Sanadihii la soo dhaafay, kobcinta kobcinta warshadaha tamarta cusub sida kaydinta sawir-qaadista iyo gawaarida korantada (EVs) waxay keentay koror xooggan oo baahida loo qabo DC-Link capacitors. Marka la soo koobo, DC-Link capacitors waxay door muhiim ah ka ciyaaraan wareegga. Waxay nuugi karaan qulqulka garaaca garaaca sare ee dhamaadka baska waxayna simi karaan korantada baska, iyaga oo hubinaya in IGBT iyo SiC MOSFET furayaasha laga ilaaliyo saamaynta xun ee qulqulka garaaca garaaca sare iyo danab ku meel gaadhka ah inta lagu jiro hawlgalka.
Marka korantada baska ee baabuurta tamarta cusub ay kordho 400V ilaa 800V, baahida loo qabo capacitors filimada ayaa si aad ah u kordhay. Marka loo eego xogta, awoodda rakiban ee rogo-yaasha korantada ee ku saleysan DC-Link capacitors khafiif-film waxay gaareen 5.1117 milyan oo dhejis sanadka 2022, taasoo ka dhigan 88.7% awoodda lagu rakibay ee xakamaynta korantada. Wadista gawaarida ee shirkado badan oo kontoroolka korantada ah sida Tesla iyo Nidec dhamaantood waxay isticmaalaan capacitors filimada DC-Link, kuwaas oo xisaabiya 82.9% awooda rakiban waxayna noqdeen doorashada guud ee suuqa wadista korontada.
Waraaqaha cilmi-baaristu waxay muujinayaan in silikoon IGBT kala badh-buundada, capacitors-dhaqameedka elektiroonigga ah waxaa badanaa lagu isticmaalaa isku xirka DC, laakiin kororka korantada ayaa dhici doona sababtoo ah ESR-ga sare ee capacitors electrolytic. Marka la barbar dhigo xalalka IGBT ee silikoon ku salaysan, SiC MOSFETs waxay leeyihiin soo noqnoqoshada isbeddelka sare, sidaas awgeed xajmiga korantada ee korantada ee isku xirka DC ee wareegga badhanka badhkii waa ka sarreeyaa, taas oo keeni karta hoos u dhaca waxqabadka qalabka ama xitaa dhaawac, iyo inta jeer ee resonant ee capacitors electrolytic waa 4kHz oo keliya, taas oo aan ku filnayn in la nuugo qulqulka hadda ee Siverters MOSFET.
Sidaa darteed, codsiyada DC sida rogayaasha wadista korantada iyo beddelayaasha sawir-qaadista ee leh shuruudaha kalsoonida sare,capacitors filimadainta badan waa la doortaa. Marka la barbardhigo aluminium electrolytic capacitors, faa'iidooyinkooda waxqabadkoodu waa iska caabbinta korantada sare, ESR hoose, aan polarity, waxqabadka xasilloon, iyo nolol dheer, sidaas darteed lagu gaaro iska caabin xoog leh iyo qaabeynta nidaam la isku halleyn karo.
Nidaamyada isticmaalaya capacitors-filim khafiif ah waxay ka faa'iideysan karaan soo noqnoqoshada sare iyo luminta hoose ee SiC MOSFETs waxayna yareeyaan xajmiga iyo miisaanka qaybaha dadban. Cilmi-baarista Wolfspeed waxay muujineysaa in 10kW silikoon-ku-saleysan IGBT inverter uu u baahan yahay 22 aluminium aluminium ah oo korantada ah, halka 40kW SiC inverter kaliya uu u baahan yahay 8 capacitors-filim khafiif ah, iyo aagga PCB sidoo kale si weyn ayaa loo dhimay.
Iyada oo laga jawaabayo baahida suuqa, YMIN Electronics ayaa bilaabayMDP taxane ah capacitors filimada, kuwaas oo adeegsada tignoolajiyada horumarsan iyo agab tayo sare leh si ay ula qabsadaan SiC MOSFET iyo IGBT-based silicon-based. Taxanayaasha MDP waxay ka muuqdaan ESR hoose, danab adkeysi badan, dareere hoose iyo xasilloonida heerkulka sare.
Faa'iidooyinka YMIN Electronics' alaabta capacitor-ka filimada:
Naqshadeynta capacitor filim ee YMIN Electronics waxay qabataa fikradda ESR hoose si loo yareeyo diiqada tamarta iyo luminta tamarta inta lagu jiro beddelka iyo hagaajinta hufnaanta tamarta nidaamka. Waxay leedahay danab heersare ah oo la qiimeeyay, waxay la qabsataa bay'ada tamarta sare, waxayna hubisaa xasilloonida nidaamka.
Taxanayaasha MDP waxay leeyihiin awood kala duwan oo ah 1uF-500uF iyo kala duwanaansho danab ah 500V ilaa 1500V. Waxay leeyihiin qulqulka hoose ee hadda iyo xasilloonida heerkulka sare. Iyada oo loo marayo qalab tayo sare leh iyo habab horumarsan, qaab-dhismeed kuleyl ah oo hufan ayaa loogu talagalay in lagu hubiyo waxqabadka xasilloon ee heerkulka sare, kordhinta nolosha adeegga, iyo bixinta taageero lagu kalsoonaan karo ee nidaamyada korantada korontada. Isla markaana,MDP taxane capacitorscabbirkoodu waa isku dhafan yihiin, cufnaanta awoodda sare, oo adeegsada hababka wax soo saarka khafiifka ah ee hal-abuur leh si loo hagaajiyo is-dhexgalka nidaamka iyo waxtarka, yaraynta cabbirka iyo miisaanka, iyo kordhinta qaadista qalabka iyo dabacsanaanta.
YMIN Electronics DC-Link taxanaha capacitor filimku wuxuu leeyahay 30% horumarinta dulqaadka dv/dt iyo korodhka 30% ee nolosha adeegga, taas oo wanaajisa isku halaynta wareegyada SiC/IGBT, waxay keenaysaa waxtarka-kharashka, oo xalliya dhibaatada qiimaha.
