Abstract

L'invention concerne un dispositif de transmission de puissance qui comprend une source d'alimentation en courant alternatif (CA) pour délivrer en sortie une alimentation en courant alternatif ayant une fréquence prédéterminée, et une bobine primaire à laquelle l'alimentation en courant alternatif est fournie. La source d'alimentation en courant alternatif comprend une première unité de source d'énergie et une seconde unité de source d'énergie. Les première et seconde unités de source d'énergie sont chacune configurées de sorte à convertir l'énergie externe en une alimentation à courant alternatif pour délivrer en sortie l'alimentation en courant alternatif convertie lorsque l'alimentation externe est entrée. La valeur de tension nominale de la première unité de source d'énergie est supérieure à celle de la seconde unité de source d'énergie. La valeur de courant nominale de la seconde unité de source d'énergie est supérieure à celle de la première unité de source d'énergie. Soit la première, soit la seconde unité source d'énergie est choisie comme unité source d'énergie pour recevoir l'énergie externe et fournir l'alimentation en courant alternatif à la bobine primaire.
