Title (EN) MULTI-NODE WIRELESS POWER TRANSMISSION SYSTEM USING MAGNETIC RESONANCE INDUCTION AND WIRELESS CHARGING DEVICE
(FR) SYSTÈME DE TRANSMISSION DE PUISSANCE SANS FIL À NŒUDS MULTIPLES UTILISANT UNE INDUCTION PAR RÉSONANCE MAGNÉTIQUE, ET DISPOSITIF DE CHARGEMENT SANS FIL
(KO) 자기공진유도 방식을 이용한 멀티노드 무선 전력 전송 시스템 및 무선 충전기기
Abstract: front page image
(EN)The present invention relates to a multi-node wireless power transmission system using magnetic resonance induction, which can efficiently charge multiple wireless charging devices, and to a wireless charging device, comprising a step of the wireless power transmission device receiving information from multiple wireless charging devices and selecting a target device to be charged based on the information, and a step of turning on/off the power reception function of the wireless charging devices using an adaptive matching network which can control or adjust the matching of a switch that is installed on a power conversion unit in the wireless charging device. As a result, selective charging is possible by controlling the power reception function so as to be turned on/off while maintaining the power in the wireless charging devices that are not the target wireless charging device, and the wireless charging devices waiting to be charged can be used without inconvenience.
(FR)L'invention concerne un système de transmission de puissance sans fil à nœuds multiples utilisant une induction par résonance magnétique qui permet de charger efficacement de multiples dispositifs de chargement sans fil, ainsi qu'un dispositif de chargement sans fil. Au cours d'une première étape, le dispositif de transmission de puissance sans fil reçoit des informations provenant de multiples dispositifs de chargement sans fil et choisit un dispositif cible à charger en fonction de ces informations, tandis qu'une autre étape consiste à activer/désactiver la fonction de réception de puissance des dispositifs de chargement sans fil en utilisant un réseau de mise en correspondance adaptatif qui peut commander ou ajuster la correspondance d'un commutateur installé sur une unité de conversion de puissance dans le dispositif de chargement sans fil. Il est ainsi possible d'effectuer un chargement sélectif en commandant la fonction de réception de puissance en l'activant/désactivant tout en conservant la puissance dans les dispositifs de chargement sans fil différents du dispositif de chargement sans fil cible, les dispositifs de chargement sans fil en attente de chargement pouvant être utilisés sans aucune gêne.
(KO)본 발명은 다수의 무선 충전기기를 대상으로 선택적 충전을 할 수 있는 자기공진유도 방식을 이용한 멀티노드 무선 전력 전송 시스템 및 무선 충전기기에 관한 것으로서, 무선 전력전송 장치가 다수의 무선 충전기기로부터 정보를 수신하여 이러한 정보를 바탕으로 충전하고자 하는 대상 기기를 선택하고, 무선 충전기기의 전력 변환부에 설치된 스위치를 제어하거나 매칭을 조정할 수 있는 적응형 매칭 네트워크를 이용하여 무선 충전기기의 전력수신 기능을 ON/OFF한다. 이에 따라 충전 대상 기기가 아닌 다른 무선 충전기기들의 전원을 유지한 채로 전원수신 기능만을 ON/OFF 제어할 수 있으므로 선택적 충전이 가능함과 동시에 충전 대기중의 무선 충전기기들을 불편없이 사용할 수 있다.
