MULTIPLEX WIRELESS POWER TRANSMISSION SYSTEM AND TRANSMITTING-SIDE MULTIPLEX WIRELESS POWER TRANSMISSION APPARATUS

摘要

A system includes a primary transmission power supply 1 that provides single frequency power; a transmitter-receiver having plural channels of transmitting antennas 5 that wirelessly transmit power provided from the primary transmission power supply 1 and plural channels of receiving antennas 6 that receive the power transferred from the paired transmitting antennas 5; plural channels of transmission power circuits 2 that establish resonance conditions of the paired transmitting antennas; and plural channels of receiving power circuits 4 that establish resonance conditions of the paired receiving antennas, in which the individual transmission power circuits 2 provide the transmitting antennas 5 of adjacent channels with powers with half-wave resonance waveforms that avoid a period during which the power waves overlap on each other by shifting a phase of voltage or current of the powers.
