Increasing the robustness of electrodynamic wireless power receivers with hybrid transduction

Augmentation de la robustesse des récepteurs de puissance sans fil électrodynamiques par transduction hybride

Résumé

Electrodynamic wireless power transmission (EWPT) is a technique for transmitting power based on an electromechanical system operating at very low frequency. The power receiver converts a time-varying magnetic field first into mechanical power through the motion of a permanent magnet, and then into electrical power through an electromechanical transducer. One issue of electrodynamic WPT receivers is that they can be overexcited and break when subjected to strong magnetic fields. In this paper, we show that the simultaneous use of piezoelectric (PE) and electrodynamic (ED) transducers in a hybrid receiver allows taking advantage of both transductions to recover high levels of energy while limiting wear at higher magnetic field amplitudes.
