Thaum sib tham txog kev tsim kho tshiab thiab kev txhim kho hauv cov tshuab hluav taws xob ntawm lub tsheb hluav taws xob, kev tsom mus rau feem ntau yog muab tso rau hauv cov khoom tseem ceeb xws li lub ntsiab tswj thiab cov khoom siv hluav taws xob, thaum lub koom haum pab xws li capacitors yuav tau txais kev saib xyuas tsawg. Txawm li cas los xij, cov koom haum pabcuam no muaj kev txiav txim siab rau kev ua haujlwm tag nrho ntawm qhov system. Kab lus no yuav delve rau hauv daim ntawv thov ntawm YMIN zaj duab xis capacitors nyob rau hauv onboard chargers thiab tshawb txog kev xaiv thiab daim ntawv thov ntawm capacitors nyob rau hauv hluav taws xob tsheb.

Ntawm ntau hom capacitor,aluminium electrolytic capacitormuaj keeb kwm ntev thiab tau tuav txoj haujlwm tseem ceeb hauv kev lag luam hluav taws xob hluav taws xob. Txawm li cas los xij, nrog rau kev hloov pauv ntawm cov txheej txheem thev naus laus zis, cov kev txwv ntawm electrolytic capacitors tau dhau los ua pom tseeb. Yog li ntawd, ib qho kev xaiv zoo tshaj - zaj duab xis capacitors - tau tshwm sim.

Piv nrog rau electrolytic capacitors, zaj duab xis capacitors muaj qhov zoo ntawm qhov hluav taws xob endurance, qis sib npaug series tsis kam (ESR), non-polarity, muaj zog stability, thiab ntev lifespan. Cov yam ntxwv no ua rau zaj duab xis capacitors zoo tshaj plaws hauv kev tsim qauv yooj yim, txhim kho ripple tam sim no muaj peev xwm, thiab muab kev ua tau zoo dua nyob rau hauv ib puag ncig hnyav.

Los ntawm kev sib piv cov kev ua tau zoo ntawm zaj duab xis capacitors nrog rau kev siv ib puag ncig ntawm lub tsheb fais fab, nws pom tau tias muaj kev sib raug zoo ntawm ob qho tib si. Raws li xws li, zaj duab xis capacitors yog undoubtedly cov nyiam Cheebtsam nyob rau hauv lub electrification txheej txheem ntawm hluav taws xob tsheb. Txawm li cas los xij, txhawm rau kom ntseeg tau tias lawv tsim nyog rau kev siv tsheb, cov khoom siv hluav taws xob no yuav tsum tau ua raws li cov qauv tsheb nruj dua, xws li AEC-Q200, thiab ua kom pom kev ua tau zoo hauv cov xwm txheej hnyav. Raws li cov kev cai no, kev xaiv thiab kev siv cov capacitors yuav tsum ua raws li cov qauv no.

Ib qho OBC (On-Board Charger) feem ntau muaj ob lub ntsiab lus tseem ceeb: lub tshuab hluav taws xob hloov hluav taws xob uas hloov AC lub zog rau hauv DC, thiab DC-DC lub zog hloov hluav taws xob uas tsim cov DC voltage rau kev them nyiaj. Hauv cov txheej txheem no,zaj duab xis capacitorsnrhiav kev thov hauv ntau qhov chaw tseem ceeb, suav nrog:

●EMI lim
●DC-Txuas
●Tso zis lim
●Resonant Tank

02 Daim ntawv thov scenarios ntawm zaj duab xis capacitors hauv OBC

YMINmuaj ntau yam ntawm cov yeeb yaj kiab capacitor khoom tsim nyog rau DC-Txuas thiab tso zis lim cov ntawv thov. Qhov tseem ceeb, tag nrho cov khoom no yog AEC-Q200 automotive-qib ntawv pov thawj. Tsis tas li ntawd, YMIN muab cov qauv tshwj xeeb tsim rau qhov kub thiab txias (THB) ib puag ncig, muab cov neeg tsim khoom yooj yim dua hauv kev xaiv cov khoom.

DC-Txuas Capacitor

Hauv OBC system, 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 mem tes siab tam sim no ntawm DC-Txuas lub tsheb npav, tiv thaiv cov mem tes siab dhau ntawm qhov impedance ntawm DC-Txuas thiab tiv thaiv lub nra ntawm overvoltage.

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

YMIN covMDP (H)series yog ib qho kev xaiv zoo heev rau DC-Link capacitors, muab:

Output Filtering Capacitor

Txhawm rau txhim kho qhov hloov pauv hloov pauv yam ntxwv ntawm OBC's DC tso zis, yuav tsum muaj qhov loj-capacitance, qis-ESR tso zis lim capacitor. YMIN muab covMDPTsawg-voltage DC-Link zaj duab xis capacitors, uas muaj xws li:

Cov khoom no muaj kev ua tau zoo, kev ntseeg siab, thiab kev hloov pauv rau kev thov kev siv tsheb, kom ntseeg tau tias OBC ua haujlwm tau zoo thiab ruaj khov.
