Power transmission test via a repeater antenna by using non-contact electric power transmission evaluation system capable of simulating high-speed driving conditions

Abstract

　This paper provides the evaluated results of transmitting efficiency concerning about non-contact electric power transmission via a repeater antenna using magnetic resonance method under high-speed driving conditions. First, we evaluated transmitting efficiency in installing a repeater antenna between a transmitting antenna and a receiving antenna to fully understand the effects of the repeater antenna. Second, we also experimentally evaluated and simulated transmitting efficiency at zero velocity when the repeater antenna was installed in our own evaluation system. Finally, we found out that transmitting efficiency decreased at a peripheral velocity over 60 km/h when both a transmitting side rotor and a repeater antenna rotated at the same peripheral velocity.
