Abstract:
A non-contact power-feeding device (10), provided with a plurality of power-feeding units (20), a power reception unit (30), and a parameter-setting unit (40). The plurality of power-feeding units are provided with an AC power supply (21) and a power-feeding element (22) for feeding the AC power outputted from the AC power supply. The power reception unit is provided so as to be capable of moving relative to the plurality of power-feeding units and is equipped with a power reception element (31) for receiving AC power in a non-contact manner from the opposing power-feeding element. The parameter-setting unit sets a parameter, which is at least one of the power-feeding frequency of each of the AC power supplies of the plurality of power-feeding units and the impedance of a resonance circuit formed in the power-feeding unit side and/or the power reception unit side, in accordance with the electrical characteristics of the respective power-feeding elements of the plurality of power-feeding units.
