Apparatus and method for wireless power transmission

摘要

An apparatus and method for efficiently, wirelessly transmitting a power to a plurality of target devices are provided. A wireless power transmitter may include: a source resonator configured to wirelessly transmit energy to a target device with at least one target resonator, the energy being stored in a capacitor; and a feeding unit configured to generate an induced current flowing in the source resonator in the same direction as a direction of an input current flowing in a transmission line, the feeding unit being electrically connected to the capacitor and forming a closed loop with the source resonator.

1. A wireless power transmitter comprising:
a source resonator configured to wirelessly transmit energy to a target device with at least one target resonator, the energy being stored in a capacitor; and a feeding unit configured to generate an induced current flowing in the source resonator in the same direction as a direction of an input current flowing in a transmission line, the feeding unit being electrically connected to the capacitor and forming a closed loop with the source resonator, wherein, within a first region, a direction of a first magnetic field formed based on the input current is identical to a direction of a second magnetic field formed based on the induced current, and within a second region between the source resonator and the feeding unit, a direction of the first magnetic field is different from a direction of the second magnetic field.
