Tus nees zoo tsim nyog tau lub siab zoo! Txhawm rau kom muaj kev sib zog ua kom zoo ntawm cov khoom noj uas muaj nplej, nws tseem yuav tsum tau ua kom muaj kev sib tw nrog captuit system nrog tsim nyog capacitors. Los ntawm lub zog tsav tswj hauv hluav taws xob tsheb rau high-power caperters, zaj yeeb yaj kiab capecters, thiab kev ua lag luam nrawm xav tau cov khoom lag luam siab ntev.
Tsis ntev los no, Shanghai Yongming Electronic Co., Ltd. Tau ua tiav cov yeeb yaj kiab zoo nkauj, uas muaj plaub qhov zoo tshaj plaws ua rau lawv haum rau infineon thib xya-tiam igbts. Lawv kuj pab daws cov kev cov nyom ntawm kev muaj kev ruaj khov, kev ntseeg tau, miniaturization, thiab tus nqi nyob rau hauv cov puab.
Zaj duab xis capacitors ua tau li 90% kev nkag mus rau hauv cov ntawv thov tsav lub zog tseem ceeb. Vim li cas thiaj ua Sic thiab igbt xav tau lawv?
Nyob rau hauv xyoo tsis ntev los no, nrog txoj kev loj hlob sai ntawm kev lag luam kev lag luam tshiab xws li lub zog cia, them nyiaj, thiab cov hluav taws xob (EVS), qhov kev thov hluav taws xob capacitors tau nce zuj zus. Tsuas yog tso, DC-txuas capacitors ua raws li cov buffers nyob rau hauv lub voj voog, absing tsheb voltej, yog li kev tiv thaiv lub tsheb loj thiab cov roj ntsha siab hloov pauv thiab cov hluav taws xob hloov chaw.
Feem ntau, txhuas electrolytic capacitors siv hauv DC cov ntawv thov txhawb nqa. Txawm li cas los xij, nrog lub tsheb npav hluav taws xob ntawm cov tsheb hluav taws xob tshiab nce ntawm 400v rau 800v thiab txawm tias muaj duab ua yeeb yam tau nce siab.
Cov ntaub ntawv qhia tau hais tias nyob rau hauv 2022, lub peev xwm teeb tsa ntawm hluav taws xob tsav mus txog 5.111 teev rau 88.7% ntawm tag nrho cov peev txheej ntawm kev tswj hluav taws xob. Cov ua rau cov tuam txhab tswj khoom siv hluav taws xob xws li FUDI Hwjchim, Nidec, thiab Wiran Hwj chim tag nrho cov yeeb yaj kiab, nrog lub peev xwm sib xyaw ua ke sib npaug ntawm txog 82.9%. Qhov no qhia tau tias zaj duab xis capacitors tau hloov cov khoom electrolytic zoo li cov ntsiab lus hauv hluav taws xob tsav khw.
Qhov no vim tias qhov siab tshaj plaws hluav taws xob tiv thaiv ntawm txhuas electrolytic capacitors yog kwv yees li 630V. Hauv cov kev siv hluav taws xob siab thiab cov ntaub ntawv muaj zog siab dua 700V, txuas ntxiv kom tau txais kev pab cuam tshuam, uas coj cov teeb meem ntxiv, thiab cov teeb meem kev ntseeg tau.
Cov ntawv tshawb fawb los ntawm University of Malaysia qhia tias cov chaw ua hauj lwm electrolytic feem ntau yuav tshwm sim vim yog qhov kev sib npaug ntawm cov hluav taws xob sib xyaw (ESR) ntawm electrolytic capacitors. Piv rau cov kev daws teeb meem silicon-based igbt, sic Mosfets tau hloov ntau zaus hauv DC txuas ntawm ib nrab-choj In Inverters. Qhov no tuaj yeem ua rau ntaus ntawv ua rau muaj kev cuam tshuam lossis muaj kev puas tsuaj ntawm cov hluav taws xob tsuas yog 4kHz, tsis txaus ntseeg ntawm Sic Memel of Sic Mosfet Inverters.
Yog li ntawd, hauv DC daim ntawv thov nrog kev ntseeg siab dua cov kev xav tau, xws li cov tshuab hluav taws xob thiab photovoltai capervitors yog feem ntau xaiv. Piv rau txhuas electrolytic capacitors, lawv cov kev ua tau zoo muaj zog, tsawg dua kev ua tau zoo, thiab ntev ruaj khov, thiab siv zog ntau dua nrog cov muaj zog ripple tiv thaiv.
Tsis tas li ntawd, siv cov yeeb yaj kiab capacitors hauv lub kaw lus tuaj yeem ua kom loj dua ntawm cov neeg muaj txiaj ntsig, kev ua haujlwm qis ntawm cov khoom sib txawv (inductors, capacers, capacitors) hauv lub system. Raws li kev tshawb fawb Wolfspeed, ib qho 10KW invicon-based inverter yuav tsum tau 22 txhuas capacitors, muaj kev txo qis ntawm thaj chaw PCB.
Ymin Tso Tawm Tshiab Zaj Duab Xis Capacitors Nrog Plaub Qhov Loj Loj Los Txhawb Kev Lag Luam Tshiab
Yuav tsum tau tshaj tawm cov khoom lag luam nrawm, YMIN tau nyuam qhuav pib rau DC Support Filmitors. Kev siv cov txheej txheem tsim kev tsim kho kom zoo thiab cov khoom siv zoo, cov peev txheej zoo tshaj plaws nrog cov thawj coj ntawm ntiaj teb no xws li infineon.
Ymin's MDP thiab MDR series zaj duab xis muaj ntau cov nta uas tsis muaj ntau: ESR), qis dua cov kev xau dej qis, thiab ntau dua qhov kub.
Firstly, Ymin zaj nkauj ua yeeb yaj kiab capacitors muaj kev cuam tshuam uas tsis muaj kev ntxhov siab ntawm cov txiv neej uas tau hloov pauv thiab ua kom muaj peev xwm ntawm cov khoom siv sic Ib qho ntxiv, cov capacitors muaj ntau dua rated voltage, muaj peev xwm ntawm nrog nrog kev ua haujlwm siab dua thiab ua kom muaj kev ua haujlwm ruaj khov.
MDP thiab MDR Series muaj kev ua yeeb yaj kiab capacitors muaj Capacitance Ranges muaj kev phom sij ntawm 350V-1500v thiab 350V-2200V, feem.
Thib ob, YMIN qhov tseeb zaj duab xis capinors tshiab muaj qis dua cov dej xau tam sim no thiab ntau dua qhov kub. Nyob rau hauv rooj plaub ntawm hluav taws xob tsheb hluav taws xob tswj lub tshuab, uas feem ntau muaj lub zog loj, lub zog cua kub ua rau muaj kev cuam tshuam ntau dhau los ntawm kev ua neej muaj peev xwm cuam tshuam nrog kev siv hluav taws xob. Txhawm rau hais txog qhov no, MDP thiab MRDR Series thiab cov txheej txheem tsim kev tsim khoom zoo thiab cov qauv tsim kev tsim khoom ua kom zoo dua rau cov hluav taws xob. Qhov no ua kom muaj kev ua tau ruaj khov txawm tias muaj capacitor muaj nqi degradation lossis tsis ua hauj lwm vim qhov ntsuas kub. Tsis tas li ntawd, cov capacitors muaj lub neej ntev dua, muab kev txhawb nqa ntau rau lub zog hluav taws xob.
Thib peb, MDP thiab MDR Series Capitors los ntawm Ymin feature qhov loj me thiab siab dua lub zog ceev. Piv txwv li, nyob rau hauv 800v hluav taws xob cov hluav taws xob drive tshuab, cov qauv hluav taws xob yog siv cov khoom siv qub los txo qhov loj me ntawm capacitors thiab lwm yam kev sib tw, yog li kev txhawb nqa miniaturization ntawm kev tswj hluav taws xob. Ymin tau ua haujlwm tshiab kev ua yeeb yaj kiab tsim kev lag luam, uas tsis tsuas yog ua kom muaj kev sib xyaw ua ke tag nrho thiab kuj txo qhov chaw nres nkoj thiab qhov hnyav, txhim kho cov khoom siv hluav taws xob.
Zuag qhia tag nrho, Ymin's DC-Txuas Zaj Duab Xis Capacitor Series Muaj 30% nce withstand muaj peev xwm thiab 30% nce ntxiv rau lwm zaj yeeb yaj kiab capacitors ntawm kev ua lag luam. Qhov no tsis tsuas yog ua kom muaj kev ntseeg siab zoo dua rau SIC / IGT Lircuits tab sis kuj tseem muaj txiaj ntsig zoo ntawm cov txiaj ntsig zoo hauv kev siv tshuaj tiv thaiv zaj duab xis.
Raws li kev lag luam tho kev lag luam, Ymin tau ua siab loj hauv lub capacitor tuam teb tau ntau tshaj 20 xyoo. Nws cov-voltage capacitors tau raug tsim nyog nyob rau hauv high-end fields xws li onboard lub zog tseem ceeb piles, thiab cov neeg hlau muaj kev lag luam rau ntau xyoo. Lub cim tshiab ntawm zaj duab xis cov khoom siv ntau yam kev sib tw hauv zaj duab xis, thiab ua tiav cov khoom lag luam loj Nyob rau yav tom ntej, YMIN yuav rub tawm nws lub sijhawm ntev kev sib txhawb los txhawb kev lag luam sai nrog cov khoom lag luam zoo thiab tus nqi siv tau nqi.
