“…Thus, the total value of the impedance rate would progressively grow along with the misalignment under the topologies of parallel-series type, as well as the parallel-parallel type compensations, resulting in a sudden reduction in the value of the current [311]. PS-type and PP-type coils' compensations would offer a maximum power factor value (PF) value and very high efficacy at low mutual inductances, and thus, the broader value spectrum of mutual inductance variations and load fluctuation [312]. Table 10 shows the detailed symbol representation of the topologies.…”

Electric vehicles could be a significant aid in lowering greenhouse gas emissions. Even though extensive study has been done on the features and traits of electric vehicles and the nature of their charging infrastructure, network modeling for electric vehicle manufacturing has been limited and unchanging. The necessity of wireless electric vehicle charging, based on magnetic resonance coupling, drove the primary aims for this review work. Herein, we examined the basic theoretical framework for wireless power transmission systems for EV charging and performed a software-in-the-loop analysis, in addition to carrying out a performance analysis of an EV charging system based on magnetic resonance. This study also covered power pad designs and created workable remedies for the following issues: (i) how power pad positioning affected the function of wireless charging systems and (ii) how to develop strategies to keep power efficiency at its highest level. Moreover, safety features of wireless charging systems, owing to interruption from foreign objects and/or living objects, were analyzed, and solutions were proposed to ensure such systems would operate as safely and optimally as possible.

“…On the primary side, research on converters is mainly focused on the inverter as it is the driver for the circuit's operation. When designing inverters for WPT systems, the focus is heavily centered on achieving resonance [32][33][34][35][36]. Resonance allows for zero phase angle (ZPA) operation, which drastically increases power transfer efficiency as the reflected reactance of the secondary on the primary is purely resistive, so real power matches apparent power transferred.…”

This article classifies, describes, and critically compares different compensation schemes, converter topologies, control methods, and coil structures of wireless power transfer systems for electric vehicle battery charging, focusing on inductive power transfer. It outlines a path from the conception of the technology to the modern and cutting edge of the technology. First, the base principles of inductive coupling power transfer are supplied to give an appreciation for the operation and design of the systems. Then, compensation topologies and soft-switching techniques are introduced. Reimagined converter layouts that deviate from the typical power electronics topologies are introduced. Control methods are detailed alongside topologies, and the generalities of control are also included. The paper then addresses other essential aspects of wireless power transfer systems such as coil design, infrastructure, cost, and safety standards to give a broader context for the technology. Discussions and recommendations are also provided. This paper aims to explain the technology, its modern advancements, and its importance. With the need for electrification mounting and the automotive industry being at the forefront of concern, recent advances in wireless power transfer will inevitably play an essential role in the coming years to propel electric vehicles into the common mode of choice.
