Special Issue Information

Dear Colleagues,

Wireless power transfer (WPT) incredibly effectuates energy transmission cordlessly. This epoch-making technique could change our traditional energy consumption patterns in various applications, such as portable electronics, implanted medical devices, electric vehicles, solar-powered satellites, and so forth. Since the WPT techniques are advantageous due to their flexibility, movability, and free positioning, many researchers and industries have been trying to develop WPT systems.

WPT techniques could be divided into two categories according to their transmission range: (1) short-range WPTs, such as inductive power transfers and capacitive coupled power transfers. (2) long-range WPTs, such as laser power transfers and microwave power transfers.

This Special Issue in Electronics aims to focus on the most recent research in the development, design, implementation, modeling, and validation of WPT systems for various applications. Authors are encouraged to submit original research articles addressing the originality of the work, as well as practical aspects and implementations. Topics of WPT technologies that are of interest include, but are not limited to:

  • Consumer Electronics;
  • Electric vehicles;
  • Medical and biological devices;
  • Application of WBG devices in WPT systems;
  • Simultaneous wireless power and data transfers.
  • Long-range WPT systems;
  • Ambient energy harvesting.

The recent studies on magnetically coupled resonant bidirectional wireless power transfer (MCR-BWPT) systems disregard the challenges posed by nonlinearity, discrete switching action, and hybrid properties within the system. This research focuses on the D-LCL resonant compensation topology MCR-BWPT system. The switch tube’s switching state dictates the division of various working modes and the determination of the switching conditions between them. The coupling relationship between the continuous dynamic characteristics of the system and discrete events and the constrained conditions of the system are derived. The Hybrid System Description Language (HYSDEL) is used to build the Mixed Logic Dynamic (MLD) model of the system. The MLD model is employed as the prediction model, and the hybrid model predictive controller of the MCR-BWPT system is constructed according to the quadratic performance index. Finally, to verify the accuracy of the MLD model and the feasibility of the control strategy, the simulation model of the MLD model is established in MATLAB/Simulink. The study’s findings show that, in terms of response time at system startup and power fluctuation suppression, the approach put forward in this research performs better than both the conventional bilateral dual-phase-shift control strategy and the PQ-based bilateral power control strategy. The MCR-BWPT system can operate more steadily now that PQ’s bidirectional power control technique is in place. The system’s forward and reverse transmission efficiency is increased by 0.29% and 0.32% compared to the conventional bilateral dual-phase-shift control approach; the increases are 0.28% and 0.09%, each compared to the bilateral power control strategy based on PQ.

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.
