Special Issue Information

Dear Colleagues,

As one of the epoch-making techniques in recent years, wireless power transfer (WPT) has significantly changed energy-accessing patterns considering it not only shakes off messy wires and sparking hazards but also yields high convenience and reliability. Possessing the distinct features of high efficiency and safety, as well as automation and electrical isolation, WPT can readily deliver energy from the transmitter to the receiver through the magnetic or electric fields without the metallic connection, resulting in increasing numbers of academic and industrial researchers getting involved in this emerging area. This Special Issue offers a timely opportunity for academic researchers and industrial engineers to present, discuss, and exchange their latest results and findings for WPT technologies regarding topology design, electromagnetic field theory, and power electronics and applications, as well as future development directions.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • New materials for WPT;
  • Compensation networks;
  • Converters and inverters;
  • Analytical and finite element methods;
  • Electromagnetic compatibility and safety;
  • Detection techniques and sensors;
  • Emerging applications for WPT;
  • Overview papers on WPT techniques and development.

I look forward to receiving your contributions.

Wireless power transfer is a widely applied technology whose market and application areas are growing rapidly. It is considered to be a promising supplement to the conductive charging of electrical vehicles (EVs). Wireless charging provides safety, convenience, and reliability in terms of mitigating issues related to wiring, risk of tearing, trip hazards, and contact wear inherent to the conductive charging. A variety of coil structures have been researched for EV charging applications; however, most of them were of the symmetrical type. This work analyzes systems of coils possessing ferromagnetic backing with non-symmetrical geometries and compares them with the conventional symmetrical ones. Numerical FEM simulation was applied in the research. The numerical models were verified analytically and experimentally. The impact of air-gap length, longitudinal displacement, number of turns, and width of the ferrite bars on coupling factor was investigated. The results suggest that coil systems with non-symmetrical structures of ferromagnetic backings are a good alternative to the conventional symmetrical structures for wireless electrical vehicle charging applications.

This paper proposes a novel approach to simultaneously identifying multiple critical parameters in a wireless power transfer (WPT) system, such as the resonant frequency, mutual inductance, and load resistance, solely from the primary side. The key is to adopt a primary-side-switch-controlled capacitor (SCC) to ensure that the imaginary part of the input impedance is only caused by the secondary-side reflected impedance at three predesigned frequencies. The DSP controller then samples and processes the primary voltage and current using a gradient descent algorithm to derive the above parameters. After the identification, the SCC adjusts its equivalent capacitance based on the secondary-side practical resonant frequency to ensure a zero-phase angle (ZPA), thereby significantly improving the compatibility of the WPT system with unknown receivers. Compared to the previous frequency-sweeping method, the proposed approach is simpler and more suitable for deployment on the controller. Finally, experimental results demonstrate that the identification error of mutual inductance and resonant frequency are within 7.5% and 2.68%, respectively. Full article
