Evaluation Equipment of Noncontact Electric Power Transmission for a High-Speed Running Vehicle and the Evaluation of Transmission Efficiency at High Efficient Arrangements

This paper deals with a new fabricated equipment to investigate a possibility of noncontact power feeding under a high speed relative motion with. First, we designed magnetic resonant type transmitting and receiving antennas and confirmed the transmission efficiency of paired antennas. Moreover, we clarified the effects of adjacent transmitting antennas on transmission efficiency from both static experiment and calculation with equivalent circuit. In the paper, we have demonstrated that the transmitting efficiency does not fall down even when the rotor having eight transmission antennas rotates up to a peripheral velocity of 72 km/h.
