美國加州聖荷西--(BUSINESS WIRE)--十一月 4, 2024--
(美國商業資訊)-- Power Integrations (NASDAQ： POWI ) 這家節能型功率轉換領域的高壓積體電路領導廠商，今日宣布推出其 InnoMux™-2 系列的 單級、獨立穩壓多路輸出離線式電源供應器 IC 的新成員。新裝置採用了業界首款透過該公司專有 PowiGaN™ 技術製造的 1700 V 氮化鎵切換開關。1700 V 的額定值進一步提升 GaN 功率裝置的水準，此前的水準標竿由 Power Integrations 自己的 900 V 和 1250 V 裝置 (均於 2023 年推出) 樹立。 1700 V InnoMux-2 IC 輕鬆支援返馳式結構中的 1000 VDC 標準輸入電壓，在需要一個、兩個或三個供應電壓的應用中實現了 90% 以上的效率。每個輸出都經過調節 (精確到 1% 以內)，無需採用後端穩壓器，還進一步將系統效率提高約 10%。這款新裝置在汽車充電器、太陽能變頻器、三相計量表和各種工業電源系統等電源供應器應用中取代了昂貴的碳化矽 (SiC) 電晶體。

Power Integrations 技術副總裁 Radu Barsan 表示：「在不到兩年的時間內，我們快速發展的 GaN 實現了三個世界第一的電壓額定值：900 V、1250 V 和現在的 1700 V。我們的新型 InnoMux-2 IC 結合了 1700 V GaN 和其他三項最新創新：獨立、準確、多路輸出調節；FluxLink™二次側調節 (SSR) 數位隔離通訊技術；以及不需要有源鉗位的零電壓切換 (ZVS)。它幾乎消除了切換損失。」
Yole Group 化合物半導體活動主管 Ezgi Dogmus 表示：「1700 V 額定值遠高於我們所知的任何其他商用 GaN HEMT」。「功率 GaN 裝置市場有望在十年內達到 20 億美元，擴展到各種應用領域，具有比 SiC 更具吸引力的潜在成本優勢。」(1)

EDITORS/NEWS DIRECTORS:
The best young spellers in the English language are competing at the Scripps National Spelling Bee this week, continuing a more than century-old tradition. The three-day competition began Tuesday and concludes Thursday night.
This year's 247 spellers represent 50 states, the District of Columbia, three U.S. territories and five other countries. They competed in preliminary rounds on May 26, quarterfinals and semifinals are happening today, and finals tomorrow, with the winner taking the unofficial crown of top speller in the English language. The champion's haul includes a trophy and more than $52,000 in cash and prizes.
After the preliminary rounds on Tuesday, 167 were left, and that field was cut to 95 quarterfinalists after a written spelling and vocabulary test.
The top returning finisher from 2025 is Sarv Dharavane of Dunwoody, Georgia, who finished third last year as an 11-year-old fifth-grader and got a perfect score on the written test. Even if he falls short this year, he has two years of eligibility left.
Three other potential contenders had perfect test scores:
— Shrey Parikh, a 14-year-old eighth-grader from Rancho Cucamonga, California, who finished third in 2024. He has dominated the bee circuit in the past year, winning the South Asian Spelling Bee, the SpellPundit National Spelling Bee and the Words of Wisdom Spelling Bee.
— Oliver Halkett, a 14-year-old eighth-grader from Los Angeles who finished in a tie for seventh last year.
— Esha Marupudi, a 14-year-old eighth-grader from Chandler, Arizona, who also tied for seventh last year.
Spellers can compete through the eighth grade, and this year's competitors range in age from 9 to 15. Faizan Zaki won last year's bee and will return in a ceremonial role; past champions are not allowed to compete again and last year's runner-up aged out of the competition. The bee moved this year to a new venue, Constitution Hall in downtown Washington, after more than a decade at a convention center just outside the city in Oxon Hill, Maryland. Mina Kimes, an NFL analyst for ESPN and the recent “Celebrity Jeopardy!” champion, is serving as the television host, the bee's first celebrity host since LeVar Burton in 2022.
