To provide a non-contact power supply facility that includes a plurality of power supply lines arranged side by side along a movement route of a mobile body and that appropriately synchronizes AC currents flowing in the power supply lines with low material cost and installation man hour.SOLUTION: A non-contact power supply facility comprises a coupling unit 5 that electromagnetically couples a target power supply line 3T with an adjacent power supply line 3N. A target power supply device 2T comprises: a phase detection unit 8 that detects an induction current phase that is a phase of an induction current flowing in the target power supply line 3T due to electromagnetic induction via the coupling unit 5 with an AC current being supplied to the adjacent power supply line 3N by an adjacent power supply line 2N; an AC current generation unit 6 that generates an AC current to be supplied to the target power supply line 3T; and a phase control unit 7 that controls the AC current generation unit 6 so that a phase of the AC current supplied to the target power supply line 3T approaches an induction current phase detected by the phase detection unit 8.SELECTED DRAWING: Figure 7
【課題】移動体の移動経路に沿って並ぶように配置された複数の給電線を有する非接触給電設備において、資材コストや設置工数を低減しつつ、各給電線を流れる交流電流を適切に同期させる。【解決手段】対象給電線3Tと隣接給電線3Nとを電磁結合する結合ユニット5を備える。対象電源装置2Tは、隣接電源装置2Nにより隣接給電線3Nに交流電流が供給されている状態で、結合ユニット5を介した電磁誘導により対象給電線3Tに流れる誘導電流の位相である誘導電流位相を検出する位相検出部8と、対象給電線3Tに供給する交流電流を生成する交流電流生成部6と、対象給電線3Tに供給される交流電流の位相が位相検出部8により検出された誘導電流位相に近づくように、交流電流生成部6を制御する位相制御部7とを備える。【選択図】図7
