Title:
WIRELESS POWER TRANSMISSION DEVICE, AND METHOD FOR OPERATING SAME
Document Type and Number:
WIPO Patent Application WO/2024/039045
Kind Code:
A1
Abstract:
According to embodiments, a wireless power transmission device may comprise: a communication module; a plurality of antennas; a plurality of phase shifters; a power source; a distributor; and at least one controller. The wireless power transmission device can transmit basic power of a basic phase through a reference antenna. The wireless power transmission device can transmit first power through a first group of antennas. The wireless power transmission device can receive first group phase information from a wireless power reception device through the communication module, the first group phase information being calculated by the wireless power reception device on the basis of the basic power transmitted through the reference antenna and the first power transmitted through the first group of antennas. The wireless power transmission device can update the phases of the first group of antennas to first final phases on the basis of the first group phase information. The wireless power transmission device can transmit power of the first final phases through the first group of antennas.
