METHOD AND APPARATUS FOR ADJUSTABLE COUPLING FOR IMPROVED WIRELESS HIGH Q RESONANT POWER TRANSFER |
摘要 |
Methods and apparatuses for wireless inductive power transfer are described herein. One implementation may include an apparatus for wireless inductive power transfer. The apparatus comprises a primary resonator configured to wirelessly transfer power to a secondary resonator coupled to a load of a wireless power receiver. The apparatus comprises a coupling circuit configured to couple energy from a source power supply to the primary resonator. The apparatus comprises a controller configured to coordinate an adjustment of a first amount of coupling between the source power supply and the primary resonator, via the coupling circuit, with an adjustment of a second amount of coupling between the secondary resonator and the load of the wireless power receiver. The coupling circuit comprises a first coupling loop comprising a plurality of segments, each configured to be selectively electrically connected to the source power supply, the first coupling loop electrically isolated from the primary resonator. |
