Abstract
(EN)
A device has a plurality of coils arranged along a perimeter within the device, where each coil has a winding configured to be coupled to a power converter through a resonant capacitor, and forms a resonator with the resonant capacitor. The device has also a connection core which is magnetically coupled to the plurality of coils. Furthermore, the device has a plurality of power converters, where each power converter is coupled to one of the plurality of coils, and is configured such that a current flowing through the winding of the coil has the same frequency as other winding currents in the device, and the phase angle of the current is approximately equal to the space angle of the coil, so a rotating magnetic field is formed in a space around the device.

Un dispositif comprend une pluralité de bobines agencées le long d'un périmètre à l'intérieur du dispositif, chaque bobine ayant un enroulement conçu pour être couplé à un convertisseur de puissance par l'intermédiaire d'un condensateur résonant, et forme un résonateur avec le condensateur résonant. Le dispositif comprend également un noyau de connexion qui est couplé magnétiquement à la pluralité de bobines. En outre, le dispositif comprend une pluralité de convertisseurs de puissance, chaque convertisseur de puissance étant couplé à une bobine de la pluralité de bobines, et étant conçu de telle sorte qu'un courant circulant à travers l'enroulement de la bobine a la même fréquence que d'autres courants d'enroulement dans le dispositif, et l'angle de phase du courant est approximativement égal à l'angle d'espace de la bobine, de telle sorte qu'un champ magnétique rotatif est formé dans un espace autour du dispositif.
