Abstract: The electronics industry is experiencing a paradigm shift due to its transition from wired to wireless charging. This transformation is set to reach new heights with the increasing adoption of wireless charging across various applications. To embrace these emerging applications, addressing technical challenges and advancing wireless power transfer (WPT) technologies becomes imperative. This seminar will start with a comprehensive examination of existing low-frequency WPT systems, exploring the stability challenges they face and introducing effective strategies to overcome them. Moreover, a highly efficient printed-circuit-board (PCB) resonator for megahertz WPT systems will be presented, showcasing its potential to advance WPT technologies into high-frequency regions. Finally, these key technologies will be summarized, and the prospects for future research will be outlined.
