[Tsiku Lolankhula] YMIN PCIM yavumbulutsa njira zatsopano zopangira ma capacitor kuti ziyendetse bwino ntchito zogwiritsira ntchito ma semiconductor a m'badwo wachitatu

Chidziwitso Chofunikira cha PCIM

Shanghai, Seputembala 25, 2025—Lero nthawi ya 11:40 AM, pa PCIM Asia 2025 Technology Forum ku Hall N4 ya Shanghai New International Expo Center, a Zhang Qingtao, Wachiwiri kwa Purezidenti wa Shanghai YMIN Electronics Co., Ltd., adapereka nkhani yayikulu yotchedwa "Kugwiritsa Ntchito Ma Capacitors Mwatsopano mu Mayankho Atsopano a Semiconductor a M'badwo Wachitatu."

Nkhaniyi inayang'ana kwambiri pa zovuta zatsopano zomwe zimayambitsidwa ndi ukadaulo wa semiconductor wa m'badwo wachitatu monga silicon carbide (SiC) ndi gallium nitride (GaN) wa ma capacitor omwe amagwira ntchito mopitirira muyeso monga ma frequency ambiri, magetsi ambiri, ndi kutentha kwambiri. Nkhaniyi inayambitsa mwadongosolo njira zamakono za ma capacitor a YMIN komanso zitsanzo zothandiza pakukwaniritsa kuchuluka kwa capacitance, ESR yochepa, moyo wautali, komanso kudalirika kwambiri.

Mfundo Zofunika

Ndi kugwiritsa ntchito mwachangu zida za SiC ndi GaN m'magalimoto atsopano amphamvu, malo osungira mphamvu a photovoltaic, ma seva a AI, magetsi a mafakitale, ndi madera ena, zofunikira pakugwira ntchito kwa ma capacitor othandizira zikukulirakulira. Ma capacitor salinso othandizira ntchito zokha; tsopano ndi "injini" yofunika kwambiri yomwe imatsimikiza kukhazikika, kugwira ntchito bwino, komanso moyo wautali wa dongosolo. Kudzera mu luso la zinthu, kukonza kapangidwe kake, ndi kukweza njira, YMIN yapeza kusintha kwakukulu kwa ma capacitor m'magawo anayi: voliyumu, mphamvu, kutentha, ndi kudalirika. Izi zakhala zofunikira kwambiri pakugwiritsa ntchito bwino ntchito za semiconductor za m'badwo wachitatu.

Mavuto aukadaulo

1. Yankho la Mphamvu ya AI Server · Kugwirizana ndi Navitas GaN. Mavuto: Kusintha kwa ma frequency apamwamba (>100kHz), mphamvu ya ripple yapamwamba (>6A), ndi malo otentha kwambiri (>75°C). Yankho:Mndandanda wa IDC3Ma capacitor a electrolytic otsika a ESR, ESR ≤ 95mΩ, ndi moyo wa maola 12,000 pa 105°C. Zotsatira: Kuchepa kwa 60% pa kukula konse, kusintha kwa magwiridwe antchito ndi 1%-2%, ndi kuchepetsa kutentha ndi 10°C.

2. NVIDIA AI Server GB300-BBU Backup Power Supply · Kulowa m'malo mwa Musashi waku Japan. Mavuto: Kukwera kwa mphamvu ya GPU mwadzidzidzi, kuyankha kwa millisecond, komanso kuwonongeka kwa moyo m'malo otentha kwambiri. Yankho:Ma supercapacitor a LIC square, kukana kwamkati <1mΩ, ma cycle miliyoni 1, ndi kuyitanitsa mwachangu kwa mphindi 10. Zotsatira: Kutsika kwa kukula ndi 50%-70%, kuchepa kwa kulemera ndi 50%-60%, ndi kuthandizira mphamvu yayikulu ya 15-21kW.

3. Infineon GaN MOS480W Sitima Yamagetsi Yosinthana ndi Rubycon yaku Japan. Mavuto: Kutentha kwakukulu kogwira ntchito kuyambira -40°C mpaka 105°C, kukwera kwamphamvu kwa ripple current. Yankho: Kuchepa kwa kutentha kwambiri <10%, kupirira kwa ripple current ya 7.8A. Zotsatira: Yadutsa -40°C yoyambira kutentha kochepa komanso mayeso a kutentha kochepa okhala ndi chiwongola dzanja cha 100%, kukwaniritsa zosowa za makampani oyendetsa sitima kwa zaka zoposa 10.

4. Galimoto Yatsopano YamagetsiMa Capacitor a DC-Link· Yogwirizana ndi chowongolera cha mota cha 300kW cha ON Semiconductor. Mavuto: Kusinthasintha kwa ma frequency > 20kHz, dV/dt > 50V/ns, kutentha kwa mlengalenga > 105°C. Yankho: ESL < 3.5nH, moyo wautali > maola 10,000 pa 125°C, ndi 30% yowonjezera mphamvu pa voliyumu iliyonse. Zotsatira: Kugwira ntchito bwino konse > 98.5%, kuchuluka kwa mphamvu kupitirira 45kW/L, ndi moyo wa batri wawonjezeka ndi pafupifupi 5%. 5. GigaDevice 3.5kW Charging Pile Solution. YMIN imapereka chithandizo chakuya.

Mavuto: Mafupipafupi osinthira a PFC ndi 70kHz, mafupipafupi osinthira a LLC ndi 94kHz-300kHz, mafunde a ripple a mbali yolowera amakwera kufika pa 17A, ndipo kukwera kwa kutentha kwapakati kumakhudza kwambiri moyo wamagetsi.
Yankho: Kapangidwe ka multi-tab parallel kamagwiritsidwa ntchito kuchepetsa ESR/ESL. Pophatikizidwa ndi zida za GD32G553 MCU ndi GaNSafe/GeneSiC, mphamvu ya 137W/in³ imakwaniritsidwa.
Zotsatira: Kugwiritsa ntchito bwino kwa makina ndi 96.2%, PF ndi 0.999, ndipo THD ndi 2.7%, zomwe zimakwaniritsa kudalirika kwakukulu komanso zaka 10-20 zomwe zimagwiritsidwa ntchito pochaja magalimoto amagetsi.

Mapeto

Ngati mukufuna kugwiritsa ntchito makina amakono a semiconductors a m'badwo wachitatu ndipo mukufuna kudziwa momwe njira zatsopano zopangira ma capacitor zingathandizire magwiridwe antchito a makina ndikulowa m'malo mwa makampani apadziko lonse lapansi, chonde pitani ku YMIN booth, C56 ku Hall N5, kuti mukambirane mwatsatanetsatane zaukadaulo!
