Dzulo, Msonkhano wachinayi wa China Power Electronics and Energy Conversion & Exhibition (CPEEC) ndi Msonkhano wa 28 wa Chaka ndi Chaka wa Maphunziro wa China Power Supply Society (CPSSC) unatsegulidwa kwambiri ku Bao'an Hall ya Shenzhen World Exhibition & Convention Center!
YMIN Electronics idawonekera bwino mu Hall 20, ikuwonetsa mayankho ake m'magawo anayi ofunikira: zamagetsi atsopano amagetsi, ma seva a AI, malo osungira mphamvu a photovoltaic, ndi ma motor drive (ma robot/drones/servo motors).
Malo ochitirako msonkhano anali odzaza ndi alendo, ndipo malo ochitirako misonkhano yaukadaulo anali okongola kwambiri!
Kusanthula mozama kwa mfundo zazikulu za nkhani: Momwe ma capacitor akhala "injini yofunika kwambiri" ya ma semiconductors a m'badwo wachitatu
Mu nkhani yayikulu nthawi ya 2:00 PM dzulo, Cheng Yong, Mtsogoleri wa Uinjiniya wa YMIN Electronics, adapereka nkhani yotchedwa "Kugwiritsa Ntchito Ma Capacitors Mwatsopano mu Mayankho a Semiconductor a M'badwo Wachitatu." Nkhaniyi idayang'ana kwambiri pamavuto akuluakulu amakampani: momwe mungatsimikizire kuti ma capacitor, gawo lofunikira lopanda mphamvu, likugwirizana ndi ukadaulo wapamwamba, wamphamvu, komanso kutentha kwambiri wa ma semiconductor a m'badwo wachitatu (GaN/SiC) kuti atulutse mphamvu zawo zogwirira ntchito. Nkhaniyi idagogomezera kuti "kufananiza" ndi "kudalirika" ndikofunikira kwambiri. Kupanga kwatsopano kwa YMIN sikophweka, koma kapangidwe kogwirizana kuyambira pazinthu ndi kapangidwe mpaka pamlingo wogwiritsira ntchito. Kudzera mu zabwino zazikulu zaukadaulo monga "kuchuluka kwa capacitance, ESR yotsika, kudalirika kwakukulu, ndi kukula kochepa," amathetsa mwachindunji zovuta za mikhalidwe yogwirira ntchito kwambiri, kupereka "maziko olimba a mphamvu" ndi "mphamvu yokhazikika" ya zida zamagetsi zapamwamba.
Kusanthula mozama kwa maphunziro anayi othandiza
1. Yankho la Mphamvu ya AI Server – Kupanga pamodzi ndi Navitas GaN: Mavuto: Kusintha kwa ma frequency apamwamba (>100kHz), mphamvu ya ripple yapamwamba kwambiri (>6A), malo otentha kwambiri (>75℃). Yankho: NtchitoMndandanda wa IDC3ma capacitor a electrolytic otsika a ESR, ESR≤95mΩ, nthawi yogwira ntchito mpaka maola 12000 pa 105℃. Zotsatira: Kuchepa kwa 60% pa kukula konse, kuwonjezeka kwa 1% ~ 2% pakugwira ntchito, ndi kuchepa kwa 10℃ pakukwera kwa kutentha.
2. Infineon GaN MOS 480W Rail Power Supply – Kulowa m'malo mwa Japanese Rubycon: Mavuto: Kugwira ntchito pa kutentha kwakukulu -40℃ ~ 105℃, mphamvu ya ripple current ya pafupipafupi. Yankho: Kuchepa kwa mphamvu ya capacitor yotsika kutentha <10%, kupirira ripple current ya 7.8A. Zotsatira: Kupambana -40℃ kuyambitsa kutentha kochepa komanso mayeso a kutentha kochepa kwambiri okhala ndi chiwongola dzanja cha 100%, kukwaniritsa zomwe makampani oyendetsa sitima amafuna pa moyo wawo wa zaka zoposa 10.
3. Capacitor Yatsopano ya Magetsi a Magalimoto a DC-Link – Kusinthasintha ku ON Semiconductor 300kW Motor Controller: Mavuto: Kusintha pafupipafupi >20kHz, dV/dt > 50V/ns, kutentha kwamlengalenga >105℃ Yankho: ESL <3.5nH, nthawi yogwira ntchito yoposa maola 10,000 pa 125℃, kuwonjezeka kwa 30% kwa mphamvu pa voliyumu iliyonse. Zotsatira: Kugwira ntchito bwino konse kumafika pa 98.5%, kuchuluka kwa mphamvu kumapitirira 45kW/L, ndipo kusiyana kumawonjezeka ndi pafupifupi 5%.
4. Yankho la GigaDevice 3.5kW Charging Pil Yankho · Kugwirizana Kwambiri ndi YMIN Capacitors Mavuto: PFC switching frequency 70kHz, LLC switching frequency 94kHz~300kHz, input-side ripple current yopitilira 17A, kukwera kwakukulu kwa kutentha kwa chip kumakhudza kwambiri moyo. Yankho: Gwiritsani ntchito kapangidwe kofanana ka multi-tab kuti muchepetse ESR/ESL, kuphatikiza ndi GD32G553 MCUs ndi zida za GaNSafe/GeneSiC zimakwaniritsa mphamvu ya 137W/in³: magwiridwe antchito apamwamba a system a 96.2%, power factor (PF) ya 0.999, ndi THD ya 2.7% yokha, kukwaniritsa kudalirika kwakukulu ndi zaka 10-20 za moyo wa magalimoto amagetsi.
Pa chiwonetserochi, chomwe chimayang'ana kwambiri zofunikira kwambiri zama semiconductors a m'badwo wachitatu zama capacitors, malo ochitira masewera olimbitsa thupi a YMIN adasanduka nsanja yosinthira ukadaulo waukadaulo komanso wothandiza. Gulu la mainjiniya ndi makasitomala adachita nawo zokambirana zamoyo komanso zakuya pankhani zazikulu monga kukhazikika kwa ma capacitor pama frequency apamwamba komanso kudalirika kwa nthawi yayitali m'malo otentha kwambiri. Kuyanjana bwino komanso kulumikizana kolondola kunawonetsa bwino kufunika kwa msika kwa ma capacitor opangidwa mdziko muno omwe amagwira ntchito bwino komanso kuzindikira kwake mphamvu ya zinthu za YMIN komanso mayankho aukadaulo.
Gulu la akatswiri linapita kukawona mphamvu ya tchipisi zopangidwa mdziko muno.
Masana a chiwonetserochi, malo owonetsera a YMIN adalandila gulu la akatswiri odziwika bwino kuti asinthane. Gululo, kuphatikizapo katswiri wa maphunziro a Virginia Tech Academy, mkulu wa kafukufuku ndi chitukuko ku Delta Electronics, ndi mapulofesa ochokera ku Shanghai Maritime University, Zhejiang University, ndi Xi'an Jiaotong University, adawonetsa chidwi chachikulu ndi zomwe YMIN yakwaniritsa paukadaulo paulendo wawo. Akatswiriwa adakondwera kwambiri ndi kugwiritsa ntchito kwatsopano kwa mbadwo watsopano wa YMIN wa lithiamu-ion supercapacitors (LIC) mu mphamvu yosungira ya seva ya NVIDIA ya AI GB300 BBU. Yankho ili likuthana mwachindunji ndi zovuta za kukwera kwa mphamvu ya GPU ndi moyo wautali, kukwaniritsa kuchepa kwakukulu kwa kukula ndi kulemera pamene kuthandizira mphamvu yayikulu ya 15–21kW ndi magwiridwe antchito kuphatikiza kukana kwamkati <1mΩ, kuchaja mwachangu kwa mphindi 10, ndi ma cycle miliyoni imodzi. Komanso pakuwonetsedwa panali pulogalamu ya YMIN yodziyimira payokha.Ma capacitor a nyanga yamadzimadzi a IDC3 mndandanda wa IDC3Zopangidwira makamaka magetsi a seva ya AI yamphamvu kwambiri. Ma capacitor awa, omwe nthawi zambiri amakhala ndi kukula kwa 450V 1400μF ndi 30×70mm, amapereka mphamvu yolimba kwambiri, mphamvu yochuluka ya capacitance, komanso moyo wautali, zomwe zimathandiza kwambiri pakukweza mphamvu ndi kudalirika kwa magetsi a seva ya AI. Kuzindikiridwa ndi chidwi kuchokera kwa akatswiri apamwamba awa ndi umboni wabwino kwambiri wa kudzipereka kwa YMIN pakupanga zinthu zatsopano komanso khama lake pothana ndi ntchito zapamwamba.
Kuyika kwa YMIN: Mapulogalamu Othandizira - Pazovuta Zanu Zonse, Pitani ku YMIN
Sitili opanga ma capacitor okha; tadzipereka kukhala gulu lotsogola lapakhomo lomwe lingathe kusintha mitundu yapadziko lonse lapansi. M'magawo monga magalimoto atsopano amagetsi, ma seva a AI, malo osungira mphamvu a photovoltaic, ndi ma drive amafakitale, timapatsa makasitomala mayankho a ma capacitor omwe amapereka magwiridwe antchito apamwamba, kuchuluka kwa mphamvu, komanso kudalirika kwambiri.
