Abstract
At least one component for a wireless power transmitter or a wireless power receiver. The at least one component includes a mechanical structure and/or circuitry configured to maintain and/or adjust a coupling coefficient K between the wireless power transmitter and the wireless power receiver, a loaded quality factor Q of the wireless power receiver, or both, such that K times Q is less than a constant.
Claims23
At least one component for a wireless power transmitter or a wireless power receiver, the at least one component comprising:
- a mechanical structure and/or circuitry configured to maintain and/or adjust a coupling coefficient K between the wireless power transmitter and the wireless power receiver, a loaded quality factor Q of the wireless power receiver, or both, such that K times Q is less than a constant,
- wherein the constant is between 0.8 and 1.0, inclusive.
A method of controlling a wireless power transmitter or a wireless power receiver, the method comprising:
- adjusting a coupling coefficient K between the wireless power transmitter and the wireless power receiver, a loaded quality factor Q of the wireless power receiver, or both, such that K times Q is less than a constant,
- wherein the constant is between 0.8 and 1.0, inclusive.
A wireless power transfer system, comprising:
- a wireless power transmitter;
- and
- a wireless power receiver,
- wherein the wireless power transmitter, the wireless power receiver or both the wireless power transmitter and the wireless power receiver are configured to maintain a product of a coupling coefficient K between the wireless power transmitter and the wireless power receiver and a loaded quality factor Q of the wireless power receiver to be less than a constant,
- wherein the constant is between 0.8 and 1.0, inclusive.
