Design Guide: Architecture & Design Solutions of Robotics With GaN

Robotics is an interdisciplinary field with a strong focus on integration and system optimization. Applications include service robots, collaborative as well as industrial robots, autonomous drones, and automated guided vehicles. An optimized design of the motors and drives in these robotic applications is key for a successful end-product. In a conventional, silicon-based (Si) design, there is always a trade-off between size and efficiency. For example, smaller size for components such as filters or DC link capacitance can be achieved with higher switching frequency at the cost of increased switching loss. However, with the recent introduction of gallium-nitride (GaN) high electron mobility transistors (HEMT) in the landscape of power electronics, new design possibilities have been emerging, and the long-standing trade-off between efficiency vs. size seems to be possible to overcome.
