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.

Building the Smallest and Most Efficient 48 V to 5 - 12 V DC to DC using eGaN FETs and ICs

The Power and Evolution of GaN – Part 2 of 6 part series

With the power architecture transition from a 12 V to a 48 V bus power distribution in modern data centers, there is an increased demand to improve 48 V power conversion efficiency and power density. In this context, DC-DC converters designed using eGaN® FETs and ICs provide a high efficiency and high power density solution. Additionally, with the advent of 48 V power systems in mild-hybrid, hybrid and plug-in hybrid electric vehicles, GaN transistors can provide a reduction in size, weight, and Bill of Materials (BOM) cost.

基氮化鎵功率元件如何把矽基功率MOSFET逐出?

專為高效電源轉換而設的氮化鎵功率電晶體已經投產7年多了。全新的市場例如雷射雷達、波峰追蹤及無線電源,都成為氮化鎵的新興市場,因為氮化鎵具備超高速的的開關速度。這些市場使得氮化鎵產品得以量產、成本更低及具備優越的可靠性。這些優勢為比較保守的設計工程師提供更大的利好條件,因此,DC/DC轉換器工程師、AC/DC轉換器及車載應用工程師都開始對氮化鎵器件進行評估。要把120億美元的矽基MOSFET市場轉為氮化鎵市場,還有什麼壁壘呢?就是信心的問題。設計工程師、製造工程師、採購經理及管理層都必需對氮化鎵技術的優勢有足夠的信心、相信氮化鎵技術可以解決設計師對採用全新技術的風險的疑問。讓我們看看3個主要構成風險的因素:供應鏈、成本及產品的可靠性。

The Growing Ecosystem for eGaN FET Power Conversion

In recent years, GaN-based power conversion has increased in popularity due to the inherent benefits of eGaN FETs over conventional Si transistors. Migrating a converter design from Si to GaN offers many system-level improvements, which require consideration of all the components in that system. This trend has subsequently spurred a growth in the ecosystem of power electronics that support GaN-based designs.

eGaN FET-Based Synchronous Rectification

As GaN-on-Si becomes more common in DC-DC converter designs, questions often arise from experienced designers about the impact of the unique characteristics of GaN transistors when used as synchronous rectifiers (SRs). In particular, the third quadrant off-state characteristics, better known as “body diode” conduction in Si MOSFETs, which is activated during converter dead-time, is of interest. For this article, the focus will be on the similarities and differences of Si MOSFETs and eGaN® FETs when operated as a “body diode” and outline their relative advantages and disadvantages.
