Long range wireless power transfer via magnetic resonance

Abstract

This work presents an end-to-end highly efficient solution for wireless charging electronic devices at a distance of 0.5 meters. It is achieved by Wireless Power Transfer (WPT) that aims to solve the problem where people would not be reliant on sitting near a power socket to charge their electronic devices. Instead, they would be able to charge them wirelessly. Moreover, the need of cost-effective end-to-end long-range WPT in a single package is emerging. Here, we propose design considerations for a cost-effective and power ã 70% efficient end-to-end system for a long-range WPT system via magnetic resonance (MR). The design with the optimal TE was opted and tested for different transmission distances, frequencies, and load types. We also discuss different factors affecting the TE and the power delivered to the load using simulation tools and back them with experimental results.
