POWER SUPPLY SYSTEM CAPABLE OF PROVIDING THE MOVING ELECTRONIC EQUIPMENT WITH THE POWER BY WIRELESS

摘要

PURPOSE: A power supply system for wirelessly providing power to a mobile electronic device is provided to conveniently supply power using a wireless power transferring device and a wireless power receiving device. CONSTITUTION: A wireless power transferring device is installed in an internal ceiling(20) to wirelessly transfer power. A wireless power receiving device is installed in a robot cleaner(200) on the bottom(10) of a power supply system to receive power which is transferred from the wireless power transferring device. The wireless power transferring device includes a harmonic wave generating unit(110), a harmonic wave amplifying unit(120), and a wireless transferring unit(130). The harmonic wave generating unit outputs a harmonic wave to the harmonic wave amplifying unit. The harmonic wave amplifying unit amplifies a harmonic wave and outputs the amplified harmonic wave to the wireless transferring unit.
