“…The design of the U ferrite core can reduce the flux leakage by feeding back the magnetic fluxes into the core and to the secondary side https://doi.org/10.31436/iiumej.v23i1.1663 [17]. Therefore, it is proven that the pair design of U ferrite cores at the primary and secondary sides was the best design that gave high magnetic flux and led to the maximum power efficiency of WPT, as mentioned by Pathipati et al [13]. The extension of this research is that there is a pair where the ferrite core is not at both sides simultaneously.…”

“…The extension of this research is that there is a pair where the ferrite core is not at both sides simultaneously. Previous research by Pathipati et al [13], who also investigated the ferrite core, proposed that all the designs have a ferrite core in both the primary and secondary sides. Instead of using a ferrite core at both sides, this thesis investigated a different pair if one of the sides was a copper coil and the other was a ferrite core.…”

The technology of dynamic Wireless Power Transfer (WPT) has been accepted in the Electric Vehicle (EV) industry. Recently, for a stationary EV charging system, the existence of a ferrite core improves power efficiency. However, for dynamic wireless charging, the output power fluctuates when the EV moves. Two main obstacles that must be dealt with is air-gaps and misalignment between the coils. This paper investigates clear design guidelines for fabrication of an efficient Resonant Inductive Power Transfer (RIPT) system for the EV battery charging application using a ferrite core. Two different geometry shapes of ferrite core, U and I cores, will be investigated and tested using simulation and experimental work. The proposed design was simulated in JMAG 14.0, and the prototype was tested in the laboratory. The expected output analysis from these two techniques was that the power efficiency of the ferrite pair should first be calculated. From the analysis and experimental results, it is seen that the pair of ferrite cores that used a U shape at the primary and secondary side provides the most efficient coupling in larger air-gap RIPT application with 94.69% on simulation JMAG 14.0 and 89.7% from conducting an experiment. ABSTRAK: Teknologi Alih Kuasa Wayarles (WPT) dinamik telah diterima pakai dalam Kenderaan Elektrik (EV). Baru-baru ini, kewujudan teras ferit dalam sistem pengecasan pegun EV dapat meningkatkan kecekapan kuasa. Namun, kuasa pengecasan ini akan berubah apabila EV bergerak bagi sistem pengecasan wayarles secara dinamik. Dua halangan utama yang harus ditangani adalah ketidakjajaran dan jarak antara dua gegelung. Kajian ini merupakan garis panduan yang jelas mengenai rekaan fabrikasi dan kecekapan sistem Alih Kuasa Induktif Resonan (RIPT) bagi aplikasi pengecasan bateri EV menggunakan teras ferit. Dua bentuk geometri teras ferit, iaitu teras U dan I telah dikaji dan diuji menggunakan simulasi dan eksperimen. Rekaan ini telah disimulasi menggunakan JMAG 14.0 dan prototaip diuji di dalam makmal. Kedua-dua teknik ini diharapkan dapat menghasilkan kecekapan kuasa yang sama. Dapatan kajian menunjukkan kedua-dua teras ferit pada sisi primer dan sekunder berbentuk U mempunyai gandingan paling efisien bagi jarak paling besar antara 2 gegelung menggunakan aplikasi RIPT dengan 94.69% simulasi JMAG 14.0 dan 89.7% secara eksperimen.

“…In the earlier design of IPT, most researchers preferred the solenoid coupler as a pick-up coil for EV stationary and dynamic charging systems due to the strong magnetic field and the magnetic flux concentrating inside the ferrite core [21,31,[34][35][36][37]. However, the solenoid type is not favoured any more in EV wireless charging systems due to the induced magnetic flux pattern that disperses surrounding the coil and core.…”

Inductively coupled power transfer (ICPT) is a technology that is implemented to charge electric vehicles (EVs) wirelessly. Some developments from the past years indicate that this promising charging method has the potential to replace wired charging methods. Thus, some aspects of designing ICPT need to be discussed and considered to develop an optimal system. However, most reviews from the previous articles focused on the developments of ICPT systems in the scope of EV charging. This study not only reviews current developments and topical issues and challenges in high-power ICPT systems, but also presents several techniques for analysing the system as well as further developments for wireless EV charging adapted from the other electromagnetic field applications. This study will assist readers to analyse any proposed ICPT systems using current methods of analysis and to tackle highlighted topical issues presented from the previous technical papers.
