WIRELESS POWER TRANSMISSION DEVICE, WIRELESS POWER RECEPTION DEVICE, WIRELESS POWER TRANSMISSION SYSTEM AND WIRELESS POWER TRANSMISSION METHOD

摘要

A wireless power transmission device, a wireless power reception device, a wireless power transmission system, and a wireless power transmission method are provided. The wireless power transmission device includes a source coil and a resonant coil inductively coupled to the source coil. The source coil transmits power to the outside in an electromagnetic induction method at a first point. The source coil transmits power to the resonant coil in the electromagnetic induction method, and the resonant coil transmits the power received in the electromagnetic induction method to the outside at a second point different from the first point.
