DescriptionWireless power transfer (WPT) via inductive links has been an attractive solution for powering biomedical implants. Due to the nature of the human body (e.g. body movement or changes in the biological environment), however, the transmitter (TX) and receiver (RX) coils involved in WPT are prone to misalignment, causing variations in the coupling factor. The variation in the coupling factor results in variations in the voltage that is delivered to the load on the receiver end. A solution to the problem of load voltage variation is to employ negative feedback on the transmitter end. Towards this goal, a feedback control architecture is proposed for the regulation of the load voltage under coupling variations. It is shown that by controlling the power supply on the transmitter end, through voltage-mode feedback control, the load voltage can be regulated. In the design of the controller, the open-loop system of the power control unit and WPT system have been taken into consideration. Theoretical derivations are presented and the validity of the proposed concept is investigated using simulations.
