I. Introduction
An inductive power transfer (IPT) system transfers power from one circuit to another through electromagnetic induction without any physical contact. It has been used in various applications ranging from a few milliwatts in biomedical applications up to several kilowatts of output power in automotive applications [1]–[4]. Due to its convenience and safety against electric shock, IPT has become increasingly popular in home appliances, mobile devices, industrial sensors, and electric vehicle (EV) chargers [5]– [7].
