Abstract
A wireless power transmission system transmits power from a power transmitting apparatus to a relay power receiving apparatus by applying voltage to an active electrode in the power transmitting apparatus, which is opposed to an active electrode in the relay power receiving apparatus, and a passive electrode in the power transmitting apparatus, which is opposed to a passive electrode in the relay power receiving apparatus.
Claims20
An electronic apparatus for wirelessly receiving and transmitting power, the apparatus comprising:
- an input circuit configured to wirelessly receive power from an external power source;
- a supply circuit configured to rectify and smooth the power received by the input circuit and supply the power to a load;
- and
- an output circuit electrically coupled to the input circuit and configured to wirelessly transmit the power received by the input circuit to an external power receiving device.
A wireless power transmission system comprising:
- a power transmitting device including:
- an active electrode,
- a passive electrode, and
- a power source configured to apply an alternating-current voltage to the active and passive electrodes;
- a first power receiving device including:
- a first housing;
- a first active electrode disposed in the first housing to oppose the active electrode of the power transmitting device when the first power receiving device is placed the power transmitting device,
- a first passive electrode disposed in the first housing to oppose the passive electrode of the power transmitting device when the first power receiving device is placed on the power transmitting device,
- a second active electrode coupled to the first active electrode, and
- a second passive electrode coupled to the first passive electrode;
- and
- a second power receiving device including:
- a second housing
- a third active electrode disposed in the second housing to oppose the second active electrode of the first power receiving device when the second power receiving device is placed on the first power receiving device,
- a third passive electrode disposed in the second housing to oppose the second passive electrode of the first power receiving device when the second power receiving device is placed on the first power receiving device, and
- a load configured to receive a voltage induced at the third active and passive electrodes.
A method for wirelessly receiving and transmitting power by a power receiving device, the method comprising:
- wirelessly receiving power at an input circuit from an external power source;
- rectifying and smoothing the power received by the input circuit;
- supplying the rectified and smoothed power to a load;
- and
- wirelessly transmitting by an output circuit to an external power receiving device the power received by the input circuit.
