  • Patent number: 10128652
    Abstract: A method of stabilizing a DC electricity network, the network including a DC voltage source powering electrical loads that are connected in parallel to terminals of the voltage source and each of which is to receive a current or voltage setpoint. The method stabilizes the network by regulating setpoints applied to the loads by a virtual stabilization impedance generated at terminals of each load, the virtual impedances being dimensioned to stabilize the network in desired operating points and in given configurations of the network including a state in which at least one load is inactive or has failed and a state in which the stabilization of a load is inactive. Each virtual impedance is generated by a non-linear regulation loop acting on the setpoint for the corresponding load.

  • Patent number: 9825470
    Abstract: A multi-source power converter is proposed to permit bidirectional DC to AC conversion from n (n?2 and n?) DC voltage sources to an AC load with a reduced number of switches, and DC to DC conversion. Both single and three phases AC load are considered. The proposed topology consists in a single stage of conversion, and therefore a high efficiency can be expected for the system. Any type of DC sources can be used in the system (fuel-cell, battery, ultra-capacitor, photo-voltaic cells, DC bus, DC to DC or AC to DC converter, etc.). The AC load can be either single or three phases (single-phase AC grid/microgrid, three-phase electric machines, induction machine, synchronous machine, etc.). There is no requirement for the n DC voltage source values; they can be equal or different and they can be used individually or together by the converter to generate the AC output. If different DC voltage values are used, the converter can be controlled to generate a multi-level AC voltage.

    Abstract: A multi-source power converter is proposed to permit bidirectional DC to AC conversion from n (n?2 and n?N) DC voltage sources to an AC load with a reduced number of switches, and DC to DC conversion. Both single and three phases AC load are considered. The proposed topology consists in a single stage of conversion, and therefore a high efficiency can be expected for the system.

  • Publication number: 20050028640
    Abstract: The invention proposes a method of controlling the gear change for a vehicle having at least two driving wheels, each driven by an electric motor M via a gear change mechanism having at least two reduction gears, a sensor for sensing the rotation speed of the driving wheel, in which the gear change on the two driving wheels is carried out in accordance with the following sequence: in an initial phase, releasing the current gear on a wheel referred to as the “operated” wheel RM, and stopping it in the neutral position, changing the revolution speed of the motor so as to synchronize it as a function of the reduction of the gear to be engaged on the operated wheel RM, using as an estimate of the speed of the vehicle a speed information item that is obtained from another driving wheel, referred to as the “sensor” wheel RC, engaging the intended gear on said “operated” wheel RM, then, in a successive phase, changing the gear on said other driving wheel with reversal of the roles of sensor wheel RC and operated whe

  • Patent number: 5347543
    Abstract: This device in which the elements are linked by two information transmission lines (2, 3) and each of which includes information sending and reception circuits (4, 5), linked to a protocol handler (6), is characterized in that the reception circuit (5) of each element (1) comprise three comparators (7, 8, 9), a first comparator (7) receiving the signals transiting on the two lines (2, 3), a second comparator (8) receiving the signals transiting on a line (2) and a third comparator (9) receiving the signals transiting on the other line (3) and, interposed between the output of these comparators (7, 8, 9) and the information input (RC) of the handler (6), a circuit (10) for selective connection of the output (R0) of the first comparator (7) or of the output of a circuit for logically combining the outputs (R1, R2) of the second and third comparators (8, 9), to the input of the protocol handler (6), under the control of the latter as a function of the state of the signals present at its input, in order to permit

  • Patent number: 5031176
    Abstract: This interface includes three comparators, the inputs of the first comparator being connected to the two transmission lines, one of the inputs of the second comparator being connected to one of the transmission lines and the other input of this comparator being connected to a bias voltage generator, one of the inputs of the third comparator being connected to the other transmission line and the other input of this comparator being connected to the bias voltage generator. The outputs of the comparators are connected to inputs of a multiplexer whose output is connected to the remainder of the circuits of the station, and the control inputs of the multiplexer are connected to the output of defect detecting means for detecting defects of one of the transmission lines so that the transmission lines control the multiplexer in such manner that the multiplexer selects the output of one of the comparators as a function of the state of the transmission lines.
