I. Introduction
Wireless power transfer (WPT) technology utilizes magnetic field, electric field, laser, microwave, or other medium to deliver electric power from the power source to electrical equipment without direct electrical contacts. With the increasing demand for wireless power supplies, it has attracted broad attention from researchers around the world [1], [2], [3]. The magnetic coupled WPT (MC-WPT) technology is a transmission method frequently used in charging electric vehicles (EVs) [4], especially for EV dynamic WPT (EV-DWPT). This technology not only extends the EV driving range but also makes a considerable reduction in battery size and capacity [5]. If 20% of the roads possess a 40-kW dynamic charging system, the driving range of an EV can be extended by at least 80% [6]. Also, the battery capacity of EVs with wireless charging could be reduced to 20% or less compared to EVs with conductive charging [7].
