Efficient magnetic resonant coupling wireless power transfer with a novel conical-helix resonator

[摘要] To improve the performance of magnetic resonant coupling wireless power transfer (MRC-WPT), a novel conical-helix resonator is designed and optimized for efficient power transfer. Simulation is conducted to investigate characteristics of the proposed resonator and compare with the traditional helix-helix coils. It has been observed that the performance of the MRC-WPT system with conical-helix resonator is superior to that with the helix-helix resonator. Experimental prototype is set up for validation. The results indicate that the voltage transferred to the receiving coil is largely improved for the MRC-WPT system with the proposed resonator when distance between transmitter and receiver varies.
