Abstract: A system for power transfer is provided. In one exemplary embodiment, the system includes an inductive power device, such as a device that transmits or receives power over an inductive coupling. For example, an adjustable impedance is coupled to the inductive power device, where the adjustable impedance is used for dynamically controlling the power gain in the inductive power device, such as by damping power generated by circuit impedances, such as inductances, capacitances or resistances, and combinations thereof.

Abstract: Coupled coil systems and methods are disclosed in which transmitter and receiver inductors, or coils, are coupled in a configuration for wirelessly transferring power among them.
