Abstract
Official abstract text for this publication.
Systems and designs for tuning a wireless power transfer system are provided, which may include any number of features. In one embodiment, a wireless power transfer system can be configured such that resonant frequencies of the system move towards an operating frequency of the system as a coupling coefficient between the transmit and receive resonators becomes smaller. In another embodiment, a receive controller can be configured to control a current delivered to a DC load by comparing an actual current at the DC load to a current requested by the DC load and adjusting an angle or a magnitude of a voltage at the DC load to match the requested current. In another embodiment, a rectifier circuit can act as a controlled voltage source and be configured to tune resonant frequencies between the transmit resonator and the receive resonator. Methods of use are also provided.
First claim
Opening claim text (preview).
What is claimed is: 1 . A wireless power transfer system comprising: a transmitter comprising a transmit resonator coupled to a voltage source; and a receiver comprising a receive resonator coupled to a load through a rectifier circuit, wherein the system is configured to be actively tuned by modifying a reactance of the load to tune a resonant frequency of the transmit and receive resonators. 2 . The wireless power transfer system of claim 1 , wherein…
