Thaum tham txog kev hloov pauv tshiab thiab kev txhim kho hluav taws xob hluav taws xob ntawm cov chaw tsim hluav taws xob thiab cov khoom siv hluav taws xob tseem ceeb, thaum cov khoom siv hluav taws xob zoo li capacitors zoo li capital. Txawm li cas los xij, cov txheej txheem no muaj kev txiav txim siab txiav txim siab rau ntawm tag nrho cov kev ua tau zoo ntawm lub system. Kab lus no yuav delve rau hauv daim ntawv thov ntawm YMIN Zaj duab xis capacitors hauv onboard chargers thiab tshawb cov kev xaiv thiab kev thov ntawm cov tsheb hluav taws xob hauv cov tsheb hluav taws xob.
Ntawm ntau hom capacitors,Aluminium Electrolytic CapacitorsMuaj keeb kwm ntev thiab tau nyob ib txoj haujlwm tseem ceeb hauv thaj teb ntawm lub zog hluav taws xob. Txawm li cas los xij, nrog rau kev hloov kho ntawm cov kev xav tau ntawm kev siv thev naus laus zis, cov kev txwv ntawm electrolytic capacitors tau dhau los ua lwm yam. Raws li qhov tshwm sim, kev xaiv zoo tshaj plaws-zaj yeeb yaj kiab capacitors-tau tawm.
Piv rau cov electrolytic capacitors muaj cov ntsiab lus tseem ceeb ntawm cov txiaj ntsig kev ua kom tsis kam tshaj plaws (ESR), tsis yog-polarabity, thiab lub neej ruaj khov. Cov yam ntxwv no ua rau cov yeeb yaj kiab tsim tau zoo tshaj plaws hauv kev tsim qauv yooj yim, txhim kho cov peev txheej tam sim no, thiab muab cov kev ua tau zoo tshaj plaws nyob rau hauv cov xwm txheej hnyav hauv kev ua haujlwm hnyav nyob rau hauv cov kev mob teeb meem.
Cov lus: sib piv kev ua tau zoo ntawmZaj Duab Xis Capasthiab txhuas electrolytic capacitors
Los ntawm piv cov kev ua yeeb yam ntawm zaj duab xis capinitors nrog rau ib puag ncig cov chaw ntawm hluav taws xob tsheb, nws yog pom tseeb tias muaj qib siab ntawm ob qho. Raws li xws li, zaj yeeb yaj kiab capacitors tsis ntseeg qhov xav tau cov txheej txheem hluav taws xob hauv hluav taws xob hauv hluav taws xob. Txawm li cas los xij, txhawm rau paub tseeb tias lawv cov kev haum rau cov ntawv thov kho tsheb, xws li AEC-Q200, thiab ua pov thawj txhim khu kev ua haujlwm nyob rau hauv cov xwm txheej huab. Raws li cov kev xav tau no, kev xaiv thiab kev thov ntawm capacitors yuav tsum ua raws li cov ntsiab cai no.

Ib qho OBC (ntawm-board charger) feem ntau muaj ob qho tseem ceeb: thiab DC-DC lub zog hloov pauv uas tau tsim cov DC voltage uas yuav tsum them. Hauv txoj kev no,Zaj Duab Xis CapasNrhiav daim ntawv thov hauv ntau qhov chaw tseem ceeb, suav nrog:
●Eman lim
●DC-txuas
●Kev Tawm Laij Lim
●Resonant tank

Txiv sawvMuaj ntau ntawm zaj duab xis Capacitor Cov khoom lag luam haum rau DC-txuas thiab cov zis kev siv cov kev siv. Tshwj xeeb, tag nrho cov khoom lag luam yog AEC-Q200 Automotive Qib-Qib. Ib qho ntxiv, YMIN muab cov qauv tshwj xeeb tsim rau kev kub kub thiab cov av noo (thb) ib puag ncig, kev tsim cov kev tsim kom muaj ntau dua hauv kev xaiv tiv thaiv ntau.
DC-Txuas Capacitors
Hauv OBC system, DC-txuas Capacitor yog qhov tseem ceeb rau kev txhawb nqa tam sim no thiab lim ntawm Rectifier Circuit Court thiab DC-DC converter. Nws lub luag haujlwm tseem ceeb yog nqus cov pulse rements ntawm lub npav DC-txuas thoob plaws lub DC-txuas ntawm DC-txuas ntawm DC-txuas ntawm DC-txuas ntawm DC-txuas ntawm DC-txuas thiab kev tiv thaiv cov thauj khoom los ntawm overvoltage.
Cov yam ntxwv hauv lub ntsej muag ntawm cov yeeb yaj kiab capacitors-xws li kev txhawb siab siab, thiab tsis yog-polarity-ua rau lawv zoo tagnrho rau cov ntawv thov dC-txuas.
Ymin'sMDP (h)Series yog qhov kev xaiv zoo rau DC-txuas capacitors, muab:
