Abstract:
(EN) Disclosed is a power transmission apparatus. The power transmission apparatus may comprise: a signal generator for generating a signal of a first frequency band for wireless charging; a power generation circuit for generating a modulation signal for modulating the signal of the first frequency band generated by the signal generator and amplifying transmission power of the signal of the first frequency band on the basis of a voltage supplied from the outside of the power transmission apparatus; a power transmission circuit for transmitting the amplified transmission power to a power reception apparatus through a first antenna; a second antenna for receiving information on a state of charge from the power reception apparatus through a second frequency band; and a control circuit for controlling the duty and frequency of the modulation signal on the basis of the state of charge. In addition, various embodiments recognized through the specification are possible.
(FR) L’invention concerne un appareil de transmission de puissance. L'appareil de transmission de puissance peut comprendre : un générateur de signaux pour générer un signal d'une première bande de fréquences pour une charge sans fil ; un circuit de production d'énergie pour générer un signal de modulation en vue de moduler le signal de la première bande de fréquences généré par le générateur de signaux et d'amplifier la puissance de transmission du signal de la première bande de fréquences sur la base d'une tension fournie depuis l'extérieur de l'appareil de transmission de puissance ; un circuit de transmission de puissance pour transmettre la puissance de transmission amplifiée à un appareil de réception de puissance par l'intermédiaire d'une première antenne ; une seconde antenne pour recevoir des informations sur un état de charge provenant de l'appareil de réception de puissance par l'intermédiaire d'une seconde bande de fréquences ; et un circuit de commande pour commander le cycle de service et la fréquence du signal de modulation sur la base de l'état de charge. De plus, divers modes de réalisation définis dans la description sont possibles.
