Abstract
A wireless power supply device that performs alternately a wireless communication operation and a wireless power supply operation. The wireless power supply device includes a transmission coil configured to generate an AC (alternating current) magnetic field, a communication driving circuit configured to supply a communication driving current to the transmission coil for generating the AC magnetic field during only the wireless communication operation, and not the wireless power supply operation, and a power supply driving circuit configured to supply a power supply driving current to the transmission coil for generating the AC magnetic field during both the wireless communication operation and the wireless power supply operation.
