Abstract:
(EN) A module for wireless power transmission in a magnetic resonance mode is provided. The module for wireless power transmission in a magnetic resonance mode according to one embodiment of the present invention, which is provided with a radiator for wireless power transmission disposed adjacently to a conductor, comprises: a radiator unit comprising the radiator for wireless power transmission; and a magnetic shielding unit disposed on one side of the radiator unit and provided with a magnetic shielding layer, which comprises fragments of an Fe-based alloy, which have been fragmented so as to improve the flexibility of the shielding unit and reduce the generation of eddy currents, and a dielectric filled in at least some of the gaps formed between some adjacent fragments among the fragments so as to reduce eddy current generation, thereby preventing an interruption by the conductor to the transmission/reception of the radiator and improving the properties of the radiator. Configured as such, the present invention blocks the effect of a magnetic field on components, such as a portable terminal device, or a user using same at the time of transmitting/receiving wireless power signals in a magnetic resonance mode, minimizes or prevents an interruption by the conductor, which may be adjacently disposed therearound, to the transmission/reception of the power signals, and can significantly improve the efficiency of wireless power transmission in a magnetic resonance mode by significantly improving the properties of the radiator.
(FR) L'invention concerne un module de transmission de puissance sans fil dans un mode de résonance magnétique. Le module de transmission de puissance sans fil dans un mode de résonance magnétique selon un mode de réalisation de la présente invention, lequel comporte un radiateur de transmission de puissance sans fil disposé de manière adjacente à un conducteur, comprend : une unité de radiateur comprenant le radiateur de transmission de puissance sans fil; et une unité de blindage magnétique disposée d'un côté de l'unité de radiateur et comportant une couche de blindage magnétique, laquelle comprend des fragments d'un alliage à base de Fe, lesquels ont été fragmentés afin d'améliorer la flexibilité de l'unité de blindage et de réduire la génération de courants de Foucault, et un diélectrique injecté dans au moins certains des vides formés entre des fragments adjacents parmi les fragments afin de réduire la génération de courants de Foucault, évitant ainsi une interruption par le conducteur de la transmission/réception du radiateur et améliorant les propriétés du radiateur. Ainsi conçue, la présente invention bloque l'effet d'un champ magnétique sur des composants, comme un dispositif terminal portatif, ou un utilisateur l'utilisant au moment de la transmission/réception de signaux de puissance sans fil dans un mode de résonance magnétique, minimise ou évite une interruption par le conducteur, lequel peut être disposé de manière adjacente autour de ceux-ci, de la transmission/réception des signaux de puissance, et peut améliorer significativement le rendement de transmission de puissance sans fil dans un mode de résonance magnétique en améliorant significativement les propriétés du radiateur.
