Abstract
A non-contact power transmission apparatus that includes a power supply circuit that generates electrical power; a switch connected to an output of the power supply circuit; a first power transmission antenna connected to a first output of the switch; a second power transmission antenna connected to a second output of the switch; a communication interface that communicates with a device; and a control unit that controls the switch based on a state of the device obtained via the communication interface.
Claims20
A non-contact power transmission apparatus, comprising:
- a power supply circuit that generates electrical power;
- a switch connected to an output of the power supply circuit;
- a first power transmission antenna connected to a first output of the switch;
- a second power transmission antenna connected to a second output of the switch;
- a communication interface that communicates with a device;
- and
- a control unit that controls the switch based on a state of the device obtained via the communication interface.
A method performed by a non-contact power transmission apparatus, the method comprising:
- generating, by a power supply circuit, electrical power to be provided to one of a first power transmission antenna and a second power transmission antenna, which are each connected to an output of the power supply circuit via a switch;
- communicating, via a communication interface, with a device;
- and
- controlling, by a control unit, the switch based on a state of the device obtained from the device via the communicating.
A computer-readable medium including computer program instructions, which when executed by a non-contact power transmission apparatus, cause the non-contact power transmission apparatus to perform a method comprising:
- controlling a switch, which is connected between a power supply circuit that generates power and first and second power transmission antennas, based on a state of a device received via a communication interface of the non-contact power transmission apparatus.
