Special Issue "Research on Wireless Power Transfer System"
Deadline for manuscript submissions: 20 October 2022 | Viewed by 8324
Wireless power transfer (WPT) Technology has been researched over the years for improving the quality of the life in terms of, for example, convenience and safety when supplying power to load systems or charging the energy system is required. Due to the increase of applications, the need for more applicable methods and techniques arises in order to properly design the WPT system and enhance the merits of WPT technology.
The Special Issue invites original research papers to address new technology of WPT systems in order to improve the performance of the WPT system and extend the application of WPT technology. Additionally, authors are encouraged to submit papers addressing the state-of-the-art and recent advancements in the areas, providing useful guidelines for future research directions.

Title: Comparative Analysis of Wireless Power Transmission System with Two Transmitting Coils for Correction of Misalignment of Transceiver Coils

Abstract: Misalignment of the transmitting coil and the receiving coil is a major cause of lowering the efficiency of the wireless power transfer (WPT) system. Misalignment is not necessarily perfect because it is affected by the user's skill in using the device. In this paper, we propose a method to analyze and correct the output voltage of WPT according to the coupling coefficient change due to lateral misalignment in a multi-transmitter WPT system with SS topology. In general, the misalignment lowers the coupling coefficient between the transceivers and causes a decrease in output power and efficiency. At this time, if the impedance of the transmitter due to the change of the coupling coefficient is adjusted to be the same as before the misalignment occurs, it is possible to achieve significant transmission efficiency correction by minimizing reactive power even in the misalignment state. This control method, which requires multiple transmitters for the control method, is suitable for a transmitter having a multi-coil structure and can be applied to a double-D(DD) type coil commonly used for charging electric vehicles (EVs). The proposed control method was analyzed and verified through HFSS simulation, MAXWELL simulation, and PSIM simulation.

Abstract: The article presents results for numerical and analytical analysis of Wireless Power Transfer system (WPT) consisting of transmitting and receiving planar spiral coils. Two types of coils (circular and square) were included in the analysis. Two coil systems were also considered: periodic and checkerboard. The difference between the proposed systems lies in the different method of winding the coils. In the periodic system, all coils are wound in the same direction. But in the checkerboard-type system turns are wound in the opposite direction. The influence of the type of the coils, the winding direction, the number of turns and the distance between the coils on the efficiency of the WPT system was compared. The analysis covered a wide range of frequency from 100 kHz to 1000 kHz. The Finite Element Method (FEM) with the use of periodic or antiperiodic boundary conditions was used for the analysis. In the periodic model, greater efficiency was obtained with circular rather than square coils (e.g. 5% -20% for 1 MHz). In the checkerboard-type configuration, for a smaller radius of the coil, system efficiency was greater in square coil models than in circular coil models. On the other hand, with larger radius of the coil, the efficiency of the system was comparable regardless of the type of the coil. Proposed WPT system could be used to charge electric devices as the wireless power transfer system. The results indicate at which system parameters wireless energy transfer is possible.
