Effect of Operating Frequency on Resonant Wireless Power Transfer

Wireless Power Transfer (WPT) technologies based on Magnetic Resonance Coupling (MRC-WPT) have certainly emerged as a leading alternative to traditional charging techniques in recent years. However, a thorough investigation is required to characterize the various design parameters for the MRC-WPT system. The perception of consumed input power from the source, as well as the system's output power for various coil radii while operating at various frequencies, have been used to explore the efficiency of this technique. This work elucidated the theoretical and analytical investigation accompanied by simulation findings to show the system performance dependence on the operating parameters. The MRC-WPT system's overall power transfer efficiency (PTE) is shown to be highly frequency selective. Hence, the efficacy of the MRC-WPT system has been represented to unveil the suitability of wireless charging systems.
