Inside EPC’s GaN Roadmap: Motor Systems for Next-Generation Robots

This interview with Marco Palma, Vice President of Motor Systems at EPC, explores how GaN technology is reshaping motor drives for humanoid robots and drones. Palma discusses the EPC 91132 reference board based on the EPC33110 IC, highlighting high power density, compact form factors, and advanced thermal management via topside cooling. He explains the importance of PWM frequency, dead time, and control algorithms, and outlines EPC’s scalable GaN inverter portfolio and future trends such as multi-phase motors and fully integrated GaN power ICs.
