摘要： An electrode unit is used in a power transmitting device or a power receiving device of a wireless power transmission system based on an electric field coupling method. The electrode unit includes: a first electrode to which a first voltage is applied when power is transferred; a second electrode to which a second voltage antiphase to the first voltage is applied when power is transferred; and a third electrode spaced apart from the first and second electrodes, the third electrode having a third voltage whose amplitude is less than amplitudes of the first and second voltages when power is transferred. The first and second electrodes are arranged along an electrode installation plane. At least a portion of the third electrode does not overlap the first and second electrodes as viewed from a direction perpendicular to the electrode installation plane.

摘要： Devices and systems of inductive-capacitive (LC) coil-resonators that can be embedded easily inside high-voltage insulation discs are provided. Each LC coil-resonator comprises spiral conductive tracks fabricated or printed in the form of at least two layers of planar spiral windings on electrically non-conductive materials. The planar conductive windings on at least two parallel layers may be connected to form a closed winding. The distributed inductance associated with the planar spiral windings and the distributed capacitance between the layers of the conductive tracks form an equivalent LC coil-resonator. When these LC coil-resonators are embedded in some or all of the insulation discs in a high-voltage insulation rod, they form the relay coil-resonators for wireless power transfer.

摘要： A power transmitter wirelessly transmits electric power to a power receiver that includes a reception antenna. The power transmitter includes: an inverter circuit; a transmission antenna which sends out the AC power having been output from the inverter circuit; and a control circuit which, based on measurement values of voltage and current to be input to the inverter circuit, determines a value of a control parameter defining an output voltage from the inverter circuit and controls the inverter circuit by using the determined value of the control parameter. When at least one of the measurement values of voltage and current to be input to the inverter circuit changes, the control circuit changes the value of the control parameter based on the measurement values of voltage and current so that a voltage to be output from the power receiving circuit is maintained within a predetermined range.
