Abstract

A wireless power receiver according to an exemplary embodiment in the present disclosure may include a coil receiving power transmitted wirelessly in an inductive-coupling scheme; an electrode receiving power transmitted wirelessly in a capacitive-coupling scheme; and a rectifying unit connected to the coil and the electrode and rectifying input power to output supply power.

Claims

1. A wireless power receiver comprising:

a coil receiving power transmitted wirelessly in an inductive-coupling scheme;

an electrode receiving power transmitted wirelessly in a capacitive-coupling scheme; and

a rectifying unit connected to the coil and the electrode and rectifying input power to output supply power.

2. The wireless power receiver of claim 1, further comprising a printed circuit board including a first region in which the coil and the electrode are disposed, and a second region in which the rectifying unit is disposed.

3. The wireless power receiver of claim 2, wherein the coil is disposed on a first surface of the printed circuit board, and

the electrode is disposed on a second surface of the printed circuit board, which is opposite to the first surface of the printed circuit board.

4. The wireless power receiver of claim 3, wherein the first surface of the printed circuit board is disposed to face a wireless power transmitter transmitting the power wirelessly.

5. An electronic device comprising:

a wireless power receiver including a coil receiving power transmitted wirelessly in an inductive-coupling scheme and an electrode receiving power transmitted wirelessly in a capacitive-coupling scheme and outputting supply power; and

a load to which the supply power is input.

6. The electronic device of claim 5, further comprising a rectifying unit connected to the coil and the electrode and rectifying input power to output the supply power.

7. The electronic device of claim 5, wherein the wireless power receiver further includes a printed circuit board including a first region in which the coil and the electrode are disposed, and a second region in which the rectifying unit is disposed.

8. The electronic device of claim 7, wherein the coil is disposed on a first surface of the printed circuit board, and

the electrode is disposed on a second surface of the printed circuit board, which is opposite to the first surface of the printed circuit board.

9. The electronic device of claim 8, wherein the first surface is disposed to face a wireless power transmitter transmitting the power wirelessly.

10. The electronic device of claim 5, wherein the load is a charger charged with the supply power to output the power charged therein.

11. The electronic device of claim 5, wherein the load includes an electronic chip performing a predetermined operation when the supply power is input thereto.
