WIRELESS POWER TRANSMISSION DEVICE AND OPERATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/136454
Kind Code:
A1
Abstract:
A wireless power transmission device is disclosed. A wireless power transmission device according to various embodiments may comprise: a transmission coil including a first member, which has one end and the other end forming a first angle with a plane, and a second member, which is arranged on the plane and is connected to each of the one end and the other end of the first member; an impedance sensor for outputting a voltage value corresponding to an impedance change amount of a resonance circuit, which includes the transmission coil; a magnetic body having a side surface that is dented, the dented side surface facing a portion of the transmission coil; a motor for moving the magnetic body; and a processor, which receives the output voltage value from the impedance sensor, calculates the difference value between a reference voltage value and the received voltage value, determines control information about the motor on the basis of the calculated difference value, and drives the motor through the determined control information so as to control the distance between the magnetic body and the portion of the transmission coil.
