“…Polarized geometries, on the other hand, namely the double-D (DD), double-D quadrature (DDQ) and bipolar coils, utilize the parallel components of the magnetic field for power transfer, which provides higher coupling across large separation distances between the primary and secondary sides [25,32,33]. However, the authors in [34][35][36] report significantly low coupling values during misalignments, and hence poor misalignment tolerance, between primary-and secondary-side DD coils due to the inherent null coupling point [37]. This motivates the utilization of multi-coil structures such as the DDQ and bipolar coils to leverage on the individual advantages of each coil geometry while offering additional design degrees of freedom to overcome their disadvantages [38,39].…”

Dynamic wireless charging (DWC) systems enable electric vehicles (EVs) to receive energy on the move, without stopping at charging stations. Nonetheless, the energy efficiency of DWC systems is affected by the inherent misalignments of the mobile EVs, causing fluctuations in the amount of energy transmitted to the EVs. In this work, a multi-coil secondary-side inductive link (IL) design is proposed with independent double-D (DD) and quadrature coils to reduce the effect of coupling fluctuations on the power received during misalignments. Dual-sided inductor–capacitor–capacitor (LCC) compensation networks are utilized with power and current control circuits to provide a load-independent, constant current output at different misalignment conditions. The LCC compensation components are tuned to maximize the power transferred at the minimum acceptable coupling point, kmin. This compensates for the leaked energy during misalignments and minimizes variations in the operating frequency during zero-phase angle (ZPA) operation. Simulations reveal an almost constant output power for different lateral misalignment (LTMA) values up to ±200 mm for a 25 kW system, with a power transfer efficiency of 90%. A close correlation between simulation and experimental results is observed.

“…There are various DWCS topologies. In [18], regarding DWCS, the authors explore the utilization of the two predominant coil configurations in IPT systems at the simulation level. This study has involved two distinct pad types-namely, the distributed dynamic pad (DDP) and rectangular pads positioned on the side of the car.…”

Wireless charging (WC) has gained popularity for the charging of electric vehicles in recent years of research, particularly dynamic wireless charging systems (DWCSs). Among the different topologies of DWCSs, this paper focuses on an inductively coupled wireless charging system (ICWCS). In this ICWCS, double-D (DD) coils create horizontal and vertical flux components between different pad configurations, which show optimal features in contrast to circular pad coils. In this work, the three-dimensional (3D) finite element technique (FEM) is used to establish the proposed design to observe the coupling coefficient, while the system design’s performance is evaluated using a circuit simulator. In the simulation, the proposed DD coil configuration is used for both the transmitter and receiver sides. It provides the maximum coupling coefficient and efficiency at perfect alignment when using an in-between air gap of 166 mm and six I-type ferrite bars on the transmitter side and five I-type ferrite bars on the receiver side. The coupling coefficient and system parameters, such as power and efficiency, are considered for different misalignments in the proposed configuration. The results of this work satisfy the Society of Automotive Engineers (SAE) J2954 Class 3 criteria. The best results obtained are on account of optimizing the ferrite core, which is achieved by varying its length and width. While varying the ferrite core’s dimensions, 0.2451, as the optimal k value, is obtained at the effective width and length of 57.5 mm and 400 mm, respectively. The simulation results of the Ansys Maxwell 3D software prove the feasibility of the proposed structure.
