“…The type of compensation network can be selected using the specific application requirements for the IPT system [17][18][19][20][21]. The series-series (SS) compensation topology is suitable for charging EV battery because the capacitance on the primary side is independent of the load and magnetic coupling coefficient [22,23]. the limitation of the planar coil includes high sensitivity to misalignment between two coils, which leads to inefficient power transfer [11][12][13].…”

This paper presents a novel inductive link for wireless power transfer (WPT) system of electric vehicles (EVs). The WPT technology uses an alternating magnetic field to transfer electric power through space. The use of the WPT technology for charging electric vehicle provides an excellent alternative to the existing plug-in charging technology. It has been reported that the inductive link using planar coils such as the circular and rectangular coil are capable of transferring a high power with high efficiency. However, they have a poor tolerance for lateral misalignment, thus their power transfer efficiency decreases significantly with the misalignment. Due to the poor misalignment performance of the planar coil topology, extensive studies have been carried out on the flux pipe topology due to their excellent misalignment tolerance. To address this, in this paper, a novel inductive link using double helix flux pipe topology is proposed. The performances of the inductive link using the proposed double helix flux pipe are analyzed and compared with inductive links using conventional flux pipe. The proposed model has excellent characteristics in terms of the power transfer efficiency and tolerance against misalignments. The proposed model is capable of transferring over 1.6 kW of power with a coil-to-coil efficiency of over 98.5% at a load resistance of 20 Ω.

“…Selection of the type of compensation network depends on the application demand in the wireless power transfer. Series-series compensated network is best for electric vehicle applications as it provides two important advantages: independency of value of the capacitor from the mutual inductance and load conditions, second is the ability of such systems to maintain a unity power factor by drawing active power at the resonant frequency [15,16]. This type can provide a finer battery charging alternative as it may provide a constant current and voltage for the battery [6,17].…”

Depletion in rising fuel prices and greenhouse gas emissions can be aided by electrified transportation. This evolution urges an installation of diversified charging networks, in an adaptable environment, to be successful. Wireless electric vehicle charging systems (WEVCS) can be a probable substitute technology to charge the EVs without any plug-in complications. In this paper, the present-day available wireless power transmit technology for electric vehicle is examined. And explanation of two prime applications of WEVCs and record of their progress with up-to-date features from universities, research laboratories are examined and presented. Moreover, the futuristic WEVCS; in-wheel and vehicle-to-grid WCS are compared with the existing ones.

“…This article focusses mainly on operational properties of the WPT system using the inductive-resonant coupling connected in four different configurations; series-series, series-parallel, parallel-series and parallel-parallel [5][6][7][8][9] The system evaluation is based on results from numerical simulation [13][14] and from experimental measurement [10][11][12] of 5 kW WPT system prototype. As some comparative parameters we introduce the power transferred to the load and the system operational efficiency including the input inverter, resonant tank and output rectifier.…”

-This article deals with mutual comparison of different resonant tank configurations of the wireless power transfer (WPT) systems. Tested compensation configurations are classified as series-series, series-parallel, parallel-series and parallel-parallel and all of them are operated with the input and output frequency converters and other supplementary electronics. As parameter we chose the transfer distance and load. The comparison is made according to changes in overall system efficiency and power delivered to the load along varying both the load and operational distance. All theoretical findings are experimentally verified and discussed in the conclusion section.
