Special Issue Information

Dear Colleagues,

Wireless power transfer (WPT) technology is revolutionizing a wide range of modern applications, from electric vehicles and industrial automation to consumer electronics and autonomous drones, by providing exceptional convenience, safety, and reliability. As the demand for more efficient and resilient WPT systems accelerates, new challenges emerge. These include the pursuit of greater transfer efficiency, extended transmission ranges, and enhanced robustness in environments with multiple sources of interference. This Special Issue welcomes pioneering research in this area and innovative solutions that address these challenges. We seek contributions from fields such as dynamic decoupling mechanisms, advanced coupling and compensation networks, adaptive control methods, and novel system designs. Submissions that tackle practical challenges, introduce breakthrough solutions, or bring forward disruptive innovations in WPT technology are highly encouraged. Potential topics include, but are not limited to, the following:

  • Novel theories of wireless power transfer technology;
  • Multi-disturbance decoupling;
  • The design of optimized coupling structures;
  • Advanced control strategies;
  • Compensation networks;
  • Foreign object detection;
  • New modulation schemes;
  • Special applications of wireless power transfer;
  • Dynamic wireless charging;
  • Electromagnetic compatibility and shielding.

This paper presents a high-efficiency wireless power transfer (WPT) architecture employing a resonant inductive coupling to power smart sensor nodes in remote or sealed environments, where conventional power delivery is unfeasible. The system integrates a photovoltaic (PV) energy source with a step-down DC-DC converter based on the LM2596 buck regulator to adjust the voltage from the PV. The proposed conditioned power system supplies the entire electronic circuit consisting of a PWM modulator based on an NE555, which drives an IR2110 gate driver connected to a Class D power amplifier. The amplifier excites a pair of high-Q resonant coils designed for mid-range inductive coupling. On the receiver side, the inductively coupled AC signal is rectified and regulated through an AC-DC conversion stage to charge a secondary energy storage unit. The design eliminates the need for physical electrical connections, ensuring efficient, contactless energy transfer. The proposed system operates at a resonant frequency of 24.46 kHz and achieves up to 80% transmission efficiency at a distance of 113 mm. The receiver provides a regulated DC output between 4.80 V and 4.97 V, sufficient to power low-consumption smart sensors. Full article

A multivector direct model predictive control (DMPC) scheme is proposed for the dual three-phase permanent magnet synchronous machine (DTP-PMSM) drive system to achieve closed-loop control for both fundamental current tracking and harmonic current minimization. The proposed multivector DMPC scheme employs four active voltage vectors, including two large vectors and two basic vectors for implicit modulation. Moreover, the control optimization problem is formulated as a four-dimensional quadratic programming problem, which is suitable for real-time implementation. The proposed multivector DMPC scheme enables fast and accurate tracking of the fundamental current as well as effective suppression of harmonic currents in both the fundamental and harmonic subspaces. In addition, a Kalman filter observer is incorporated to enhance robustness against model uncertainties and disturbances. Experimental results on a DTP-PMSM test bench verify that the proposed multivector DMPC scheme effectively reduces torque ripple, improves current quality, and enhances both steady-state and transient performance of the system.
