Title (EN) ENERGY TRANSMISSION APPARATUS AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE TRANSMISSION D'ÉNERGIE
Abstract:
(EN) An apparatus and method for wirelessly transmitting electromagnetic energy are provided. The apparatus includes a power source, a transmission unit, and a measurement unit. The power source supplies a power according to a certain frequency. The transmission unit receives the power to wirelessly transmit the received power through self resonance. The measurement unit measures a phase difference between a voltage and current of the transmission unit. The certain frequency is controlled according to the phase difference. Accordingly, the apparatus and method control only the frequency of the power supply when a resonance frequency is changed by the change of an ambient environment, thus enhancing energy transmission efficiency.
(FR) La présente invention concerne un appareil et un procédé de transmission sans fil d'une énergie électromagnétique. L'appareil comprend une source de courant, une unité de transmission, et une unité de mesure. La source de courant fournit un courant en fonction d'une certaine fréquence. L'unité de transmission reçoit le courant pour transmettre sans fil le courant reçu par auto-résonance. L'unité de mesure permet de mesurer un déphasage entre une tension et un courant de l'unité de transmission. La fréquence est commandée en fonction du déphasage. En conséquence, l'appareil et le procédé ne commandent que la fréquence de l'apport du courant lorsqu'une fréquence de résonance est modifiée par la modification d'un environnement ambiant, ce qui permet d'améliorer l'efficacité de la transmission d'énergie.
