To provide a technique capable of simplifying system configuration while suppressing power pulsation.SOLUTION: The running non-contact power supply system uses a plurality of primary coils 112 installed along the traveling direction of a road and a secondary coil 212 mounted on vehicle 200 to supply power to the vehicle while the vehicle is running. A primary coil 112 is a single-phase coil, and a secondary coil 212 is a two-phase coil composed of a first-phase coil and a second-phase coil. The deviation width Db between the first phase coil and the second phase coil measured in the longitudinal direction of the vehicle is preset so that the effect on power pulsation by the mutual inductance of the first phase coil and the second phase coil and the effect on the power pulsation by the difference between the maximum and minimum values of the squares of the coupling coefficients of the primary and secondary coils so as to cancel out.SELECTED DRAWING: Figure 9C
【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は第1相コイルと第2相コイルとで構成された2相コイルである。第1相コイルと第2相コイルの相互インダクタンスによる電力脈動への影響と、1次コイルと2次コイルの結合係数の2乗の最大値と最小値の差分による電力脈動への影響が打ち消されるように、車両の前後方向に測った第1相コイルと第2相コイルのずれ幅Dbが設定されている。【選択図】図9C
