In an electric power transmission device which transmits electric power between a primary coil and a secondary coil, a resonant frequency of the secondary coil side is arranged to become higher than a frequency of an oscillation signal of the primary coil side, so that a capacitance can be made small and the coupling coefficient of the primary coil and the secondary coil can be made high apparently and thus, efficiency of power transmission from the primary coil side to the secondary coil side can be improved.
L'invention concerne un procédé qui permet d'augmenter l'efficacité du transfert d'énergie entre le primaire et le secondaire d'un équipement conçu pour transférer l'énergie d'un primaire à un secondaire. On choisit pour le secondaire une fréquence de résonance dépassant une fréquence de signal d'oscillation du primaire, ce qui permet d'obtenir une capacité peu élevée pour un coefficient de couplage apparemment élevé entre le primaire et le secondaire. Ce procédé permet d'améliorer le transfert d'énergie entre le primaire et le secondaire.
