LIBETIRI TSA AI / LIPHEBELO TSA MATLA
Navitas Semiconductor e entse moralo oa litšupiso oa 3.2kW bakeng sa lisebelisoa tsa motlakase tse thehiloeng ho GaN bakeng sa likarete tsa accelerator tsa AI litsing tsa data.
Moralo oa litšupiso tsa seva oa CRPS185 3 Titanium Plus o tsoang Navitas o feta litlhoko tse thata tsa 80Plus Titanium ho fihlela litlhoko tse ntseng li eketseha tsa matla a setsi sa data sa AI.
Li-processor tsa AI tse lapetseng matla joalo ka Nvidia's DGX GH200 'Grace Hopper' li batla ho fihla ho 1,600 W ka 'ngoe, li khanna lintlha tsa motlakase ho tloha ho 30-40 kW ho isa ho 100 kW ka khabinete ka 'ngoe.Ho sa le joalo, ka sepheo sa lefats'e sa ho boloka matla le phokotso ea tlhahiso, hammoho le melaoana ea morao-rao ea Europe, phepelo ea motlakase ea li-server e tlameha ho feta 80Plus 'Titanium' e boletsoeng hantle.
● Borokho ba GaN halofo bo kopantsoe ka har'a sephutheloana se le seng
● Moloko oa boraro oa matla a GaN IC
Meralo ea litšupiso tsa Navitas e fokotsa nako ea nts'etsopele mme e nolofalletsa matla a phahameng a matla, matla a matla le litšenyehelo tsa tsamaiso ho sebelisa li-IC tsa matla a GaNFast.Li-platform tsena tsa sistimi li kenyelletsa tebeletso e felletseng ea meralo e nang le lisebelisoa tse lekiloeng ka botlalo, software e kentsoeng, meralo, thepa ea thepa, moralo, ketsiso le liphetho tsa liteko tsa Hardware.
CRPS185 e sebelisa meralo ea morao-rao ea potoloho e kenyelletsang totem-pole PFC ea CCM e nang le borokho bo felletseng LLC.Likarolo tsa bohlokoa ke li-IC tsa Navitas tsa 650V GaNFast tse ncha, tse nang le koloi e matla, e lebelo le holimo ea GaN ho sebetsana le litaba tsa kutlo le bofokoli tse amanang le li-chips tsa GaN tse hlakileng.
Li-IC tsa matla a GaNFast li boetse li fana ka tahlehelo e tlase haholo ea ho fetoha, e nang le matla a nakoana-voltage ho fihla ho 800 V, le melemo e meng ea lebelo le phahameng joalo ka theko e tlase ea heke (Qg), capacitance ea tlhahiso (COSS) mme ha ho tahlehelo ea ho khutlisa (Qrr). ).Ha ho fetoha ka lebelo le phahameng ho fokotsa boholo, boima le litšenyehelo tsa likarolo tse sa sebetseng phepelong ea motlakase, Navitas e hakanya hore li-IC tsa motlakase tsa GaNFast li boloka 5% ea litšenyehelo tsa lisebelisoa tsa sistimi ea LLC-stage, hammoho le $64 ka phepelo ea motlakase ka lilemo tse 3.
Moralo ona o sebelisa sebopeho sa 'Common Redundant Power Supply' (CRPS) se hlalosoang ke Hyperscale Open Compute Project, ho kenyeletsoa Facebook, Intel, Google, Microsoft, le Dell.
● Setsi sa meralo ea Chaena bakeng sa setsi sa data GaN
● Phepelo ea 2400W CPRS AC-DC e na le katleho ea 96%.
U sebelisa CPRS, sethala sa CRPS185 se fana ka matla a 3,200 W ka botlalo ka 1U (40 mm) x 73.5mm x 185 mm (544 cc), ho fihlela 5.9 W/cc, kapa hoo e ka bang 100 W/in3 matla a matla.Ena ke phokotso ea boholo ba 40% khahlano le, mokhoa o lekanang oa silicon oa lefa mme o feta habonolo maemo a ts'ebetso ea Titanium, o fihla ho feta 96.5% ho 30% mojaro, le ho feta 96% ho tloha ho 20% ho isa ho 60% mojaro.
Ha ho bapisoa le litharollo tsa setso tsa 'Titanium', moralo oa Navitas CRPS185 3,200 W 'Titanium Plus' o sebetsang ka mojaro o tloaelehileng oa 30% o ka fokotsa tšebeliso ea motlakase ka 757 kWh, 'me oa fokotsa tlhahiso ea carbon dioxide ka lik'hilograma tse 755 ka lilemo tse 3.Phokotso ena e lekana le ho boloka 303 kg ea mashala.Ha e thuse feela bareki ba setsi sa data ho fumana chelete ea ho boloka litšenyehelo le ntlafatso ea katleho, empa hape e kenya letsoho lipakaneng tsa tikoloho tsa ho boloka matla le ho fokotsa mocheso.
Ntle le li-server tsa setsi sa data, moralo oa litšupiso o ka sebelisoa lits'ebetsong tse joalo ka phepelo ea motlakase ea switch / router, likhokahano le lits'ebetso tse ling tsa komporo.
"Ho tuma ha lits'ebetso tsa AI joalo ka ChatGPT ke qalo feela.Ha matla a setsi sa data a ntse a eketseha ka 2x-3x, ho fihla ho 100 kW, ho fana ka matla a mangata sebakeng se senyenyane ke ntho ea bohlokoa, "ho boletse Charles Zha, VP le GM oa Navitas China.
"Re mema baqapi ba matla le baetsi ba meralo ea meralo ho sebelisana le Navitas le ho fumana hore na 'mapa o felletseng oa ts'ebetso e phahameng, meralo e matla ea matla a phahameng e ka bitsa chelete e ngata,' me ea potlakisa ntlafatso ea bona ea seva ea AI."
