Abstract

A wireless power transmission device is disclosed. The device comprises: a charging pad; and a control unit included in the charging pad and specifying a power transmission group including a pluralityof power transmission units for recognizing a wireless power reception device and at least one power transmission unit for transmitting power to the wireless power reception device, wherein the control unit can control a phase of the power transmission group for the wireless power reception device and adjust the power, to be transmitted to the wireless power reception device, of the power transmission group. Therefore, device efficiency can be improved.

Description

Technical field [0001] The embodiment relates to a wireless power transmission device and a control method thereof, and more particularly, to a wireless power transmission device having a plurality of charging transmission units and a control method thereof. Background technique [0002] Recently, with the rapid development of information and communication technology, a society based on the popularization of information and communication technology is taking shape. [0003] In order for information and communication equipment to be connected anytime and anywhere, sensors equipped with computer chips with communication functions should be installed in all facilities throughout the society. Therefore, power supply for these devices or sensors has become a new challenge. In addition, as the types of mobile devices (for example, Bluetooth mobile phones and iPods and mobile phones) rapidly increase in number, it takes time and effort for users to charge batteries. As a method to solve...
