Amaqhawe Afihliwe Ngemuva Kwamandla Ekhompyutha E-AI: Indlela Ama-Capacitor Aphezulu Akhiqizwa Ngayo Ekhaya (Φ30×70mm 450V/1400µF, 105℃/3000H) Xazulula Izinselele Ezintathu Ezinkulu Ezitholakala Kuma-Power Supplies E-Server

Ngokukhula okukhulu kwamandla ekhompyutha ye-AI, izikhungo zedatha zibhekene nengcindezi yokuthuthukisa engakaze ibonwe. Njengoba "inhliziyo yamandla" yamaseva e-AI, umklamo wokunikezwa kwamandla we-AC-DC ubhekene nezinselele ezingakaze zibonwe ngaphambili: ungafinyelela kanjani ukuminyana kwamandla okuphezulu, isikhathi eside sokuphila, kanye nokuthembeka okuqinile ngaphakathi kwesikhala esilinganiselwe? Lokhu akuyona nje inkinga yobuchwepheshe, kodwa futhi kubalulekile ekuqinisekiseni ukukhishwa okuqhubekayo nokuzinzile kwamandla ekhompyutha ye-AI.

I-YMIN Electronics, umhlinzeki ohamba phambili wezixazululo ze-capacitor zasekhaya onolwazi oluningi emkhakheni we-capacitor enamandla aphezulu, wethule uchungechunge lwe-IDC3 lwama-capacitor e-aluminium electrolytic asebenza ngamandla aphezulu ukuze abhekane nezidingo ezithile zamandla e-AI server, enikeza ikhambi lobuchwepheshe elisha lokuxazulula izinkinga embonini.

Izimo Zokusebenza

• Indawo: Isitoreji samandla/i-capacitor yesihlungi ngemuva kwe-AC-DC front-end PFC (Ukulungiswa Kwezici Zamandla) I-DC-Link (ibhasi le-DC) (isisombululo esijwayelekile)

• Amandla: 4.5kW–12kW+; Isici sefomu: Ukunikezwa kwamandla kweseva okufakwe ku-rack/ukunikezwa kwamandla amakhulu esikhungo sedatha

• Imvamisa: Njengoba ukusetshenziswa kwe-GaN (Gallium Nitride)/SiC (Silicon Carbide) kukhula, imvamisa yokushintsha ivame ukuba sebangeni elisukela kumashumi e-kHz kuya kumakhulu e-kHz (kuye ngokuthi iphrojekthi iyasebenza; lesi sihloko sicaphuna imininingwane efana ne-120kHz)

• Ukusebenza Nokushisa: Izikhungo zedatha zivame ukusebenza amahora angama-24 ngosuku, izinsuku eziyi-7 ngesonto; ugesi unokushisa okuphezulu kwangaphakathi, okudinga ukunakwa kokushisa kwe-capacitor/ukwehla kwempilo yonke (izimo zokusebenza ezivamile zokushisa okuphezulu)

Izinselele Ezintathu Ezinkulu: Ukwembula Inkinga Ye-High-Voltage Capacitor ku-AI Server Power Supply Design

Ekuklanyweni kwezingxenye ze-AC-DC zezinsiza zamandla zeseva ye-AI kanye nezinsiza zamandla eziyinhloko zesikhungo sedatha, onjiniyela ngokuvamile babhekene nezinselele ezintathu ezinkulu:

① Ukuphikisana phakathi kwesikhala nomthamo: Esikhaleni esivalekile seseva yokufaka i-rack engu-1U, ama-capacitor e-horn ajwayelekile ajwayelekile avame ukubhekana nenkinga yobukhulu obulinganiselwe. Ukufinyelela umthamo wokugcina amandla owanele ngaphakathi kokuphakama okulinganiselwe kuyinselele ebalulekile okumele inqotshwe lapho kuklanywa izinsiza zamandla ezinamandla aphezulu.

② Izinselele Zokuphila Ezindaweni Ezinokushisa Okuphezulu: Izindawo zegumbi leseva ye-AI ngokuvamile ziyizindawo ezinokushisa okuphezulu, okubeka ingcindezi enkulu ekuphathweni kokushisa kokunikezwa kwamandla. Ukusebenza kwe-capacitor engu-450V/1400μF ngaphansi kwenselele yokuphila kokushisa okuphezulu engu-105℃ kuthinta ngqo ukuthembeka kwesikhathi eside kohlelo.

③ Izidingo Zokusebenza Ngaphansi Komkhuba Wemvamisa Ephakeme: Njengoba kusetshenziswa kabanzi amadivayisi amasha kagesi njenge-GaN/SiC, imvamisa yokushintsha ukunikezwa kwamandla iyanda njalo, okubeka izidingo eziphezulu ku-ESR kanye nekhono lamanje le-ripple lama-capacitor ukugwema ingozi yokungasebenzi kwesikhathi sohlelo.

I-YMIN IDC3

Ukuchaza Kabusha Imingcele Yokusebenza Yama-Capacitors Aphezulu Ngobuchwepheshe

Ukuze kuxazululwe izinselele okukhulunywe ngazo ngenhla, uchungechunge lwe-YMIN IDC3 lufinyelele impumelelo ephelele ngezindlela ezintathu: izinto zokwakha, isakhiwo, kanye nenqubo:

1. Ukuguquka Kobuningi: Ukwanda Komthamo okungu-70% ngaphakathi kwe-Φ30×70mm

Kusetshenziswa iphakheji encane ye-capacitor enomumo wophondo ongu-Φ30×70mm, umthamo ophezulu ongu-450V/1400μF ufinyelelwa ngaphakathi kwemingcele evamile yokuphakama kokunikezwa kwamandla kweseva ye-1U ejwayelekile. Uma kuqhathaniswa nemikhiqizo yendabuko enobukhulu obufanayo, umthamo ukhushulwa ngaphezu kuka-70% (uma kuqhathaniswa nobubanzi bomthamo obujwayelekile bama-capacitor anomumo wophondo ongu-450V asetshenziswa njalo embonini), okuxazulula ngempumelelo ukuphikisana phakathi kobuningi bomthamo ophezulu nendawo.

2. Ukuphumelela Kwesikhathi Sokuphila: Ukuqina Kuhlolwe ku-105℃

Ngokusebenzisa ukwakheka kwe-electrolyte okulungiselelwe kanye nesakhiwo se-anode foil, uchungechunge lwe-IDC3 lubonisa ukusebenza kahle kakhulu kokuphila komthwalo ngaphansi kwezimo ezinzima ezingu-105℃. Lo mklamo uvumela ama-capacitor ukuthi alondoloze ukuzinza kwesikhathi eside endaweni yokushisa ephezulu yezikhungo zedatha, okubhekana kalula nenselele yemboni yokuphila isikhathi esifushane ngenxa yokushisa okuphezulu.

3. Ukuzivumelanisa Nezimo Eziphezulu: Kwenzelwe i-GaN/SiC Era

Isebenzisa umklamo we-ESR ophansi, ingamelana nogesi ophezulu we-ripple ku-120kHz. Lesi sici sivumela uchungechunge lwe-IDC3 ukuthi luzivumelanise kangcono ne-topology yokushintsha imvamisa ephezulu ngokusekelwe ku-GaN (Gallium Nitride)/SiC (Silicon Carbide) (ngaphansi kwemininingwane yeshidi ledatha), okunikeza ukwesekwa okuqinile kokuthuthukisa ukusebenza kahle kwamandla aphezulu. Ngokungafani nokukhethwa kwe-capacitor yebhasi yendabuko egxile kakhulu ku-ripple evamise ukuba phansi, amandla aphezulu okusebenza kwamapulatifomu e-GaN/SiC adinga ukuqinisekiswa ngasikhathi sinye kwe-ESR kanye namakhono wamanje we-ripple evamise ukuba sezingeni eliphezulu ngaphansi kwemininingwane yeshidi ledatha.

Qaphela: Amapharamitha abalulekile kulesi sihloko avela ku-Uchungechunge lwe-YMIN IDC3ishidi ledatha/umbiko wokuhlola; ngaphandle uma kuchazwe ngenye indlela, i-ESR/i-ripple current ichazwa ngokwezincazelo zeshidi ledatha (isb., 120kHz), futhi inguqulo yakamuva yeshidi ledatha izosebenza.

Ukuqamba Okusha Ngokubambisana: Ukuthembeka Nokuqinisekiswa Kokusebenza Kusukela ku-4.5kW Kuya ku-12kW

I-YMIN igcina ukubambisana okujulile kwezobuchwepheshe nabakhiqizi be-semiconductor yamandla e-GaN abaphambili embonini njenge-Navitas (ngokusho kolwazi lomphakathi). Kumaphrojekthi okuphakelwa kwamandla eseva ye-AI asukela ku-4.5kW kuya ku-12kW kanye namazinga aphezulu amandla, ama-capacitor e-electrolytic e-aluminium acwebezelayo ochungechunge lwe-IDC3 abonise ukusebenza okuhle kakhulu.

Le modeli yokuthuthukisa ngokubambisana ayigcini nje ngokuqinisekisa ukuthembeka komkhiqizo kodwa futhi ihlinzeka ngesisekelo esiqinile sobuchwepheshe sokuthuthuka okuqhubekayo kwezinsiza zamandla zeseva ye-AI. Uchungechunge lwe-IDC3 lwe-YMIN selube yisisombululo esithandwayo samaphrojekthi amaningana eseva ye-AI ephezulu (ngokusho kolwazi lomphakathi), ngokusebenza okufana nemikhiqizo ehamba phambili yamazwe ngamazwe.

Okungaphezu Kwemikhiqizo Nje: Indlela i-YMIN Ehlinzeka Ngayo Izixazululo Zezinga Lesistimu Zamaseva E-AI

Esikhathini sokukhula okukhulu kwamandla ekhompyutha ye-AI, ukuthembeka kwezinhlelo zokuphakelwa kwamandla kubaluleke kakhulu. I-YMIN Electronics iyaqonda ngokujulile izidingo eziqinile zomklamo wokuphakelwa kwamandla eseva ye-AI futhi inikeza imboni ikhambi eliphelele elilinganisela ubuningi bamandla aphezulu, isikhathi eside sokuphila, kanye nokuthembeka okuphezulu ochungechungeni lwe-IDC3.

Okulandelayo kuyireferensi yokukhetha evamile yama-capacitor e-aluminium electrolytic asebenza ngogesi aphezulu e-IDC3 ochungechungeni lwe-IDC3 kumishini yamandla yeseva ye-AI, okukusiza ukuthi uhambisane ngokushesha nezidingo zesistimu:

Ukusungula Izinto Ezintsha Akupheli: I-YMIN Iyaqhubeka Nokunikeza Amandla Azinzile Engqalasizinda Ye-AI

Esikhathini samandla okusebenzisa ikhompyutha, ukunikezwa kwamandla okuzinzile kubalulekile. I-YMIN Electronics, enama-capacitor ayo e-aluminium electrolytic asebenza ngogesi aphezulu e-IDC3 njengomgogodla, ihlinzeka njalo ngokusekelwa kwe-capacitor okuthembekile kwengqalasizinda yekhompyutha ye-AI. Asigcini nje ngokuhlinzeka ngemikhiqizo, kodwa futhi nezixazululo zezinga lesistimu ezisekelwe ekuqondeni okujulile kobuchwepheshe.

Uma uklama izinsiza zamandla zeseva ye-AI yesizukulwane esilandelayo, i-YMIN ikulungele ukukusiza ukuthi udlule imingcele yokuklama ngobuchwepheshe obusha futhi uhambisane ndawonye negagasi lamandla okusebenzisa ikhompyutha.
