluav taws xob, kev tiv thaiv qis sib npaug (ESR), tsis muaj polarity, ruaj khov, thiab lub neej ntev. Cov yam ntxwv no ua rau cov film capacitors zoo tshaj plaws hauv kev yooj yim tsim qauv, txhim kho lub peev xwm tam sim no, thiab muab kev ua tau zoo dua nyob rau hauv cov xwm txheej ib puag ncig hnyav.

Rooj: Cov txiaj ntsig kev ua tau zoo sib piv ntawmcov capacitors zaj duab xisthiab cov khoom siv electrolytic aluminium

Los ntawm kev sib piv cov kev ua tau zoo ntawm cov zaj duab xis capacitors nrog rau qhov chaw siv hluav taws xob ntawm cov tsheb fais fab, nws pom tseeb tias muaj qib siab ntawm kev sib raug zoo ntawm ob qho tib si. Yog li ntawd, cov zaj duab xis capacitors yog qhov tsis ntseeg cov khoom siv nyiam hauv cov txheej txheem hluav taws xob ntawm cov tsheb fais fab. Txawm li cas los xij, kom ntseeg tau tias lawv tsim nyog rau kev siv tsheb, cov capacitors no yuav tsum ua tau raws li cov qauv tsheb nruj dua, xws li AEC-Q200, thiab qhia txog kev ua tau zoo txhim khu kev qha hauv qab cov xwm txheej hnyav. Raws li cov kev cai no, kev xaiv thiab kev siv cov capacitors yuav tsum ua raws li cov ntsiab cai no.

Feem ntau, lub tshuab OBC (On-Board Charger) muaj ob lub ntsiab lus tseem ceeb: lub voj voog rectifier uas hloov AC mains fais fab mus rau hauv DC, thiab lub DC-DC fais fab converter uas tsim cov DC voltage uas xav tau rau kev them. Hauv cov txheej txheem no,cov capacitors zaj duab xisnrhiav daim ntawv thov hauv ntau qhov tseem ceeb, suav nrog:

●Kev lim dej EMI
●DC-Txuas
●Kev lim cov zis
●Lub Tank Resonant

02 Cov xwm txheej siv ntawm cov capacitors zaj duab xis hauv OBC

YMINmuaj ntau yam khoom siv capacitor zaj duab xis uas haum rau DC-Link thiab cov ntawv thov lim dej. Qhov tseem ceeb, tag nrho cov khoom no yog AEC-Q200 automotive-grade certified. Tsis tas li ntawd, YMIN muab cov qauv tshwj xeeb tsim rau qhov kub thiab txias thiab av noo (THB), muab kev ywj pheej ntau dua rau cov neeg tsim khoom xaiv cov khoom.

Cov Capacitors DC-Link

Hauv ib lub OBC system, lub DC-Link capacitor yog qhov tseem ceeb rau kev txhawb nqa tam sim no thiab kev lim dej ntawm lub rectifier circuit thiab DC-DC converter. Nws lub luag haujlwm tseem ceeb yog nqus cov tam sim no siab ntawm lub tsheb npav DC-Link, tiv thaiv cov hluav taws xob siab hla lub impedance ntawm DC-Link thiab tiv thaiv lub nra hnyav los ntawm overvoltage.

Cov yam ntxwv ntawm cov zaj duab xis capacitors—xws li kev kam rau siab voltage, capacitance loj, thiab tsis-polarity—ua rau lawv zoo tagnrho rau DC-Link filtering daim ntawv thov.

YMIN'sMDP(H)series yog qhov kev xaiv zoo heev rau DC-Link capacitors, muab:

Cov Capacitors Filtering Output

Txhawm rau txhim kho cov yam ntxwv teb ib ntus ntawm OBC's DC output, xav tau lub capacitor lim dej loj, qis-ESR output. YMIN muab covMDPCov capacitors DC-Link film uas muaj zog tsawg, uas muaj cov yam ntxwv nram qab no:

Cov khoom no muaj kev ua tau zoo heev, kev ntseeg siab, thiab kev hloov pauv tau rau cov kev siv tsheb uas xav tau ntau, ua kom muaj kev ua haujlwm OBC zoo thiab ruaj khov.
