Abstract

Magnetic Resonance Coupling-based Wireless Power Transfer (MRC-WPT) systems are influenced by multiple interrelated parameters—such as coil geometry, operating frequency, coupling distance, and alignment—that collectively affect efficiency, particularly in compact, portable electronic applications. While many existing studies focus on optimizing these parameters individually, few explore their interdependent behavior. This research investigates a dual-coil, air-core MRC-WPT system to determine the optimal configurations of magnetic resonance parameters for efficient power transfer in portable electronics. The study systematically examines the interdependencies among key parameters to identify their optimal values. A model of the MRC-WPT system, adapted from existing literature, serves as the foundation for this research. The primary objectives are to evaluate how magnetic resonance parameters influence the efficiency of MRC-WPT systems in portable devices, identify ideal configurations for enhanced efficiency, and develop a prototype system to experimentally assess performance under various conditions. The results reveal the optimal coil configuration for an MRC-WPT system operating at a resonant frequency of 3.4 MHz. The developed prototype achieved a wireless power transfer output of 2.35 V and 0.0106 A, resulting in an overall system efficiency of 0.070% using resistive loads.
