This non-contact power feeding device (100) is provided with: a plurality of primary coils (112) installed in a road; and a power transmission control unit (150) that uses some of the plurality of primary coils (112) as power transmission implementing coils (PSC) to perform power transmission from the power transmission implementing coils (PSC) to a secondary coil (212) mounted on a vehicle (200).The power transmission control unit (150) uses a specific primary coil (CC) different from the power transmission implementing coils (PSC) among the plurality of primary coils (112) to reduce a leakage magnetic flux generated by the energization of the power transmission implementing coils (PSC). Instead of using the specific primary coil (CC), the secondary coil (212) may be used to limit the leakage magnetic flux.
一种非接触供电装置(100),包括:多个一次线圈(112),所述多个一次线圈设置于道路;以及送电控制部(150),所述送电控制部将多个一次线圈(112)中的一部分的一次线圈作为送电实施线圈(PSC)使用,并且执行从送电实施线圈(PSC)向装设于车辆(200)的二次线圈(212)的送电。送电控制部(150)使用多个一次线圈(112)中的与送电实施线圈(PSC)不同的特定的一次线圈(CC),来减小由于向送电实施线圈(PSC)通电而产生的漏磁通。也可以代替使用特定的一次线圈(CC)而使用二次线圈(212)来限定漏磁通。
