Isishwankathelo: Ukwanda ngokukhawuleza kwamandla ekhompyutha kwiitships ze-AI kutyhala iinethiwekhi zazo zombane ukuya kwimida yazo. I-core voltage yehla ukuya kwi-0.8-1.2V, kwaye ukunyuka kwamandla ombane wesigaba esinye kufikelela kumakhulu ee-amps, okubangela izithuba zamandla ombane ezidlulayo zenqanaba le-nanosecond (10-100ns) kunye nokuphazamiseka kwengxolo yokutshintsha kwenqanaba le-MHz kwisiphumo se-VRM. Ii-capacitors zemveli, ngenxa ye-ESR yazo ephezulu kunye ne-impedance ephezulu ye-frequency, ziye zaba yingxaki yokuzinza kwenkqubo, ngelixa izisombululo zamazwe ngamazwe eziphezulu zibeka umngcipheko wekhonkco lokunikezela. Eli nqaku lihlalutya izalathisi ezintathu eziphambili zesiphelo sonikezelo lwamandla kwaye lisebenzisa idatha yokulinganisa elinganisiweyo evela kwi-YMIN MPS series ultra-low ESR multilayer solid capacitors (conductive polymer chip aluminium electrolytic capacitors) njengomzekelo wokubonelela iinjineli ngendlela yokutshintsha enokuthembeka okuphezulu ehlangabezana nemigangatho yokusebenza yamazwe ngamazwe kwaye inekhonkco lokubonelela elaneleyo nelilawulekayo.
Intshayelelo: "Umgcini Ongabonakaliyo" weSiphelo soMbane uyachazwa ngokutsha
Kwiseva ze-AI ezilandela amandla okugqibela ekhompyutha, i-power intelligence (PI) yeyona nto ibalulekileyo yozinzo. Ukunyuka komthwalo we-nanosecond level ye-CPUs/GPUs kufana "neziphepho zangoku." Ukuba i-VRM output capacitor ayinakukwazi ukuphinda izalise amandla ngokukhawuleza ngexesha le-nanosecond-level idling window ngaphambi kokuba i-control loop iphendule (ii-microseconds), iya kubangela ngokuthe ngqo ukuhla kwe-core voltage, okukhokelela kwiimpazamo zokubala okanye ukunciphisa i-frequency. Kwangaxeshanye, ukuba ingxolo yokutshintsha i-MHz ayifunxwa, iya kuphazamisana nemiqondiso yesantya esiphezulu. Ke ngoko, i-output capacitor iphuculwe ukusuka "kwi-basic filtering" ukuya kwi-final energy storage buffer kunye ne-noise discharge channel "yokukhusela ngokuchanekileyo."
Iimpawu Ezintathu Eziphambili: Kutheni Izisombululo Zemveli Zingaphumeleli?
Inkxaso yeThutyana yeNqanaba leNanosecond: I-ESR yeyona nto ibalulekileyo. Isantya sempendulo sixhomekeke kukumelana kwangaphakathi; i-ESR ephantsi kakhulu ye-≤3mΩ ngumda oqinileyo wokuhlangabezana nokukhululwa ngokukhawuleza kwetshaja yenqanaba le-nanosecond.
Ukuncitshiswa kweNgxolo kwiNqanaba leMHz: Iimpawu zokuThintela uFrequency eziPhakamileyo zibalulekile. I-capacitor kufuneka igcine i-impedance ephantsi kakhulu kwi-switching frequency kunye ne-harmonics yayo ukuze ibonelele ngendlela efanelekileyo yokuya emhlabeni ukuze kubekho ingxolo, ukuqinisekisa ukuthembeka kwemiqondiso ye-PCIe/DDR.

| I-Ripple Current elinganisiweyo (45℃/100kHz) | 10.2 A_₍rms₎ | 10.2 A_₍rms₎ | Ihlangabezana nokusebenza komthwalo ophezulu ixesha elide kunye nokunyuka kobushushu okuphantsi |
| Ixesha lobomi (105℃) | iiyure ezingama-2000 | iiyure ezingama-2000 | Qinisekisa ukuthembeka kwexesha elide kwaye unciphise i-TCO |
| Uluhlu lobushushu bokusebenza | -55℃ ~ +105℃ | -55℃ ~ +105℃ | Ziqhelanise neendawo ezinobungozi zeziko ledatha |
Inkcazo emfutshane: I-capacitance/ESR curve igudile kulo lonke uhla lobushushu. Emva kweeyure ezingama-2000 zovavanyo lokwaluphala, ukuwohloka kweparameter kungcono kunomndilili weshishini. Idatha yovavanyo eneenkcukacha ingafumaneka kwiwebhusayithi esemthethweni.
