Navitas Semiconductor tau tsim 3.2kW siv tsim rau GaN-raws li cov khoom siv hluav taws xob rau AI accelerator phaib hauv cov ntaub ntawv chaw.

CRPS185 3 Titanium Plus neeg rau zaub mov siv tsim los ntawm Navitas tshaj qhov nruj 80Plus Titanium kev ua haujlwm kom tau raws li qhov xav tau ntawm lub zog ntawm AI cov ntaub ntawv chaw lub zog.
Lub zog-tshaib plab AI processors zoo li Nvidia's DGX GH200 'Grace Hopper' xav tau txog 1,600 W txhua, tab tom tsav lub zog-ib-rack specifications los ntawm 30-40 kW mus txog 100 kW ib lub txee.Lub caij no, nrog rau lub ntiaj teb tsom mus rau kev txuag hluav taws xob thiab kev txo qis, nrog rau cov kev cai European tshiab, cov khoom siv hluav taws xob rau cov neeg siv khoom yuav tsum tshaj 80Plus 'Titanium' efficiency specification.

● GaN ib nrab choj txuas rau hauv ib pob
● Peb tiam GaN fais fab IC

Navitas siv cov qauv tsim txo lub sijhawm txhim kho thiab ua kom muaj zog ntau dua, lub zog ceev thiab cov nqi siv hluav taws xob siv GaNFast ICs.Cov txheej txheem txheej txheem no suav nrog kev tsim cov khoom lag luam ua tiav nrog cov khoom lag luam kuaj tag nrho, kos software, schematics, daim nqi ntawm cov ntaub ntawv, layout, simulation thiab cov txiaj ntsig kuaj kho vajtse.

CRPS185 siv cov qauv tsim hluav taws xob tshiab suav nrog kev sib cuam tshuam CCM totem-ncej PFC nrog tag nrho-bridge LLC.Cov khoom tseem ceeb yog Navitas 'tshiab 650V GaNFast fais fab ICs, nrog lub zog, kev kub ceev sib xyaw GaN tsav los daws qhov teeb meem rhiab heev thiab fragility cuam tshuam nrog discrete GaN chips.
Lub GaNFast fais fab ICs kuj muaj qhov tsis tshua muaj kev hloov pauv, nrog lub peev xwm hloov pauv-voltage mus txog 800 V, thiab lwm yam kev ua haujlwm siab zoo xws li cov rooj vag qis (Qg), tso zis hluav taws xob (COSS) thiab tsis rov qab poob (Qrr. ).Raws li kev hloov pauv ceev txo qhov loj, qhov hnyav thiab tus nqi ntawm cov khoom siv hluav taws xob tsis zoo, Navitas kwv yees tias GaNFast lub zog ICs txuag 5% ntawm LLC-theem cov khoom siv tus nqi, ntxiv rau $ 64 ib lub zog hluav taws xob hauv hluav taws xob ntau dua 3 xyoos.

Tus tsim siv 'Common Redundant Power Supply' (CRPS) daim ntawv qhia tshwj xeeb uas txhais los ntawm hyperscale Open Compute Project, suav nrog Facebook, Intel, Google, Microsoft, thiab Dell.

● Tuam Tshoj tsim chaw rau cov ntaub ntawv chaw GaN
● 2400W CPRS AC-DC mov muaj 96% efficiency

Siv CPRS, CRPS185 platform muab tag nrho 3,200 W ntawm lub zog hauv tsuas yog 1U (40 mm) x 73.5mm x 185 mm (544 cc), ua tiav 5.9 W / cc, lossis yuav luag 100 W / in3 lub zog ntom ntom.Qhov no yog 40% txo qhov me me vs, qhov sib npaug ntawm cov cuab yeej cuab tam silicon thiab yooj yim tshaj li Titanium efficiency tus qauv, ncav tshaj 96.5% ntawm 30% load, thiab tshaj 96% stretching ntawm 20% mus rau 60% load.

Piv nrog rau cov kev daws teeb meem 'Titanium' ib txwm muaj, Navitas CRPS185 3,200 W 'Titanium Plus' tsim khiav ntawm 30% kev thauj khoom tuaj yeem txo cov hluav taws xob siv los ntawm 757 kWh, thiab txo cov pa roj carbon dioxide 755 kg hauv 3 xyoos.Qhov kev txo qis no yog sib npaug rau kev txuag 303 kg ntawm cov thee.Nws tsis tsuas yog pab cov neeg siv ntaub ntawv hauv chaw ua haujlwm kom tau txais kev txuag nqi thiab kev txhim kho kev ua haujlwm, tab sis nws kuj tseem ua rau lub hom phiaj ntawm kev txuag hluav taws xob thiab txo qis emissions.

Ntxiv nrog rau cov chaw zov me nyuam cov ntaub ntawv, cov qauv siv tau siv tau rau hauv cov ntawv thov xws li hloov / router fais fab mov, kev sib txuas lus, thiab lwm yam kev siv computer.

"Qhov nrov ntawm AI daim ntawv thov xws li ChatGPT yog qhov pib xwb.Raws li cov ntaub ntawv chaw khib fais fab nce 2x-3x, mus txog 100 kW, xa ntau lub zog hauv qhov chaw me me yog qhov tseem ceeb, "said Charles Zha, VP thiab GM ntawm Navitas Tuam Tshoj.

"Peb caw cov kws tsim hluav taws xob thiab cov kws tsim qauv tsim qauv los koom tes nrog Navitas thiab tshawb pom yuav ua li cas cov phiaj xwm ua tiav ntawm kev ua haujlwm siab, kev tsim hluav taws xob muaj zog tuaj yeem raug nqi zoo, thiab txhawb nqa lawv cov kev hloov kho AI server."
