Abstract

A wireless power transmission apparatus is provided. The wireless power transmission device includes a source unit comprising a source resonator to transmit power wirelessly to at least one target device, and an energy charging module to store energy generated by the source unit under a control of the source unit.

Claims

1. A wireless power transmission apparatus, comprising:

a source unit comprising a source resonator for transmitting power wirelessly to at least one target device; and

an energy charging module for storing energy generated by the source unit under a control of the source unit.

2. The wireless power transmission apparatus of claim 1, wherein the energy charging module charges power that is obtained by subtracting power consumed by the at least one target device from power input to the source unit.

3. The wireless power transmission apparatus of claim 1, wherein the energy charging module retransmits the stored energy to the source unit.

4. The wireless power transmission apparatus of claim 1, wherein the energy charging module provides the stored energy to a device connected to the energy charging module.

5. The wireless power transmission apparatus of claim 1, wherein the energy charging module comprises:

a charging resonator to receive power from the source resonator; and

a large capacity capacitor to store the power received by the charging resonator.

6. An energy charging module for storing energy from a source unit that wirelessly transmits power to one or more target devices, the energy charging module comprising:

a charging resonator to receive power from the source unit; and

a large capacity capacitor to store the power received by the charging resonator,

wherein the energy charging module is controlled by the source unit.

7. The energy charging module of claim 6, wherein the source unit controls the energy charging module to store power received by the source unit but not transmitted by the source unit to the one or more target devices.

8. The energy charging module of claim 6, wherein the charging resonator receives an amount of power from the source unit, and the amount of power is equal to the amount of power input to the source unit minus the amount of power consumed by the one or more target devices.

9. The energy charging module of claim 6, wherein the energy charging module reuses the energy received from the source unit by transmitting the energy back to the source unit.

10. The energy charging module of claim 6, wherein the energy charging module reuses the energy received from the source unit by transmitting the energy to the one or more target devices.

11. The energy charging module of claim 6, wherein the energy charging module is included in the source unit.

12. The energy charging module of claim 6, wherein the energy charging module is not included in the source unit, and the energy charging module receives power from the source unit through magnetic coupling.
