ABSTRACT

Wireless power transmission (WPT) technologies are booming with applications in the aerospace, consumer electronics, medical, automotive and defense sectors. The purpose of these technologies is to transmit electrical energy between two elements without using a physical medium with the maximum possible efficiency. Power transmission technology using resonant inductive coupling seems to be the most promising in terms of near-field efficiency. This thesis is part of the development of the thematic on wireless power transmission and power at CEA-LETI in Grenoble.In this context, the objective of the thesis is to study, develop and test the performances of this technology over the VHF frequency range (30-300 MHz) unexploited in the literature, by integrating GaN transistor-based electronics. The candidate will develop analytical and numerical models to optimize the electromagnetic coupler, compare the performances of existing systems in the literature, and propose, develop and test the performances of innovative GaN-based topologies. The final goal of the thesis is the analysis and understanding of the advantages and limitations of this technology compared to the lower frequencies traditionally used.A multidisciplinary profile oriented towards power physics and electronics is sought for this thesis. In addition to a solid theoretical background, the PhD student will need to possess teamwork skills and an aptitude for experimentation. The PhD student will be integrated in CEA-Leti's Systems Department, within teams of researchers with strong skills in the development and optimization of power and wireless power transmission systems.
