Abstract
A charging pad includes a power drive unit and a transmitting unit. The power drive unit includes a first oscillator to generate a first AC voltage signal having a first frequency, and a first amplifier to amplify the first AC voltage signal. Also, the power drive unit includes a second oscillator to generate a second AC voltage signal having a second frequency, and a second amplifier to amplify the second AC voltage signal. Additionally, the power drive unit includes an adder to combine the amplified first AC voltage signal and the amplified second AC voltage signal. Furthermore, the transmitting unit includes a first frequency coil configured to transmit the amplified first AC voltage signal having the first frequency, and a second frequency coil configured to transmit the amplified second AC voltage signal having the second frequency.
