GaN-Based Power Converter Ecosystem Design: Magnetics, Gate Driver IC, and Applications


Yaow-Ming Chen, Yu-Chen Liu, Ching-Jan Chen, and Katherine Kim


The power density and efficiency demand of power converters keep increasing in applications such as data centers, vehicles, satellite, and renewable energy system. As demonstrated by industry and academy, GaN switch becomes a game changing device to meet such demands. However, to fully use the potential of GaN-based power converter, an ecosystem including magnetics, gate driver IC, and converter implementation have to be designed together. This tutorial will cover high-frequency converter design and magnetics in the first part, high-speed gate driving design in the second part, and converter applications using GaN switches in the third part. The presentation will introduce each of these main concepts and give concrete examples and experimental results.
