讲座摘要：
Wireless Power Transfer (WPT) is becoming a key enabling technology in modern power electronics, with increasing applications in electric vehicles, biomedical implants, and industrial automation. This tutorial presents the next-generation WPT systems, integrating recent advances in magnetic coupler design, nanocrystalline materials, and system-level modeling and control for both static and dynamic scenarios.
The tutorial begins with key design principles and experimental insights into magnetic couplers, emphasizing how nanocrystalline materials enhance thermal stability and power density. Compared to conventional MnZn ferrites, Fe-based nanocrystalline alloys exhibit lower core losses, higher saturation flux density, and superior thermal equilibrium characteristics. Thermal runaway models and simplified lumped-parameter approaches will be introduced to help predict and mitigate thermal instability in high-power applications.
The second part focuses on system modeling and dynamic optimization. Unified full-load discrete-time modeling and generalized state space averaging modeling will be presented for both static and dynamic WPT systems. The tutorial will also give compensation topology selection, impedance matching, and real-time excitation optimization in multi-coil segmented dynamic WPT systems. Particular attention will be given to dynamic coil-to-coil mutual inductance variation, phase angle control, and adjacent-coil current coordination to maintain high transmission efficiency.
This tutorial provides practical knowledge across materials, topology, modeling, and control. It is suitable for researchers, engineers, and graduate students who wish to gain a complete understanding of how to build high-performance, thermally stable, and dynamically optimized WPT systems for the future.
