Gukuraho ikibazo cy’amashanyarazi kuri CPU/GPU za AI Server: Nigute wakwita ku mihindagurikire y’amashanyarazi y’igihe gito ya Nanosecond? Nigute washungura urusaku rwa MHz?

Incamake: Ukwiyongera kwihuta kw'ingufu za mudasobwa za chips za AI biri gutuma imiyoboro yazo y'amashanyarazi igera ku mupaka wayo. Umuvuduko w'amashanyarazi ugabanuka ukagera kuri 0.8-1.2V, kandi kwiyongera k'umuvuduko w'amashanyarazi mu cyiciro kimwe kugera ku ma ampeta amagana, bigatuma habaho icyuho cy'umuvuduko w'amashanyarazi mu rwego rwa nanosecond (10-100ns) n'urusaku rw'amashanyarazi mu rwego rwa MHz ku musaruro wa VRM. Capacitors gakondo, bitewe n'uko zifite ESR nyinshi n'impedance nini ya frequency, zabaye imbogamizi ku buryo sisitemu ihamye, mu gihe ibisubizo mpuzamahanga by'urwego rwo hejuru biteza ibyago ku ruhererekane rw'amashanyarazi. Iyi nkuru isesengura ibipimo bitatu by'ingenzi by'umusozo w'amashanyarazi kandi ikoresha amakuru yapimwe yavuye muri YMIN MPS series ultra-low ESR multilayer solid capacitors (conductive polymer chip aluminum electrolytic capacitors) nk'urugero rwo guha injeniyeri inzira yo gusimbuza amashanyarazi ijyanye n'ibipimo mpuzamahanga by'imikorere kandi ifite umuyoboro w'amashanyarazi wigenga kandi ushobora kugenzurwa.

Intangiriro: "Umurinzi utagaragara" w'Umuyoboro w'Amashanyarazi arimo gusobanurwa bundi bushya

Kuri seriveri za AI zikurikirana imbaraga za mudasobwa zihambaye, ubunyangamugayo bw'amashanyarazi (PI) ni ryo shingiro ry'ubudahangarwa. Ubwiyongere bw'umutwaro wa CPU/GPU ku rwego rwa nanosecond ni nk' "inkubi z'umuyaga zigezweho." Iyo capacitor ya VRM idashobora kongera ingufu vuba mu gihe cy'idirishya rya nanosecond ridafite umurongo mbere y'uko umurongo ugenzura usubiza (microsegonda), bizatuma voltage y'ibanze igabanuka, bigatera amakosa yo kubara cyangwa kugabanya inshuro. Muri icyo gihe, niba urusaku rwo guhindura MHz rudashyizwemo, ruzabangamira ibimenyetso by'umuvuduko mwinshi. Kubwibyo, capacitor yavuye ku "gushungura by'ibanze" ijya ku buffer ya nyuma yo kubika ingufu n'umuyoboro wo gusohora urusaku kugira ngo "uburinzi bukwiye."

Ibipimo bitatu by'ingenzi: Kuki ibisubizo gakondo bitagenda neza?

Inkunga y'igihe gito ku rwego rwa Nanosecond: ESR niyo mpamvu ikomeye. Umuvuduko w'igisubizo uterwa n'ubudahangarwa bw'imbere; ESR iri hasi cyane ya ≤3mΩ ni urugero rukomeye rwo kugera ku irekurwa ryihuse ry'umushari wo ku rwego rwa nanosecond.

Kugabanya urusaku ku rwego rwa MHz: Ibiranga impedance y'umuvuduko mwinshi ni ingenzi. Capacitor igomba kugira impedance nke cyane ku murongo wa switching na harmonics zayo kugira ngo itange inzira nziza yo kugera ku butaka kugira ngo urusaku rugere ku butaka, bityo habeho ubusugire bw'ibimenyetso bya PCIe/DDR.

Ubushyuhe bwinshi n'igihe kirekire cyo kubaho: Guhuza imikorere mibi ya 7x24h y'amakuru. Ubuzima bw'amasaha 2000 kuri 105℃ n'ubushobozi bwo kuzenguruka cyane (>10A) ni ingenzi mu guhangana n'ubushyuhe bwinshi bw'igihe kirekire no kugabanya ikiguzi cyo gukoresha no kubungabunga.

Ishyirwa mu bikorwa ry'igisubizo: YMINUrukurikirane rwa MPS– Amahitamo yo mu gihugu afite agaciro gakomeye anyuranyije n'amahame mpuzamahanga

Uruhererekane rwa YMIN MPS ruvuga ku buryo butaziguye ku ngingo zibabaje zavuzwe haruguru, rufite ibipimo by'ingenzi bisa n'ibirango mpuzamahanga bikomeye (nk'uruhererekane rwa Panasonic GX), bigaragaza imikorere myiza mu igerageza ry'ibintu nyabyo.

Ibisobanuro bigufi: Umuyoboro wa capacitance/ESR uragenda neza mu bushyuhe bwose. Nyuma y'amasaha 2000 yo gusuzuma gusaza, kwangirika kw'ibipimo ni byiza kurusha impuzandengo y'inganda. Amakuru arambuye y'ibizamini aboneka ku rubuga rwemewe.

Ibibazo n'Ibisubizo

Q: Ni gute wagenzura ubushobozi bwo gushyigikira bwa capacitors za MPS ku rwego rwa nanosecond mu mushinga runaka?

A: Birasabwa gukora ibizamini nyabyo ku kibaho cy’ingenzi: Koresha umutwaro w’ikoranabuhanga kugira ngo wigane intambwe y’umuvuduko w’amashanyarazi w’igihe gito (urugero, 100A/100ns), kandi ukurikirane icyarimwe igabanuka ry’umuvuduko w’amashanyarazi ukoresheje probe ifite frequency yo hejuru. Gereranya imiyoboro y’amashanyarazi mbere na nyuma yo gusimbuza capacitor ya MPS; umuvuduko wo hasi n’igihe cyo kugarura vuba bitanga ibimenyetso bitaziguye.

Umwanzuro: Mu gihe cy'ingufu za mudasobwa, guhagarara neza nabyo ni ingenzi.

Bitewe n'irushanwa ry'ingufu z'ikoranabuhanga haba mu bijyanye n'ikoranabuhanga ndetse no kwihaza mu mikorere y'uruhererekane rw'ibikoresho, buri gice cy'uruhererekane rw'amashanyarazi ni ingenzi cyane mu guhangana kw'imikorere y'uruhererekane rw'ibikoresho.Urukurikirane rwa YMIN MPS, hamwe n'amakuru yayo y'ibizamini by'imikorere bigenzurwa ku rwego mpuzamahanga, igisubizo cyihuse gituruka ku ruhererekane rw'ibikoresho byo mu gihugu, hamwe n'inyungu z'ikiguzi, itanga amahitamo yizewe yo gutanga amashanyarazi muri seriveri ya AI, bigafasha mu iterambere rirambye kandi rirambye ry'ibikorwa remezo bya AI mu Bushinwa.

Incamake ku Musozo

Ibintu Bishoboka:Ibikoresho bya VRM bisohora seriveri za AI/seriveri za mudasobwa zifite imikorere yo hejuru CPU/GPU.

Ibyiza by'ingenzi:Igisubizo cy’igihe gito cyo ku rwego rwa Nanosecond (ESR≤3mΩ), gukumira urusaku rwa MHz mu buryo bworoshye, igihe kirekire cyo kumara ubushyuhe bwinshi (105℃/2000h), uburyo bwo guhindura ibintu mu gihugu bufite agaciro kanini.

Icyitegererezo cyatanzwe:YMIN MPS series ultra-low ESR multilayer solid capacitors (capacitors za polymer chip aluminiyumu electrolytic capacitors) (urugero, MPS471MOED19003R).

【Isuzuma n'Itangazamakuru】

1. Isoko ry'amakuru: Isoko ry'amakuru n'imenyekanisha ry'igerageza:

Amakuru y’uruhererekane rwa YMIN MPS aturuka ku rupapuro rwayo rwemewe rw’amakuru.

Amakuru ya Panasonic GX series aboneka ku rupapuro rwayo rw'amakuru ruboneka ku mugaragaro. Ibipimo by'ingenzi by'imikorere (nk'ishusho ya ESR n'umuyoboro w'amazi uhindagurika) byemejwe na laboratwari yacu hakoreshejwe ibikoresho byacu ku bipimo byaguzwe (byaguzwe binyuze mu nzira rusange) mu buryo bumwe bwo gupima.

Igereranya ry'imikorere muri iyi nkuru rishingiye ku masoko yavuzwe haruguru kandi rigamije gutanga isesengura rya tekiniki ridafite aho ribogamiye.

2. Intego y'ikizamini: Ibizamini byose bikorwa mu buryo bumwe kugira ngo injeniyeri zishobore kugereranya imikorere ya tekiniki mu buryo bufatika kandi bushobora kwifashishwa mu buryo buzwi.

3. Inzitizi: Ibisubizo by'ibizamini bigira agaciro gusa ku bipimo byatanzwe mu bihe byihariye by'ibizamini. Amatsinda atandukanye n'uburyo bwo gupima bishobora gutuma amakuru adahuye.

4. Ibirango by'ubucuruzi n'umutungo bwite mu by'ubwenge: Amagambo "Panasonic," "松下," na "GX series" avugwa muri iyi nyandiko ni ibirango by'ubucuruzi cyangwa amazina y'ibicuruzwa by'ababifite kandi akoreshwa gusa mu kugaragaza ibicuruzwa by'ingenzi. Igereranya ry'amakuru muri iyi nyandiko ntirigaragaza ko Panasonic yemera cyangwa ngo yemere ibicuruzwa byacu, kandi ntabwo rigamije kubisuzugura.

5. Igenzura ryigenga: Twishimiye ihererekanya ry’ikoranabuhanga n’igenzura rishingiye ku bipimo n’amabwiriza bingana.
