Stabilizing the Operating Frequency of a Resonant Converter for Wireless Power Transfer to Implantable Biomedical Sensors

  title={Stabilizing the Operating Frequency of a Resonant Converter for Wireless Power Transfer to Implantable Biomedical Sensors},
  author={Ping Si and Aiguo Patrick Hu and David M. Budgett and Simon C. Malpas and Joseph Yang and Jinfeng Gao},
Resonant converters have been applied in wireless power supplies for implantable sensors due to their inherent advantages of low cost, high frequency and high reliability. However, the operating frequency of the resonant converter varies with the load and circuit parameters changes, which can significantly reduce the maximum power that the system can transfer. As a result the implanted sensors may not work properly because of insufficient power delivery. Uncertainty in frequency associated with…
