Abstract:
A wireless power transmission method includes searching for one or more routes to be used to transmit power to a reception resonator through one or more relay resonators, and converting the routes to respective one or more two-port networks. The method further includes calculating a transmission efficiency of each of the routes based on the two-port networks, and selecting a route with a highest transmission efficiency from the routes. The method further includes wirelessly transmitting power to the reception resonator through the selected route.
Abstract:
A method and an apparatus for controlling wireless power transmission are provided. An apparatus for controlling wireless power transmission includes a controller configured to determine an output voltage of a power factor correction unit based on charging information of a battery, the power factor correction unit configured to correct an input voltage into the determined output voltage, and output a variable voltage, and a resonance unit configured to transmit power converted from the variable voltage to a wireless power reception apparatus.
Abstract:
An apparatus and a method for wireless power reception are provided. A wireless power receiver includes a receiving unit configured to wirelessly receive a power. The wireless power receiver further includes a power consuming unit configured to consume the power, until a voltage applied to a load reaches a predetermined value, so that an amount of a power transferred from the receiving unit to the load is less than or equal to an initial accommodation power amount of the load.
Abstract:
A wireless charging station, an electric vehicle charged wirelessly, and a method of charging an electric vehicle are provided. A wireless charging station include a charging unit configured to transmit power wirelessly to an electric vehicle, using a source resonator installed in the charging station; and a driving unit configured to move a target resonator connected to the source resonator from a position at which the target resonator is mounted on the charging unit to an installation space of the electric vehicle, when the electric vehicle is disposed in a charging area of the charging station.
Abstract:
A reception (RX) node using mutual resonance includes a target resonator configured to receive power via mutual resonance with a source resonator; a controller configured to wake up in response to the received power, determine a point in time at which the controller woke up to be a point in time at which synchronization with other RX nodes is performed, and generate a data packet, and a sensor configured to wake up in response to the received power, sense information.
Abstract:
An interference control method of a power transmitting unit (PTU) includes determining whether the PTU is in an interference environment in which interference by a neighbor PTU occurs, and controlling a communication parameter of either one or both of the neighbor PTU and a power receiving unit (PRU) in response to a result of the determining being that the PTU is in the interference environment.
Abstract:
A magnetic field generation apparatus includes a plurality of coplanar inductors disposed to form a planar structure, wherein each of the coplanar inductors is configured to generate a magnetic field having a basis vector that is orthogonal to a basis vector of a magnetic field generated by another one of the coplanar inductors.
