摘要: A wireless power supply system (100) includes a power transmitter (101) and a power receiver (103). The power transmitter includes a power-transmitting coil (113) to which AC power of a frequency is input from a power source (111). The power receiver includes a power-receiving coil (121) magnetically coupled to the power-transmitting coil at a coupling coefficient, and a first power-receiving-side series element (123) coupled in series to the power-receiving coil and having imaginary impedance jZ S2i . In this wireless power supply system, the frequency and the imaginary impedance are determined so that impedance of a power-receiving side seen from the power source is independent of the coupling coefficient when the coupling coefficient changes.

摘要: A power reception coil device is a power reception coil device attached to a movable body, for wirelessly receiving power from a power transmission coil device, and includes a power reception coil portion including a conductive wire, and a nonmagnetic body disposed between the movable body and the power reception coil portion. The nonmagnetic body includes a first overhang protruding in a first direction outwardly from one end portion of a region onto which the power reception coil portion is projected in a second direction. The first direction is orthogonal to the second direction in which the power reception coil device opposes the power transmission coil device. The first overhang is longer than or equal to a maximum permissible misalignment permissible between the power reception coil portion and a power transmission coil portion of the power transmission coil device.
