EPC has launched the EPC91122, a three-phase BLDC motor drive inverter evaluation board aimed at humanoid robot joints and e-mobility. The board operates within a 15 to 65 VDC input range and can deliver up to 20 ARMS phase current in pulsed operation.
It integrates a GaN-based power stage with a maximum voltage of 100 V, featuring low RDS(on) values and supporting switching frequencies up to 150 kHz. The design includes a microcontroller for PWM generation and feedback processing, current sensing, and communication interfaces. The board is intended to help designers reduce mechanical and electrical constraints in joint drives and is available as a reference design.
