The Exploring The Potential Of Mid-Range Wireless Power Transfer Using Resonance Inductive Coupling

Abstract

This paper investigated mid-range wireless power transfer using resonance inductive coupling. The researchers built a prototype circuit capable of wirelessly transmitting power up to 16 cm using a 9V DC supply and oscillator for the transmitter, testing different receiver coil configurations. They analyzed factors affecting transmission efficiency, including coil type, number of turns, and distance between transmitter and receiver. Key findings showed that a 30-turn magnetic coil receiver achieved the highest efficiency (~66%) at 0 cm, with efficiency decreasing as distance increased for all receiver types. The system could power multiple loads simultaneously, though with reduced efficiency, and barriers between transmitter and receiver did not significantly impact power transmission due to the resonant coupling. Overall, the study demonstrated the potential of resonance-based wireless power transfer for mid-range applications, while highlighting areas for further optimization and research.
