Abstract: In electric power supply through wireless signals, electric power is supplied efficiently, even when distance fluctuation is caused between an electric power transmitting device and an electric power receiving device. Even when distance fluctuation is caused between the electric power transmitting device for supplying electric power with the use of wireless signals and the electric power receiving device for receiving electric power supplied from the electric power transmitting device, the Q value of the electric power transmitting device is adjusted to optimize the transmission efficiency. The impedance of a resonance circuit of the electric power transmitting device is fluctuated at a constant frequency, the resulting reflected wave is detected as a response signal by the electric power transmitting device, and the Q value of the electric power transmitting device is adjusted to optimize the transmission efficiency.

Abstract: Not a structure in which a resonance frequency of a power transmission device is set after a resonance frequency of a power receiving device is directly measured but a structure in which the resonance frequencies of the power receiving device and the power transmission device are estimated after reflection of an electromagnetic field for transmitting electric power to the power receiving device is monitored by the power transmission device is employed. After a capacitance value of a variable capacitor in a resonance coil of the power receiving device is once set to 0, an S11 parameter is detected while a frequency of an electromagnetic wave is changed, and the resonance frequency of the power transmission device is estimated on the basis of the S11 parameter.
