    Abstract: An arrangement to determine a cell capacitor voltage value (Udc) 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 (Udc) based on at least one of these voltage measurements.

    Abstract: A multilevel converter and a method for controlling a multilevel converter is provided. The multilevel converter is a single phase converter with one phase leg (1), or a three phase converter with three phase legs (1A-C), the phase legs of the three phase converter are interconnected in a star-configuration. The (1), or each (1A-C), phase leg comprises switching cells (11, 21),and each switching cell (11, 21) comprises semi-conductor switches (41, 51) arranged to selectively provide a connection to a corresponding energy storage element (42, 52). The converter also includes a controller (31), which is provided to monitor the DC voltage (VDC) of the energy storage elements (42, 52), and the controller (31) is provided to control the switching of each switching cell (11, 21). The phase leg (1) of the single phase converter, or each phase leg (1A-C) of the three phase converter, comprises two parallel branches (10, 20) of switching cells (11, 21), the branches (10, 20) being configured in a closed circuit. The method includes monitoring (105) the voltage levels of each of the energy storage elements, and balancing (107) the voltages of the energy storage elements, wherein the balancing includes circulating a current (104, 107) within the two branches of the (1), or each (1A-C), phase leg of the multilevel converter.

    Abstract: The invention relates to a method and a controller (8) for protection of a voltage source converter (1) comprising one or more phases (L1, L2, L3), each phase comprising one or more series- connected converter cells (2-1L1, 2-2L1,..., 2-nL1; 3-1L2, 3-2L2,..., 3-nL2 : 4-1L3, 4-2L3,..., 4-nL3). Each converter cell comprises a by-pass switch (S-1L1, S-2L1,..., S-nL1; S-1L2, S-2L2,..., S-nL2; S-1L3, S-2L3,..., S-nL3) for enabling by-pass thereof. The method comprises the steps of: detecting an over-voltage condition, and controlling simultaneously the by-pass switches of each converter cell so as to bypass the converter cells upon detection of such over- voltage condition.
