Infineon — 100 V GaN Transistors

Infineon CoolGaN™ 100 V G3 Transistors

CoolGaN™: redefining efficiency, precision, and size

Humanoid robots are emerging as game changing tools across industries, from manufacturing environments to assisting healthcare professionals in patient care. As deployment expands across multiple segments, humanoid robots require accurate and reliable power solutions. A single humanoid robot can include more than 70 joints and up to 600 power switches. Selecting the right power switch technology is therefore critical.
 

Why CoolGaN™ for Humanoid Robots and Adjacent Applications?

Infineon’s CoolGaN™ Transistors deliver advanced motor control performance for humanoid robots, cobots, and other robotic systems. Designed for peak efficiency, compactness, and precision, CoolGaN™ technology provides system level advantages across four key areas.

Small and Light
Smaller bulk capacitance, typically defined by DC bus ripple, enables the use of ceramic capacitors with lower ESR. Reduced overall inverter losses allow for smaller heatsinks and support integration of the drive and motor into more compact assemblies.

Cool
Lower switching losses generate less heat, helping reduce motor temperature or enabling higher output power at the same temperature. This makes CoolGaN™ ideal for temperature critical designs, including systems with touchable surfaces.

Fast and Accurate
Typical control loop frequency less than or equal to PWM frequency enables higher control loop bandwidth and faster motor response. Lower torque ripple supports highly accurate motion control applications.

Highly Efficient
Fast switching frequency increases overall system efficiency. Reduced bus capacitor ESR losses contribute to extended battery life in low voltage motor systems.

Infineon’s CoolGaN™ technology is at the forefront of next generation robotics, redefining what battery powered low voltage motors can achieve and empowering advanced humanoid and robotic designs.
