Abstract

The present disclosure provides a coil device, a wireless power transmitter, and a wireless power receiver. The coil arrangement may be capable of varying the gap between turns of the coil so that multiple devices may be wirelessly charged simultaneously or a single device may be wirelessly charged using concentrated power. The coil device may include: a case having an accommodating space and a charging area changed according to a user's selection; and a coil part having a coil body formed of a predetermined length of a wound conductor in the accommodating space of the case. The gap between the turns of the wound conductor of the coil body changes as the charging area of ​​the case changes.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2013-0160325 filed with the Korean Intellectual Property Office on December 20, 2013, the disclosure of which is hereby incorporated by reference. technical field [0002] The present disclosure relates to a coil device for wireless power transmission and a wireless power transmitter and a wireless power receiver having the coil device. Background technique [0003] Electrical and electronic devices are devices that operate using electricity as their energy source. [0004] In order to operate an electrical or electronic device, unless the device has a self-generating capability, it is necessary to supply the device with electrical power (ie, an energy source necessary to operate the device) from the outside. [0005] Therefore, in order to receive power from the outside, an electric or electronic device must be equipped with a power transmission device to transfer power from an external power usa...
