Abstract:
A power transmission apparatus includes an inverter circuit, a power transmission antenna that wirelessly transmits alternating current power output from the inverter circuit, and a power transmission control circuit that causes the inverter circuit to output the alternating current power. The power transmission control circuit causes the inverter circuit to output the alternating current power as binary communication data by varying frequency of the alternating current power output from the inverter circuit between a first frequency and a second frequency, and performs amplitude control for eliminating a difference between amplitude of voltage of the alternating current power at a time when the frequency is the first frequency and amplitude of the voltage of the alternating current power at a time when the frequency is the second frequency.

Claim (Index 10):
A power reception apparatus for a wireless power transmission system including the power transmission apparatus and a power reception apparatus, the power transmission apparatus comprising:\n an inverter circuit that converts first direct current power supplied from a power supply into alternating current power and outputs the alternating current power; a power transmission antenna that wirelessly transmits the alternating current power output from the inverter circuit; and a power transmission control circuit that causes the inverter circuit to output the alternating current power and outputs the alternating current power as binary communication data by varying frequency of the alternating current power output from the inverter circuit between a first frequency and a second frequency, wherein the power reception apparatus includes a power reception antenna that receives the alternating current power wirelessly transmitted from the power transmission antenna, and a power reception amplitude modulator that varies amplitude of voltage of the alternating current power input to the power transmission antenna between a first amplitude and a second amplitude, wherein, when transmitting first binary communication data from the power transmission antenna to the power reception antenna through electromagnetic coupling between the power transmission antenna and the power reception antenna, the power transmission control circuit selects the first frequency as one of the first binary communication data and the second frequency as another of the first binary communication data, wherein, when transmitting second binary communication data from the power reception antenna to the power transmission antenna through the electromagnetic coupling, the power reception amplitude modulator selects the first amplitude as one of the second binary communication data and the second amplitude as another of the second binary communication data, and wherein the power transmission control circuit performs, using the inverter circuit, amplitude control for eliminating a difference between a third amplitude of the voltage of the alternating current power at a time when the frequency of the alternating current power is the first frequency and a fourth amplitude of the voltage of the alternating current power at a time when the frequency of the alternating current power is the second frequency.
