One important technique of WPT technology is magnetic resonant coupling (MRC) WPT. Based on the advantages of MRC WPT, such as safety and high power transfer efficiency over a long transmit distance, there are many possible applications of MRC WPT. This paper provides a comprehensive, state-of-the-art review of the MRC WPT technology and wireless charging for electric vehicle (EV). A comparative overview of MRC WPT system design which includes a detailed description of the prototypes, schematics, compensation circuit topologies (impedance matching), and international charging standards. In addition, this paper provides an overview of wireless EV charging including the static wireless EV charging and the dynamic wireless EV charging, which focuses on the coil design, power transfer efficiency, and current research achievement in literature.

Application of Parity-Time Symmetry to Low-Frequency Wireless Power Transfer System

“…For magnetic induction wireless power transfer (WPT), such as the Qi standard, the transmitter and receiver coils, which contain a magnetic core, are usually driven at frequencies of a kilohertz to a few hundred kilohertz [1][2][3]. Capacitors are connected to coils [4] to compensate for leakage inductance [5]. Conventional equivalent circuits are used for analysis and design [6,7].…”

Coil Design for Wireless Vehicle-to-Vehicle Charging Systems

“…Magnetic resonant coupling WPT technology is well suited for use in wireless EV charging due to this technology's safety and high power transfer efficiency (PTE) over a long transmit distance [19]- [21]. Conventional wireless EV charging systems include a transmitter coil, which is embedded in the floor of the charging area, and a receiver coil, which is embedded in the vehicle's chassis.…”

Design and analysis of decoupled tetra‐polar ring‐coils for wireless power transfer in rotary mechanism applications

“…charging for underwater vehicles and solar wings [2, 3] etc. In recent years, it can be seen that there are increasing requirements for high‐power IPT system, and the power enhancement technologies of IPT systems become a significant research direction [6, 7]. However, due to the limitation of power‐level and cost of power electronic devices, it is difficult for a simple single‐input and single‐output IPT system to achieve high‐power wireless transmission.…”
