<P>PROBLEM TO BE SOLVED: To solve the problem that it is difficult to concurrently execute power transmission and communication using a pair of coils. <P>SOLUTION: A power transmission part includes: a power transmission part modulator for modulating a first carrier wave by a first baseband signal; a power transmission coil; and a power transmission part amplifier for amplifying an output signal of the power transmission part modulator and generating a signal to be impressed to the power transmission coil. A power reception part includes: a power reception coil for receiving the signal by the first carrier wave modulated by the first baseband signal from the power transmission coil; a rectifier for rectifying the signal received by the power reception coil and taking out power; a power reception part demodulator for demodulating the signal received by the power reception coil and outputting the first baseband signal; and a directional brancher for distributing the signal received by the power reception coil to the rectifier and the power reception part demodulator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
