EPC optimizes new GaN-based motor drive for humanoid robots [Video]

Efficient Power Conversion Corp., or EPC, this week launched EPC91104, a high-performance, three-phase brushless DC motor drive inverter reference design. The company said this design is suitable for powering compact, precision motors in humanoid robots, such as those used for wrist, finger, and toe movements.

“Humanoid robots demand motors with precision and compactness, and the EPC91104 is specifically designed to meet those needs for applications like small joint actuation,” said Alex Lidow, CEO of EPC.

EPC is a developer of enhancement-mode gallium nitride (eGaN) power devices. Founded in 2007, the company said its eGaN technology enables it to advance new applications and industries.

It said silicon has hit its physical limits and, therefore, is no longer able to stay ahead of demand for more and more efficient power. GaN technology offers significant advantages over traditional silicon-based devices, including higher efficiency, faster switching speeds, and smaller size, EPC said.

New board offers efficiency, says EPC
