Mai ka Navitas Semiconductor's Choice of YMIN Capacitors: He Kūkākūkā e pili ana i ka Capacitor Selection for AI Data Center Power Supplies

Hoʻopuka ʻo Navitas Semiconductor i ka CRPS185 4.5kW AI Data Center Power Solution: Optimizing Capacitor Selection

（No ka punaewele o Navitas ka mea kiʻi）

Ua hoʻolauna koke ʻo Navitas Semiconductor i kāna ʻōnaehana mana hou loa-ʻo ka CRPS185 4.5kW AI Data Center Server Power Supply. Hoʻolālā ʻia e hoʻokō i nā koi kiʻekiʻe a me ka hilinaʻi o nā kikowaena data AI, hōʻike ka CRPS185 i kahi holomua nui i ka ʻenehana mana. ʻAʻole wale kēia hoʻonā e hoʻokō i ka mana mana alakaʻi alakaʻi o 137W/in³ a ʻoi aku ka maikaʻi ma mua o 97%, akā ua hoʻokomo pū ʻia ka ʻenehana capacitor holomua e hoʻomaikaʻi i ka hana holoʻokoʻa.

I loko o ka mana mana CRPS185, koho ʻia nā capacitors electrolytic alumini CW3 o YMIN, me ka volta helu o 450V a me ka capacitance o 1200µF. Kaulana kēia mau capacitors no kā lākou hana kiʻekiʻe-frequency maikaʻi loa a me ke kūpaʻa, e kūpono loa iā lākou no ka mana kiʻekiʻe a me nā hoʻolālā mana kiʻekiʻe. ʻO ka haʻahaʻa ESR (Equivalent Series Resistance) o ka moʻo CW3 e kōkua i ka hōʻemi ʻana i ka nalowale o ka ikehu, ʻoiai ʻo kona capacitance a me ka lōʻihi e hāʻawi i ke kākoʻo hilinaʻi ma lalo o nā kūlana haʻahaʻa kiʻekiʻe.

He mea koʻikoʻi ke koho ʻana i nā capacitors lako mana no ka hoʻokō ʻana i ka ʻōnaehana mana. Loaʻa nā ʻano capacitors like ʻole i nā pono a me nā hemahema, e pili ana i ka pono o ka lako mana, kūpaʻa, a me ke kumukūʻai. Eia nā hiʻohiʻona nui a me nā noi o ka Laminated Solid State Aluminum Electrolytic, electrolytic, a me tantalum capacitors:

ʻO nā pono a me nā pōʻino o nā ʻano Capacitor like ʻole

• Laminated Solid State Aluminum Electrolytic Capacitors:
  • Pono:Loaʻa ka ESR haʻahaʻa a me ka pane alapine kiʻekiʻe o ka Laminated Solid State Aluminum Electrolytic Capacitors, e kūpono iā lākou no ka mana kiʻekiʻe a me nā noi kiʻekiʻe. Hāʻawi lākou i ka hilinaʻi kiʻekiʻe a me ke kūpaʻa ʻoiai i nā wahi hana paʻakikī.
  • Nā hemahema:ʻOiai e hana maikaʻi ana kēia mau capacitors i nā noi kiʻekiʻe, he kumu kūʻai lākou a loaʻa paha nā palena i ke koho capacitance.
• Nā Kaila Electrolytic:
  • Pono:Hāʻawi nā capacitors electrolytic i nā waiwai capacitance kiʻekiʻe, e hoʻolilo iā lākou i mea kūpono no nā noi kānana nui. ʻO kā lākou kumukūʻai kūpono e hoʻolilo iā lākou i koho maʻamau no nā mea mana.
  • Nā hemahema:Loaʻa i nā capacitors electrolytic ka ESR kiʻekiʻe, hiki ke alakaʻi i ka nalowale o ka ikehu. He pōkole ko lākou ola a ʻoi aku ka maʻalahi i nā ʻano like ʻole o ka wela a me ka volta.
• ʻO Tantalum Capacitors:
  • Pono:ʻO nā capacitor Tantalum he paʻa a loaʻa ka capacitance kiʻekiʻe, e hoʻolilo iā lākou i mea kūpono no nā noi ākea. Loaʻa iā lākou ka ESR haʻahaʻa, kahi e hoʻomaikaʻi ai i ka pono o ka mana a me ke kūpaʻa ʻoiai e mālama ana i ka capacitance paʻa.
  • Nā hemahema:ʻOi aku ke kumukūʻai o nā capacitor Tantalum a hiki ke hāʻule ma lalo o nā kūlana over-voltage, e koi ana i ke koho akahele a me ka hoʻohana ʻana.

Hoʻohana ka ʻenehana mana CRPS185 i nā capacitors series CW3 o YMIN e hoʻokō i ka hana kiʻekiʻe-frequency a me ka capacitance ʻoiai e hōʻoia ana i ka pono holoʻokoʻa a me ka paʻa. Hōʻike kēia i nā koi ʻenehana koʻikoʻi no ka hoʻolālā mana hana kiʻekiʻe a hāʻawi i ke kākoʻo hilinaʻi no nā kaiapuni kiʻekiʻe e like me nā kikowaena data AI.

Ka hopenaʻO Navitas Semiconductor's CRPS185 4.5kW AI Data Center Power Supply Solution, ma o ke koho capacitor kiʻekiʻe a me ka hoʻonui ʻana, hōʻike i nā mea hou loa i ka ʻenehana mana kūpono. ʻO ka hoʻomaopopo ʻana i nā pono a me nā hemahema o nā ʻano capacitor like ʻole e kōkua i nā mea hoʻolālā e hana i nā koho maikaʻi loa no nā ʻōnaehana mana kiʻekiʻe. ʻO ka hoʻohana kūleʻa ʻana o ka hopena CRPS185 ʻaʻole ia e hōʻike wale i ka ʻenehana mana ʻokiʻoki akā hāʻawi pū kekahi i ke kākoʻo paʻa no nā kaiapuni helu koʻikoʻi o nā kikowaena data AI.
