Abstract
A transmitting device includes a transmission power supply to output electric power, whose frequency matches a resonance frequency of each of the transmitting antennas, based on input power, plural switches respectively provided for the transmitting antennas, the switches being switchable to connect or disconnect supply lines for supplying the electric power outputted by the transmission power supply to the transmitting antennas, a parameter detector to detect parameters regarding the transmission power supply, the parameter being changed as a receiving antenna gets close to the transmitting antennas, by using a protective function of the transmission power supply, and a switch controller to estimate the position of the receiving antenna from the result of the detection, and to perform switching control on the switches in accordance with the position of the receiving antenna.
