Inanahi, i whakatuwheratia te 4 o ngā Huihuinga me ngā Whakaaturanga Hikohiko me te Whakawhitinga Pūngao o Haina (CPEEC) me te 28 o ngā Huihuinga Mātauranga ā-Tau o te China Power Supply Society (CPSSC) i te Whare Bao'an o te Pokapū Whakaaturanga me te Huihuinga o te Ao o Shenzhen!
I puta kaha mai a YMIN Electronics ki te Whare 20, e whakaatu ana i ana otinga i roto i ngā wāhanga tono matua e whā: ngā hikohiko waka pūngao hou, ngā tūmau AI, te rokiroki pūngao photovoltaic, me ngā puku motuka (ngā karetao/ngā rererangi rererangi/ngā motuka servo).
Kī tonu te wāhi i te tini o ngā manuhiri, ā, he oraora te āhuarangi mō te whakawhitiwhiti kōrero hangarau!
He tātaritanga hōhonu o ngā kaupapa matua o te whaikōrero: Me pēhea te hurihanga o ngā pūnga hei "mīhini matua" o ngā haurua-ā-ira tuatoru o te whakatupuranga
I roto i tētahi whaikōrero matua i te 2:00 PM inanahi, i tukuna e Cheng Yong, te Kaiwhakahaere Hangarau o YMIN Electronics, tētahi whakaaturanga ko "Ngā Whakamahinga Auaha o ngā Pūnga i roto i ngā Otinga Ārahi-whakatupuranga Tuatoru." I arotahi te whakaaturanga ki tētahi āhuatanga uaua matua o te umanga: me pēhea te whakarite kia mau tonu ngā pūnga, he wāhanga tino kore mahi, ki ngā hangarau auau-tiketike, ngaohiko-tiketike, me te pāmahana-tiketike o ngā ārahi-whakatupuranga tuatoru (GaN/SiC) kia tino whakaputa i tō rātou pūmanawa mahi. I whakanuia e te whakaaturanga he mea nui te "taurite" me te "pono". Ehara te auahatanga a YMIN i te whakakapinga ngāwari, engari he hoahoa mahi tahi mai i ngā rauemi me te hanganga ki te taumata tono. Mā roto i ngā painga hangarau matua pēnei i te "kiato kaha teitei, te ESR iti, te pono teitei, me te rahi iti," ka aro tika rātou ki ngā wero o ngā āhuatanga whakahaere tino kino, ka whakarato i tētahi "tūāpapa pūngao" pakari me te "matua whakapūmau ngaohiko" mō ngā taputapu hiko matatau.
He tātaritanga hōhonu o ngā rangahau take mahi e whā
1. Otinga Pūnaha Hiko Tūmau AI – Hoahoa tahi me Navitas GaN: Ngā Wero: Whakawhiti auau-teitei (>100kHz), iahiko riu tino teitei (>6A), taiao pāmahana-teitei (>75℃). Otinga: Ngā WhakamahingaRaupapa IDC3ngā pūnga hiko iti-ESR, ESR≤95mΩ, te roa o te ora tae atu ki te 12000 hāora i te 105℃. Ngā Hua: He 60% te hekenga o te rahi katoa, he 1%~2% te pikinga o te pai, me te 10℃ te hekenga o te pikinga o te pāmahana.
2. Pūnaha Hiko Rerewē Infineon GaN MOS 480W – Te Whakakapi i te Rubycon Hapanihi: Ngā Wero: He whānui te awhe pāmahana mahi -40℃~105℃, te pānga o te au rerewē auau teitei. Otinga: Te tere whakahekenga kaha pāmahana iti o ngā pūnga hiko <10%, ka tu atu ki te au rerewē o te 7.8A. Ngā Hua: Ka paahitia ngā whakamātautau tīmatanga pāmahana iti me te huringa pāmahana teitei-iti -40℃ me te tere paahi 100%, ka tutuki i te whakaritenga a te umanga rerewē kia neke atu i te 10 tau te roa o te ora ratonga.
3. Pūngao Hononga-DC Waka Pūngao Hou – Te Whakarerekē ki te Kaiwhakahaere Motuka ON Semiconductor 300kW: Ngā Wero: Auautanga whakawhiti >20kHz, dV/dt > 50V/ns, pāmahana taiao >105℃ Otinga: ESL <3.5nH, roanga ora neke atu i te 10,000 hāora i te 125℃, pikinga 30% o te kaha mō ia rōrahi wae. Ngā Hua: Neke atu i te 98.5% te pai o te whai huatanga whānui, neke atu i te 45kW/L te kiato mana, ā, kua whakapaitia te whānuitanga mā te 5%.
4. Otinga Puranga Utu GigaDevice 3.5kW · Ngā Wero Mahi Tahi Hōhonu me ngā Pūnga YMIN: Auau whakawhiti PFC 70kHz, auau whakawhiti LLC 94kHz~300kHz, neke atu i te 17A te iahiko riu taha-tāuru, ka nui ake te pānga o te pikinga pāmahana maramara nui ki te roa o te ora. Otinga: Whakamahia he hanganga whakarara maha-ripa hei whakaiti i te ESR/ESL, me te whakakotahitanga me ngā MCU GD32G553 me ngā taputapu GaNSafe/GeneSiC ka tutuki he mātotoru mana o te 137W/in³: ko te pai o te pūnaha he 96.2%, ko te tauwehenga mana (PF) he 0.999, me te THD he 2.7% noa iho, e tutuki ana i ngā whakaritenga pono teitei me te roa o te ora 10-20 tau o ngā puranga utu waka hiko.
I te whakaaturanga, i arotahi ki ngā whakaritenga tino pakari mō ngā haurua-teitei, ngā ngaohiko-teitei, me ngā pāmahana-teitei o ngā haurua-ā-ira tuatoru o te whakatupuranga mō ngā pūnga, ka huri te whare whakaaturanga a YMIN hei tūāpapa whakawhitiwhiti hangarau ngaio me te whai hua. I uru te tīma hangarau me ngā kiritaki ki ngā kōrero hihiri me te hōhonu mō ngā take matua pēnei i te pumau o te pūnga i ngā auau teitei me te pono mō te wā roa i roto i ngā taiao pāmahana-teitei. Ko te taunekeneke whai hua me ngā hononga tika i whakaatu katoa i te pikinga o te hiahia o te mākete mō ngā pūnga mahi-teitei i hangaia i te motu me tōna mōhio nui ki te kaha o te hua me ngā otinga hangarau a YMIN.
I tae atu tētahi rōpū tohunga ki te mātakitaki i te kaha o ngā maramara i hangaia i te motu.
I te ahiahi o te whakaaturanga, i manaaki te tūru o YMIN i tētahi tira tohunga rongonui hei whakawhitiwhiti kōrero. I whakaatu te tira, tae atu ki tētahi tohunga mātauranga o te Virginia Tech Academy, te kaiwhakahaere R&D o Delta Electronics, me ngā ahorangi mai i te Whare Wānanga o Shanghai Maritime, te Whare Wānanga o Zhejiang, me te Whare Wānanga o Xi'an Jiaotong, i te hiahia nui ki ngā whakatutukitanga hangarau a YMIN i tā rātou haerenga mai. I tino miharo ngā tohunga ki te whakamahinga auaha o te whakatupuranga hou o ngā supercapacitors lithium-ion (LIC) a YMIN i roto i te pūtake hiko tārua o te tūmau AI NVIDIA GB300 BBU. Ka aro tika tēnei otinga ki ngā wero o ngā ngaru hiko GPU me te roa o te pāmahana teitei, ka tutuki he whakaiti nui i te rahi me te taumaha me te tautoko i te mana tihi o te 15–21kW me te mahi tae atu ki te ātete ā-roto <1mΩ, te utu tere 10-meneti, me te 1 miriona huringa. I whakaatuhia hoki te YMIN i whakawhanakehia motuhaketia.Ngā pūnga haona wai raupapa IDC3i hangaia mō ngā pūhiko tūmau AI mana-teitei. Ko ēnei pūnga iahiko, ko te nuinga he 450V 1400μF me te 30×70mm te rahi, he nui ake te ātete ngaohiko, he nui ake te kiato capacitance, me te roa ake o te ora, e whakarato ana i te tautoko nui mō te whakapai ake i te kiato mana me te pono o ngā pūhiko tūmau AI. Ko te mōhio me te aro mai o ēnei tohunga matua te tohu pai rawa atu o te whakapau kaha a YMIN ki te auahatanga motuhake me āna mahi ki te aro atu ki ngā tono teitei.
Te Tūnga o YMIN: Ngā Whakamahinga Pūnga – Mō ō Wero Katoa, Tahuri ki a YMIN
Ehara i te mea he kaihanga pūngao noa iho mātou; e whakapau kaha ana mātou ki te noho hei kaiārahi ā-rohe e kaha ana ki te whakakapi i ngā waitohu o te ao. I roto i ngā mara pēnei i ngā waka hiko hou, ngā tūmau AI, te rokiroki hiko photovoltaic, me ngā puku ahumahi, ka whakaratohia e mātou ki ngā kiritaki he otinga pūngao e tuku ana i te pai ake o te mahi, te kiato hiko teitei ake, me te pono teitei ake.
