Cov racks AI server muaj kev cuam tshuam los ntawm millisecond-level (feem ntau yog 1–50 ms) lub zog nce thiab DC bus voltage poob thaum lub sijhawm hloov pauv sai ntawm kev cob qhia thiab kev xav. NVIDIA, hauv nws qhov GB300 NVL72 power rack tsim, hais tias nws lub power rack sib xyaw cov khoom siv khaws cia lub zog thiab ua haujlwm nrog tus maub los kom ua tiav rack-level quick transient power smoothing (saib qhov siv [1]).
Hauv kev xyaum ua haujlwm engineering, siv "hybrid supercapacitor (LIC) + BBU (Battery Backup Unit)" los tsim ib txheej buffer nyob ze tuaj yeem txiav tawm "transient response" thiab "short-term backup power": LIC yog lub luag haujlwm rau millisecond-level compensation, thiab BBU yog lub luag haujlwm rau qib thib ob mus rau feeb takeover. Tsab xov xwm no muab ib txoj hauv kev xaiv rov ua dua rau cov engineers, ib daim ntawv teev cov cim tseem ceeb, thiab cov khoom pov thawj. Siv YMIN SLF 4.0V 4500F (ib chav ESR≤0.8mΩ, continuous discharge current 200A, parameters yuav tsum xa mus rau daim ntawv specification [3]) ua piv txwv, nws muab cov lus qhia txog kev teeb tsa thiab kev txhawb nqa cov ntaub ntawv sib piv.
Cov khoom siv fais fab ntawm Rack BBU tab tom txav "kev ua kom lub zog hloov pauv ib ntus" ze rau qhov thauj khoom.
Thaum lub zog siv ib lub khib nce mus txog ntau pua kilowatts, AI workloads tuaj yeem ua rau tam sim no nce siab hauv lub sijhawm luv luv. Yog tias qhov voltage poob qis tshaj qhov system threshold, nws yuav ua rau muaj kev tiv thaiv motherboard, GPU yuam kev, lossis rov pib dua. Txhawm rau kom txo qhov cuam tshuam siab tshaj plaws ntawm kev muab hluav taws xob upstream thiab lub grid, qee cov architectures tab tom qhia txog kev tiv thaiv lub zog thiab kev tswj hwm hauv lub khib fais fab, tso cai rau lub zog nce siab kom "nqus thiab tso tawm hauv zos" hauv lub khib. Cov lus tseem ceeb ntawm qhov kev tsim no yog: cov teeb meem transient yuav tsum tau daws ua ntej ntawm qhov chaw ze tshaj plaws rau qhov load.
Hauv cov servers uas muaj ultra-high-power (kilowatt-level) GPUs xws li NVIDIA GB200/GB300, qhov teeb meem tseem ceeb uas cov tshuab fais fab ntsib tau hloov ntawm lub zog thaub qab ib txwm mus rau kev tswj hwm lub zog hloov pauv ntawm millisecond thiab pua pua kilowatt. Cov kev daws teeb meem fais fab thaub qab BBU ib txwm muaj, uas tsom mus rau cov roj teeb lead-acid, raug kev txom nyem los ntawm kev teb ceev thiab lub zog ceev vim yog kev ncua sijhawm ntawm cov tshuaj lom neeg, kev tiv thaiv sab hauv siab, thiab kev lees txais lub zog dynamic tsawg. Cov teeb meem no tau dhau los ua cov yam tseem ceeb uas txwv tsis pub txhim kho lub zog xam ib-rack thiab kev ntseeg siab ntawm lub system.
Rooj 1: Daim duab qhia txog qhov chaw ntawm hom kev khaws cia zog peb theem hauv lub khib BBU (daim duab rooj)
| Sab Thauj Khoom | DC Tsheb Npav | LIC (Hybrid Super Capacitor) | BBU (Roj Teeb/Cia Khoom Siv Hluav Taws Xob) | UPS/HVDC |
| Kauj Ruam Fais Fab GPU/Motherboard (ms Qib) | DC Bus Voltage Voltage Drop/Ripple | Kev Them Nyiaj Hauv Zos Feem Ntau 1-50 ms Tus Nqi Them / Tshem Tawm Tus Nqi Siab | Kev Tswj Xyuas Lub Sijhawm Luv Luv Qib Thib Ob-Feeb (Tsim Raws Li Lub Txheej Txheem) | Lub Hwj Chim Siv Tau Ntev Feeb-Teev (Raws li Data Center Architecture) |
Kev Hloov Pauv ntawm Kev Tsim Kho Vaj Tse
Los ntawm "Roj Teeb Tseg" mus rau "Hom Cia Khoom Siv Hluav Taws Xob Peb-Tier Hybrid"
Cov BBU ib txwm siv roj teeb los khaws cia lub zog. Vim muaj teeb meem tsis txaus fais fab hauv millisecond, cov roj teeb, uas raug txwv los ntawm kev ua haujlwm ntawm cov tshuaj lom neeg thiab kev tiv thaiv sab hauv, feem ntau teb tsis tau sai dua li kev khaws cia lub zog siv capacitor. Yog li ntawd, cov kev daws teeb meem ntawm rack-side tau pib siv txoj kev npaj sib txawv: "LIC (transient) + BBU (short-time) + UPS/HVDC (long-time)":
LIC txuas nrog parallel ze ntawm DC Bus: tswj hwm millisecond-level fais fab kev them nyiaj thiab kev txhawb nqa voltage (kev them thiab tso tawm sai).
BBU (roj teeb lossis lwm yam kev khaws cia zog): tswj hwm qib thib ob mus rau feeb (lub kaw lus tsim los rau lub sijhawm thaub qab).
UPS/HVDC theem chaw khaws ntaub ntawv: tswj kev muab hluav taws xob tsis tu ncua mus sij hawm ntev thiab kev tswj hwm sab grid.
Qhov kev faib ua haujlwm no cais cov "cov hloov pauv sai" thiab "cov hloov pauv qeeb": ua kom lub tsheb npav ruaj khov thaum txo cov kev ntxhov siab mus sij hawm ntev thiab kev saib xyuas ntawm cov chaw khaws cia hluav taws xob.
Kev Tshawb Fawb tob tob: Vim li cas YMINCov Supercapacitors Sib Xyaws?
ymin lub hybrid supercapacitor LIC (Lithium-ion Capacitor) sib xyaw ua ke cov yam ntxwv muaj zog siab ntawm cov capacitors nrog lub zog siab ntawm lub tshuab hluav taws xob. Hauv cov xwm txheej them nyiaj ib ntus, qhov tseem ceeb rau kev tiv taus lub nra hnyav yog: tso tawm lub zog xav tau hauv lub hom phiaj Δt, thiab xa cov hluav taws xob loj txaus hauv qhov kub thiab txias thiab qhov poob qis.
Lub Zog Muaj Zog: Thaum GPU hloov pauv sai sai lossis lub zog hluav taws xob hloov pauv, cov roj teeb lead-acid ib txwm muaj, vim lawv cov tshuaj lom neeg qeeb qeeb thiab kev tiv thaiv sab hauv siab, muaj kev puas tsuaj sai sai hauv lawv lub peev xwm lees txais lub zog, ua rau tsis muaj peev xwm teb hauv milliseconds. Lub hybrid supercapacitor tuaj yeem ua tiav kev them nyiaj tam sim ntawd hauv 1-50ms, ua raws li lub zog thaub qab ntawm BBU thaub qab fais fab mov, ua kom lub zog tsheb npav ruaj khov thiab txo qhov kev pheej hmoo ntawm motherboard thiab GPU sib tsoo.
Kev Txhim Kho Qhov Ntim thiab Qhov Hnyav: Thaum piv "lub zog sib npaug muaj (txiav txim siab los ntawm lub qhov rais V_hi → V_lo voltage) + lub qhov rais sib npaug transient (Δt)," LIC buffer txheej kev daws teeb meem feem ntau txo qhov ntim thiab qhov hnyav piv rau cov roj teeb thaub qab ib txwm muaj (kev txo qhov ntim ntawm kwv yees li 50% -70%, kev txo qhov hnyav ntawm kwv yees li 50% -60%, cov nqi ib txwm tsis muaj rau pej xeem thiab xav tau kev txheeb xyuas qhov project), tso qhov chaw khib thiab cov peev txheej cua. (Qhov feem pua tshwj xeeb nyob ntawm cov lus qhia, cov khoom siv, thiab cov kev daws teeb meem cua sov ntawm cov khoom sib piv; kev txheeb xyuas tshwj xeeb rau qhov project yog qhov pom zoo.)
Kev Txhim Kho Ceev Them: LIC muaj peev xwm them thiab tso tawm sai, thiab nws qhov ceev them rov qab feem ntau siab dua li ntawm cov roj teeb daws teeb meem (kev txhim kho ceev ntau dua 5 zaug, ua tiav ze li kaum feeb them ceev; qhov chaw: hybrid supercapacitor piv rau cov nqi roj teeb lead-acid ib txwm muaj). Lub sijhawm them rov qab yog txiav txim siab los ntawm lub zog ntawm lub kaw lus, txoj kev them nqi, thiab kev tsim thermal. Nws raug pom zoo kom siv "lub sijhawm xav tau los them rov qab rau V_hi" ua qhov kev lees txais, ua ke nrog kev ntsuas qhov kub thiab txias rov ua dua.
Lub neej voj voog ntev: LIC feem ntau qhia txog lub neej voj voog ntev dua thiab qis dua qhov yuav tsum tau saib xyuas nyob rau hauv cov xwm txheej them thiab tso tawm ntau zaus (1 lab lub voj voog, ntau tshaj 6 xyoo ntawm lub neej, kwv yees li 200 npaug ntawm cov roj teeb lead-acid ib txwm muaj; qhov chaw: Hybrid supercapacitors piv rau cov roj teeb lead-acid ib txwm muaj). Lub neej voj voog thiab qhov kub nce siab yog nyob ntawm cov lus qhia tshwj xeeb thiab cov xwm txheej sim. Los ntawm lub neej voj voog tag nrho, qhov no pab txo cov nqi ua haujlwm thiab kev saib xyuas thiab kev ua tsis tiav.
Daim Duab 2: Daim Duab Qhia Txog Lub Tshuab Khaws Cia Hluav Taws Xob Sib Xyaws:
Roj teeb Lithium-ion (theem ob feeb) + Lithium-ion Capacitor LIC (theem millisecond buffer)
Raws li NVIDIA GB300 tus qauv siv los ntawm Nyiv Musashi CCP3300SC (3.8V 3000F), nws muaj peev xwm ntau dua, muaj hluav taws xob ntau dua, thiab muaj peev xwm ntau dua hauv nws cov lus qhia rau pej xeem: lub zog ua haujlwm 4.0V thiab lub peev xwm 4500F, ua rau muaj kev khaws cia hluav taws xob ib lub cell ntau dua thiab muaj peev xwm ua kom muaj zog dua hauv tib qhov loj me ntawm module, ua kom ntseeg tau tias muaj kev teb tsis muaj teeb meem millisecond.
