To reduce the influence of a leakage magnetic field on surrounding of a system during electric power transmission.SOLUTION: A ground power feeding device 2A transmitting power to a vehicle 3 in a non-contact manner comprises a control device 22 operating the ground power feeding device 2A in such a manner that a phase of a magnetic field generated during power feeding of the ground power feeding device 2A is the opposite phase of a phase of a magnetic field generated during power feeding of another ground feeding device 2B when the ground feeding device 2A is required to transmit power while a ground power feeding device 2B paired with the ground power feeding device 2A transmits power.SELECTED DRAWING: Figure 6A
【課題】送電時における漏洩磁界がシステム周囲に与える影響を低減する。【解決手段】車両3に非接触で電力を送電する地上給電装置2Aは、地上給電装置2Aと対になる他の地上給電装置2Bの電力送電時に地上給電装置2Aによって電力を送電する必要が生じたときは、地上給電装置2Aの電力送電時に発生する磁界の位相が、他の地上給電装置2Bの電力送電時に発生する磁界の位相とは逆位相となるように、地上給電装置2Aを動作させる制御装置22を備える。【選択図】図6A
