<p><P>PROBLEM TO BE SOLVED: To provide a wireless charging system capable of preventing amplification of AC power due to reflection, when the battery of an electric vehicle is to be charged with power outputted from a power feeder. <P>SOLUTION: The power feeder 11 has a reflected power detecting section 25 for detecting AC power transmitted from a first resonance coil 24 and reflected on a second resonance coil 31. When the reflected power detected by the reflected power detecting section 25 exceeds a predetermined level, the power feeder stops the output of AC power from a carrier oscillator 21. Hence, the AC power can be prevented from abnormally increasing due to the superposition of the reflected power on transmission power. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
