Faras wanaagsani wuxuu mudan yahay koore wanaagsan! Si aad si buuxda uga faa'iidaysato faa'iidooyinka qalabka SiC, sidoo kale waa lagama maarmaan in la isku dhejiyo nidaamka wareegga leh capacitors ku habboon. Laga soo bilaabo kantaroolka ugu weyn ee baabuurta korantada ilaa awood sare oo cusub oo tamar cusub ah sida inverters photovoltaic, capacitors filimku waxay si tartiib tartiib ah u noqonayaan mid guud, suuquna wuxuu si degdeg ah ugu baahan yahay alaab qiimo sare leh.
Dhowaan, Shanghai Yongming Electronic Co., Ltd. waxay bilawday capacitors filimada taageerada DC, kuwaas oo leh afar faa'iidooyin oo heer sare ah taasoo ka dhigaysa inay ku habboon yihiin jiilka toddobaad ee Infineon IGBTs. Waxay sidoo kale caawiyaan wax ka qabashada caqabadaha xasilloonida, isku halaynta, yaraynta, iyo qiimaha nidaamyada SiC.
Capacitors filimku waxay gaadhaan ku dhawaad 90% dhexgalka codsiyada waditaanka muhiimka ah. Maxay SiC iyo IGBT ugu baahan yihiin?
Sanadihii la soo dhaafay, iyada oo horumarinta degdega ah ee warshadaha tamarta cusub sida kaydinta tamarta, dallacaadda, iyo baabuurta korontada (EVs), baahida loo qabo DC-Link capacitors ayaa si degdeg ah u kordhayay. Si fudud loo dhigo, DC-Link capacitors waxay u dhaqmaan sidii bakhtiiyeyaasha wareegyada, iyagoo nuugaya qulqulka garaaca garaaca sare ee dhamaadka baska iyo hagaajinta korantada baska, sidaas darteed ka ilaalinta IGBT iyo SiC MOSFET wareegyada garaaca garaaca sare iyo saamaynta korantada ku meel gaadhka ah.
Caadi ahaan, capacitors aluminium electrolytic capacitors ayaa loo isticmaalaa codsiyada taageerada DC. Si kastaba ha noqotee, kororka baska ee baabuurta tamarta cusub ee kor u kaca 400V ilaa 800V iyo nidaamyada sawir-qaadista ee u socda 1500V iyo xitaa 2000V, baahida loo qabo capacitors filimada ayaa si weyn kor ugu kacaya.
Xogtu waxay muujineysaa in 2022, awoodda rakiban ee rogoyaasha korantada ee ku saleysan capacitors filimada DC-Link ay gaareen 5.1117 milyan unug, taasoo ka dhigan 88.7% wadarta guud ee la rakibay ee kontaroolada elektiroonigga ah. Shirkadaha hormuudka ka ah kantaroolka elektiroonigga ah sida Fudi Power, Tesla, Tiknoolajiyada Innovance, Nidec, iyo Wiran Power dhamaantood waxay adeegsadaan awoodaha filimka DC-Link ee rogayaasha wadidkooda, oo leh isku-darka awoodda rakiban ee ilaa 82.9%. Tani waxay muujinaysaa in capacitors filimku ay bedeleen capacitors electrolytic sida caadiga ah ee suuqa wadista korontada.
Tani waa sababta oo ah iska caabbinta korantada ugu badan ee aluminium electrolytic capacitors waa qiyaastii 630V. Codsiyada korantada sare iyo kuwa sare ee ka sarreeya 700V, awood badan oo elektrolytic ah ayaa u baahan in lagu xiro si taxane ah oo barbar socda si ay u buuxiyaan shuruudaha isticmaalka, taas oo keenta khasaaro tamar dheeraad ah, kharashka BOM, iyo arrimaha la isku halleyn karo.
Warqad cilmi baaris ah oo ka socota Jaamacadda Malaysia ayaa tilmaamaysa in korantada elektiroonigga ah sida caadiga ah loo isticmaalo isku xirka DC ee silikoon IGBT nus buundada rogrogaysa, laakiin korontadu waxay dhici kartaa sababtoo ah iska caabin u dhigma oo sarreeya (ESR) ee korantada korantada. Marka la barbar dhigo xalalka IGBT ee ku salaysan silikoon, SiC MOSFETs waxay leeyihiin wareegyo beddelaad sare leh, taasoo keentay kororka korantada sare ee isku xirka DC ee beddelayaasha buundada nuska ah. Tani waxay u horseedi kartaa hoos u dhaca waxqabadka qalabka ama xitaa dhaawac, maadaama inta jeer ee soo noqnoqda ee capacitors electrolytic ay tahay 4kHz kaliya, kuma filna inay nuugaan qulqulka hadda jira ee SiC MOSFET rogayaasha.
Sidaa darteed, codsiyada DC ee leh shuruudo la isku halleyn karo oo sarreeya, sida beddelayaasha korantada korantada iyo beddelayaasha sawir-qaadaha, capacitors filimada ayaa sida caadiga ah la doortaa. Marka la barbar dhigo aluminiumka korantada korantada, faa'iidooyinka waxqabadkooda waxaa ka mid ah iska caabbinta korantada oo sarreeya, ESR hoose, koronto la'aan, waxqabad xasilloon, iyo cimri dheer, taas oo awood u siinaysa naqshad nidaam la isku halleyn karo oo leh iska caabin xoog leh.
Intaa waxaa dheer, isticmaalka qalabka filimada ee nidaamka waxay si isdaba joog ah uga faa'iideysan karaan soo noqnoqoshada sare, faa'iidooyinka khasaaraha hooseeya ee SiC MOSFETs, si weyn u yareynaya cabbirka iyo miisaanka qaybaha dadban (inductors, transformers, capacitors) ee nidaamka. Sida laga soo xigtay cilmi-baarista Wolfspeed, 10kW silikoon ku salaysan IGBT inverter wuxuu u baahan yahay 22 aluminium aluminium ah oo korantada ah, halka 40kW SiC inverter kaliya u baahan yahay 8 capacitors filim, si weyn u yareynaya aagga PCB.
YMIN Waxay Soo Bandhigtay Awoodaha Filimada Cusub oo leh Afar Faa'iidooyin oo waaweyn si ay u taageeraan Warshadaha Tamarta Cusub
Si wax looga qabto baahiyaha suuqa ee degdega ah, YMIN waxa ay dhawaan soo bandhigtay MDP iyo MDR taxane ah oo ah capacitors-ka filimada taageerada DC. Isticmaalka hababka wax soo saarka horumarsan iyo agab tayo sare leh, capacitors-yadani waxay si fiican ula jaan qaadayaan shuruudaha hawlgalka ee SiC MOSFETs iyo IGBT-yada ku salaysan silikoon ee hogaamiyaasha semiconductor-ka awooda caalamiga ah sida Infineon.
YMIN's MDP iyo MDR taxanayaasha filimada waxay leeyihiin dhowr astaamood oo xusid mudan: iska caabin hoose oo taxane ah oo u dhigma (ESR), koronto la qiimeeyay, hadda dareere hoose, iyo xasilloonida heerkulka sare.
Marka hore, capacitors filimada YMIN waxay leeyihiin naqshad hoose oo ESR ah, oo si wax ku ool ah u yaraynaysa walaaca korantada inta lagu jiro wareejinta SiC MOSFETs iyo IGBTs-ku-salaysan, taas oo yaraynaysa khasaaraha kapacitor-ka iyo hagaajinta guud ahaan hufnaanta nidaamka. Intaa waxaa dheer, capacitors-yadani waxay leeyihiin danab la qiimeeyay oo sarreeya, oo awood u leh inay u adkeystaan xaaladaha tamarta sare iyo hubinta hawlgalka nidaamka xasilloon.
Taxanaha MDP iyo MDR ee capacitors filimada YMIN waxay bixiyaan kala duwanaansho awood ah 5uF-150uF iyo 50uF-3000uF, iyo kala duwanaanshaha korantada ee 350V-1500V iyo 350V-2200V, siday u kala horreeyaan.
Marka labaad, capacitors filimkii ugu dambeeyay ee YMIN waxay leeyihiin dareere hoose oo hadda ah iyo xasilloonida heerkulka sare. Marka laga hadlayo nidaamyada kontoroolka elektiroonigga ah ee baabuurta korantada, kuwaas oo sida caadiga ah leh awood sare, soo-saarka kulaylka ee ka soo baxa wuxuu si weyn u saameyn karaa nolosha iyo isku halaynta awoodda filimada. Si taas wax looga qabto, taxanaha MDP iyo MDR ee YMIN waxay ku daraan agab tayo sare leh iyo farsamooyinka wax soo saarka ee horumarsan si loo qaabeeyo qaab-dhismeed kuleyl oo la hagaajiyay oo loogu talagalay capacitors. Tani waxay hubinaysaa waxqabadka xasilloon xitaa jawiga heerkulka sare, ka hortagga hoos u dhaca qiimaha capacitor ama fashilka sababtoo ah kor u kaca heerkulka. Intaa waxaa dheer, capacitors-yadani waxay leeyihiin cimri dherer, iyagoo siinaya taageero la isku halayn karo ee nidaamyada korantada.
Marka saddexaad, MDP iyo MDR taxane capacitors ee YMIN waxay muujinayaan cabbir ka yar iyo cufnaanta awoodda sare. Tusaale ahaan, nidaamyada wadista korontada ee 800V, isbeddelku waa in la isticmaalo aaladaha SiC si loo yareeyo cabbirka capacitors iyo qaybaha kale ee aan tooska ahayn, sidaas darteed kor u qaadista miniaturization ee kontaroolada elektiroonigga ah. YMIN waxay shaqaalaysiisay tignoolajiyada wax soo saarka filimada hal-abuurka leh, taas oo aan kordhinaynin oo kaliya isdhexgalka nidaamka guud iyo hufnaanta laakiin sidoo kale waxay yaraynaysaa cabbirka nidaamka iyo miisaanka, kor u qaadida qaadista iyo dabacsanaanta aaladaha.
Guud ahaan, taxanaha capacitor-ka filimka YMIN ee DC-Link wuxuu bixiyaa 30% horumarinta dv/dt awoodda u adkeysiga iyo korodhka 30% ee cimriga marka loo eego kuwa kale ee filimada ee suuqa. Tani ma aha oo kaliya inay bixiso isku halaynta wanaagsan ee wareegyada SiC/IGBT laakiin waxay sidoo kale bixisaa waxtarka-wax-ku-oolnimada, ka gudubka caqabadaha qiimaha ee codsiga baahsan ee capacitors filimada.
Hormood ahaan warshad ahaan, YMIN waxay si qoto dheer ugu lug lahayd beerta capacitor in ka badan 20 sano. Awoodeeda korantada sare ayaa si xasilan loogu dabaqay aagagga dhamaadka-sare sida dusha OBC, tuulan tamar cusub, rogo-rogayaasha, iyo robotyada warshadaha sanado badan. Jiilkan cusub ee alaabta capacitor film xalliyo caqabadaha kala duwan ee film capacitor habka wax soo saarka xakamaynta iyo qalabka, ayaa dhamaystirtay shahaado isku halaynta shirkadaha caalamiga ah ee hormuudka ka ah, oo la gaadhay codsi baaxad weyn, caddaynaya isku halaynta alaabta ee macaamiisha waaweyn. Mustaqbalka, YMIN waxay ka faa'iidaysan doontaa ururinteeda farsamada muddada-dheer si ay u taageerto horumarka degdega ah ee warshadaha tamarta cusub oo leh isku halleyn sarreeya iyo alaabooyin waxtar leh.
