Abstract:
A power transmitting unit (PTU) transmits a power wirelessly based on a location of a power receiving unit (PRU). The PTU determines whether the PRU is located within a charging area of the PTU based on frequency information corresponding to an inflection point detected on a curve of electrical characteristics of a resonator of the PTU.
Abstract:
An apparatus and a method for wireless power reception include converting a received wireless power to a wireless power for charging using a synchronous rectifier and a direct current/direct current (DC/DC) converter having a structure providing a high efficiency and low heat generation even when a high charging current is supplied.
Abstract:
A method of operating a wireless power transmission apparatus includes receiving, from a wireless power reception apparatus, information on an operating power of a micro control unit (MCU) of the wireless power reception apparatus and information on an output of a direct current-to-direct current (DC/DC) converter of the wireless power reception apparatus; determining whether a charging power is to be transmitted to the wireless power reception apparatus based on the received information on the output of DC/DC converter; and transmitting, to the wireless power reception apparatus, an MCU operating power calculated based on the received information on the operating power of the MCU in response to a determination that the charging power is not to be transmitted to the wireless power reception apparatus.

Abstract:
An authentication of a power transmitting unit (PTU) includes determining whether an access right to an external device is present in a power receiving unit (PRU) based on identification information of the PRU, and network-connecting the PRU to the external device in response to a result of the determining being that the access right is present in the PRU.
