In this episode of GaN Talk, host Maurizio Di Paolo Emilio dives into the challenges of embedding motor drives directly inside humanoid robot joints. The spotlight is on EPC’s new EPC91122 circular inverter board, designed to fit inside the motor housing and enable extreme power density and fast dynamic response. Joined by Marco Palma, Director of Motor Drive Systems and Applications at EPC, the discussion highlights how the board integrates control, sensing, communication and power stage around the EPC33110 GaN three-phase power module. The episode explains how high-frequency switching and deep integration made possible by gallium nitride technology are reshaping robotics beyond the limits of traditional silicon drives.
