“…Moreover, safe operation of the inverter in case of misalignment, and improvement of light load efficiency can be achieved [104]. The LCC-based topologies such as LCC-S [105-108], the LCCC-S [109], the LCC-SP [110], the LCC-P [111,112], and the LCC-LCC [113][114][115][116][117] are widely used in the IPT application due to its suitable performance. Although the LCC-P topology has a constant output current behavior, Zero Phase Angle (ZPA) switching is not achievable [112].…”

Inductive power transfer (IPT) for Electric Vehicles (EVs) is an emerging technology that can transfer power wirelessly over certain distances, thus offering some remarkable characteristics in terms of flexibility, position and movability. The output power of an IPT system depends on the coupling factor of the magnetic couplers which can deviates from the nominal operating conditions due to occurrence of misalignment. Nevertheless, misalignment of the magnetic couplers in inductive charging is inevitable, and it usually results in the variation of the mutual inductance and output power of the system with corresponding decrease in the system overall efficiency. So far, the literature has reported various techniques for achieving designs with higher misalignment tolerance. The reported techniques can be mainly classified into three categories, as viewed from the following aspects: magnetic couplers layouts, compensation networks and control strategy. Each of these techniques has its pros and cons in terms of implementation cost, system layout, efficiency, power density and reliability depending on the application. With the increased investigation of more applications of IPT, new modified techniques of improving the misalignment tolerance in the IPT system are continuously being proposed based on permutations and combinations of the existing ones; thus causing some confusion and difficulties for researchers and system vendors to follow. This paper, therefore, aims to provide a comprehensive review of the existing methods for IPT systems that address the misalignment issue in EVs wireless charging. A review of the IPT system is presented and an investigation of the numerous factors affecting the output power and performances of the system when the coils are not aligned. In addition, the advantages and disadvantages of each technique on the IPT system's performance are analyzed in detail.

“…The first step is to estimate the cross-coupling between adjacent main WPT coils through measurements or simulations. Next, by changing the number of turns n and surface area A = l × h of the auxiliary coils, the sum of M ATx and M AA can be adjusted to compensate the existing cross-coupling according to (5). Limited by the increase in coil series resistance and ferrite core saturation, the number of turns and surface area of the auxiliary coils are adjusted between n = 1 ∼ 2 and A = 5.0 × 0.5 ∼ 12.5 × 0.5 (cm 2 ).…”

The use of multiple transmitters (Tx) has been an attractive solution for enabling free-positioning wireless power transfer (WPT) in a large area. One of the key challenges in such multi-Tx WPT systems is the cross-coupling between Tx coils. This letter proposes a compact self-decoupled Tx coil solution for multi-Tx WPT systems. The measured cross-coupling between Tx coils has been reduced by 95% compared to conventional coil designs. Additionally, an integration method for a compensation inductor with the main Tx coil is proposed. Therefore, the coil design proposed in this letter facilitates creation of fully modular and scalable Tx coils for multi-Tx WPT systems. The proposed designs are experimentally verified in a laboratory prototype.

Nowadays the groundbreaking tools of contactless energy transfer reveals new opportunities to supply portable devices with electrical energy by eliminating cables and connectors. One of the important applications of such technology is the energy providing to electric and hybrid vehicles, (EV) and (HEV). These contribute to the use of cleaner energy to protect our environment. In the present paper, after exposing the available contactless energy transfer (CET) available systems, we examine the appropriateness of these systems for EV. After such exploration, it is shown that the most suitable solution is the inductive power transfer (IPT) issue. We analyze such procedure in general and indicate its main usages. Next, we consider the practice of IPT in EV and the different option in the energy managing in EV and HEV concerning battery charging. Following, we review the modes of using the IPT in immobile case and in on-road running. Following, the modeling issues for the IPT system escorting the vehicle structure are then exposed. Lastly, the electromagnetic compatibility (EMC) and human exposure analyses are assessed involving typical appliance.
