Abstract
Disclosed herein is a wireless power transmission/reception apparatus. The wireless power transmission/reception apparatus includes a wireless power transmission unit and a wireless power reception unit. The wireless power transmission unit receives power, generates a wireless power signal to be wirelessly transmitted, wirelessly transmits the generated wireless power signal in a magnetic resonance manner, receives a returned wireless power signal and detects the number of power consumption devices, and wirelessly transmits a wireless power signal using resonance frequency appropriate for the number of power consumption devices.

17. A wireless power reception unit, comprising:
-
a second resonance antenna installed in a power consumption device, comprised of an inductor and a capacitor, and configured to receive a wireless power signal from a wireless power transmission unit using resonance frequency depending on the inductor and the capacitor in a magnetic resonance manner and return a remaining wireless power signal to the wireless power transmission unit; a power signal converter for converting the wireless power signal received through the second resonance antenna into a power signal appropriate for a power supply method and supplying the resulting power signal to the power consumption device; a power detector for detecting and outputting power intensity of the wireless power signal received through the second resonance antenna; and a controller for performing control so that the wireless power signal is received through the second resonance antenna and power is supplied to the power consumption device and so that the remaining wireless power signal is returned to the wireless power transmission unit. - View Dependent Claims (18, 19, 20, 21)
