Reference number : GC-2017-Q3-00654, amendment number : , agreement type : G, recipient legal name : Johnson, Thomas (The University of British Columbia), recipient country : CA, recipient province : nan, recipient city : British Columbia|Colombie-Britannique, recipient postal code : nan, program name english : Engage Plus Grants for universities, program name french : Subvention d'engagement partenarial Plus pour les universités, program purpose english : Wireless power transfer systems are an emerging technology with the aim of completely eliminating cables for_x000D_
powering electrical devices. Wireless power systems are typically limited to short distances up to 50 cm, and_x000D_
applications of the technology are broad ranging from the elimination of wiring harnesses in automobile and_x000D_
aerospace applications to powering implanted biomedical devices. One of the main challenges in wireless_x000D_
power systems is compensating for impedance changes created by spatial variation. The compensation of_x000D_
spatial impedance change is essential to obtain efficient and robust power transfer._x000D_
In this research project, wireless links with class E inverters and class E synchronous rectifiers will be_x000D_
investigated. Designs for three different frequency bands (13.56 MHz, 27.12 MHz and 40.68 MHz) will be_x000D_
implemented. A comparison of the power transfer over a capacitively coupled wireless link will be evaluated_x000D_
for a range of spatial variation from 10 to 40 cm. Conclusions will be made regarding the robustness of the_x000D_
class E circuit topology when subjected to spatial impedance changes as well as the impact of link frequency on_x000D_
spatial impedance sensitivity., program purpose french : Wireless power transfer systems are an emerging technology with the aim of completely eliminating cables for_x000D_
