Abstract

An electronic device is provided which includes a power input unit including a first power input unit and a second power input unit, a switching unit including a first switching circuit connected with the first power input unit and a second switching circuit connected with the second power input unit, and a controller configured to receive selection information for selecting a power source to supply power to a load unit included in the electronic device of a first power source and a second power source, wherein the first power source and the second power source are connected with the first power input unit and the second power input unit, respectively, and control the switching unit to connect the first power source to the load unit according to the selection information.

First claim

What is claimed is:

1 . An electronic device, comprising:
a power input unit including a first power input unit and a second power input unit; a switching unit including a first switching circuit connected with the first power input unit and a second switching circuit connected with the second power input unit; and a controller configured to:
receive selection information for selecting a power source to supply power to a load unit included in the electronic device of a first power source and a second power source, wherein the first power source and the second power source are connected with the first power input unit and the second power input unit, respectively, and
control the switching unit to connect the first power source to the load unit according to the selection information.

2 . The electronic device of claim 1 , wherein the controller is further configured to control the switching unit to change the first power source connected with the load unit to the second power source without cutting off first power output from the first power source supplied to the load unit.

3 . The electronic device of claim 2 , wherein the controller is further configured to control the switching unit so that second power output from the second power source is supplied without cutting off the first power source supplied to the load unit.

4 . The electronic device of claim 1 , further comprising a power control device, wherein the controller is further configured to provide the power control device with information about which one of the first power source and the second power source supplies power to the load unit.

5 . The electronic device of claim 4 , wherein the controller selects the power source to supply the power to the load unit from the first power source and the second power source based on the selection information received from the power control device.

6 . The electronic device of claim 1 , wherein when the selection information is information for selecting a power source input last from the first power source and the second power source, and the controller is further configured to control the switching unit so that the last input power source supplies the power to the load unit.

7 . The electronic device of claim 1 , wherein when the selection information is information for selecting a power source input first from the first power source and the second power source, and the controller is further configured to control the switching unit so that the first input power source supplies the power to the load unit.

8 . The electronic device of claim 1 , wherein when the selection information is information for selecting a power source from the first power source and the second power source, and the controller is further configured to control the switching unit so that the selected power source supplies the power to the load unit.

9 . The electronic device of claim 1 , further comprising a third power input unit and a third switching circuit connected with the third power input unit, wherein when a third power source is connected with the third power input unit, the controller is further configured to control the switching unit to connect one of the first power source, the second power source, and the third power source to the load unit according to the selection information.

10 . A method of operating an electronic device, the method comprising:
sensing a connection of a first power source and a second power source to a first power input unit and a second power input unit, respectively; receiving selection information for selecting a power source to supply power to a load unit included in the electronic device from the first power source and the second power source; and controlling a switching unit to connect the first power source to the load unit according to the selection information.

11 . The method of claim 10 , further comprising changing the first power source connected with the load unit to the second power source so that second power output from the second power source is supplied without cutting off first power output from the first power source supplied to the load unit.

12 . The method of claim 10 , further comprising providing a power control device with information about which one of the first power source and the second power source supplies power to the load unit.

13 . The method of claim 10 , wherein selecting the first power source includes, when the selection information is information for selecting a power source input last from the first power source and the second power source, and controlling the switching unit so that the last input power source supplies the power to the load unit.

14 . The method of claim 10 , wherein selecting the first power source includes, when the selection information is information for selecting a power source input first from the first power source and the second power source, and controlling the switching unit so that the first input power source supplies the power to the load unit.

15 . The method of claim 10 , wherein selecting the first power source includes, when the selection information is information for selecting the first power source from the first power source and the second power source, controlling the switching unit so that the first power source supplies the power to the load unit.

16 . An electronic device, comprising:
an output unit connected with an external device; a power unit including a first power source and a second power source; a switching unit including a first switching circuit connected with the first power input unit and a second switching circuit connected with the second power input unit; and a controller configured to receive selection information for selecting a power source to supply power to the external device from the first power source and the second power source, and control the switching unit to connect the first power source to the external device through the output unit according to the selection information.

17 . The electronic device of claim 16 , wherein the controller is further configured to control the switching unit to change the first power source connected with the external device to the second power source without cutting off first power output from the first power source supplied to the external device.

18 . The electronic device of claim 17 , wherein the controller controls the switching unit so that second power output from the second power source is supplied without cutting off the first power supplied to the external device.

19 . The electronic device of claim 16 , further comprising a power control device, wherein the controller is further configured to provide the power control device with information about which one of the first power source and the second power source supplies power to the external device.

20 . The electronic device of claim 19 , wherein the controller is further configured to select the power source to supply the power to the external device from the first power source and the second power source based on the selection information received from the power control device.
