Abstract
Various examples are provided for power amplifiers for coil array systems, which include load-independent Class E power amplifiers. In one example, a wireless charging system includes a three-dimensional (3D) coil array; and control circuitry configured to adjust a magnetic field generated by the 3D coil array, the control circuitry comprising a switching structure coupled to transmitting (TX) coils of the 3D coil array via independent matching networks. The independent matching networks can be LCL-matching networks.
