Multiplexed wireless power transmission system for moving component

摘要

A system has primary transmission power supply 1 that supplies power; transmitter-receiver 3 including plural channels of transmitting antennas 5 that wirelessly transmit supplied power and plural channels of receiving antennas 6 that receive power from paired transmitting antennas 5; plural channels of transmission power circuits 2 that establish resonance conditions of paired transmitting antennas 5; and plural channels of receiving power circuits 4 that establish resonance conditions of paired receiving antennas 6. Transmitting antennas 5 have transmitting-side coils 8 approximately centered around the axis of a rotating body or arranged around the axis; and transmitting-side spacers 7 with prescribed permeabilities arranged to control magnetic flux caused by transmitting-side coils 8 for individual channels. Receiving antennas 6 have receiving-side coils 10 placed in the same manner as transmitting-side coils 8; and receiving-side spacers 9 with prescribed permeabilities arranged to control magnetic flux caused by receiving-side coils 10 for individual channels.

1. A multiplexed wireless power transmission system for moving component via a rotating body, the multiplexed wireless power transmission system for moving component comprising:
a primary transmission power supply that supplies power; a transmitter-receiver having plural channels of transmitting antennas that wirelessly transmit the power fed from the primary transmission power supply and plural channels of receiving antennas that receive the power transferred from the transmitting antennas; plural channels of transmission power circuits that establish resonance conditions of paired transmitting antennas; and plural channels of receiving power circuits that establish resonance conditions of paired receiving antennas, wherein the transmitting antennas comprise:
transmitting-side coils approximately centered around an axis of the rotating body or placed around the axis; andtransmitting-side spacers that have prescribed permeability each, and are approximately centered around the axis of the paired transmitting-side coils so as to control magnetic flux caused by the transmitting-side coils for the individual channels, and wherein the receiving antennas comprise:
receiving-side coils approximately centered around the axis of the rotating body or placed around the axis in the same manner as the arrangement of the transmitting-side coils; andreceiving-side spacers that have prescribed permeability each, and are approximately centered around the axis of the paired receiving-side coils so as to control magnetic flux caused by the receiving-side coils for the individual channels.
