“…We have shown that this optimal impedance is dependent on the coupling factor k. If k is constant, the optimal impedance obviously does not change. However, for certain applications such as moving electric vehicles [26], automated guided vehicles [27] and a computer mouse [28], this coupling factor is variable in time. In that case, one has to allow that an ideal compensation network is not present all of the time, leading to non optimal transfer efficiencies.…”

Wireless power transfer using a magnetic field through inductive coupling is steadily entering the market in a broad range of applications. However, for certain applications, capacitive wireless power transfer using electric coupling might be preferable. In order to obtain a maximum power transfer efficiency, an optimal compensation network must be designed at the input and output ports of the capacitive wireless link. In this work, the conjugate image theory is applied to determine this optimal network as a function of the characteristics of the capacitive wireless link, as well for the series as for the parallel topology. The results are compared with the inductive power transfer system. Introduction of a new concept, the coupling function, enables the description of the compensation network of both an inductive and a capacitive system in two elegant equations, valid for the series and the parallel topology. This approach allows better understanding of the fundamentals of the wireless power transfer link, necessary for the design of an efficient system.

“…It can be seen that the CSIs require more components than the VSIs. For VSI topologies, buck, half-bridge, and full-bridge topologies shown in Figure 3d-f can be used in the IPT systems, and they are compatible with single capacitor series, LCL, and LCCL compensation networks [1,21,[56][57][58][59][60][61][62][63][64][65][66]. The series compensation is simple and cost-effective.…”

The acquisition of inductive power transfer (IPT) technology in commercial electric vehicles (EVs) alleviates the inherent burdens of high cost, limited driving range, and long charging time. In EV wireless charging systems using IPT, power electronic converters play a vital role to reduce the size and cost, as well as to maximize the efficiency of the overall system. Over the past years, significant research studies have been conducted by researchers to improve the performance of power conversion systems including the power converter topologies and control schemes. This paper aims to provide an overview of the existing state-of-the-art of power converter topologies for IPT systems in EV charging applications. In this paper, the widely adopted power conversion topologies for IPT systems are selected and their performance is compared in terms of input power factor, input current distortion, current stress, voltage stress, power losses on the converter, and cost. The single-stage matrix converter based IPT systems advantageously adopt the sinusoidal ripple current (SRC) charging technique to remove the intermediate DC-link capacitors, which improves system efficiency, power density and reduces cost. Finally, technical considerations and future opportunities of power converters in EV wireless charging applications are discussed.

“…While Equation (13) applies to inductors in free space, the coils of an IPT system for EV applications are usually embedded in complex environments where conductive and ferromagnetic materials are present. The magnetic field distribution is influenced by the presence of the vehicle chassis that usually exhibits a predominant conductive behaviour [30,31]. Moreover, aluminium shields are often used to confine the magnetic field for electromagnetic compatibility reasons while magnetic materials can be used to guide the magnetic flux, increasing the coupling and improving the tolerance to transmitter-receiver misalignments [13,14,32].…”

Abstract:The paper proposes the development of a set of rules for the resizing of inductive power transfer systems with particular attention to the ones dedicated to the charge of electric vehicles. These rules aim at the construction of down-scaled prototypes allowing the study and the design with benefits in terms of costs, time consumption and flexibility. The theoretical results are experimentally validated by comparing a 1.1 kW system with its down-scaled version.
