Title:
TRANSMITTER FOR MAGNETIC RESONANCE WIRELESS POWER TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/023031
Kind Code:
A1
Abstract:
The present invention relates to a transmitter for a magnetic resonance wireless power transmission system that can improve the efficiency of wireless power transmission by introducing a transmission frequency stabilisation layer so as to confine a reference frequency of a wireless power transmission unit within a minimum range not by means of software but by means of hardware, even in an environment where there are metal materials. The transmitter for a magnetic resonance wireless power transmission system of the present invention is technically characterised by comprising: a power supply unit; a drive frequency signal generator for receiving a drive voltage from the power supply unit and for generating a drive frequency signal for a wireless power transmission unit; a switch unit for receiving the drive voltage from the power supply unit and for amplifying the drive frequency signal generated from the drive frequency signal generator; and a wireless power transmission unit for transmitting power to a wireless power reception unit using the drive frequency signal provided from the switch unit, wherein the wireless power transmission unit is composed of a transmission coil layer for transmitting power wirelessly, and a transmission frequency stabilisation layer arranged in a lower side of the transmission coil layer.
