Source device and method for controlling magnetic field using two source resonators in wireless power transmission system

摘要

A source device and a method for controlling a magnetic field using two source resonators in a wireless power transmission system are provided. A device configured to control a magnetic field, includes resonators configured to form the magnetic field to transmit power to another device. The device further includes a magnetic field shape determining unit configured to determine a shape of the magnetic field. The device further includes a phase changing unit configured to change a phase of at least one of the resonators to form the magnetic field in the determined shape.

1. A source device configured to control a magnetic field, the source device comprising:
a plurality of source resonators configured to form the magnetic field to transmit power to one or more target devices; a processor configured to
verify a number of the one or more target devices and position of the one or more target devices, anddetermine a shape of the magnetic field in predetermined shapes of the magnetic field based on the number of the one or more target devices and the position of the one or more target devices to optimize transmission rates between the source device and the one or target devices; and a phase changing unit configured to change a phase of at least one of the plurality of source resonators to form the magnetic field in the determined shape.
