The Newcastle University research output collection, currently available on ePrints, will shortly be moving to a new open repository platform, Figshare. To prepare for the data migration we have paused adding new content to ePrints, and will resume once the new repository is launched. During this time you will continue to have access to ePrints (but no new content will appear). We will share updates here when available.

Abstract

Two-way wireless power transfer (WPT) shows advantages to share energy via air without employing cable connection. This paper presents a study on a proposed GaN-based bidirectional wireless power converter for a battery to battery system using resonant inductive coupling technique. This power converter is built and tested that enables to wirelessly transfer power up to 45W at the frequency of 0.5Mhz. By varying the aligned distance, lateral and angular misalignment of coils, the influence of the relative positions to the self and mutual inductance of two coils as well as operation and efficiency of power converter has been thoroughly investigated and discussed.
