Advancements in Three-Coil Wireless Power Transfer: A Path to Flexible Energy Solutions

The evolving landscape of wireless power transfer demands not only performance but also flexibility to adapt to diverse application needs. This paper explores the enhanced flexibility of three-coil wireless power transfer systems, which offer significant advantages in terms of adaptable configurations and responsive tuning to various operating conditions. We detail a series of innovations in coil design that allow these systems to maintain optimal performance across a range of distances and alignments. By incorporating an intermediate coil, these systems achieve superior magnetic coupling and can dynamically adjust to changes in energy demand and spatial configurations, making them ideal for scenarios where conventional WPT systems fall short. It demonstrates the system's robustness under various environmental conditions, showcasing its potential to revolutionize energy transfer in settings from consumer electronics to industrial applications.
