Description
Summary:This paper newly proposes a configuration of magnetic coupling in wireless power transform using parallel line power feeder. Previous researches mentioned that coil design and optimization of circuit parameters are necessary for strong magnetic coupled resonance. Then, these constraints prevent expansion of coverage area of wireless power transfer to electric portable devices, and electric vehicles. In order to make breakthrough against these limitations, this paper introduces parallel line as a feeder. The frequency of the electromagnetic wave is selected at 13.56 [MHz] in high frequency (HF) band, which is suitable for strong magnetic coupled resonance. Fundamental characteristics are evaluated by using equivalent circuits which are referred to the previous works. Theoretical analysis asserts that impedance transform is necessary in a power source and load circuits. Computer simulation evaluates a mutual inductance between primary and secondary coils, and optimum value of load resistance is clarified. Finally, input impedance and S-parameter are evaluated when power source circuit and feeder circuit are magnetic coupled resonance, these results imply that enhancement of power transfer efficiency is a further study.
