  • 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.

  • Patent number: 8827631
    Abstract: The invention relates to a turbine engine that includes at least first and second lift turbine stacks with transverse flow. The shafts of adjacent turbines in the first stack are connected by a first coupling device adapted for compensating space misalignments, and the shafts of adjacent turbines in the first stack are connected by a second coupling device adapted for compensating for space misalignments. The turbine engine includes a device for supporting the first and second turbine stacks, which is symmetrical to said plane, and a control device adapted for permanently maintaining the symmetry between the first and second turbine stacks relative to the plane, and for maintaining the rotation speeds of the first and second turbine stacks at equal values in opposite rotation directions.
