Abstract
(EN) A power transmitter including first and second power transmission coils affecting each other has: a first power supply for driving the first power transmission coil; a second power supply for driving the second power transmission coil; and a power transmission control unit for, according to impedance information of the first and second power supplies, controlling at least one of the phase difference between and the intensity ratio between the output signal of the first power transmission coil and the output signal of the second power transmission coil. This makes it possible to transfer power under a desirable condition.
(FR) La présente invention concerne un émetteur de puissance, qui comprend des première et seconde bobines de transmission de puissance qui ont une influence les unes sur les autres. L'émetteur comprend : une première alimentation électrique, afin d'attaquer la première bobine de transmission de puissance ; une seconde alimentation électrique, afin d'attaquer la seconde bobine de transmission de puissance ; et une unité de commande de transmission de puissance afin de commander, en fonction des informations d'impédance des première et seconde alimentations électriques, au moins un élément parmi la différence de phase et le rapport d'intensité entre le signal de sortie de la première bobine de transmission de puissance et le signal de sortie de la seconde bobine de transmission de puissance. Cela permet de transférer de la puissance dans une condition souhaitable.
