Qualifying and Quantifying GaN Devices for Power Applications

Qualifying and Quantifying GaN Devices for Power Applications

It’s okay to start using gallium-nitride (GaN) devices in your new designs. GaN transistors have become extremely popular in recent years. These wide-bandgap devices have been replacing LDMOS transistors in many power applications. For example, GaN devices are broadly being adopted for new RF power amplifiers used in cellular base stations, radar, satellites, and other high-frequency applications. In general, their ability to endure higher voltages and operate at frequencies well into the millimeter-wave (mmWave) range have them replacing traditional RF power transistors in most amplifier configurations.

GaN in Space

GaN in Space

This article discussed an oft forgotten or little-noticed part of the spacecraft enabling travel into outer space---power management in the space vehicle. Wide bandgap semiconductors like gallium nitride (GaN), silicon carbide (SiC), as well as diamond, are looking to be the most promising materials for future electronic components since the discovery of silicon. These technologies, depending upon their design, offer huge advantages in terms of power capability (DC and microwave), radiation insensitivity, high temperature and high frequency operation, optical properties and even low noise capability. Therefore, wide bandgap components are strategically important for the development of next generation space-borne systems. eGaN devices are quickly gaining momentum in the space industry and we will see many more applications for them by NASA and commercial contractors in future programs like Artemis and other programs in countries around the globe pursuing efforts into Space.

數據中心的發展於2019年將進入突飛猛進的時代

根據預測,到2025年,我們的數據將會超過175 zettabyte。當發明了 5G並將最早於2020年在日本舉行的奧運採用、以及通過人工智慧(AI)及機器學習(ML)的發展,建立數據中心和其部署、以及提升目前較舊的數據中心的效能,將進入突飛猛進的時代。

我深信氮化鎵(GaN)功率電晶體是數據中心功率架構的最理想元件,因為需要小型化、高效及快速開關的元件。氮化鎵元件在具48 VIN的所有拓撲,都可以實現最高的效率。

氮化鎵正面攻擊矽功率MOSFET元件

氮化鎵正面攻擊矽功率MOSFET元件

目前的氮化鎵場效應電晶體在尺寸及性能方面以飛快的速度發展,而目前為業界樹立基準的氮化鎵元件的性能還可以提升多300倍。

最早採用氮化鎵元件的應用是利用氮化鎵的超快速開關速度,例如面向全自動駕駛車輛和無人機的雷射雷達系統、機械人,以及4G/LTE基站。氮化鎵元件的產量一直在增加,而其價格跟開關速度更慢、尺寸更大型和日益陳舊的MOSFET元件相約。因此,目前正是氮化鎵元件正面攻擊MOSET的時候!。

Will GaN and the Tesla SpaceX car survive space radiation? Yes and no.

Will GaN and the Tesla SpaceX car survive space radiation? Yes and no.

Two space travel related stories hit my desktop this week; one that rapidly generated major international headlines and one that slid very quietly onto my email screen.

The headline-hitter was the successful launch of Elon Musk’s SpaceX rocket with its payload of a Tesla sports car, complete with a dummy driver at the wheel. The second was about Gallium Nitride technology that would be suitable for space applications.

這是耗能的季節

這是耗能的季節

在2014年,美國的數據中心用上了1000億千瓦小時(KWh)能量。雪上加霜的是,這個快速增長的所需能量,大部份是由基於超過一世紀前設立的基建、非常低效的供電網路支持。浪費了的能量有多嚴重?供電網路為一個數字晶片提供150 W功率,而實際上,它可能只需要100 W。 此外,由於在電源轉換過程中,每一瓦功耗會轉化為熱量,因此實際上所浪費的能量更大。而我們必需利用昂貴及耗電的空調機來為伺服器群散熱。空調機大約需要1 W來除去1 W的功耗,這相等於已經低的能源轉換效率將再降低一倍。

全新半導體材料的出現可提高能源轉換效率,其成本也可以更低。在伺服器群中的功率結構的最後階段解決低效率的問題,可以實現每年節省70億千瓦小時的能量。如果一併計算空調機的能源成本,總成本倍增並佔了美國的所有伺服器的總能耗的14%。所能夠節省的成本也是非常巨大的。以每一千瓦小時的平均成本0.12美元來計算,每年可以節省的總成本高達17億美元,這還沒有包括由於採用更少數量的功率轉換器及空調機而得以額外節省的系統成本。
