WIRELESS POWER SUPPLY SYSTEM, POWER TRANSMISSION DEVICE AND POWER RECEIVING DEVICE
First Claim
1. A wireless power supply system that wirelessly supplies electric power through electromagnetic waves, the wireless power supply system comprising:
- a power transmitter that transmits an electromagnetic wave;
a plurality of power receivers that is disposed on a rotatable object rotatable around a rotation axis and that receives the electromagnetic wave, the plurality of power receivers being disposed such that at least one power receiver of the plurality of power receivers is located within a coverage area formed by the electromagnetic wave transmitted by the power transmitter; and
a driver controller that calculates transmitting direction information for determining a transmitting direction of the electromagnetic wave for the power receiver located within the coverage area, from driver control data to drive and control rotation of the rotatable object,wherein the power transmitter includes;
a transmitting direction information obtainer that obtains the transmitting direction information; and
a direction controllable transmitter that transmits the electromagnetic wave in a direction calculated based on the transmitting direction information.
