    摘要： A hybrid circuit breaker for interrupting fault currents comprises a mechanical switch (31) through which a normal current is passed, the mechanical switch being arranged to open in case of being exposed to a fault current; and a semiconductor breaker device (32) to which the fault current is commutated, the semiconductor breaker device being arranged to break the fault current. The mechanical switch has a contact arm (33) with two contacts (33a-b) abutting stationary contacts (34a-b) of a circuit when being closed, wherein the two contacts of the contact arm are located at different distances (x1, x2) from the axis of rotation such that the separations (z1, z2) between the two contacts of the contact arm and the two stationary contacts are different when the mechanical switch opens. The semiconductor breaker device is connected in parallel with the contact (33b) of the contact arm and the stationary contact (34b) which separate most when the mechanical switch opens.

    摘要： An electric plant with a capacity to charge electric batteries is a plant for transmitting electric power comprising a Voltage Source Converter (1), an alternating voltage network (14) connecting an alternating voltage side of the converter and a direct voltage part (7) connected to the direct voltage side of the converter. The converter (1) has a series connection of switching cells (8) having each at least one energy storing capacitor. Electric batteries may be connected in parallel with said capacitor, and the charging state thereof may be influenced by controlling the switching cells of the Voltage Source Converter through a control arrangement (15).

    摘要： A power module (10), which is operated serially with other similar power modules in a converter valve, comprises a plurality of submodules (13a-d) connected in parallel, wherein each of the submodules includes one or several semiconductor elements connected in parallel and the power module is of the kind wherein if one of the submodules starts malfunctioning, the remaining ones of the submodules assume a closed circuit. The power module further comprises, for each of the submodules, a separate driver unit (14a-d) for driving the one or several semiconductor elements of that submodule, and a separate control unit (11a-d) for controlling the driver unit of that submodule. The power module may be used in HVDC or SVC apparatuses.
