Abstract: An electrical system forming part of a solar power plant is described. The electrical system includes a plurality of photovoltaic (PV) panels, a power converter, and a controller. In response to a detected electric arc on the DC side of the power converter, the controller is configured to enable a short circuit state of the power converter by controlling semiconductor switches of the power converter (e.g., turning on some or all of the semiconductor switches) to create a short circuit between DC input terminals of the power converter. The short circuit path though the power converter will extinguish the detected electric arc in the connected DC circuit.

Abstract: A stator for an electrical machine is described. The stator includes a plurality of axially adjacent generally annular laminations. An axially extending coolant passageway through which a coolant fluid flows in use, extends through the stator. A plurality of axially spaced sealing recesses are provided. Each sealing recess is located between a pair of laminations and is in open communication with the surface of the axially extending coolant passageway. Each sealing recess has an axial width greater than the gap between the facing planar surfaces of axially adjacent laminations and is at least partially filled with a cured resin material to define a plurality of axially spaced seals.

Abstract: The invention relates to a cover to enclose a longitudinal section of at least one electrical conductor and prevent the formation of an arc or a flashover. The cover has at least two cover parts made of an electrically insulating material. A first cover part and a second cover part each have at least one passage opening. Each passage opening has an electrical conductor guided through it, so that no gap opening, or only a small gap opening remains between the outside surface of the conductor and a bordering wall of the passage opening. Moreover, the cover has at least one connection location. At this connection location, two of the cover parts that are present lie against one another in a force-fit and/or positive-fit manner and form a nondestructively detachable connection. This ensures accessibility to the protected longitudinal section.

Abstract: The drive unit is designed to be mounted on a marine vessel, including a mobile housing, and is able to pivot around an axis against the hull of the marine vessel. A drive shaft mounted rotary is against the mobile housing and is supported by two roller bearings. A propulsion element rotates in solidarity with the drive shaft. The propulsion unit has, at the front, at least two braking and locking systems of the drive shaft located in an area between the upstream rolling bearing and propulsion element.

Abstract: An inverter and method of controlling an inverter, which is connected between a photovoltaic generator and a power supply network for ride-through of a network fault, is disclosed. A voltage dip is detected in the network voltage and the voltage of a DC voltage link of the inverter is monitored. When the DC link voltage exceeds an upper limit value, an operating mode for ride-through of the network fault is started. The upper limit value corresponds to a saturation voltage in the specific Iac/Udc characteristic curve of the inverter, above which the maximum AC output current of the inverter decreases. In the FRT operating mode, an energy dissipation device dissipates power from the DC voltage link and is controlled to keep the DC link voltage within a range below the saturation voltage.

Abstract: A dual submodule is created for a modular multilevel converter, whereby the dual submodule has two interconnected submodules, whereby each submodule has an asymmetrical half-bridge circuit with two parallel bridge branches, which are connected between a first and a second terminal connection of the submodule, whereby each bridge branch is formed from a series circuit of a power semiconductor switch, and a diode, whereby the power semiconductor switch is allocated to an antiparallel free-wheeling diode, and has a capacitor, which is connected in parallel with the asymmetrical half-bridge circuit between the first and the second terminal connections of the module. The submodules are connected to each other via their AC terminals to form the dual submodule. Further, a modular multilevel converter is created, comprising a number of such dual submodules in each of its converter branches.
