An embodiment of the present invention provides a current collecting apparatus of a wireless power transmission system. The current collecting apparatus includes: a second coil that generates induced electromotive force by an electromagnetic field, which is generated from a power supplying device of a wireless power transmission system and vibrates at a predetermined frequency; a frequency matching part which is connected to both ends of the second coil and adjusts a resonant frequency of the second coil to be same with a predetermined frequency by compensating impedance; a rectifying circuit part which is connected to an output terminal of the frequency matching part and rectifies the induced electromotive force into direct currents; and a regulating circuit which collects switching signals based on voltages of the induced electromotive force, generates adjusted voltages by switching output voltages of the rectifying circuit part according to the switching signals, makes the adjusted voltages be smooth, and outputs the adjusted voltages. |
