“…This ICWCS focuses on exploring the efficacy of DD coils compared to circular pad and rectangular pad coils, as they generate both horizontal and vertical flux components, exhibiting optimal features across various pad configurations. The afore-mentioned studies and [6,9,22] point out that the DD coil is advantageous for DWCS because of the following: it is relatively more tolerant to misalignment than circular and rectangular coils, has a lower flux leakage, and exhibits a higher coupling coefficient. Hence, these coils become more efficient and effective in power transfer.…”

“…To improve coupling between transmitter and receiver coils, several magnetic couplers have been suggested. According to some studies, the percentage efficiency, especially for inductive power transmission, can exceed 90% [6]. Also, in the study [7], the plausible cost savings gained were estimated via the reduced carbon footprint of passenger vehicle mobility, with the widespread adoption of dynamic wireless power transfer on roads expected in coming decades.…”

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.

“…The concept of mutual inductance calculation coefficients, introduced in [8], guides the design of magnetic couplers for electric vehicles, and a prototype was developed for validation. While there is relatively less research on MSWPT systems suitable for semiconductor wafer foundries [9,10], steady progress has been observed in the research on coil and embedded magnetic core structures for both transmission and pickup sections [11]. However, the majority of current research is concentrated on flat-type [12] and omnidirectional WPTs [13,14], with limited studies on track-type transmitter (Tx) track systems and embedded magnetic core structures.…”

To tackle the complex wireless power supply requirements in the Automated Material Handling System (AMHS) of semiconductor wafer factories, this paper presents a design method for a magnetic coupling mechanism based on a Multi-Segment Wireless Power Transfer (MSWPT) system for dynamic wireless power supply in segmented track configurations. Firstly, the track is approached using Inductive Power Transfer (IPT) technology combined with an LCC-S resonant structure transmitter (Tx). Following this, the feasibility of the H-type pickup is assessed through magnetic and electrical circuit analyses, which leads to the preliminary determination of the pickup dimensions by means of finite element magnetic and thermal simulations. Furthermore, an analysis of the mutual inductance drop is conducted under various track structure parameters during track crossing and curve negotiation operation conditions. Secondly, a dual-coil winding method is proposed to reduce the insulation stress on the PCB board. Additionally, a method for calculating the wire length and a design process for the overall parameters of the pickup are derived. Finally, two Txs and a 1.5 kW power receiver (Rx) were designed to verify the mutual inductance fall under the aforementioned conditions. During low-speed full-load operations, a constant-voltage output was achieved through the proposed dual-loop PI control strategy, thereby meeting the requirements for a constant-voltage output in industrial applications.
