To make it possible to perform non-contact power transmission at an arbitrary position within a mobile range without detecting a mobile position of a mobile body and without synchronizing a drive phase of a plurality of power transmission power sources while providing a plurality of power transmission coils extending in a mobile direction at a distance from each other along the mobile direction in transmitting non-contact power to a power receiving coil in the mobile body.SOLUTION: A non-contact power transmission system S includes a power transmission control unit 4 for controlling a plurality of power transmission power sources 21 to m so that a period of time during which a magnetic field generated by one of power transmission coils 22 to m is stronger than a magnetic field generated by other power transmission coils 22-m regarding power transmission coils 22-m (m is 1 to 4) adjacent to each other along a moving direction of the mobile unit bodies 3 to n (n is 1 to 3), and other period of time during which a generated magnetic field of one of power transmission coils 22-m is weaker than a magnetic field generated by other power transmission coils 22-m alternately appear regardless of a moving position of mobile unit bodies 3-n.SELECTED DRAWING: Figure 3
【課題】本開示は、移動体内の受電コイルに非接触電力伝送するにあたり、移動方向に延びる複数の送電コイルを移動方向に沿って互いに間隔を空けて設けたうえで、移動体の移動位置を検出せず、複数の送電電源の駆動位相を同期させず、移動範囲内の任意位置で非接触電力伝送を可能にすることを目的とする。【解決手段】本開示は、移動体3−n(n=1〜3)の移動方向に沿って互いに隣り合う送電コイル22−m(m=1〜4)について、一の送電コイル22−mの発生磁界が他の送電コイル22−mの発生磁界より強い一の期間と、一の送電コイル22−mの発生磁界が他の送電コイル22−mの発生磁界より弱い他の期間と、が移動体3−nの移動位置に関わらず交互に出現するように、複数の送電電源21−mを制御する送電制御部4と、を備えることを特徴とする非接触電力伝送システムSである。【選択図】図3
