An overview of power circuit topologies for inductive power transfer systems

Inductive Power Transfer (IPT) systems have been more and more popular as they offer numerous advantages over conventional wired power transfer systems in terms of convenience, safety, isolation, and flexibility. This paper presents an overview of power converter topologies as well as modulation strategies for IPT systems. Besides, a brief introduction to the overview of fundamental components in IPT systems will also be presented to give a better basic knowledge of IPT systems to the readers.
