Multi-frequency power driver for wireless power transfer system

摘要

The wireless power transmission system includes a plurality of receivers 310, 320, 330 each including at least one load 311, 321, 331, a plurality of receivers operating at different resonance frequencies, and a difference between the plurality of receivers. A driver 300 for generating a power signal including a plurality of drive signals 411, 412, 413 having various frequencies substantially matching a resonant frequency to be coupled to the driver and wirelessly coupled to each of the plurality of receivers. A pair of transmitter electrodes 304, 305, wherein the power signal generated by the driver is fed from the pair of transmitter electrodes to the plurality of receivers to power the respective load of each of the plurality of receivers. And the load of each receiver of the plurality of receivers is such that the frequency of one of the plurality of drive signals is equal to the resonance frequency of the receiver. Powered when qualitatively match, and a pair transmitter electrodes.
