Abstract:
In a wireless charging system, a receiver device includes a second coil that performs a reactance shift. The reactance shift may be used to conform the device reactance to a reactance range, or to adjust a rectified voltage of the wireless power provided to the device electronics. The reactance shift differs from resonance matching in that the power transfer efficiency may be decreased.
