<P>PROBLEM TO BE SOLVED: To provide a non-contact power transmission system without need of a wireless communication device transmitting load information from a power receiving machine side to a power transmitting machine side during impedance adjustment. <P>SOLUTION: A non-contact power transmission system comprises: a power transmission resonator 240; a power reception resonator 310; a matching circuit 220 for making input impedance of the power transmission resonator 240 and output impedance of a power supply 210 matched; a detection section 230 for detecting an AC signal input to the power transmission resonator 240; and an impedance control section 250 that controls the matching circuit 220 so as to match the input impedance of the power transmission resonator 240 and the output impedance of the power supply 210 based on a fluctuation in the AC signal detected by the detection section 230. <P>COPYRIGHT: (C)2012,JPO&INPIT |
