Advances in Wireless Power Transfer Technology
Wireless Power Transfer (WPT) systems, based on inductive power transfer (IPT) technology, are becoming increasing popular in many applications. As research in this area is progressing at a rapid rate, this seminar introduces some of the recent advances in IPT based WPT technology. New circuit and magnetic modelling techniques that can be employed to investigate different types of compensation circuits and coil structures are discussed. An optimal control strategy that allows for regulated power transfer with impedance matching for maximum efficiency, regardless of large variations in coupling and load, is also presented highlighting the key advantages.
