Etude, conception et réalisation d’un chargeur sans fil résonant par triangulation magnétique.

Abstract

This project is about study, design and production of a resonant wireless charger by magnetic triangulation. The objective is to propose a simplified sizing method making it possible to produce a wireless charger with an optimal coupling which, due to the magnetic triangulation, makes it possible to locate the receiver circuit regardless of its position in space. To achieve this, we made a study of the physical principle which is the basis of WPT, then we carried out simulations on the LTspice software. Also, we used integrated circuits for the realization of our device as well as the Lagrange mechanics to bring out the motion equation of our system. The results obtained during the simulation of our device are satisfactory. For 180W as a power in, we obtained as power out 12.5W whether, essential to reload the batteries of cellphone.
