The invention relates to a position information transmission apparatus, a position information transmission method, and a moving object. The purpose of the present invention is to reduce the influence of an AC magnetic field for power transmission on the transmission of a position signal when non-contact power transmission is performed between a moving body and a ground device by magnetic field resonance coupling. A position information transmission device (6, 6 ') is provided on one of a ground-side device (2) and a moving body that performs non-contact power transmission by magnetic field resonance coupling with the ground-side device, and is provided with: an AC power generation circuit (61) that generates AC power; an AC magnetic field generation circuit (62) that generates an AC magnetic field as a position signal when AC power is applied; and a power inflow suppression unit that suppresses the inflow of induced electromotive force into the AC power generation circuit, said induced electromotive force being caused by an AC magnetic field emitted from the power transmission-side resonance circuit (43) for non-contact power transmission.

    本发明涉及一种位置信息发送装置、位置信息发送方法及移动体。在移动体与地上侧装置之间进行基于磁场谐振耦合的非接触电力传输时,降低电力传输用的交流磁场给位置信号的发送带来的影响。位置信息发送装置(6、6’)设置于地上侧装置(2)和与地上侧装置之间进行基于磁场谐振耦合的非接触电力传输的移动体中的一方,具备:交流电力产生电路(61),使交流电力产生;交流磁场产生电路(62),在被施加了交流电力时作为位置信号而使交流磁场产生;及电力流入抑制部,抑制由为了非接触电力传输而从送电侧谐振电路(43)发出的交流磁场引起的感应电动势向交流电力产生电路的流入。
