    Abstract: The invention concerns a DC/DC converter (10) comprising a first conversion branch stretching between a first and a second DC terminal (18, 20), a first controllable voltage source (UbIp) in a first half of the first conversion branch, a second controllable voltage source (UbIn) in a second half of the first conversion branch, a conversion unit (14A) converting between AC and DC and at one end connected to a third and a fourth DC terminal (22, 24), and a transformer (16) with a primary winding connected in a first interconnecting branch stretching between a first junction at which the first and second controllable voltage sources are connected to each other and a first potential that lies in the middle between the potentials of the first and second DC terminal, and a secondary winding connected to another end of the conversion unit.

    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: A DC-DC converter (200) comprising a first (201) and a second (202) variable voltage source, a capacitor (203), an alternating current filter (204), and controlling means (205), is provided. A first DC voltage (UDC1) is provided over a series-connection of the first and the second voltage source, and a second DC voltage (UDC2), being lower in magnitude than (UDC1), is provided over the second voltage source. The conversion between (UDC1) and (UDC2) is effected by circulating an alternating current within a circuit comprising the two voltage sources and the capacitor, thereby exchanging power between the two voltage sources. The alternating current is driven by AC voltage components provided by the first and the second voltage source. The controlling means is arranged for controlling the first and the second voltage source so as to maintain a phase difference between the AC components to be close to π.
