WIRELESS POWER TRANSFER USING STACKED RESONATORS

摘要

A wireless power transfer system may include a primary resonator and one or more secondary resonators. At least one of the secondary resonators lie in overlapping relation to the primary resonator. An electromagnetic (EM) field generated by the primary resonator can couple to the secondary resonators, thus inducing current flow in the secondary resonators. EM fields generated by the secondary resonators interact with the EM field from the primary resonator to produce a resultant EM field.

1. An apparatus operative with a primary resonator substantially disposed on a first plane, said primary resonator coupled to a power source, said apparatus comprising:
at least one secondary resonator substantially disposed on a second plane and coextensive with at least a portion of said primary resonator, said at least one secondary resonator being galvanically isolated from said primary resonator, said at least one secondary resonator configured to generate a secondary magnetic field when coupled with a primary magnetic field generated by said primary resonator so that a resultant magnetic field arises from interactions between said primary and secondary magnetic fields.
