Abstract

L'invention concerne un transfert d'énergie inductif à travers un espace étendu (100) à partir d'un conducteur primaire (119), au moyen d'une boucle intermédiaire résonnante comprenant un condensateur (118) à bobine d'induction (117) - pouvant être simplement un fil non hélicoïdal - transportant un courant de résonance plus grand, qui peut à son tour générer un champ inductif devant être recueilli par une bobine d'appel (120). Cette boucle peut augmenter la vitesse de transfert ou réduire la précision d'alignement requises dans un système de transfert d'énergie inductif s'utilisant pour des véhicules ainsi que pour des dispositifs d'éclairage et d'affichage, et peut également présenter des caractéristiques de stabilisation de fréquence. Un panneau publicitaire électroluminescent peut être alimenté à partir d'un oscillateur sinusoïdal à 1,2 kHz; son alimentation c.c à 50 volts étant recueillie par une bobine d'appel secondaire commandée accordée à une fréquence du réseau de 15kHz et placée à côté d'une bobine d'appel intermédiaire; ce panneau est également résonnant à la fréquence du réseau et est commandé par couplage inductif à partir d'un conducteur primaire alimenté par un courant alternatif à la fréquence du réseau.
