  • Non-contact power supply device
    Patent number: 9705565
    Abstract: A non-contact power supply device comprises: a primary winding (101); and a secondary winding (201) to which an electric power is supplied from an alternating current power supply via the primary winding, wherein an impedance characteristic of Z1 with respect to a frequency is such that a minimal value is provided in the proximity of a frequency of a fundamental wave component of the alternating current power supply and another impedance characteristic of Z2 with respect to the frequency is such that the frequency of the fundamental wave component is provided between the frequency which is nearest to the frequency of the fundamental wave component and at which a maximal value is provided and the frequency which is nearest to the frequency of the fundamental wave component and at which the minimal value is provided.
