Isi ihe PCIM
Shanghai, Septemba 25, 2025—N'elekere 11:40 nke ụtụtụ taa, na PCIM Asia 2025 Technology Forum na Hall N4 nke Shanghai New International Expo Center, Maazị Zhang Qingtao, osote onye isi oche nke Shanghai YMIN Electronics Co., Ltd., kwuru okwu isi okwu nke akpọrọ "Ngwa ọhụrụ nke Capacitors na Ngwọta Semiconductor ọgbọ ọhụrụ."
Okwu a lekwasịrị anya n'ihe ịma aka ọhụrụ ndị teknụzụ semiconductor nke ọgbọ nke atọ dị ka silicon carbide (SiC) na gallium nitride (GaN) na-eweta maka capacitors n'okpuru ọnọdụ ọrụ dị oke njọ dịka ugboro ugboro, voltaji dị elu, na okpomọkụ dị elu. Okwu a gosipụtara ọganihu teknụzụ YMIN capacitors na ihe atụ bara uru n'inweta njupụta capacitance dị elu, obere ESR, ogologo ndụ, na ntụkwasị obi dị elu.
Isi Ihe Ndị Dị Mkpa
Site na nnabata ngwa ngwa nke ngwaọrụ SiC na GaN n'ime ụgbọ ala ike ọhụrụ, nchekwa ike fotovoltaic, sava AI, ọkọnọ ike ụlọ ọrụ, na mpaghara ndị ọzọ, ihe achọrọ maka arụmọrụ maka nkwado capacitors na-aghọwanye ihe siri ike. Capacitors abụghịzi naanị ịkwado ọrụ; ha bụ ugbu a "engine" dị mkpa nke na-ekpebi nkwụsi ike, arụmọrụ, na ogologo oge nke sistemụ. Site na ihe ọhụrụ ihe onwunwe, mmezi nhazi, na mmelite usoro, YMIN enwetala mmezi zuru oke na capacitors n'ofe akụkụ anọ: olu, ikike, okpomọkụ, na ntụkwasị obi. Nke a aghọwo ihe dị mkpa maka mmejuputa ngwa semiconductor nke ọgbọ nke atọ nke ọma.
Ihe ịma aka teknụzụ
1. Ngwọta Ike nke Ihe nkesa AI · Mmekọrịta na Navitas GaN. Ihe ịma aka: Mgbanwe ugboro ugboro dị elu (>100kHz), ọkụ eletrik dị elu (>6A), na gburugburu okpomọkụ dị elu (>75°C). Ngwọta:Usoro IDC3Ike eletriki ESR dị ala, ESR ≤ 95mΩ, na ndụ nke awa 12,000 na 105°C. Nsonaazụ: Mbelata 60% na nha zuru oke, mmụba arụmọrụ 1%-2%, na mbelata okpomọkụ 10°C.
2. NVIDIA AI Server GB300-BBU Nkwado Ike · Ịdochi Musashi nke Japan. Ihe ịma aka: Mmụba ike GPU mberede, nzaghachi ọkwa millisecond, na mmebi ndụ na gburugburu okpomọkụ dị elu. Ngwọta:Ndị isi ike nke LIC square, iguzogide ime <1mΩ, okirikiri nde 1, na chaja ngwa ngwa nkeji iri. Nsonaazụ: Mbelata 50%-70% na nha, mbelata 50%-60% na ibu, na nkwado maka ike kacha elu 15-21kW.
3. Infineon GaN MOS480W Rail Power Supply Na-anọchi Japanese Rubycon. Ihe ịma aka: Oke okpomọkụ ọrụ sara mbara nke -40°C ruo 105°C, mmụba nke ọkụ eletrik na-agbagharị ugboro ugboro. Ngwọta: Oke mbelata okpomọkụ dị ala <10%, ike iguzogide ọkụ eletrik nke 7.8A. Nsonaazụ: Mmalite okpomọkụ dị ala -40°C gafere na ule okirikiri okpomọkụ dị ala nke nwere ọnụego ngafe 100%, na-emezu ihe achọrọ maka ụlọ ọrụ ụgbọ okporo ígwè maka afọ 10+.
4. Ụgbọala Ike ỌhụrụNdị na-enye DC-Link Capacitors· Dakọtara na njikwa moto 300kW nke ON Semiconductor. Ihe ịma aka: Ugboro mgbanwe > 20kHz, dV/dt > 50V/ns, okpomọkụ gburugburu > 105°C. Ngwọta: ESL < 3.5nH, ndụ > awa 10,000 na 125°C, na ikike amụbawanye 30% kwa olu otu. Nsonaazụ: Arụmọrụ zuru oke > 98.5%, njupụta ike gafere 45kW/L, na ndụ batrị mụbara site na ihe dị ka 5%. 5. Ngwọta Nchaji GigaDevice 3.5kW. YMIN na-enye nkwado miri emi.
Ihe ịma aka: Ugboro mgbanwe PFC bụ 70kHz, ugboro mgbanwe LLC bụ 94kHz-300kHz, mmụba nke ikuku ripple n'akụkụ ntinye ruo ihe karịrị 17A, mmụba nke okpomọkụ isi na-emetụta ndụ nke ukwuu.
Ngwọta: A na-eji usoro nhazi multi-tab iji belata ESR/ESL. Ijikọta ya na ngwaọrụ GD32G553 MCU na GaNSafe/GeneSiC, a na-enweta njupụta ike nke 137W/in³.
Nsonaazụ: Ọkwa kachasị elu nke sistemụ bụ 96.2%, PF bụ 0.999, na THD bụ 2.7%, na-emezu ihe achọrọ maka ntụkwasị obi dị elu na ndụ afọ 10-20 nke ọdụ chaja ụgbọala eletrik.
