Wireless-power-transfer-system (WPTS) based wireless electric vehicles (WEVs), classified into roadway powered electric vehicles (RPEVs) and stationary charging electric vehicles (SCEVs), are in the spotlight as future mainstream transportations. RPEVs are free from serious battery problems such as large, heavy, and expensive battery packs and long charging time because they get power directly from the road while moving. The power transfer capacity, efficiency, lateral tolerance, EMF, air-gap, size, weight, and cost of the WPTSs have been improved by virtues of innovative semiconductor switches, better coil designs, roadway construction techniques, and higher operating frequency. Recent advances in WPTSs for RPEVs are summarized in this review paper. The fifth-(5G) and sixth-generation (6G) on-line electric vehicles (OLEVs), which reduce infrastructure cost for commercialization, and the interoperability between RPEVs and SCEVs are addressed in detail in this paper. Major milestones of the developments of other RPEVs are also summarized. The rest of this paper deals with a few important technical issues such as coil structures, power supply schemes, and segmentation switching techniques of a lumped inductive power transfer system (IPTS) for RPEVs.

Inductively coupled power transfer (ICPT) systems, which are superior to batteries due to their real-time power supplycapacity have been used in mooring buoys for the purpose of long-term measurements. A multiple-receiver ICPT system for mooring buoys, which contains a mooring cable for transmitting power, is proposed in this paper to obtain the corresponding profile parameters. Series compensation is applied to all three sections, including the transmitter, the mooring cable and multiple receivers. The voltage of an underwater system with arbitrary load can be stabilized. On that basis, high efficiency can be obtained. By adopting Wolfram Mathematica a detailed analysis of both double-receiver and multiple-receiver ICPT systems for mooring buoys is presented. Finally, a prototype ICPT system with three receivers mounted on a 30 m mooring cable was built to verify the theoretical analysis. Experimental results show that the power transfer efficiency exceeds 45%. Both theoretical analysis and experiments indicate that this system is appropriate for measuring ocean profile parameters.

“…However, SS topology has two drawbacks: low design freedom and high sensitivity to variation of the LCT coupling coefficient. In the SS system operation frequency, input voltage and resistive load are predetermined for single LCT condition, and according to previous research, the power transfer profile of the fully tuned SS topology is easily affected by the coupling factor …”

Summary In this paper, a design of the compensation network with a variable inductor is proposed, considering a wide variation of the coupling coefficient in the inductive power transfer (IPT). The characteristics of the proposed compensation network are analyzed with respect to the variable antenna coupling conditions. The realization of the zero voltage switching (ZVS) and the reactive power demand are discussed through the theoretical deduction and numerical simulation. Influence of the variable inductor on the compensation network characteristics is examined in detail, and the control algorithm for achieving the coupling independent constant output voltage is proposed. Detailed steps to design a prototype fulfilling all performance requirements are given. Verification of the proposed method was carried out on the experimental model. Recorded output voltage variation is within 5% over the wide coupling range, implying a quite well characteristic of the coupling independent voltage output. Experimental results match well with the calculations, validating the rightness of the proposed variable inductor tuning method.
