Kuchokera ku Navitas Semiconductor's Choice of YMIN Capacitors: Zokambirana pa Capacitor Selection for AI Data Center Power Supplies

Navitas Semiconductor Ikuyambitsa CRPS185 4.5kW AI Data Center Power Solution: Kupititsa patsogolo Kusankhidwa kwa Capacitor

(Zithunzi zimachokera patsamba lovomerezeka la Navitas)

Navitas Semiconductor posachedwapa yatulutsa njira yake yaposachedwa yamagetsi-CRPS185 4.5kW AI Data Center Server Power Supply. CRPS185 idapangidwa kuti ikwaniritse magwiridwe antchito komanso kudalirika kwa malo opangira ma data a AI, CRPS185 ikuyimira kupita patsogolo kwaukadaulo wamagetsi. Njira yothetsera vutoli sikuti imangokwaniritsa mphamvu zotsogola zamakampani za 137W/in³ komanso kuchita bwino kwambiri kuposa 97%, komanso kumaphatikiza ukadaulo wapamwamba wa capacitor kuti upititse patsogolo magwiridwe antchito.

Mu njira yamagetsi ya CRPS185, YMIN's CW3 mndandanda wa aluminiyamu electrolytic capacitors amasankhidwa, okhala ndi voliyumu ya 450V ndi mphamvu ya 1200µF. Ma capacitor awa ndi odziwika chifukwa cha magwiridwe antchito apamwamba kwambiri komanso kukhazikika, zomwe zimawapangitsa kukhala oyenera kuchulukira kwambiri kwamagetsi komanso mapangidwe apamwamba amagetsi. ESR yotsika (Equivalent Series Resistance) ya mndandanda wa CW3 imathandizira kuchepetsa kutayika kwa mphamvu, pamene mphamvu zake ndi kulimba kwake zimapereka chithandizo chodalirika pansi pa katundu wapamwamba.

Kusankha ma capacitor oyenera amagetsi ndikofunikira kuti muwongolere magwiridwe antchito amagetsi. Mitundu yosiyanasiyana ya ma capacitor ili ndi zabwino ndi zovuta zosiyanasiyana, zomwe zimakhudza mphamvu yamagetsi, kukhazikika, komanso mtengo wake. Nazi zizindikiro zazikulu ndi ntchito za Laminated Solid State Aluminium Electrolytic, electrolytic, ndi tantalum capacitors:

Ubwino ndi Kuipa kwa Mitundu Yosiyanasiyana ya Capacitor

• Laminated Solid State Aluminium Electrolytic Capacitors:
  • Ubwino:Laminated Solid State Aluminium Electrolytic Capacitors ali ndi ESR yotsika komanso kuyankha kwafupipafupi, kuwapangitsa kukhala oyenera kugwiritsa ntchito mphamvu zambiri komanso kugwiritsa ntchito pafupipafupi. Amapereka kudalirika kwakukulu komanso kukhazikika ngakhale m'malo ovuta kugwira ntchito.
  • Zoyipa:Ngakhale ma capacitor awa amachita bwino kwambiri pamapulogalamu apamwamba kwambiri, amakhala okwera mtengo ndipo amatha kukhala ndi malire pakusankha kwamphamvu.
• Electrolytic Capacitors:
  • Ubwino:Electrolytic capacitor imapereka mphamvu zambiri, zomwe zimawapangitsa kukhala abwino pazosefera zazikuluzikulu. Kutsika mtengo kwawo kumawapangitsa kukhala kusankha kofala kwa zigawo zamphamvu.
  • Zoyipa:Electrolytic capacitors ali ndi ESR yapamwamba, yomwe ingayambitse kutaya mphamvu kwambiri. Moyo wawo ndi waufupi ndipo amatha kutengera kutentha ndi kusinthasintha kwamagetsi.
• Tantalum Capacitors:
  • Ubwino:Tantalum capacitor ndi yaying'ono ndipo ali ndi mphamvu zambiri, zomwe zimawapangitsa kukhala abwino kwa ntchito zopanda malo. Amakhalanso ndi ESR yotsika, yomwe imapangitsa kuti mphamvu ikhale yogwira ntchito komanso yokhazikika pamene imakhala ndi mphamvu yokhazikika.
  • Zoyipa:Ma capacitor a Tantalum ndi okwera mtengo ndipo amatha kulephera pamagetsi ochulukirapo, zomwe zimafunikira kusankhidwa mosamala ndikugwiritsa ntchito.

Yankho lamphamvu la CRPS185 limagwiritsa ntchito ma capacitor a YMIN a CW3 kuti akwaniritse magwiridwe antchito apamwamba kwambiri ndikuwonetsetsa kuti magwiridwe antchito ndi bata. Izi zikuwonetseratu zofunikira zaumisiri pakupanga mphamvu zogwira ntchito kwambiri ndipo zimapereka chithandizo chodalirika cha malo odzaza kwambiri monga malo a data a AI.

MapetoNavitas Semiconductor's CRPS185 4.5kW AI Data Center Power Supply Solution, kudzera pakusankha kwapamwamba kwa capacitor ndi kukhathamiritsa, ikuwonetsa zopambana zaposachedwa kwambiri muukadaulo wamagetsi waluso. Kumvetsetsa ubwino ndi kuipa kwa mitundu yosiyanasiyana ya capacitor kumathandiza okonza kupanga zisankho zabwino kwambiri zogwiritsira ntchito mphamvu zamagetsi. Kugwiritsa ntchito bwino kwa yankho la CRPS185 sikungoyimira ukadaulo wamagetsi otsogola komanso kumapereka chithandizo champhamvu pamagawo ofunikira a ma data a AI.
