    Abstract: Un arreglo para determinar el valor de voltaje de un capacitor de celda (Udc) de una celda (10´´ de un convertidor de energía de múltiples celdas comprende la celda (10´´) y una unidad de control (28). La celda (10´´) por sí misma comprende cuatro válvulas electrónicas de energía (1-4) interconectadas como un convertidor de puente completo que tiene una primera y segunda patas de fase, donde cada pata de fase comprende una conexión en serie de dos (1, 3; 2, 4) de las cuatro válvulas electrónicas de energía y donde el punto de conexión (6; 7) entre las dos válvulas electrónicas de energía de cada pata de fase se puede conectar externamente, un capacitor de celda (5) que está conectado en paralelo con la primera y segunda patas de fase, y cuatro unidades de puerta (16-19), cada una conectada con una de las válvulas electrónicas de energía (1-4) correspondientes así como con la unidad de control (28) . Cada una de las cuatro unidades de puerta (16- 19) comprende una unidad de medición de voltaje (24-27) adaptada para tomar una medición continua de voltaje a través de la válvula electrónica de energía correspondiente, y cada una de las cuatro unidades de puerta (16-19) está adaptada para transmitir su medición continua de voltaje. La unidad de control (28) está adaptada para recibir de cada una de las cuatro unidades de puerta (16-19) su medición continua de voltaje y para determinar el valor de voltaje del capacitor de celda (Udc) con base en al menos una de estas mediciones de voltaje.

    IPC: H02M7/49

    Abstract: An arrangement to determine a cell capacitor voltage value (U dc) of a cell (10") of a multi-cell power converter comprises the cell (10") and a control unit (28). The cell (10") itself comprises four power electronic valves (1-4) interconnected as a full-bridge converter having a first and a second phase leg, where each phase leg comprises a series-connection of two (1, 3; 2, 4) of the four power electronic valves and where the connection point (6; 7) between the two power electronic valves of each phase leg is externally connectable, a cell capacitor (5) being connected in parallel to the first and the second phase legs, and four gate units (16-19), each being connected to a corresponding one of the power electronic valves (1-4) as well as to the control unit (28). Each of the four gate units (16-19) comprises a voltage measurement unit (24-27) adapted to take a continuous voltage measurement across the corresponding power electronic valve, and each of the four gate units (16-19) is adapted to transmit its continuous voltage measurement. The control unit (28) is adapted to receive from each of the four gate units (16-19) its continuous voltage measurement and to determine the cell capacitor voltage value (U dc) based on at least one of these voltage measurements.

    Abstract: An arrangement for exchanging power, in shunt connection, with a three-phase electric power network (2) comprises on one hand for each said phase a reactive impedance element (31, 41, 51) and a Voltage Source Converter (32, 42, 52) connected in series with said element, and on the other a control unit (25) configured to control semiconductor devices of turn-off type of said converter for generating a voltage with a fundamental frequency being equal to the fundamental frequency of the voltage of the respective said phase and by that control a flow of reactive power between said arrangement and the respective phase of said electric power network. Each Voltage Sou rce Converter comprises a series connection of switching cells in the form of so-called H-bridges comprisi ng two switch ing elements connected in parallel and each having at least two semiconductor assemblies connected in series. Each switching cell further comprises at least one energy storing capacitor connected in parallel with said switching elements.
