Abstract:
1. Wireless electric power feeding equipment for feeding electric power in a contactless manner to an electric power receiving device including an electric power receiving unit, comprising: an electric power supply device generating electric power having a prescribed frequency; an electric power transfer unit for receiving electric power from said electric power supply device and for transferring the electric power to said electric power receiving unit in a contactless manner by resonating with said electric power receiving unit via an electromagnetic field; a detection device for detecting power reflected to said electric power supply device; a discharging device configured of one of a discharging coil for externally discharging electric power output from said electric power supply device and a resistor for consuming electric power output from said electric power supply device; and a connection device electrically connecting said discharging device between said electric power supply device and said electric power transfer unit when the reflected power detected has a value exceeding a predetermined value.
