Abstract

This paper proposes a single-wire power transfer (SWPT) system using distributed parameter resonant coil. An accurate equivalent circuit is proposed by establishing the distributed parameter circuit model of the single-layer air-core solenoid coils and the single wire. The vector and amplitude distribution of spatial electric field are depicted from simulation results. Experimental results of a prototype SWPT system are presented at different distances. The system can transfer 350W with 60% efficiency at 30m, and transfer 300W with 42% efficiency at 70m.
