Title:
POWER TRANSMISSION MODULE, POWER TRANSMISSION DEVICE, AND WIRELESS POWER TRANSFER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/189374
Kind Code:
A1
Abstract:
This power transmission module is used for a power transmission device in a wireless power transfer system that can simultaneously transfer energy to two or more power reception electrode groups from a power transmission electrode group wirelessly via an electric field. The power transmission module is provided with: the power transmission electrode group that includes two or more power transmission electrodes; a first matching circuit connected between a first power conversion circuit that outputs a first AC voltage and the power transmission electrode group; and a second matching circuit connected between the power transmission electrode group and the first power conversion circuit or a second power conversion circuit that outputs a second AC voltage. The first and second matching circuits supply AC energies of the same phase to the power transmission electrode group.
