“…From Figure 5, it can be seen that both in the S-S and LCCL-S compensation topologies, the ZPA frequency bifurcation occurs in the case of small loads (R L = 1 Ω), and except for f o , two additional ZPA frequencies f L and f H are generated on both sides of f o . Bifurcation often occurs in the condition of high coupling coefficient or small load [24]. In the S-S compensation topology, when the system operation frequency f < f L_SS or f > f H_SS , although the load R L varies significantly, the voltage gain G v_SS is almost a constant.…”

“…Although the system operates under the detuning situation based on the analysis in Section 2, the primary coil current of LCCL-S also remains the same (I p_LCCL = U s /jω o L in ). The primary coil current of S-S can be obtained by substituting (24) into (4):…”

“…Under the detuning condition, even if the frequencies, loads, and other parameters remain the same, the variations in Cs may cause the input impedance to be changed. In the S-S compensation topology, when the primary loop operates at the ZPA frequency and the secondary loop operates in the detuning state caused by Cs variations, according to the previously derived equations, and together with (24), the input impedance of the S-S compensation topology under the detuning condition can be derived as:…”

In inductive power transfer (IPT) systems, series–series (S-S) and double capacitances and inductances–series (LCCL-S) compensation topologies are widely utilized. In this study, the basic characteristics of S-S and LCCL-S are analyzed and compared in the tuning state. In addition, considering the universality of detuning, and because the two topologies have the same secondary structures, the voltage and current stress on components, input impedances, voltage gains, and output powers of S-S and LCCL-S are mainly analyzed and compared in the detuning state, which is caused by variations in the secondary compensation capacitance. To compare the efficiency of the two topologies and verify the comparative analysis, comparative experiments based on a 2.4-kW IPT experimental prototype are conducted. The comparative result shows that the S-S compensation topology is more sensitive to load variations and less sensitive to secondary compensation capacitance variations than LCCL-S. Both in the tuning and detuning states, the efficiency of the S-S topology is higher in high-power electric vehicle (EV) applications, and the efficiency of LCCL-S is higher in low-power.

Considering a prospect where a driverless electric vehicle (EV) requires an automatic charging system that does not need a person to do anything. In this case, there is a need for a fully automated, fast, safe, cost‐effective, and reliable charging infrastructure that can be used for EVs and other EVs. This infrastructure must also be profitable and allow for quick adoption in electric transportation systems. Wireless charging methods may allow you to understand these characteristics. Wireless power transfer (WPT) is a future technology that offers flexibility, convenience, safety, and the capacity to be automated. Due to its high efficiency and ease of maintenance, resonant inductive wireless charging should get more attention in WPT techniques than other WPT methods. This literature provides an overview of the status of Resonant Inductive Wireless Power Transfer Charging technology, as well as a look at the current and prospects of the wireless EV industry. First, the article provides a brief history of wireless charging technologies, outlining the benefits and drawbacks. Then, the research assists in a comparative analysis of various types of WPT methodologies, control strategies, and compensation networks that have been done so far. The static and dynamic charging procedures, as well as their features, are shown. To increase charging power, a novel approach to the usage of superconducting materials in coil designs is examined, and their potential influence on wireless charging is highlighted. The detailed role and importance of power electronics, as well as the many types of converters utilized in diverse applications, are highlighted. The batteries and their management systems, as well as numerous WPT difficulties, are also discussed. Different trades are investigated, including cyber security economic consequences, health and safety, foreign object identification, and the effect and influence on the distribution grid. This article also highlights the opportunities and challenges associated with wireless charging systems. We anticipate that our effort will contribute to the advancement of WPT system research and development.
