Kusuka ku-Navitas Semiconductor's Choice of YMIN Capacitors: Ingxoxo ngokukhetha i-Capacitor ye-AI Data Center Power Supplies

I-Navitas Semiconductor Yethula i-CRPS185 4.5kW AI Data Center Power Solution: Ukuthuthukisa Ukukhetha Kwe-Capacitor

(Izinto zesithombe zivela kuwebhusayithi esemthethweni ye-Navitas)

I-Navitas Semiconductor isanda kwethula isisombululo sayo sakamuva samandla—i-CRPS185 4.5kW AI Data Center Server Power Supply. Idizayinelwe ukuhlangabezana nezimfuneko zokusebenza okuphezulu nokuthembeka kwezikhungo zedatha ye-AI, i-CRPS185 imele intuthuko enkulu kubuchwepheshe bamandla. Lesi sixazululo asifinyeleli kuphela ukuminyana kwamandla ahamba phambili embonini angu-137W/in³ nokusebenza kahle okudlula u-97%, kodwa futhi sihlanganisa ubuchwepheshe be-capacitor obuthuthukisiwe ukuze kuthuthukiswe ukusebenza kukonke.

Kusixazululo samandla se-CRPS185, kukhethwa ama-aluminium electrolytic capacitor ochungechunge lwe-YMIN's CW3, ane-voltage elinganiselwe engu-450V namandla angu-1200µF. Lawa ma-capacitor adume ngokusebenza kwawo okuhle kakhulu kwe-high-frequency kanye nokuzinza, okuwenza afanelekele kakhulu ukuminyana kwamandla aphezulu kanye nemiklamo yamandla esebenza kahle kakhulu. I-ESR ephansi (Equivalent Series Resistance) yochungechunge lwe-CW3 isiza ukunciphisa ukulahlekelwa kwamandla, kuyilapho amandla ayo nokuqina kunikeza ukusekelwa okuthembekile ngaphansi kwezimo zomthwalo ophezulu.

Ukukhetha ama-capacitor anikezela amandla alungile kubalulekile ekuthuthukiseni ukusebenza kwesistimu yamandla. Izinhlobo ezahlukene zama-capacitor zinezinzuzo nezinkinga ezihlukahlukene, ezithinta ukusebenza kahle kwamandla kagesi, ukuzinza, kanye nezindleko. Nazi izici eziyinhloko kanye nokusetshenziswa kwe-Laminated Solid State Aluminium Electrolytic, electrolytic, kanye ne-tantalum capacitor:

Izinzuzo kanye Nemibi Yezinhlobo Ezihlukene Ze-Capacitor

• I-Laminated Solid State Aluminium Electrolytic Capacitors:
  • Izinzuzo:Ama-Laminated Solid State Aluminium Electrolytic Capacitors ane-ESR ephansi kanye nokusabela kwefrikhwensi ephezulu, okuwenza afanelekele ukuminyana kwamandla aphezulu kanye nezicelo zamafrikhwensi aphezulu. Banikeza ukwethembeka okuphezulu nokuzinza ngisho nasezindaweni zokusebenza ezinzima.
  • Ububi:Nakuba lawa ma-capacitor enza kahle kakhulu ezinhlelweni ze-high-frequency, ayabiza futhi angase abe nemikhawulo ekukhetheni amandla.
• Ama-Electrolytic Capacitors:
  • Izinzuzo:Ama-Electrolytic capacitor anikezela ngamavelu amandla aphezulu, awenza afaneleke ezinhlelweni zokuhlunga zamandla amakhulu. Ukusebenza kahle kwabo kwezindleko kubenza babe ukukhetha okuvamile kwezingxenye zamandla.
  • Ububi:Ama-electrolytic capacitor ane-ESR ephakeme, engaholela ekulahlekelweni kwamandla okukhulu. Ukuphila kwabo kufushane futhi kulula kakhulu ukungenwa amazinga okushisa nokwehluka kwamandla kagesi.
• I-Tantalum Capacitors:
  • Izinzuzo:Ama-Tantalum capacitor ahlangene futhi anamandla aphezulu, okuwenza alungele izinhlelo zokusebenza ezinesikhala. Futhi bane-ESR ephansi, ethuthukisa ukusebenza kahle kwamandla nokuzinza ngenkathi igcina amandla azinzile.
  • Ububi:Ama-Tantalum capacitor ayabiza futhi angahluleka ngaphansi kwezimo ze-voltage eningi, edinga ukukhethwa nokusetshenziswa ngokucophelela.

Isixazululo samandla se-CRPS185 sisebenzisa ama-capacitor ochungechunge lwe-YMIN's CW3 ukuze kuthuthukiswe ukusebenza kwemvamisa ephezulu nekhono ngenkathi kuqinisekiswa ukusebenza kahle okuphelele nokuzinza. Lokhu kugqamisa izimfuneko zobuchwepheshe ezibalulekile zokuklama amandla asebenza kahle futhi kunikeza ukwesekwa okuthembekile kwezindawo ezinomthwalo omkhulu njengezikhungo zedatha ye-AI.

IsiphethoI-Navitas Semiconductor's CRPS185 4.5kW AI Data Center Power Supply Solution, ngokukhetha okuthuthukisiwe kwe-capacitor nokwenza kahle, ibonisa impumelelo yakamuva kubuchwepheshe bamandla obusebenzayo. Ukuqonda okuhle nokubi kwezinhlobo ezahlukene ze-capacitor kusiza abaklami benze izinqumo ezingcono kakhulu zamasistimu amandla asebenza kahle kakhulu. Ukusetshenziswa okuyimpumelelo kwesixazululo se-CRPS185 akumeli nje kuphela ubuchwepheshe bamandla obunqamulelayo kodwa futhi kunikeza ukusekelwa okuqinile kwezindawo ezidingwayo zokubala zezikhungo zedatha ye-AI.
