Title:
AUXILIARY CIRCUITS FOR SELECTION AND ENHANCEMENT OF MULTI-FREQUENCY WIRELESS POWER TRANSFER TO MULTIPLE LOADS
Document Type and Number:
WIPO Patent Application WO2015120672
Kind Code:
A1
Abstract:
This invention is related to a novel method and apparatus that provides selective and enhanced power flow in wireless power transfer systems with multiple receivers. Auxiliary circuits are introduced in the receiver circuits (and relay circuits if applicable) so as to ensure proper frequency-selective wireless power flow to the appropriate targeted receivers, with the pickup power by the non-targeted receivers substantially reduced even if the chosen tuned frequencies for different receivers are not widely apart.
