This video is a review of the EPC91122, a compact GaN-based three-phase BLDC motor drive inverter optimized for humanoid robot joints and other space-constrained actuators. Built around the EPC33110 co-packaged GaN module, it combines power stage, gate drivers, sensing, control, and communication on a single circular board. With an onboard STM32 microcontroller, magnetic encoder, precise current and voltage sensing, and RS‑485/JTAG interfaces, it delivers high efficiency, fast dynamic response, and robust performance for advanced robotics.
