  • Patent number: 10083942
    Abstract: An electronic power device including: a first electronic power component in which all the electrodes are arranged at a first main face of the first electronic power component; and an electric contact element in which a first main face is arranged against the first main face of the first electronic power component and which includes plural separate electrically conductive portions to which the electrodes of the first electronic power component are electrically connected. The first electronic power component and the electric contact element together form a stack such that a first lateral face of each of the portions of the electric contact element, substantially perpendicular to the first main face of the electric contact element, is arranged against at least one metallization of a support forming an electric contact of the first electronic power component.
    Type: Grant

  • Patent number: 9991191
    Abstract: Electronic power device comprising: an active layer comprising several lateral and/or semi-lateral components for which the electrodes are located on a front face of the active layer; an interconnection structure comprising several conducting portions to which component electrodes are connected, and located in contact with these electrodes extending parallel to the active layer; a support comprising a front face on which electrically conducting tracks are located, and in which: the interconnection structure is located between the active layer and the support, the conducting portions being placed in contact with the conducting tracks, or the active layer is placed between the interconnection structure and the support, the conducting portions comprising parts extending next to the active layer and connected to the conducting tracks.

  • Patent number: 9570987
    Abstract: The invention relates to a voltage converter (100), including: a plurality of two-way conversion cells (303), each cell comprising a primary circuit (307, Wp), and a secondary circuit (308, Ws) that is insulated from the primary circuit, wherein each circuit can be separately activated in order to supply an output voltage from the converter; and at least one control circuit (306) configured to, in a first operating mode, control the activated cells in order to transfer electrical energy from the primary circuit to the secondary circuit, and control the inactivated cells in order to transfer electrical energy from the secondary circuit to the primary circuit.
