Magnetic resonance wireless power transfer (WPT) is a very promising technology for a wide range of applications. The transmission range and efficiency of wireless power transfer have been reasonably enhanced by resonating transmitter and receiver coil at a common frequency. The transmitter and receiver sides have to be perfectly tuned, otherwise power transfer capability is greatly reduced. This paper discusses the detuning effect of parallel compensated receivers, and thereof a novel self-tuning method and related circuit topology and control is proposed and characterized in the system application. The proposed method is based on the concept of switch-mode gyrator emulating variable lossless inductors oriented to enable self-tunability in WPT receivers.
