Abstract
L'invention concerne un système de transfert d'énergie sans fil (WPT), une unité de batterie pour un système de WPT, une unité de récepteur pour un système de WPT, et un procédé de transfert d'énergie sans fil (WPT). Le procédé comprend les étapes consistant à convertir une première tension continue émanant d'une batterie en une première tension alternative destinée à être transmise par l'intermédiaire d'une première bobine d'émetteur ; à coupler sans fil une première bobine de récepteur à la première bobine d'émetteur de sorte qu'une seconde tension alternative est induite dans la première bobine de récepteur ; à convertir la seconde tension alternative en une seconde tension continue pour alimenter une charge ; et à utiliser un système de commande de rétroaction sans fil pour accorder la fréquence de la première tension alternative en réponse aux variations d'une tension de sortie à travers la charge pour maintenir la tension de sortie dans une plage sélectionnée sous un courant variable tiré par la charge.
