Izolo, iNgqungquthela yesi-4 ye-China Power Electronics and Energy Conversion & Exhibition (CPEEC) kanye neNgqungquthela Yonyaka Yama-28 Yezemfundo ye-China Power Supply Society (CPSSC) ivulwe kahle eBao'an Hall yeShenzhen World Exhibition & Convention Center!
I-YMIN Electronics ivele kahle eHholo 20, ikhombisa izixazululo zayo ezindaweni ezine eziyinhloko zohlelo lokusebenza: ama-elekthronikhi ezimoto ezintsha zamandla, amaseva e-AI, isitoreji samandla se-photovoltaic, kanye nama-motor drive (amarobhothi/ama-drone/ama-servo motors).
Indawo yayigcwele izivakashi, futhi isimo sokushintshisana kwezobuchwepheshe sasigcwele injabulo!
Ukuhlaziywa okujulile kwezinto ezivelele zenkulumo: Indlela ama-capacitor abe ngayo “injini eyinhloko” yama-semiconductor esizukulwane sesithathu
Enkulumweni eyinhloko ngo-2:00 ntambama izolo, uCheng Yong, uMqondisi Wobunjiniyela be-YMIN Electronics, wethule isethulo esinesihloko esithi “Izicelo Ezintsha Zama-Capacitors Kuzixazululo Ze-Third-Generation Semiconductor.” Isethulo sigxile ephuzwini elibalulekile embonini: indlela yokuqinisekisa ukuthi ama-capacitor, ingxenye ebalulekile engenzi lutho, ahambisana nobuchwepheshe obuphezulu, obunamandla aphezulu, kanye nobuchwepheshe bokushisa obuphezulu be-semiconductors yesizukulwane sesithathu (i-GaN/SiC) ukuze baveze ngempela amandla abo okusebenza. Isethulo sigcizelele ukuthi “ukufanisa” kanye “nokuthembeka” kubalulekile. Ukusungula izinto ezintsha kwe-YMIN akuyona into elula yokufaka esikhundleni, kodwa umklamo wokubambisana kusukela ezintweni zokwakha kanye nesakhiwo kuya ezingeni lesicelo. Ngezinzuzo zobuchwepheshe eziyinhloko ezifana “nobuningi be-capacitance ephezulu, i-ESR ephansi, ukuthembeka okuphezulu, kanye nosayizi omncane,” babhekana ngqo nezinselele zezimo zokusebenza ezimbi kakhulu, bahlinzeka “ngesisekelo samandla” esiqinile kanye “nomgogodla wokuzinza kwe-voltage” wamadivayisi kagesi athuthukile.

Embukisweni, ogxile ezidingweni eziqinile zama-frequency aphezulu, ama-voltage aphezulu, kanye nokushisa okuphezulu kwama-semiconductor esizukulwane sesithathu sama-capacitor, i-YMIN's boot yaguqulwa yaba yipulatifomu yokushintshana ngobuchwepheshe yobungcweti nesebenzayo. Ithimba lobunjiniyela namakhasimende bahlanganyele ezingxoxweni ezinempilo nezijulile ngezindaba eziyinhloko ezifana nokuqina kwama-capacitor kuma-frequency aphezulu kanye nokuthembeka kwesikhathi eside ezindaweni ezishisa kakhulu. Ukusebenzisana okusebenzayo kanye nokuxhumana okunembile kubonise ngokugcwele isidingo esikhulayo semakethe sama-capacitor akhiqizwa ngaphakathi asebenza kahle kanye nokuqashelwa kwayo okuphezulu kwamandla omkhiqizo we-YMIN kanye nezixazululo zobuchwepheshe.
Ithimba lochwepheshe livakashele ukuzobona amandla ama-chips akhiqizwe ekhaya.
Ntambama yombukiso, idokodo le-YMIN lamukele ithimba elidumile lochwepheshe ukuze lishintshane. Ithimba, elihlanganisa isazi se-Virginia Tech Academy, umqondisi we-R&D we-Delta Electronics, kanye noprofesa base-Shanghai Maritime University, e-Zhejiang University, kanye nase-Xi'an Jiaotong University, babonise isithakazelo esikhulu ekuphumeleleni kwezobuchwepheshe be-YMIN ngesikhathi sokuvakasha kwabo. Ochwepheshe bahlabeke umxhwele kakhulu ngokusetshenziswa okusha kwesizukulwane esisha se-YMIN se-lithium-ion supercapacitors (LIC) ekuhlinzekweni kwamandla okusekelayo kweseva ye-AI ye-NVIDIA i-GB300 BBU. Lesi sixazululo sibhekana ngqo nezinselele zokwanda kwamandla e-GPU kanye nokuphila kwesikhathi sokushisa okuphezulu, sifinyelela ukwehla okukhulu kosayizi nesisindo ngenkathi sisekela amandla aphezulu angu-15-21kW ngokusebenza okuhlanganisa ukumelana kwangaphakathi <1mΩ, ukushaja okusheshayo kwemizuzu eyi-10, kanye nemijikelezo eyisigidi esingu-1. Okunye okwaboniswayo kwakhiwe ngokuzimela yi-YMIN.Ama-capacitor e-horn ewuketshezi e-IDC3 ochungechungenizenzelwe ngqo izinsiza zamandla eseva ye-AI enamandla amakhulu. Lawa ma-capacitor, ngokuvamile angu-450V 1400μF kanye no-30×70mm ngobukhulu, anikeza ukumelana kwamandla aphezulu, ubuningi be-capacitance obuphezulu, kanye nokuphila isikhathi eside, enikeza ukwesekwa okubalulekile kokuthuthukisa ubuningi bamandla kanye nokuthembeka kwezinsiza zamandla eseva ye-AI. Ukuqashelwa nokunakwa kwalaba ochwepheshe abaphezulu kuwubufakazi obuhle kakhulu bokuzibophezela kwe-YMIN emisha emisha kanye nemizamo yayo ekubhekaneni nezinhlelo zokusebenza eziphezulu.
Isikhundla sika-YMIN: Izinhlelo Zokusebenza Ze-Capacitor – Kuzo Zonke Izinselele Zakho, Phendukela ku-YMIN
Asibona nje abakhiqizi be-capacitor; sizibophezele ekubeni yiqembu elihamba phambili lasekhaya elikwaziyo ukuthatha indawo yemikhiqizo yamazwe ngamazwe. Emikhakheni efana nezimoto ezintsha zamandla, amaseva e-AI, isitoreji samandla se-photovoltaic, kanye nama-drive ezimboni, sinikeza amakhasimende izixazululo ze-capacitor ezinikeza ukusebenza kahle okuphezulu, ubuningi bamandla aphezulu, kanye nokuthembeka okuphezulu.
