“…The skin depth of aluminum alloy is calculated using δ = 2 ω 0 µ 0 σ to be approximately equal to 0.3 mm. Nevertheless, to ensure effective shielding over a wide operating frequency range, the aluminum shield thickness is set to be six times the skin depth, i.e., 1.8 mm, based on earlier work by the authors in [60]. In addition, to reduce eddy current losses in the aluminum shield, a vertical gap of 5 mm is maintained between the ferrite layer and the aluminum shield.…”

“…Nevertheless, increasing the number of turns increases the amount of conductor wires used in coil construction and increases the ESR of the coil. The number of turns for both primary and secondary coils was then selected to be 16 based on earlier work by the authors in [60], as shown in Figure 6, and the coils' outer dimensions were set to 800 × 600 mm 2 . The proposed inductive link design is summarized in Table 3.…”

Dynamic wireless power transfer (DWPT) systems are becoming increasingly important for on-the-move electric vehicle (EV) charging solutions, to overcome range anxiety and compensate for the consumed energy while the EV is in motion. In this work, a DWPT EV charging system is proposed to be implemented on a straight road stretch such that it provides the moving EV with energy at a rate of 308 Wh/km. This rate is expected to compensate for the vehicle’s average energy consumption and allow for additional energy storage in the EV battery. The proposed charging system operates at an average power transfer efficiency that is higher than 90% and provides good lateral misalignment tolerance up to ±200 mm. Details of the proposed system’s design are presented in this paper, including EV specifications, inductive link and compensation network design and power electronic circuitry.
