PROBLEM TO BE SOLVED: To inexpensively provide a power supply system, a power-receiving device and a non-contact power supply system in the atmosphere, in a substance of which the transmission loss of an electromagnetic wave signal is larger than that in the atmosphere, in fresh water of which the salt concentration is 0 to 10% or in seawater, or in a combination thereof.SOLUTION: In a non-contact power supply device and a non-contact power supply system, a power-feeding coil and a power-receiving coil are put in a non-saturated state, the power-feeding coil and the power-receiving coil are put in a non-resonant state or in a non-resonant state close to a resonant state, a load Q value thereof is made 50 or less, and a voltage fluctuation rate at load is made 50% or less, otherwise a combination of the above arrangements is embodied. In the power-feeding coil, a magnetic excitation current is driven by an AC electrical power source with a frequency of 50 Hz to over 41 MHz, whereby the power-feeding coil is caused to radiate a high-output fluctuating magnetic field. The radiated fluctuating magnetic field enables non-contact power supply in a near-distance, and enables magnetic wave communications in a middle distance as well.SELECTED DRAWING: Figure 1

    【課題】大気中、電磁波信号の伝搬損失が大気中での伝搬損に比較して大きい物質中、塩分濃度が0%から10%までの真水中もしくは海水中、あるいはこれらの組み合わせの中で、給電装置、受電装置、および非接触給電システムを安価に提供する。【解決手段】非接触給電装置および非接触給電システムは、給電コイルと受電コイルとを、非飽和状態とし、非共振状態とし、共振状態に近い非共振状態とし、負荷Q値が50以下とし、負荷時電圧変動率が50%以下であり、あるいはこれらを組合わせとし、給電コイルに周波数が50Hzから41MHz超までの交流電源によって励磁電流を駆動することによって、前記給電コイルから高出力の変動磁界を放射させ、前記放射された変動磁界によって、近距離間での非接触給電を可能とし、中距離間での磁力波通信を合わせて可能にする。【選択図】図1
