GaN Systems signs aerospace three-phase power deal
GaN Systems has signed a strategic partnership with Aveox to significantly reduce the size and weight of three-phase AC power converters with Active Power Factor Correction (APFC) in aerospace applications.

The deal enables the development of the world’s most power-dense, Aerospace-Compliant power conversion modules for a wide variety of cockpit, galley and cabin equipment that uses three phase power.  

Aveox’s high-efficiency power conversion modules for aerospace and defence systems are replacing legacy Transformer Rectifier Units (TRUs) around the world. GaN Systems’ power devices allow the modules to be more than five times smaller than conventional units using silicon technology. GaN switches have very low losses which enable an efficiency of over 97 per cent, significantly reducing the amount of heat generated. Using compact GaNpx bottom-cooled devices, Aveox was able to combine both the semiconductor switches and surface-mounted magnetics onto a single Insulated Metal Substrate (IMS) board, making the converter smaller than before possible. 

The power density of 10 KW/kg and compliance with stringent RTCA DO-160 power quality requirements support 'simple electronics' architecture as defined per DO-254 and ABD Sec 1.8 which reduces certification costs

“Running GaN Systems devices at high frequency has enabled us to significantly reduce the size and weight of our newest generation power conversion modules, said David Palombo, CEO of Aveox. “Together with GaN Systems, we are excited to see our advanced technologies enable leading aerospace companies to develop some of the world’s most efficient and lightest weight power systems for safety critical applications.”

“We are excited to be working with leading companies like Aveox and seeing the growing number of innovative, state-of-the-art GaN-based products released in the market, especially in industries where durability and reliability count,” said Jim Witham, CEO of GaN Systems. “With this partnership, we are seeing how GaN Systems is playing a pivotal role in providing an innovative energy-efficient solution. Most noticeably, there is a significant amount of momentum in various markets, as more companies realize the outcomes with GaN to enable smaller, lower cost, energy-efficient power systems.”
