(FR) SYSTÈME DE TRANSMISSION DE PUISSANCE

Abstract
(EN)
Power transmission is performed by utilising magnetic field resonance coupling and electric field resonance coupling between a transmitting coil (Lp) and a receiving coil (Ls) by respective resonance achieved by producing resonance of: a transmission device-side resonant circuit including a resonant capacitor (Cr) connected in series with a transmission coil (Lp); and a receiving device-side resonant circuit including a resonant capacitor (Crs) connected in series with a receiving coil (Ls). By utilising the resonance effect, active power only is transmitted from the transmission device side to the receiving device side. Reflected reactive power is saved as resonance energy in the respective resonant circuits on the transmission device side and receiving device side.
(FR)
La transmission de puissance est réalisée en utilisant un couplage par résonance de champ magnétique et un couplage par résonance de champ électrique entre une bobine de transmission (Lp) et une bobine de réception (Ls) par résonance respective obtenue par production de résonance de : un circuit résonant côté dispositif de transmission comprenant un condensateur résonant (Cr) monté en série avec une bobine de transmission (Lp) ; et un circuit résonant côté dispositif de réception comprenant un condensateur résonant (Crs) monté en série avec une bobine de réception (Ls). En utilisant l'effet de résonance, la puissance active seulement est transmise du côté du dispositif de transmission au côté du dispositif de réception. La puissance réactive réfléchie est sauvegardée en tant qu'énergie de résonance dans les circuits de résonance respectifs sur le côté du dispositif de transmission et le côté du dispositif de réception.
(JA)
 送電コイル(Lp)に直列に接続された共振キャパシタ(Cr)を含む送電装置側共振回路と、受電コイル(Ls)に直列に接続された共振キャパシタ(Crs)を含む受電装置側共振回路とを共鳴させることによりそれぞれが共振し、そのことにより送電コイル(Lp)と受電コイル(Ls)との間で磁界共鳴結合と電界共鳴結合を利用して電力伝送を行う。共振現象を利用することで有効電力のみを送電装置側から受電装置側へ伝送し、反射した無効電力は送電装置側と受電装置側のそれぞれの共振回路において共振エネルギーとして保存される。
