Wireless and Smart Power Transfer – WPT Systems

Abstract

Wireless Power Transfer (WPT) has emerged as a transformative technology for energy transmission without physical connectors. From small-scale consumer electronics to large-scale industrial applications, WPT systems provide efficient, flexible, and safe power delivery. Recent advancements in smart WPT systems incorporate IoT-enabled monitoring, adaptive control, and energy optimization to improve efficiency and usability. This review paper presents an in-depth analysis of WPT technologies, including inductive, capacitive, and resonant coupling methods, along with smart power management approaches. The study also evaluates efficiency, challenges, and future directions, highlighting trends in automotive, biomedical, and industrial applications. Key contributions include a comparative evaluation of WPT methods, discussion on smart control strategies, and identification of potential research areas to enhance wireless energy transfer.
