Abstract

Disclosed is a mobile terminal. The mobile terminal includes a receiving unit to wirelessly receive power from a wireless power transmitter; and a sensing unit to sense a call signal, wherein, when the call signal is sensed, the mobile terminal transmits a transmission power control signal for controlling transmission power of the wireless power transmitter to the wireless power transmitter.

Description

technical field [0001] The present disclosure relates to a wireless power transmission technology. More particularly, the present disclosure relates to a mobile terminal capable of wirelessly receiving power using a wireless power transmission technology and a power control method thereof. Background technique [0002] Wireless power transmission or wireless energy transfer refers to a technique of wirelessly transferring power to a desired device. In the 19th century, a motor or a transformer employing the principle of electromagnetic induction has been widely used, and then a method for transmitting electric energy by radiating electromagnetic waves such as radio waves or laser has been proposed. Actually, an electric toothbrush or an electric razor frequently used in daily life is charged based on the principle of electromagnetic induction. Electromagnetic induction refers to a phenomenon in which voltage is induced so that current flows when a magnetic field around a c...
