Embodiment Construction

[0022] Exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings.

[0023] figure 1 is a diagram schematically showing a state in which the contactless power receiving apparatus according to the exemplary embodiment of the present disclosure receives power from a charging pad.

[0024] refer to figure 1 , the contactless power receiving apparatus according to the exemplary embodiment of the present disclosure may receive power from the charging pad A in a contactless scheme.

[0025] Here, the non-contact scheme may refer to a scheme that transmits power without direct connection between conductors of the transmitter and the receiver in the process of transmitting power from the transmitter to the receiver, that is, a non-contact scheme, a wireless transmission scheme, or the like.

[0026] The non-contact power receiving apparatus B according to the exemplary embodiment of the present disclosure may be a wear...

A non-contact power receiving device may include: a first power receiving coil and a second power receiving coil; The power of one of the power receiving coils is rectified.

Description

[0001] This application claims priority to and the benefit of Korean Patent Application No. 10-2014-0108568 filed in the Korean Intellectual Property Office on August 20, 2014, the disclosure of which is incorporated herein by reference. technical field [0002] The present disclosure relates to a contactless power receiving apparatus capable of charging a battery using power supplied in a contactless scheme. Background technique [0003] Electronic devices operate using electricity as an energy source. [0004] In order to operate electronic equipment, it is necessary to supply electric power to the electronic equipment as an energy source. The electronic device can generate its own power, or it can receive power from an externally powered device. [0005] In order for an electronic device to receive power from an external power supply device, a power supply device for transmitting power from the external power supply device to the electronic device is required. [0006] ...
