Yuav ua li cas tuaj yeem ua kom muaj kev txhim kho tus nqi - ua tiav ntawm cov khoom sib txuas lus?

1, Cov Khoom Siv Khoom Siv Khoom Siv: Rov Kho Zog Hluav Taws Xob Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob dav nrog cov khoom siv bandgap
Cov kev txwv kev ua tau zoo ntawm kev tsoos silicon - kev ntsuas dua tshiab, thiab cov xwm txheej kub siab, thiab kub siab (Si) thiab galos Nqa lub zog module ntawm 5G lub hauv paus pib ua ib qho piv txwv, los hloov cov khoom siv hluav taws xob dices nrog 0.7v rau 0.3v, thiab kev poob rau hauv lub raj yog txo los ntawm 4W ntawm 10a tam sim no. Ua ke nrog synchron lub sij hawm thev naus laus zis, lub zog hluav taws xob tau ntau dua 96%. Raws li cov ntaub ntawv ntsuas tiag tiag los ntawm ib tus neeg teb xov tooj, siv cov khoom sib txuas lus ntawm 48V / 12V sib txuas lus fais fab muaj peev xwm txuag tau ntau dua 120000 yuan hauv kev siv hluav taws xob feem ntau. Nyob rau tib lub sijhawm, vim 40℃txo hauv qhov kub thiab txias, lub neej module tau txuas ntxiv los ntawm peb zaug, thiab cov nqi txij nkawm yog txo los ntawm 60%.
Nyob rau hauv teb rf pem hauv ntej -}}}}}}}} electr electr electr electr້ increase electr້ນ} 4 4 trans້ນ 4 4 trans້ນ ntxiv rau hauv lub hau hluav taws xob nce ntxiv nyob rau hauv daim duab tsis pub dhau 3.5dB. Tom qab tau txais cov thev naus laus zis hauv ib hom 64T64r loj heev Mimo qhov chaw nres tsheb loj yog nce los ntawm 8%, ua qauv pom zoo them tus nqi tseem ceeb.
2, Circcuit Coedtracter: Kev sib faib hauv synchron rectification thiab cov peev txheej tsim nyog thev naus laus zis
Lub ntsuas hluav taws xob ruaj khov poob poob ntawm cov tsoos Dioode Rectifier ncig yog tau dhau los ntawm synchron rectification technology. Los ntawm kev hloov cov diodes nrog mosfets thiab sib txuas nrog cov duab kos duab kos duab, kev hloov kho tsis sib haum xeeb ntawm kev tiv taus<5m Ω can be achieved. A certain type of AI server power supply adopts a synchronous rectification scheme controlled by LTC4359, with a voltage drop of only 56mV at 3A current and a full load efficiency of 98.5%, which is 6 percentage points higher than the traditional silicon diode scheme. More importantly, this technology reduces the size of power modules by 40%, creating conditions for increasing the density of data center cabinets. The computing power density of a single cabinet exceeds 50PFLOPS, and the unit computing power consumption is reduced to 0.1W/GFLOPS.
Hauv kev hloov pauv kev hloov pauv tshiab, qhov ntsuas kub txav teeb meem ntawm diode voltage poob yog tshem tawm los ntawm kev them nyiaj ntse. Ib hom submarine fiber ntau optic cable kev rov ua dua tshiab ntawm408 sensor resistor network, uas ua rau cov bias voltage ntawm lub photodiode (pd) hloov kho<0.05V within the temperature range of -40 ℃ to+85 ℃, and improves the stability of the receiving sensitivity by 0.3dB. This improvement extends the repeater spacing from 80km to 100km, reduces the number of repeaters for a single transoceanic fiber optic cable by 20%, and reduces the construction cost by 120 million US dollars per thousand kilometers.
3, System Kev Sib Tw Kev Koom Tes: faib cov architecture thiab digital ntxig kev ua kom zoo
Lub zog hluav taws xob ntawm cov ntaub ntawv cov ntaub ntawv loj yog hloov zuj zus los ntawm qhov chaw nres tsheb kom faib cov kev txhim kho. Lub npav 48V DC yog tsim los ua ke nrog faib hluav taws xob muab cov qauv (PSU) coj cov rectification txuas ze rau cov khoom thauj khoom. Tom qab mus kawm cov archivpececture no, qee hom kev sib kis supercomputer uas raug rho tawm ntawm 95%, thiab cov ntsiab lus sib nrug ntau dua cov tsoos 400v ac accontacture. Ntau tus neeg tseem ceeb tshaj plaws yog tias cov architecture uas tau muab faib rau PSU tshiab los yog hloov sijhawm los ntawm cov sij hawm mus rau feeb thiab txuag Yuan nyob rau hauv cov nqi kho txhua xyoo.
Cov thev naus laus thev naus laus zis yog kho cov txheej txheem ntawm Diode xaiv. Lub adi ltspice simulation platform ua ke nrog LSTM Network network algorithm tuaj yeem twv kev faib cov diode poob raws li kev ua haujlwm sib txawv. Lub hwj chim tsim ntawm qee hom 5G lub chaw nres tsheb ua haujlwm xaiv cov khoom siv ntawm cov thev naus laus zis ntawm cov thev naus laus zis ntawm cov thev naus laus zis txhua xyoo dhau los Nyob rau hauv teb ntawm photveroltaic inverters, digital ntxaib thev naus laus zis ntawm Rc defitive network tsis tau los ntawm lub lis piam mus rau teev, thiab txhim kho kev txhim kho ntawm 80%.
