Abstract[English]
The invention relates to a wireless power transfer (WPT) device configured to be mounted in an electric vehicle for charging a traction battery of the electric vehicle. The WPT device comprises a WPT receiver coil, a rectifier and at least two safety switching units coupled in parallel rectifier switching units of the full bridge rectifier. A control unit controls the at least two safety switching units to be open during a charging operation of the WPT device and to be closed at least during powering up of the WPT receiver coil and/or in case of a damage or malfunction of the WPT device or any element thereof.[French]
L'invention concerne un dispositif de transfert d'énergie sans fil, WPT, configuré pour être monté dans un véhicule électrique pour charger une batterie de traction du véhicule électrique. Le dispositif WPT comprend une bobine réceptrice WPT, un redresseur et au moins deux unités de commutation de sécurité couplées dans des unités de commutation de redresseur parallèles du redresseur en pont complet. Une unité de commande commande les au moins deux unités de commutation de sécurité à ouvrir pendant une opération de charge du dispositif WPT et à fermer au moins pendant une mise sous tension de la bobine réceptrice WPT et/ou en cas d'un endommagement ou d'un dysfonctionnement du dispositif WPT ou de tout élément de celui-ci.
