Abstract
An inductive power supply including multiple tank circuits and a controller for selecting at least one of the tank circuits in order to wirelessly transfer power based on received power demand information. In addition, a magnet may be used to align multiple remote devices with the inductive power supply. In one embodiment, different communication systems are employed depending on which coil is being used to transfer wireless power.
Claims20
An inductive power supply for supplying wireless power to and receiving communication from a remote device, said inductive power supply comprising:
- a first primary capable of being energized to transfer power wirelessly to the remote device and capable of receiving communication from the remote device;
- a second primary capable of being energized to transfer power wirelessly to the remote device and capable of receiving communication from the remote device;
- a controller programmed to selectively transfer power wirelessly to the remote device by energizing at least one of said first primary and said second primary, said controller programmed to receive communication from the remote device via at least one of said first primary and said second primary.
An inductive power supply for supplying wireless power to and receiving communication from a remote device, said inductive power supply comprising:
- a first primary means capable of being energized to transfer power wirelessly to the remote device and capable of receiving communication from the remote device;
- a second primary means capable of being energized to transfer power wirelessly to the remote device and capable of receiving communication from the remote device;
- a control means programmed to selectively transfer power wirelessly to the remote device by energizing at least one of said first primary means and said second primary means, said control means programmed to receive communication from the remote device via at least one of said first primary means and said second primary means.
A method for supplying wireless power to and receiving communication from a remote device, said method comprising:
- providing a first primary capable of being energized to transfer power wirelessly to the remote device and capable of receiving communication from the remote device;
- providing a second primary capable of being energized to transfer power wirelessly to the remote device and capable of receiving communication from the remote device;
- selectively transferring power wirelessly to the remote device by energizing at least one of said first primary and said second primary;
- and
- receiving communication from the remote device via at least one of said first primary and said second primary.
