GaN Devices for Smaller, Lighter, Smoother Motor Drives

GaN Devices for Smaller, Lighter, Smoother Motor Drives

Today, the permanent magnet motor, also known as DC brushless motor (BLDC), is widely used and offers higher torque capability per cubic inch and higher dynamics when compared to other motors. So far, silicon-based power devices have been dominant in the inverter electronics, but today their performance is nearing their theoretical limits. There is an increasing need for higher power density. Gallium nitride (GaN) transistors and ICs have the best attributes to satisfy these needs.

The Power and Evolution of GaN, Part 6: GaN Technology Adoption and Roadmap

The Power and Evolution of GaN, Part 6: GaN Technology Adoption and Roadmap

In the final installment of this series, how GaN has met the requirements to displace silicon is explored. As the adoption rate of GaN explodes, it is important to remember that, while GaN has made many advancements in just a few short years, it is still far from its theoretical performance limitations and thus there are profound improvements that can continue to be achieved. In time, the performance and cost advantages of GaN-on-silicon will result in a majority of applications currently using silicon-based devices converting to the smaller, faster, cheaper, and more reliable GaN technology.
