    摘要： An electrostatic coupling type contactless electric power supply device of this present invention comprising: an electrode for electric power supply and a high-frequency power source section provided on a fixed section, an electrode for electric power reception and a received electric power converting section provided on a movable section, and a resonance inductor forming a series resonant circuit, wherein it further comprises: a voltage detection means that detects the traveling wave voltage of the traveling wave from the high-frequency power source section to the series resonant circuit and in the reverse direction the reflected wave voltage of the reflected wave provided between the high-frequency power source section and the series resonant circuit, an auxiliary voltage detection means that detects in a contactless manner the received voltage generated at the electrode for electric power reception provided on the fixed section, and a calculation control means that calculates the load side impedance based on the traveling wave voltage and the reflected wave voltage, determines the resonance state based on the received voltage, and variably controls at least the output frequency or output voltage of the high-frequency power source section. From this, the operating stability of the current consumer on the movable section is higher while being able to simplify the electric circuit on the movable section side, and this can be smaller and lighter, which contributes to reducing the supplied electric power and lowering equipment costs.

    摘要： Provided is a wireless power supply system that supplies AC power to a power reception apparatus by using resonance of an electromagnetic field between a power transmission element and a power reception element. The wireless power supply system includes a changing circuit that changes a frequency of AC power supplied to the power transmission element, and a control device including (A) a frequency changing unit that adjusts the changing circuit to change the frequency of AC power supplied to the power transmission element in a manner capable of being controlled, (B) a frequency measurement unit that measures a first frequency and a second frequency when a state of power supply to the power reception apparatus varies between a state in which AC power is actually supplied and a state in which AC power is not supplied in accordance with the changing of the frequency of AC power, and (C) a frequency determination unit that determines the frequency of AC power during supply of AC power to the power reception apparatus to a frequency between the first frequency and the second frequency. According to this, the frequency of AC power during power supply can be appropriately adjusted, and thus it is possible to efficiently supply power to the power reception apparatus.
