650 V GaN in Aircraft Switch Mode Power Supplies

PublishTime：2021-12-08

■International aviation electronics supplier AES serves the industry's most trusted names in commercial flying. The company recently disrupted its industry with the release of the first GaN-based switch mode power supplies. These PSUs offer at minimum a 10 percent increase in efficiency versus competitive products, one representing unprecedented cooling functionality. They are currently used in large passenger airplanes such as the Airbus A318-A321 planes, Boeing B767 and B787 VIP planes, and others.
■AES' flagship GaN PSU—the 500 W PS250X—is the aviation industry's first passively cooled power supply at 420 W. It uses Transphorm's GaN FETs in a single-phase CCM boost power factor correction (PFC) topology.
■The second PSU—the 1200 W PS6120—deploys Transphorm’s GaN in a fan-cooled, three-phase CCM boost PFC topology.
■Both products are DO-160 compliant—meeting the stringent 25-point+ standard of the Radio Technical Commission for Aeronautics (RTCA). This standard assesses system impact and performance under various external and internal aircraft conditions.
