The space industry is undergoing a transformative shift to “New Space,” driven by the increasing demand for ubiquitous connectivity and the emergence of innovative business models. One of the key elements of this transformation is the adoption of gallium nitride (GaN) technology in space applications. GaN holds immense potential due to its impressive radiation hardness, high system efficiency and lightweight characteristics.

In a discussion with EE Times Europe, Taha Ayari and Aymen Ghorbel, technology and market analysts at Yole Intelligence, part of Yole Group, explained how New Space—the low Earth orbit (LEO) mission segment, with a typical satellite lifespan of three to five years and lower reliability requirements—has become a focal point for GaN adoption. As a result, power GaN devices are being adopted for various satellite systems, including DC/DC converters, point-of-load systems, motor drives and ion thrusters.

宜普電源轉換公司聯合創辦人暨執行長Alex Lidow表示，GaN的成本競爭力亦與Si MOSFET並駕齊驅，潛在爆發力更有過之而無不及，目前最關鍵就是得重塑諸多研究者的老舊觀念，認為GaN昂貴到碰不得。GaN的技術正迎來轉捩點，在先進運算、車用電子、太空電子及消費電子等新型應用設計多數採GaN技術，而非Si MOSFET。

Gallium nitride (GaN) power devices have been in production for over 10 years and, beyond just performance and cost improvements, the most significant opportunity for GaN technology to impact the power conversion market comes from the intrinsic ability to integrate multiple devices on the same substrate. This capability will allow monolithic power systems to be designed on a single chip in a more straightforward, higher efficiency, and more cost-effective way.
