Multiplex wireless power transmission system and transmitting-side multiplex wireless power transmission apparatus
First Claim
1. A multiplex wireless power transmission system comprising:
- a primary transmission power supply that provides single frequency power;
a transmitter-receiver including plural channels of transmitting antennas that wirelessly transmit power provided from the primary transmission power supply and plural channels of receiving antennas that receive the power transferred from the paired transmitting antennas;
plural channels of transmission power circuits that establish resonance conditions of the paired transmitting antennas; and
plural channels of receiving power circuits that establish resonance conditions of the paired receiving antennas, whereinthe individual transmission power circuits provide the transmitting antennas 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.

Abstract
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.
