Abstract

The LAIC laboratory of CEA-LETI's Systems Department in Grenoble is specialized in the development of innovative electronic and mechatronic systems, taking into account challenges linked to energy recovery / management / transmission and sensor integration in a variety of environments. As part of the development of its R&D activities, the LAIC is offering a PhD thesis on wireless power transmission using GaN-based resonant inductive coupling.

Wireless power transmission technologies are booming, with applications in space, consumer electronics, medical, automotive and defense sectors. Power transmission technology using resonant inductive coupling appears to be the most promising in terms of near-field efficiency.

The proposed thesis will follow the development of a system including a fixed-coupling electromagnetic coupler and HF electronics based on a GaN transistor-based class-E topology. In this context, the aim of the thesis is to develop a system robust to coupler coil misalignment. The aim is to study, develop and test the performance of a new coupler and an adaptive drive electronics. The candidate will be required to develop analytical and numerical models to optimize the electronics, compare the performance of existing systems in the literature, and propose, develop and test the performance of innovative GaN-based topologies ensuring good robustness to electromagnetic coupling variation.

A multi-disciplinary profile with a focus on power electronics and physics is required for this thesis. In addition to a solid theoretical ground and strong simulation skills, the PhD student will need to be able to work as part of a team, with an aptitude for experimentation and an attraction for practical applications.
