This work investigates the advantages of GaN-based integrated motor drives for low-voltage robotic applications, with particular focus on humanoid robot joints and drone motors. The thesis is organized into three main parts: (i) a review of robotic applications and GaN Monolithic Power Integrated Circuits, (ii) the design of a motor-drive inverter board based on the EPC33110, and (iii) the experimental validation of the developed evaluation board. The first part reviews advanced robotic systems, from humanoid robots to Unmanned Aerial Vehicles (UAVs), highlighting the growing importance of power converters in enabling higher efficiency, compactness, and performance. The adoption of Wide-Bandgap (WBG) semiconductors, especially GaN devices, is transforming integrated motor-drive design thanks to their high switching speed, low conduction and switching losses, high power density, and elevated operating temperature capability.
