SYSTEM FOR MOBILE UNIT MULTIPLEXED TRANSMISSION RESULTING FROM WIRELESS POWER TRANSMISSION

摘要

The present invention is provided with: a pair of transmission power sources (1) that supply electrical power; a transmission/reception unit (3) comprising a plurality of systems of transmission antennas (5) that wirelessly transmit supplied electrical power, and a plurality of systems of reception antennas (6) that each receive electrical power from the corresponding transmission antenna (5); a plurality of systems of transmission power source circuits (2) that each establish the resonance conditions of the corresponding transmission antenna (6); and a plurality of systems of reception power source circuits (4) that each establish the resonance conditions of the corresponding reception antenna (6). The transmission antennas (5) are provided with: a transmission-side coil (8) that is disposed with the axial core of a rotation body as the approximate center or around the axial core; and a transmission-side spacer (7) having a predetermined magnetic permeability and disposed in a manner so as to control the magnetic flux resulting from the transmission-side coil (8) for each system. The reception antennas (6) are provided with: a reception-side coil (10) that is disposed in the same manner as the transmission-side coil (8); and a reception-side spacer (9) having a predetermined magnetic permeability and disposed in a manner so as to control the magnetic flux resulting from the reception-side coil (10) in each system.
