40V Gen-7 eGaN FET powers 50A RMS three-phase inverter board

The EPC91121 motor drive inverter evaluation board from Efficient Power Conversion (EPC) is a three-phase inverter platform built around the Gen-7 EPC2366 40 V eGaN® power transistor for prototyping motor-drive designs in drones, robotics, industrial automation and handheld power tools. The 79 mm × 80 mm board operates from 18 V to 30 V inputs, delivers up to 70 Apeak or 50 ARMS output current and includes gate drivers, housekeeping power supplies, voltage and temperature monitoring, current sensing on all three phases and interfaces for shaft encoders and Hall sensors. Supporting PWM switching frequencies up to 150 kHz, the platform is designed to help engineers evaluate high-frequency GaN motor-control systems with reduced magnetic size, lower switching losses and compatibility with controller platforms from Renesas, Microchip, Texas Instruments and STMicroelectronics.
