Wireless Power Transfer: Enhancing Efficiency Through Resonant Inductive Coupling

Abstract

Wireless Power Transfer (WPT) technology, particularly through Resonant Inductive Coupling (RIC), has garnered significant attention due to its potential to deliver power efficiently over moderate distances without physical connectors. RIC leverages the natural resonance between transmitter and receiver coils, enabling high-efficiency energy transfer even when the coils are not perfectly aligned. This paper explores the fundamental principles of RIC, highlighting the importance of resonant frequency, coil design, and alignment in optimizing power transfer efficiency. Current applications of RIC, such as in wireless charging for consumer electronics, electric vehicles, and implantable medical devices, are discussed, showcasing its versatility and practical benefits. The paper also addresses the challenges facing RIC, including efficiency at longer distances and integration into existing infrastructure. Future directions in RIC research, such as the development of metamaterials and standardized charging systems, are considered as potential solutions to these challenges. As research progresses, RIC is poised to revolutionize various industries by providing a more convenient, reliable, and sustainable method of power delivery, marking a significant advancement in WPT technology.
