Tus nees zoo tsim nyog tau lub eeb zoo! Txhawm rau kom muaj txiaj ntsig zoo ntawm SiC cov cuab yeej, nws kuj tseem yuav tsum tau ua ke nrog cov kab hluav taws xob sib txuas nrog cov khoom siv hluav taws xob tsim nyog. Los ntawm lub ntsiab tsav tswj nyob rau hauv hluav taws xob tsheb mus rau high-power tshiab scenarios zoo li photovoltaic inverters, zaj duab xis capacitors yog maj ua mainstream, thiab kev ua lag luam urgently xav tau high-nqi-kev ua tau zoo cov khoom.
Tsis ntev los no, Shanghai Yongming Electronic Co., Ltd. launched DC txhawb zaj duab xis capacitors, uas muaj plaub qhov zoo tshaj plaws ua rau lawv haum rau Infineon lub xya tiam IGBTs. Lawv kuj pab daws cov teeb meem ntawm kev ruaj ntseg, kev cia siab, kev siv me me, thiab tus nqi hauv SiC systems.
Zaj duab xis capacitors ua tiav ze li ntawm 90% nkag mus rau hauv daim ntawv thov tsav tseem ceeb. Vim li cas SiC thiab IGBT xav tau lawv?
Nyob rau hauv xyoo tas los no, nrog rau kev loj hlob sai ntawm kev lag luam hluav taws xob tshiab xws li lub zog cia, them nyiaj, thiab hluav taws xob tsheb (EVs), qhov kev thov rau DC-Link capacitors tau nce sai heev. Cias muab tso, DC-Link capacitors ua raws li buffers nyob rau hauv circuits, absorbing siab mem tes tam sim no los ntawm lub tsheb npav kawg thiab smoothing tsheb npav voltage, yog li tiv thaiv IGBT thiab SiC MOSFET keyboards los ntawm high mem tes tam sim no thiab transient voltage cuam tshuam.
Feem ntau, txhuas electrolytic capacitor yog siv hauv DC kev txhawb nqa daim ntawv thov. Txawm li cas los xij, nrog lub tsheb npav voltage ntawm lub zog tshiab tsheb nce los ntawm 400V rau 800V thiab cov tshuab photovoltaic txav mus rau 1500V thiab txawm tias 2000V, qhov kev thov rau zaj duab xis capacitors tau nce siab.
Cov ntaub ntawv qhia tau hais tias nyob rau hauv 2022, lub peev xwm nruab ntawm hluav taws xob tsav inverters raws li DC-Link zaj duab xis capacitors mus txog 5.1117 lab units, suav txog 88.7% ntawm tag nrho cov peev txheej ntawm kev tswj hluav taws xob. Cov tuam txhab tswj hluav taws xob xws li Fudi Power, Tesla, Inovance Technology, Nidec, thiab Wiran Power txhua tus siv DC-Link zaj duab xis capacitors hauv lawv lub zog tsav, nrog rau kev sib xyaw ua ke muaj peev xwm txog li 82.9%. Qhov no qhia tau hais tias zaj duab xis capacitors tau hloov electrolytic capacitors raws li lub ntsiab hauv lub khw muag khoom hluav taws xob.
Qhov no yog vim qhov siab tshaj qhov tsis kam ntawm txhuas electrolytic capacitors yog kwv yees li 630V. Hauv kev siv hluav taws xob siab thiab hluav taws xob siab siab tshaj 700V, ntau lub tshuab hluav taws xob electrolytic yuav tsum tau txuas nrog hauv series thiab sib npaug kom tau raws li qhov yuav tsum tau siv, uas ua rau lub zog poob ntxiv, BOM tus nqi, thiab cov teeb meem kev ntseeg tau.
Ib daim ntawv tshawb fawb los ntawm University of Malaysia qhia tias electrolytic capacitors feem ntau yog siv nyob rau hauv DC txuas ntawm silicon IGBT ib nrab-bridge inverters, tab sis voltage surges tuaj yeem tshwm sim vim qhov sib npaug sib npaug series (ESR) ntawm electrolytic capacitors. Piv rau silicon-raws li IGBT cov kev daws teeb meem, SiC MOSFETs muaj kev hloov pauv ntau dua, ua rau muaj qhov hluav taws xob ntau dua amplitudes hauv DC txuas ntawm ib nrab-bridge inverters. Qhov no tuaj yeem ua rau cov cuab yeej ua haujlwm tsis zoo lossis puas tsuaj, vim tias qhov zaus ntawm electrolytic capacitors tsuas yog 4kHz, tsis txaus los nqus cov ripple tam sim no ntawm SiC MOSFET inverters.
Yog li ntawd, nyob rau hauv DC daim ntawv thov nrog kev ntseeg siab dua, xws li hluav taws xob tsav inverters thiab photovoltaic inverters, zaj duab xis capacitors feem ntau xaiv. Piv nrog rau txhuas electrolytic capacitors, lawv cov kev ua tau zoo muaj xws li kev tiv thaiv hluav taws xob ntau dua, qis ESR, tsis muaj polarity, kev ua haujlwm ruaj khov dua, thiab lub neej ntev dua, ua kom muaj kev txhim khu kev qha ntau dua nrog kev ua haujlwm zoo dua.
Tsis tas li ntawd, siv zaj duab xis capacitors nyob rau hauv lub kaw lus tuaj yeem rov ua kom muaj qhov ua haujlwm siab, tsis tshua muaj txiaj ntsig zoo ntawm SiC MOSFETs, txo qhov loj thiab qhov hnyav ntawm cov khoom siv passive (inductors, transformers, capacitors) hauv qhov system. Raws li Wolfspeed kev tshawb fawb, 10kW silicon-raws li IGBT inverter yuav tsum tau 22 txhuas electrolytic capacitors, whereas 40kW SiC inverter tsuas xav tau 8 zaj duab xis capacitors, zoo heev txo qhov PCB cheeb tsam.
YMIN Launches New Film Capacitors nrog Plaub Qhov Zoo Tshaj Plaws los txhawb Kev Lag Luam Tshiab Zog
Txhawm rau hais txog kev xav tau ntawm kev lag luam sai, YMIN tsis ntev los no tau tshaj tawm MDP thiab MDR series ntawm DC txhawb nqa zaj duab xis capacitors. Siv cov txheej txheem tsim khoom thiab cov ntaub ntawv zoo, cov capacitors no zoo kawg nkaus ua tau raws li kev ua haujlwm ntawm SiC MOSFETs thiab silicon-based IGBTs los ntawm cov thawj coj thoob ntiaj teb lub zog semiconductor xws li Infineon.
YMIN's MDP thiab MDR series zaj duab xis capacitors muaj ob peb yam tseem ceeb: qis dua qhov sib npaug series tsis kam (ESR), siab dua qhov ntsuas hluav taws xob, txo qis tam sim no, thiab kub siab dua.
Ua ntej, YMIN's zaj duab xis capacitors muaj qhov tsawg ESR tsim, zoo txo qhov kev ntxhov siab thaum lub sij hawm hloov ntawm SiC MOSFETs thiab silicon-based IGBTs, yog li txo qis capacitor poob thiab txhim kho tag nrho cov system efficiency. Tsis tas li ntawd, cov capacitors no muaj qhov ntsuas hluav taws xob ntau dua, muaj peev xwm tiv taus qhov hluav taws xob ntau dua thiab ua kom lub zog ruaj khov.
MDP thiab MDR series ntawm YMIN zaj duab xis capacitors muaj peev xwm ntawm 5uF-150uF thiab 50uF-3000uF, thiab qhov hluav taws xob ntau ntawm 350V-1500V thiab 350V-2200V, feem.
Qhov thib ob, YMIN qhov tseeb zaj duab xis capacitors muaj qis dua tam sim no thiab kub siab dua. Nyob rau hauv cov ntaub ntawv ntawm lub tsheb hluav taws xob hluav taws xob tswj cov tshuab, uas feem ntau muaj lub zog siab, qhov tshwm sim thaum tshav kub kub tuaj yeem cuam tshuam rau lub neej ntev thiab kev cia siab ntawm zaj duab xis capacitors. Txhawm rau hais txog qhov no, MDP thiab MDR series los ntawm YMIN suav nrog cov ntaub ntawv zoo thiab cov txheej txheem tsim khoom zoo tshaj plaws los tsim cov qauv thermal zoo rau cov capacitors. Qhov no ua kom ruaj khov ua haujlwm txawm tias nyob rau hauv qhov chaw kub kub, tiv thaiv tus nqi capacitor degradation lossis tsis ua haujlwm vim qhov kub nce. Tsis tas li ntawd, cov capacitors no muaj lub neej ntev dua, muab kev txhawb nqa zoo dua rau cov tshuab hluav taws xob hluav taws xob.
Thib peb, MDP thiab MDR series capacitors los ntawm YMIN feature me me thiab ntau zog ceev. Piv txwv li, nyob rau hauv 800V hluav taws xob tsav systems, tus qauv yog siv SiC li los txo qhov luaj li cas ntawm capacitors thiab lwm yam passive Cheebtsam, yog li txhawb miniaturization ntawm hluav taws xob tswj. YMIN tau ua haujlwm tshiab tsim cov yeeb yaj kiab thev naus laus zis, uas tsis yog tsuas yog ua kom lub zog tag nrho kev sib koom ua ke thiab kev ua haujlwm tau zoo tab sis kuj txo qhov system loj thiab qhov hnyav, txhim kho kev txav mus los thiab yooj yim ntawm cov khoom siv.
Zuag qhia tag nrho, YMIN's DC-Link zaj duab xis capacitor series muaj 30% kev txhim kho hauv dv / dt withstand peev thiab 30% nce hauv lifespan piv rau lwm cov yeeb yaj kiab capacitors ntawm kev ua lag luam. Qhov no tsis yog tsuas yog muab kev ntseeg tau zoo dua rau SiC / IGBT circuits tab sis kuj muaj txiaj ntsig zoo dua, kov yeej cov nqi teeb meem hauv kev siv dav dav ntawm cov yeeb yaj kiab capacitors.
Raws li ib qho kev lag luam pioneer, YMIN tau koom nrog hauv kev lag luam capacitor rau ntau tshaj 20 xyoo. Nws cov high-voltage capacitors tau ruaj khov rau hauv high-end teb xws li onboard OBC, tshiab zog them pawg, photovoltaic inverters, thiab industrial robots tau ntau xyoo. Lub cim tshiab ntawm cov khoom siv capacitor no daws ntau yam teeb meem hauv cov txheej txheem kev tsim cov khoom siv capacitor thiab cov khoom siv, tau ua tiav cov ntawv pov thawj kev ntseeg siab nrog cov tuam txhab thoob ntiaj teb, thiab ua tiav daim ntawv thov loj, ua pov thawj cov khoom lag luam kev ntseeg siab rau cov neeg siv khoom loj. Nyob rau hauv lub neej yav tom ntej, YMIN yuav leverage nws lub sij hawm ntev kev tsub zuj zuj ntawm kev txhawb nqa kev loj hlob sai ntawm lub zog tshiab kev lag luam nrog kev ntseeg siab thiab nqi-zoo capacitor khoom.
