Mid-range Wireless Power Transmission in Space

Abstract: Wireless power transmission using magnetic resonance is discussed. Theoretical transmission efficiency was derived as a function of impedance ratio r and RF frequency ω. Impedance matching is possible to attain maximum transmission efficiency for various coupling coefficient cases. Power feeding demonstration to an electric powered helicopter was conducted to develop an efficient, compact, and light-weight resonator as a receiver and to show the validity of the theoretical prediction. In this system, dielectri… Show more

“…However, its main problem, which is common to all relevant theoretical models of the literature [40,52,60,[62][63][64], is the size of the used mutual inductance matrices that hinders its practical implementation when a great number of coupled resonators needs to be deployed. So far, several approximate methods with converging results have been used to determine the PTE of WPT systems [14,21,24,26,73,[105][106][107][108][109]. In this paper, the CSM method is proposed, which constitutes a refined version of the scattering matrix method first presented in [73].…”

“…Due to variation of the mutual inductance, power transfer efficiency may be seriously degraded without proper impedance matching [1,2]. Hence, some adaptive impedance-matching methods were proposed [3,4].…”
