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： A control system includes a phase shift unit configured to provide a phase difference between a first switching clock signal and a second switching clock signal, a power transmission coil, a switching circuit configured to switch an input voltage based on the first switching clock signal and apply the switched voltage to the power transmission coil, a power reception coil configured to receive electric power output from the power transmission coil by electromagnetic field coupling, a wireless transmission unit configured to wirelessly transmit the second switching clock signal and output a third switching clock signal, and a rectifier circuit configured to rectify a voltage input from the power reception coil by switching the voltage based on the third switching clock signal and apply the rectified voltage to a load. A voltage input from the power reception coil to the rectifier circuit and the third switching clock signal have different phases.

摘要： A wireless electrical power transmission system includes a panel having a recessed area for receiving a wireless power transmitter, such as an electric field resonant transmitter. The panel has a first outer surface and a second outer surface opposite the first outer surface, with a thickness defined between the first and second outer surfaces. The recessed area is formed in the first outer surface, and the recessed area has a depth that is less than the thickness of the panel. Electrical wiring is coupled to the wireless power transmitter and passes through an opening formed in the panel, which opening is accessible from the recessed area, and the electrical wiring is in communication with an electrical power source.

摘要： A system and method for wirelessly transmitting power through a window comprising transmitting and receiving coils or electrodes, which are embedded in or otherwise mounted with respect to flexible polymer suction cups. The transmitting and receiving coils or electrodes are arranged opposite one another on the interior and exterior of the window, respectively, via attachment of the suction cups thereon. Power provided to the transmitting coil or electrode, for example from an auxiliary power adapter of a vehicle, may be transmitted through the window by inductive coupling or capacitive coupling. The power provided to the receiving coil or electrode can then be used to power external devices such as taxi roof signs, lighted advertising signs, spotlights and other auxiliary off-road lights, trailer tail lights, emergency and warning lights, speakers, cameras, battery chargers, and packages of scientific instruments for measuring air pollutants and various environmental factors such as weather parameters.

摘要： A first power transfer circuit in a first power transfer apparatus and a second power transfer circuit in a second power transfer apparatus are configured to be electrically symmetrical to each other. In transfer of electric power from one of the first and second power transfer apparatuses to the other of the first and second power transfer apparatuses, a controller drives a first switching circuit and a second switching circuit using a parallel resonant frequency of a complex resonant circuit as a reference frequency of an operating frequency. The controller changes the operating frequency to a frequency higher than the reference frequency or a frequency lower than the reference frequency if a duty ratio is maximized when transmitted electric power is lower than target electric power, which is a control target value, during the driving at the reference frequency.

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.
