Ngenxa yokukhula okukhulu kweemfuno zamandla ekhompyutha ye-AI, iimfuno zombane ozinzileyo kwi-DC-DC converter yeebhodi zee-motherboard zeseva ziya ziba nzima ngakumbi.
Ukukhula okukhulu kwiimfuno zokucubungula idatha ye-AI kubeka iimfuno eziphezulu kwimodyuli yokulawula amandla kwiibhodi zee-motherboard zeseva. Njengenxalenye yokuguqula amandla angundoqo, i-DC-DC converter kufuneka iguqule ngokuchanekileyo amandla e-DC aphezulu e-12V abe ngamandla aphantsi e-voltage (njenge-1V, i-1.2V) afunekayo ngamacandelo anjenge-CPU kunye ne-GPU. Uzinzo lwayo lumisela ngokuthe ngqo ukuthembeka kwamandla ekhompyutha ye-AI.
Uthotho lwe-NPC lwe-Yongming Electronics lwee-capacitors ze-electrolytic ze-polymer solid aluminium ezinee-layer ezininzi, ezinexabiso lazo eliphantsi kakhulu le-ESR, zihambelana ngokugqibeleleyo neemfuno ezingqongqo zee-converters ze-motherboard ze-server DC-DC.
01 I-ESR Ephantsi Kakhulu: Ilitye Lembombo Lozinzo Lweseva Ye-AI
Umsinga womatshini omnye oveliswa yiseva ngexesha lokusebenza unokufikelela ngaphezulu kwe-130A. Ngeli xesha, ii-capacitors kufuneka zidlale indima ebalulekileyo ekugcineni nasekuhluzeni amandla.
Ii-capacitors ze-ymin, ezinokumelana kwazo okulinganayo okuphantsi kakhulu (ESR), zinokuphendula ngokukhawuleza kutshintsho olukhawulezileyo kwimfuno yangoku evela kwiitships ze-AI, ziqinisekisa ukuphuma kombane okuzinzileyo nokuba phantsi kwemithwalo eguquguqukayo.
I-ESR ephantsi ayinciphisi nje kuphela ukulahleka kwamandla kwaye iphucula ukusebenza kakuhle kokuguqulwa kwamandla kodwa ikwanciphisa ukuveliswa kobushushu, iqinisekisa ukusebenza kweseva okuqhubekayo nokusebenza kakuhle phantsi kwemithwalo ephezulu kunye neendawo ezintsonkothileyo zesicelo.
02 Ukunyamezelana Kwangoku KweRipple: Isitshixo Sokuphatha Imithwalo Engxamisekileyo
Xa umthwalo wekhompyutha weeseva ze-AI utshintshatshintsha phakathi kweencochoyi kunye nee-tawrs, inkqubo yokubonelela ngombane ifuna amandla ombane aqinileyo ngoko nangoko.
Ii-capacitor ze-YMIN zinokunyamezelana okuhle kakhulu komsinga we-ripple; i-capacitor enye inokumelana nemisinga ye-inrush enkulu kakhulu edlula i-20A, inceda umbane weseva ukuba uphathe imiba yokuxinana ngokuzolileyo kwaye uphephe ukungazinzi kwenkqubo okubangelwa lutshintsho lomsinga ngesiquphe.
Ukunyamezelana kombane we-ripple kuqinisekisa ukuba ii-capacitors zisebenza ngokuzinzileyo nangokuthembekileyo kwiindawo ezinzima, zixhathisa ngempumelelo umonakalo woxinzelelo obangelwa lutshintsho lwangoku olukhawulezileyo kwaye zandise ubomi beseva.
Izisombululo ezincinci ze-03 zeendawo ezishushu kakhulu
Ukuze kuhlangatyezwane neemfuno ezikhulayo zoxinano lwamandla kwiiseva ze-AI, ii-capacitors ze-YMIN zisebenzisa uyilo oluncinci, olubonelela ngomthamo omkhulu wokugcina amandla ngaphakathi kwendawo encinci.
Uyilo oluncinci luhambelana nomkhwa weeseva ezincinci, nto leyo egcina indawo exabisekileyo kwi-chassis yeeseva ezinoxinano olukhulu.
Ii-capacitors ze-ymin zigcina ubomi obude kakhulu obungaphezulu kweeyure ezingama-3000 nokuba zikwi-105℃, zifikelela ubomi obuqhelekileyo beeyure ezingama-2000 kwi-125℃, kwaye zivumela ukusebenza okungaphazanyiswayo iiyure ezingama-24/7.
Olu phawu luvumela ii-capacitors ukuba zikwazi ukumelana nobushushu obuphezulu beendawo zedatha, ziqinisekisa ukusebenza kwenkqubo okuzinzileyo ixesha elide.
Ukwenziwa lula kwe-capacitor, i-capacitance density ephezulu, i-ESR ephantsi, kunye nobomi obude be-YMIN capacitors kuzenza zibe lukhetho olufanelekileyo kwii-converter ze-DC-DC kwiibhodi zee-motherboard ze-AI server. Ngokusetyenziswa ngokubanzi kwezixhobo ze-semiconductor zesizukulwana sesithathu, izixhobo zamandla zeseva zifuna ii-capacitor ezisebenzayo kakhulu.
Ii-capacitor ze-YMIN zisetyenziswe ngempumelelo kwizixhobo eziphambili ze-server ze-4.5kW kunye ne-8.5kW zehlabathi, zifezekisa ukusebenza okungaphezulu kwe-97%, zibonelela ngenkxaso ethembekileyo kwiimfuno zamandla ezikhulayo zamaziko edatha e-AI.
