AI BATTERIES / INGUFU Z'UBUBASHA
Navitas Semiconductor yateguye igishushanyo mbonera cya 3.2kW kubikoresho bya GaN bitanga amashanyarazi kubikarita yihuta ya AI mubigo byamakuru.
CRPS185 3 Titanium Plus ya seriveri yerekanwe muri Navitas irenze ibisabwa 80Plus Titanium ikora neza kugirango ihuze ingufu zikenerwa nimbaraga za AI data center.
Imashanyarazi ya AI ifite ingufu nka DGX GH200 ya Nvidia 'Grace Hopper' isaba kugeza kuri 1,600 W imwe, itwara ingufu kuri buri rack kuva kuri 30-40 kW kugeza kuri 100 kW kuri buri kabari.Hagati aho, hamwe n’isi yose yibanda ku kubungabunga ingufu no kugabanya ibyuka bihumanya ikirere, kimwe n’amabwiriza aheruka y’iburayi, ibikoresho bya seriveri bigomba kurenga 80Plus 'Titanium' ikora neza.
● GaN igice cyikiraro cyinjijwe muri paki imwe
Generation Igisekuru cya gatatu GaN power IC
Ibishushanyo mbonera bya Navitas bigabanya igihe cyiterambere kandi bigafasha ingufu zingirakamaro, ubwinshi bwingufu nigiciro cya sisitemu ukoresheje ingufu za GaNFast.Izi porogaramu zirimo sisitemu yuzuye ingwate hamwe nibikoresho byageragejwe byuzuye, software yashyizwemo, ibishushanyo, fagitire y'ibikoresho, imiterere, kwigana n'ibisubizo by'ibizamini.
CRPS185 ikoresha ibishushanyo mbonera byumuzingi bigezweho birimo CCM totem-pole PFC ifatanye hamwe nikiraro cyuzuye LLC.Ibice byingenzi ni Navitas nshya ya 650V ya GaNFast yamashanyarazi, hamwe na disiki ikomeye, yihuta yihuta ya GaN kugirango ikemure ibibazo byunvikana kandi byoroshye bifitanye isano na chip ya GaN yihariye.
Imbaraga za GaNFast nazo zitanga igihombo gito cyane cyo guhinduranya, hamwe nubushobozi bwigihe gito-voltage igera kuri 800 V, nibindi byiza byihuta cyane nko kwishyurwa amarembo make (Qg), ubushobozi bwo gusohora (COSS) kandi nta gihombo gisubirana (Qrr) ).Nkuko guhinduranya byihuse bigabanya ingano, uburemere nigiciro cyibikoresho bya pasiporo mugutanga amashanyarazi, Navitas ivuga ko ingufu za GaNFast ICs zizigama 5% yikiguzi cya sisitemu ya LLC, hiyongereyeho $ 64 kumashanyarazi mumashanyarazi mumyaka 3.
Igishushanyo gikoresha 'Common Redundant Power Supply' (CRPS) imiterere-yibintu bisobanurwa na hyperscale Open Compute Project, harimo Facebook, Intel, Google, Microsoft, na Dell.
Center Ubushinwa bushushanya ikigo cya GaN
00 2400W CPRS AC-DC itanga ifite 96% ikora neza
Ukoresheje CPRS, urubuga rwa CRPS185 rutanga W 3,200 W yuzuye yuzuye muri 1U (40 mm) x 73.5mm x 185 mm (544 cc), igera kuri 5.9 W / cc, cyangwa hafi 100 W / in3.Nubunini bwa 40% kugabanya vs, uburyo bwa silicon ihwanye nuburyo bworoshye kandi burenze byoroshye igipimo cyiza cya Titanium, kigera kuri 96.5% kumitwaro 30%, naho hejuru ya 96% kuva kuri 20% kugeza kuri 60%.
Ugereranije n’ibisubizo gakondo bya 'Titanium', igishushanyo cya Navitas CRPS185 3,200 W 'Titanium Plus' ikora ku mutwaro usanzwe wa 30% irashobora kugabanya ikoreshwa ry’amashanyarazi kuri kilowati 757, kandi ikagabanya imyuka ya karuboni 755 kg mu myaka 3.Uku kugabanuka guhwanye no kuzigama kg 303 yamakara.Ntabwo ifasha gusa abakiriya ba data center kugera ku kuzigama no kuzamura imikorere, ahubwo inagira uruhare mu ntego z’ibidukikije zo kubungabunga ingufu no kugabanya ibyuka bihumanya.
Usibye amakuru yikigo cya seriveri, igishushanyo mbonera gishobora gukoreshwa mubisabwa nka switch / router itanga ibikoresho, itumanaho, nibindi bikorwa byo kubara.
“Kwamamara kwa porogaramu za AI nka ChatGPT ni intangiriro.Kubera ko amakuru y’ikigo yiyongera kuri 2x-3x, agera kuri kilo 100, gutanga ingufu nyinshi mu mwanya muto ni ingenzi, ”ibi bikaba byavuzwe na Charles Zha, VP na GM wa Navitas China.
Ati: "Turahamagarira abashinzwe amashanyarazi n'abubatsi ba sisitemu gufatanya na Navitas no kuvumbura uburyo igishushanyo mbonera cyuzuye cyo gukora neza, ibishushanyo mbonera by’amashanyarazi bishobora kugiciro cyinshi, kandi byihutisha iterambere rya seriveri ya AI."
