A fast switching fast bridge using GaN transistors (2024)
Presentation / Conference Contribution
Marchant, S., & Empringham, L. (2024, December). A fast switching fast bridge using GaN transistors. Paper presented at 9th IEEE Southern Power Electronics Conference, Brisbane, Australia

This paper presents the design and evaluation of a half bridge based around off-the-shelf gallium nitride power devices and a bespoke printed circuit board. The necessary parasitic evaluation at the design stage was not straightforward due to the in... Read More about A fast switching fast bridge using GaN transistors.
