EPC Space – GaN in Space Applications (02/2025)

Gallium Nitride (GaN) technology is transforming power electronics for space applications, delivering higher efficiency, reduced size, and enhanced performance in demanding environments.

High-Efficiency DC/DC Converters
GaN-based DC/DC converters provide smaller, more efficient power solutions with proven space heritage. These converters offer superior efficiency and power density, essential for next-generation spacecraft systems.

Space Systems Lidar
Lidar systems serve as the “eyes” for autonomous navigation, docking, and robotic operations in space. The shorter the laser pulse, the higher the resolution of lidar images. GaN devices enable faster switching speeds, increased efficiency, and reduced system size, making them ideal for space-based lidar applications.

Space Motor Drives
Brushless DC (BLDC) motors play a critical role in space robotics and automated instrumentation. Reaction wheels, essential for satellite attitude control, rely on radiation-hardened GaN solutions to improve precision and reduce weight. GaN power devices provide compact, lightweight, and highly efficient motor drive solutions capable of withstanding the harsh conditions of space.

Space Systems – Ion Thrusters
Ion thrusters are a key technology for spacecraft propulsion, enabling satellite orientation, positioning, and interplanetary missions. Radiation-hardened GaN power solutions enhance power supply efficiency, making these systems smaller, lighter, and more powerful for long-duration space travel.

GaN technology is shaping the future of space exploration, offering compact, lightweight, and highly efficient solutions for next-generation space systems.
