PCIM Cov Lus Qhia Tseem Ceeb
Shanghai, Cuaj Hlis 25, 2025—Thaum 11:40 AM hnub no, ntawm PCIM Asia 2025 Technology Forum hauv Hall N4 ntawm Shanghai New International Expo Center, Mr. Zhang Qingtao, Tus Lwm Thawj Coj ntawm Shanghai YMIN Electronics Co., Ltd., tau hais lus tseem ceeb hu ua "Innovative Applications of Capacitors in New Third-Generation Semiconductor Solutions."
Cov lus hais tau tsom mus rau cov teeb meem tshiab uas tshwm sim los ntawm cov thev naus laus zis semiconductor tiam peb xws li silicon carbide (SiC) thiab gallium nitride (GaN) rau cov capacitors nyob rau hauv cov xwm txheej ua haujlwm hnyav xws li zaus siab, hluav taws xob siab, thiab kub siab. Cov lus hais tau qhia txog kev tshawb fawb txog kev siv tshuab ntawm YMIN capacitors thiab cov piv txwv ua tau zoo hauv kev ua tiav qhov muaj peev xwm loj, ESR qis, lub neej ntev, thiab kev ntseeg siab siab.
Cov Ntsiab Lus Tseem Ceeb
Nrog rau kev siv cov khoom siv SiC thiab GaN sai sai hauv cov tsheb fais fab tshiab, kev khaws cia lub zog photovoltaic, AI servers, cov khoom siv fais fab kev lag luam, thiab lwm yam teb, cov kev cai ua tau zoo rau kev txhawb nqa cov capacitors tau dhau los ua qhov nruj dua. Capacitors tsis yog tsuas yog lub luag haujlwm txhawb nqa xwb; lawv tam sim no yog lub "cav" tseem ceeb uas txiav txim siab qhov ruaj khov, kev ua haujlwm zoo, thiab lub neej ntev ntawm lub kaw lus. Los ntawm kev tsim kho tshiab ntawm cov khoom siv, kev tsim kho kom zoo, thiab kev txhim kho cov txheej txheem, YMIN tau ua tiav kev txhim kho tag nrho hauv cov capacitors hla plaub qhov ntev: ntim, peev xwm, kub, thiab kev ntseeg siab. Qhov no tau dhau los ua qhov tseem ceeb rau kev siv cov ntawv thov semiconductor tiam thib peb.
Cov Kev Sib Tw Txuj Ci
1. Kev daws teeb meem AI Server Power Supply · Kev koom tes nrog Navitas GaN. Cov teeb meem: Kev hloov pauv zaus siab (>100kHz), tam sim no siab (>6A), thiab qhov chaw kub siab (>75°C).

Cov txiaj ntsig: txo 60% ntawm qhov loj tag nrho, txhim kho kev ua haujlwm 1%-2%, thiab txo qhov kub thiab txias 10 ° C.
2. NVIDIA AI Server GB300-BBU Lub Hwj Chim Rov Qab · Hloov Nyiv Musashi. Cov Teeb Meem: GPU lub zog nce siab tam sim ntawd, kev teb millisecond-level, thiab kev puas tsuaj ntawm lub neej nyob rau hauv qhov chaw kub siab. Kev daws teeb meem:LIC square supercapacitors, kev tiv thaiv sab hauv <1mΩ, 1 lab lub voj voog, thiab them sai 10 feeb. Cov txiaj ntsig: Txo qhov loj me 50%-70%, Txo qhov hnyav 50%-60%, thiab txhawb nqa lub zog siab tshaj plaws 15-21kW.
3. Infineon GaN MOS480W Rail Power Supply Hloov Japanese Rubycon. Cov Teeb Meem: Kev ua haujlwm kub dav dav ntawm -40 ° C txog 105 ° C, cov zaus siab ripple tam sim no surges. Kev daws teeb meem: Ultra-low kub degradation tus nqi <10%, ripple tam sim no withstand ntawm 7.8A. Cov txiaj ntsig: Dhau -40 ° C qis-kub pib thiab siab-qis kub voj voog kev sim nrog 100% dhau tus nqi, ua tau raws li kev lag luam tsheb ciav hlau 10+ xyoo qhov yuav tsum tau ua.
4. Lub Tsheb Tshiab ZogCov Capacitors DC-Link· Sib phim nrog ON Semiconductor's 300kW lub cev muaj zog tswj. Cov teeb meem: Hloov zaus > 20kHz, dV/dt > 50V/ns, qhov kub thiab txias ib puag ncig > 105°C. Kev daws teeb meem: ESL < 3.5nH, lub neej ntev > 10,000 teev ntawm 125°C, thiab muaj peev xwm nce 30% ib chav ntim. Cov txiaj ntsig: Kev ua haujlwm zoo tag nrho > 98.5%, lub zog ceev tshaj 45kW/L, thiab lub neej roj teeb nce ntxiv kwv yees li 5%. 5. GigaDevice 3.5kW Charging Pile Solution. YMIN muab kev txhawb nqa tob.
Cov Teeb Meem: PFC hloov zaus yog 70kHz, LLC hloov zaus yog 94kHz-300kHz, input-side ripple tam sim no nce mus txog ntau dua 17A, thiab qhov kub ntawm lub plawv nce siab cuam tshuam rau lub neej ntev.
Kev daws teeb meem: Ib qho qauv sib luag ntau-tab siv los txo ESR/ESL. Ua ke nrog GD32G553 MCU thiab GaNSafe/GeneSiC cov khoom siv, lub zog ceev ntawm 137W/in³ tau ua tiav.
