To provide a mobile wireless power supply system performing non-contact power supply to a power reception coil 30 mounted on a mobile body from a plurality of power transmission coils 20 spaced and disposed on a ground side, and having improved a power supply efficiency at a time when the power reception coil 30 and the power transmission coils 20 do not face.SOLUTION: A mobile wireless power supply system has a relay magnetic material 40 disposed between power transmission coils 20 spaced and disposed, and this relay magnetic material 40 relays at least a part of magnetic flux interlinking with a power reception coil 30 not facing the power transmission coils 20, and the power transmission coils 20. In this system, even when the power transmission coils 20 and the power reception coil 30 do not face, the magnetic flux interlinking the power transmission coils 20 and the power reception coil 30 increases by an existence of the relay magnetic material 40, so that a reduction of a power supply efficiency can be suppressed.SELECTED DRAWING: Figure 1
【課題】地上側に離間して配置された複数の送電コイル20から移動体に搭載された受電コイル30に非接触給電を行うシステムであって、受電コイル30及び送電コイル20が正対していないときの給電効率を改善した移動体用ワイヤレス給電システムを提供する。【解決手段】離間して配置された送電コイル20の間に配置された中継用磁性体40を有し、この中継用磁性体40が、送電コイル20に正対していない受電コイル30とその送電コイル20とに鎖交する磁束の少なくとも一部を中継する。このシステムでは、送電コイル20と受電コイル30とが正対していない場合でも、中継用磁性体40の存在により送電コイル20及び受電コイル30に鎖交する磁束が増加するため給電効率の低下が抑えられる。【選択図】図1
