Abstract
A system includes at least one active energy transfer coil and a first passive energy transfer coil. The active energy transfer coil is configured to couple with a power supply. The at least one active energy transfer coil has an active coupling range. The first passive energy transfer coil is magnetically coupled to the active energy transfer coil and is located within the active coupling range. The first passive energy transfer coil has a passive coupling range. The first passive energy transfer coil is configured to provide energy to a first device located within the passive coupling range and based on energy received from the at least one active energy transfer coil.
Claims14
A system comprising:
- at least one active energy transfer coil configured to couple with a power supply, the at least one active energy transfer coil having an active coupling range;
- and
- a first passive energy transfer coil magnetically coupled to the at least one active energy transfer coil and located within the active coupling range, the first passive energy transfer coil having a passive coupling range, the first passive energy transfer coil configured to provide energy to a first device located within the passive coupling range and based on energy received from the at least one active energy transfer coil.
-14. (canceled)
A method comprising:
- selecting a range for wireless power transmission from a power supply to a load, the load having a receiver coil located within the range of at least one element of a plurality of elements of a power transmission network, each element having an energy transfer coil and at least one element coupled to the power supply;
- selecting a parameter for the power transmission network based on the range, the energy transfer coils and the receiver coil having a common resonance frequency;
- and
- configuring the power transmission network based on the parameter, the power transmission network configured to magnetically couple energy to the receiver coil.
