Abstract
In this study, a complete design of a resonant inductive Wireless Power Transfer (WPT) system for battery-less systems will be presented. The main components of the resonant inductive WPT system are H-bridge inverter, transmitter side coil & compensation capacitor, magnetic core & medium, receiver coil & compensation capacitor and diode rectifier & filter capacitor. In this work, closed loop control mechanism, RF wireless communication, power-up strategy for battery-less receiver side application, loss budget and detailed system description of a series resonant inductive wireless power transfer system will be shown. The design and the proposed methods will be verified with simulations and experimental results.
