The study in this paper proposes a novel resonator design that uses tightly coupled parallel coils to reduce the equivalent self-resistance in coupled magnetic resonance wireless power transfer. Depending on the characteristics of the tightly coupled parallel-connected coils, the proposed resonator can offer significantly reduced resistance with very little self-inductance loss. A double-layer spiral coil structure is used for resonator design and evaluating its characteristics. Measured results show that a resonator consisting of two identical, tightly coupled parallel double-layer spiral coils can match the Q factor of a conventional double-layer spiral coil with the same number of turns, even though its equivalent resistance is approximately 75% less. Moreover, because of the lower equivalent self-resistance and optimum port impedance, the novel structure resonator can transfer higher power than the conventional resonator with the identical efficiency is confirmed by the simulation results. |
