To provide a technique that is able to decrease power pulsation.SOLUTION: A non-contact power supply system during traveling supplies power to a traveling vehicle by using a plurality of primary coils 112 installed in a traveling direction of a road, and a secondary coil 212 mounted on a vehicle 200. If M is an integer of 2 or greater, the secondary coil is an M-phase coil composed of M coils. The M coils have: coil ends Ce extending in forward and backward directions of the vehicle; and a main coil portion Mc extending in a width direction of the vehicle. The magnetic resistance of a magnetic path through which the magnetic flux of each coil end Ce passes is greater than the magnetic resistance of a magnetic path through which the magnetic flux of the main coil portion Mc passes.SELECTED DRAWING: Figure 4B
【課題】電力脈動を減少させることができる技術を提供する。【解決手段】走行中非接触給電システムは、道路の進行方向に沿って設置された複数の1次コイル112と、車両200に搭載された2次コイル212とを用いて車両の走行中に車両に給電する。Mを2以上の整数としたとき、2次コイルは、M個のコイルで構成されたM相コイルである。M個のコイルは、車両の前後方向に沿って延びるコイルエンドCeと、前記車両の幅方向に沿って延びる主コイル部Mcとを有しており、コイルエンドCeの磁束が通る磁路の磁気抵抗が、主コイル部Mcの磁束が通る磁路の磁気抵抗よりも大きくなるように構成されている。【選択図】図4B
