Abstract

Cette invention concerne le domaine technique de l'alimentation électrique et propose un appareil d'alimentation électrique sans fil. Dans l'état actuel de la technique, il est nécessaire de relier un transformateur de courant par un câble, ce qui rend l'appareil d'alimentation électrique difficile à déplacer, et, lors de l'utilisation d'une batterie, lorsque l'énergie électrique est épuisée, l'utilisateur ne peut plus travailler. L'appareil d'alimentation électrique sans fil faisant l'objet de cette invention comprend un émetteur de courant et un récepteur de courant. L'émetteur de courant possède des bobines émettrices entourant un magnétiseur et un circuit d'oscillation HF connecté aux bobines émettrices. Le récepteur de courant est constitué par une bobine réceptrice entourant le magnétiseur. Il peut convertir un courant continu ou un courant alternatif en tension de courant continu, par l'intermédiaire du circuit oscillant HF qui convertit une tension HF s'appliquant aux bobines émettrices de l'émetteur de courant et émise par le magnétiseur et il induit un signal de courant HF sous l'action du magnétiseur dans le récepteur de courant, la bobine réceptrice émettant le signal, ce qui produit le transfert sans fil de courant.
