RADIO POWER TRANSMITTING APPARATUS AND RADIO POWER TRANSMITTING SYSTEM
First Claim
1. A radio power transmitting apparatus comprising:
- a power transmitting coil configured to be supplied with a signal and transmit the signal to a power receiving coil on a radio power receiving apparatus through magnetic coupling;
a band signal generating unit configured to generate a band signal having an allowable transmission band and supply the band signal to the power transmitting coil as the signal;
a reflected signal measuring unit configured to measure a reflected signal of the band signal from the power transmitting coil;
an oscillator configured to generate a carrier signal having a controllable oscillating frequency; and
a communication control unit configured to determine a transmission frequency based on a frequency characteristic of the reflected signal and perform control so that a transmission signal generated by modulating the carrier signal of the transmission frequency is supplied to the power transmitting coil as the signal.

Abstract
There is provided a radio power transmitting apparatus including: a power transmitting coil, a band signal generating unit, a reflected signal measuring unit, an oscillator and a communication control unit. The coil is supplied with a signal and transmits the signal to a power receiving coil on a radio power receiving apparatus through magnetic coupling. The generating unit generates a band signal having an allowable transmission band and supplies the band signal to the power transmitting coil. The reflected signal measuring unit measures a reflected signal of the band signal from the power transmitting coil. The oscillator generates a carrier signal having a controllable oscillating frequency. The control unit determines a transmission frequency based on a frequency characteristic of the reflected signal and performs control so that a transmission signal generated by modulating the carrier signal of the transmission frequency is supplied to the power transmitting coil.
