[Tsiku Lolankhula] YMIN PCIM ivumbulutsa mayankho aluso a capacitor kuti ayendetse bwino ntchito za m'badwo wachitatu wa semiconductor

Chithunzi cha PCIM

Shanghai, September 25, 2025—Pa 11:40 AM lero, pa PCIM Asia 2025 Technology Forum ku Hall N4 ya Shanghai New International Expo Center, Bambo Zhang Qingtao, Wachiwiri kwa Purezidenti wa Shanghai YMIN Electronics Co., Ltd., anakamba nkhani yofunika kwambiri yotchedwa “Innovative Applications of Third-Geration Solutions in New Capacitors Solutions.”

Kulankhulaku kudakhudzanso zovuta zatsopano zobwera ndi matekinoloje amtundu wachitatu wa semiconductor monga silicon carbide (SiC) ndi gallium nitride (GaN) ya ma capacitor pansi pamikhalidwe yovuta kwambiri yogwirira ntchito monga ma frequency apamwamba, magetsi okwera, komanso kutentha kwambiri. Zolankhulazo zidayambitsa kutsogola kwaukadaulo kwa YMIN capacitors ndi zitsanzo zothandiza pakukwaniritsa kachulukidwe wamkulu, ESR yotsika, moyo wautali, komanso kudalirika kwakukulu.

Mfundo Zofunika

Ndi kukhazikitsidwa mwachangu kwa zida za SiC ndi GaN m'magalimoto atsopano opangira mphamvu, kusungirako mphamvu ya photovoltaic, ma seva a AI, magetsi opangira mafakitale, ndi magawo ena, zofunikira zogwirira ntchito zothandizira ma capacitor zikuchulukirachulukira. Capacitors salinso maudindo othandizira; iwo tsopano ndi "injini" yovuta kwambiri yomwe imatsimikizira kukhazikika, kuchita bwino, ndi moyo wautali wa dongosolo. Kupyolera mu luso lazinthu, kukhathamiritsa kwapangidwe, ndi kukonzanso ndondomeko, YMIN yapeza kusintha kwakukulu kwa ma capacitor m'miyeso inayi: voliyumu, mphamvu, kutentha, ndi kudalirika. Izi zakhala zofunikira pakukhazikitsa koyenera kwa mapulogalamu amtundu wachitatu wa semiconductor.

Mavuto Aukadaulo

1. AI Server Power Supply Solution · Kugwirizana ndi Navitas GaN. Zovuta: Kusintha kwa pafupipafupi (> 100kHz), mafunde apamwamba (> 6A), ndi malo otentha kwambiri (> 75 ° C). Yankho:Zithunzi za IDC3otsika-ESR electrolytic capacitors, ESR ≤ 95mΩ, ndi moyo wa maola 12,000 pa 105 ° C. Zotsatira: 60% kuchepetsa kukula kwake, 1% -2% kuwongolera bwino, ndi kuchepetsa kutentha kwa 10 ° C.

2. NVIDIA AI Server GB300-BBU Backup Power Supply · Kuchotsa Musashi waku Japan. Zovuta: Kuthamanga kwamphamvu kwa GPU mwadzidzidzi, kuyankha kwa millisecond, komanso kuwonongeka kwa moyo m'malo otentha kwambiri. Yankho:LIC square supercapacitors, kukana kwamkati <1mΩ, kuzungulira kwa 1 miliyoni, ndi kuyitanitsa mwachangu kwa mphindi 10. Zotsatira: 50% -70% kuchepetsa kukula, 50% -60% kuchepetsa kulemera, ndi kuthandizira kwa 15-21kW pachimake mphamvu.

3. Infineon GaN MOS480W Rail Power Supply Kuchotsa Rubycon Yaku Japan. Zovuta: Kutentha kwakukulu kogwira ntchito kuchokera -40 ° C mpaka 105 ° C, mafunde othamanga kwambiri apano. Yankho: Ultra-otsika kutentha kutentha mlingo <10%, ripple panopa kupirira 7.8A. Zotsatira: Kudutsa -40 ° C otsika kutentha koyambira ndi kutsika kwa kutentha kwapakati-kutsika ndi mayeso opambana a 100%, kukwaniritsa zofunikira za moyo wa zaka 10+ zamakampani a njanji.

4. Galimoto Yatsopano YamagetsiDC-Link Capacitors- Yofanana ndi chowongolera chamoto cha ON Semiconductor cha 300kW. Zovuta: Kusintha pafupipafupi> 20kHz, dV/dt> 50V/ns, kutentha kozungulira> 105°C. Yankho: ESL <3.5nH, moyo> maola 10,000 pa 125 ° C, ndi 30% yowonjezera mphamvu pa voliyumu ya unit. Zotsatira: Kuchita bwino kwakukulu> 98.5%, mphamvu yamagetsi yoposa 45kW/L, ndi moyo wa batri ukuwonjezeka pafupifupi 5%. 5. GigaDevice 3.5kW Kulipira Mulu Njira. YMIN imapereka chithandizo chakuya.

Zovuta: Kusintha kwa PFC pafupipafupi ndi 70kHz, ma frequency a LLC ndi 94kHz-300kHz, kulowera-mbali ripple kupitilira kupitilira 17A, ndipo kukwera kwa kutentha kumakhudza kwambiri moyo.
Yankho: Mapangidwe amitundu yambiri amagwiritsidwa ntchito kuchepetsa ESR/ESL. Kuphatikizidwa ndi zida za GD32G553 MCU ndi GaNSafe/GeneSiC, kachulukidwe kamphamvu ka 137W/in³ kamatheka.
Zotsatira: Kuchita bwino kwambiri kwadongosolo ndi 96.2%, PF ndi 0.999, ndipo THD ndi 2.7%, ikukwaniritsa kudalirika kwakukulu komanso zaka 10-20 za moyo wapamalo opangira magetsi.

Mapeto

Ngati mukufuna kugwiritsa ntchito zida zapamwamba zama semiconductors am'badwo wachitatu ndikufunitsitsa kuphunzira momwe luso la capacitor lingasinthire magwiridwe antchito ndikusintha mtundu wapadziko lonse lapansi, chonde pitani ku YMIN booth, C56 ku Hall N5, kuti mukakambirane mwatsatanetsatane zaukadaulo!
