Abstract

Wireless power transmission through inductive coupling, also known as resonant inductive coupling, is an innovative technology that enables the transfer of electrical energy without physical connections. Rooted in the principles of electromagnetic induction, this technology establishes a magnetic field between two coils, thereby facilitating efficient power transfer from the transmitter to the receiver. This paper addresses the design of wireless power transmission systems, highlighting their growing significance across a range of applications. With the proliferation of IoT devices and electric vehicles, the demand for convenient charging solutions is rapidly increasing, underscoring the economic and practical importance of these technologies. The focus of this paper is specifically on wireless power transfer via inductive coupling for charging purposes. Key design considerations include optimising coil size and shape, managing voltage and current levels, and selecting the appropriate system frequency. Both circular and rectangular coils were designed and used for simulation purposes. Maximum power transfer was achieved within the 20 mm to 50 mm range, where voltage and current losses were minimal. Circular coils proved to be more practical, as their performance is unaffected by the orientation of the primary and secondary coils. In contrast, rectangular coils are significantly influenced by the alignment of the coupling between the transmitter and receiver.
