PURPOSE: Wireless power transfer device and method thereof are provided to improve transfer efficiency by transferring energy through a transfer resonance unit. CONSTITUTION: A plurality of transfer resonance units form a transfer pad. The resonance unit generates a magnetic field by receiving power from a power supply unit. A signal generation unit(12) generates a measurement signal. A current measurement unit(13) measures current within a wireless power transfer device. A control unit(15) transfers energy through at least one transfer resonance unit.
