A Novel Parallel Double Helix Loop Resonator for Magnetic Coupled Resonance Wireless Power Transfer
A novel parallel double helix loop resonator for magnetic coupled resonance wireless power transfer (WPT) is proposed in this paper. The various characteristics are investigated by using simulation and experiment. Compare to a same geometry size traditional structure helix loop resonator, the proposed resonator could reduce the resistance loss about 48% and improve the maximum power transfer efficiency about 8% within the strong coupled region. On the other hand, the coupling efficiency of proposed resonator used WPT system is also increased. Finally, for increase the power transfer efficiency at the region of outside of the strong coupled, a pair of matching loops are used to match the transmitting and receiving resonator to the optimal port impedance at varying distance and the measurement results shows the maximum power transfer efficiency that the system could achievable by using traditional structure helix loop resonator and parallel double helix loop resonator are 34% and 57% at the distance of 20 cm, respectively.
