Abstract
A wireless power transfer (WPT) system is provided to drive multiple resonator coils utilizing one power amplifier. The WPT system may include a power amplifier, a differential 1:N power divider, impedance inversion circuits and multiple resonator coils. The WPT system may further include auto-tuning circuits with sensors that facilitate the efficient driving of the multiple resonator coils. As well, there is provided various 3D shaped coil topologies that are comprised of two or more separate coils. The 3D coil topology designs each provide a particular 3D magnetic field for wireless charging.
