To provide a technology that can simplify a device configuration while suppressing power fluctuations.SOLUTION: An in-traveling non-contact power supply system supplies power to a vehicle while the vehicle is traveling by using a plurality of primary coils 112 installed along the direction of travel on the road and a secondary coil 212 installed in a vehicle 200. The primary coil 112 is a single-phase coil. The secondary coil 212 is an M-phase coil composed of M coils. A coil of a specific phase that exists in the center of the M coils that are lined up along the front-to-back direction of the vehicle has a smaller coil area than the coils of the other phases.SELECTED DRAWING: Figure 11B
【課題】電力脈動を抑制しつつ、装置構成を簡略化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。1次コイル112は単相コイルであり、2次コイル212は、M個のコイルで構成されたM相コイルであり、車両の前後方向に沿って並ぶM個のコイルのうちの中央に存在する特定相のコイルは、他の相のコイルよりもコイル面積が小さく設定されている。【選択図】図11B
