Title
(EN) A WIRELESS POWER TRANSFER SYSTEM
(FR) SYSTÈME DE TRANSFERT D'ÉNERGIE SANS FIL
Abstract
(EN)
The present invention is a wireless power transfer system (10) for charging batteries in a wireless manner, wherein said wireless power transfer system (10) comprises an inverter (150) connected to a first end where DC input voltage is provided and arranged to transform said input voltage into sinusoidal waveform at a f1 frequency; and a transmitter circuit (160) associated with the inverter (150) which receives the voltage in sinusoidal waveform received from said inverter (150); said transmitter circuit (160) comprises a first winding (161) for providing transferring of the voltage, received from the inverter (150), in a wireless manner; said wireless power transfer system (10) further comprises a receiver circuit (210) having a second winding (211) associated with the battery (300) to be charged; a control unit arranged to monitor the phase difference angle between the first voltage and the inverter (150); and the control unit is arranged to gradually increase the f1 frequency until the phase difference exceeds 0 and to provide continuation of the power transfer process with the obtained f1 frequency when the phase difference exceeds 0 or is equal to 0.
(FR)
La présente invention concerne un système de transfert d'énergie sans fil (10) pour charger des batteries d'une manière sans fil, ledit système de transfert d'énergie sans fil (10) comprenant un onduleur (150) connecté à une première extrémité où est appliquée une tension d'entrée CC est fournie et agencé pour convertir ladite tension d'entrée en une forme d'onde sinusoïdale à une fréquence f1; et un circuit émetteur (160) associé à l'onduleur (150) qui reçoit la tension en forme d'onde sinusoïdale reçue dudit onduleur (150); ledit circuit émetteur (160) comprend un premier enroulement (161) pour assurer un transfert de la tension, reçue de l'onduleur (150), d'une manière sans fil; ledit système de transfert d'énergie sans fil (10) comprend en outre un circuit récepteur (210) ayant un second enroulement (211) associé à la batterie (300) à charger; une unité de commande conçue pour surveiller l'angle de différence de phase entre la première tension et l'onduleur (150); et l'unité de commande est conçue pour augmenter progressivement la fréquence f1 jusqu'à ce que la différence de phase dépasse 0 et pour assurer la poursuite du processus de transfert de puissance avec la fréquence f1 obtenue lorsque la différence de phase dépasse 0 ou est égale à 0.
