Abstract

This chapter delves into the fundamental principles and circuit modeling of wireless power transfer (WPT) technology, covering both near-field and far-field techniques. It explores the magnetic flux phenomenon in 2-coil inductive links, key parameters like coupling coefficient and mutual inductance, and efficient design considerations for optimizing power transfer efficiency. The text also discusses multi-coil systems, DC-AC converters, and AC-DC rectifiers, providing a comprehensive understanding of WPT system components. Additionally, it examines rectification architectures, adaptive energy reception techniques, and system-level energy management strategies, offering insights into both fundamental and state-of-the-art solutions. The chapter concludes with an overview of advanced techniques for secure, efficient, and reliable operation of WPT technologies in real-world applications.
