Abstract
A system includes a first device, a second device, and a power control block. The first device has a first power converter and a first resonator which has a first resonant capacitor and a first coil. The second device has a second power converter and a second resonator which has a second resonant capacitor and a second coil. The second power converter is coupled to a ratio-controllable power converter, and the first coil and the second coil are magnetically coupled. The power control block is configured to adjust the system frequency, the second power converter output voltage and the current in the first coil in coordination.
