“…Furthermore, replacing the diodes at the secondary with power switches for bidirectional power flow results in increased power losses and introduces complexity to the control system [3]. A three-phase two-stage OBC rated at 10.5 kW with 95.6% efficiency and the power density of 1.75 kW/L is presented in [128]. This charger employs a diode bridge followed by a 90 kHz boost converter as the PFC stage, and an HB resonant LLC DC-DC converter operating within the switching frequency range of 90 kHz to 275 kHz at the HB battery side (see Figure 11a).…”

The rising Greenhouse Gas (GHG) emissions stemming from the extensive use of automobiles across the globe represent a critical environmental challenge, contributing significantly to phenomena such as global warming and the deterioration of air quality. To address these challenges, there is a critical need for research and development in electric vehicles (EVs) and their associated charging infrastructure, including off-board and on-board chargers (OBCs). This paper aims to bridge the gaps in existing review literature by offering a comprehensive review of both integrated and non-integrated OBCs for EVs, based on the authors’ knowledge at the time of writing. The paper begins by outlining trends in the EV market, including voltage levels, power ratings, and relevant standards. It then provides a detailed analysis of two-level and multi-level power converter topologies, covering AC-DC power factor correction (PFC) and isolated DC-DC topologies. Subsequently, it discusses single-stage and two-stage non-integrated OBC solutions. Additionally, various categories of integrated OBCs (iOBCs) are explored, accompanied by relevant examples. The paper also includes comparison tables containing technical specifications and key characteristics for reference and analysis.

“…These circuits are not much complex and can be studied using the conventional approaches based, as an example, on the Kirchhoff's laws [15]. Nevertheless, if the CNs are formed by two or more components and the coupled coils are more than two, the equations that describe the system functioning may result involved and it is difficult to recognize the effect of the single WPTS elements on the overall functioning [16], [17].…”

The wireless power transfer systems represent a viable solution to make more user friendly the procedure of charging the battery of electric vehicles. The performances of these systems are greatly affected by their compensation networks and are usually studied by considering their first harmonic equivalent circuits. This paper presents a new approach to writing the equations that describe these circuits and expresses them in a form that highlight the contribution of the coupled coils and of their compensation networks. The procedure to obtain the equations is described in details and the equations themselves are analyzed to derive from them the qualitative characteristics of the wireless power transfer system. In the last part of the paper a numerical analysis of a study case is reported, supporting the results by means of simulations.INDEX TERMS Compensation networks, Equivalent circuits, Wireless power transmission.

“…In Inductive Power Transfer (IPT) the coil structure is formed such that the two separated coupled coils or can be termed as a loosely coupled coils, they resonate at a frequency termed as resonant frequency hence this technology involves the resonant condition. The coils tend to operate at this resonance and, once tuned by either autotuning method or manual tuning method also to transfer power efficiently inspite of the air gap between the coils, efficiency, magnetic weak linkage and power transfer capability [5]- [9].…”

The transmission of electric power from a source point (front-end) to the load point (rear-end) destination offers to be a challenging one without any intermediate physical substance or either the annoying wires between them. As this originates from the experimentation of Testla in the year 1899 which is meant to be called as "World Wireless System", his experiment was done in the concept of microwave power generation which is most suitable for long distance and high frequency applications. Apart from the methods developed the promising wireless charging technology used is the ICPT by analyzing the design of charging coils, coupler, compensation network, power level enhancement and efficiency into major criteria. WPT is the technology that reduces the troubles in usages of wires and mainly long period charging of batteries. The objective of this paper aims in dynamically charging the online electric vehicle with the transmitter embedded inside the roads and the vehicle chassis as the receiver.
