Power Semiconductors for High Efficiency Applications

Enabling wireless power amplifiers and power converters for solar energy and smart grid applications.

PI: Peter Asbeck and Paul Yu | International Partner: KETI

The project will develop semiconductor device and circuit technology to provide efficient power converters, with particular focus on high frequency operation (for rapid response and for minimization of external inductors and capacitors) and high output accuracy (for low spurious outputs). The technology application focus will be applied to wireless communications, particularly power amplifiers, and to power converters for solar energy and smart grid applications. Technologies will be explored to improve over conventional Si MOSFETs for these applications with the use of III-V semiconductors, particularly GaN.
