The stator comprises a plurality of ferromagnetic arm structures, a plurality of ferromagnetic pole structures extending from each of the ferromagnetic arm structures in a direction toward the permanent magnets, and a plurality of conductive windings disposed about respective ones of the plurality of ferromagnetic arm structures. The ferromagnetic pole structures are structured to collect magnetic flux from the permanent magnets. The ferromagnetic pole structures of each of said ferromagnetic arm structures are spaced apart from one another according to a non-uniform pattern such that the ferromagnetic pole structures of a given ferromagnetic arm structure have substantially the same angular position relative to the permanent magnets radially opposite from the ferromagnetic pole structures of the given ferromagnetic arm structure.

Abstract: An IGBT is provided having a first gate unit having first trench gates with first conductive layers and planar gates with second conductive layers. A second gate unit having a second trench gates may be connected to the emitter electrode, with the first and second conductive layers forming a first shape closed in itself and enclosing the second gate unit. Third trench gates are arranged between a planar gate and the second gate unit such that first and third trench gates are connected and form a second shape closed in itself by which the second gate unit is enclosed. P+ doped bars below the planar gale contact the emitter electrode with each third trench gate separating a bar and a planar gate electrode from the second gate unit, with a p doped base layer separating the second gate unit from the enclosing second shape.

Abstract: A method for controlling an electrical converter comprises the acts of determining an error value based on a difference between an estimated output value and a reference output value, the estimated output value being based on measurements in the electrical converter; comparing the error value with an error band and in the case of the error value exceeds the error band, controlling the electrical converter by switching to a different control scheme. The converter is controlled with the modified pre-calculated switching by determining a pre-calculated switching sequence for the converter based on an actual state of the electrical converter, the switching sequence comprising a sequence of switching transitions of the converter; modifying the pre-calculated switching sequence by modifying transition times of switching transitions of the pre-calculated switching sequence, such that the error value is minimized; and applying at least a part of the modified switching sequence to the electrical converter.

Abstract: A testing container includes a right-parallelepiped-like container, electrical components of a transformer test system which are arranged in the container and which represent a respective heat source during a testing operation, and a cooling system including at least one heat exchanger. In addition, the testing container includes a movement apparatus configured to move the at least one heat exchanger from a transport position within the container into a working position which is located at least partially outside the container. Thus, the at least one heat exchanger is movable by means of the movement apparatus from the transport position within the container into the working position which is located at least partially outside the container.

Abstract: An assembly includes a cabinet having an interior and a door to gain access to the interior. An intelligent electronic device (IED) is within the interior of the cabinet and includes inputs providing electrical connections to the IED, pushbuttons to provide user input to the IED, a display module including a display, a component, and a timer circuit. The timer circuit powers the component OFF or places it in a reduced power state when not in use after a certain amount of time. A switch is associated with the door and is electrically connected to at least one of the inputs so that when the display module is powered OFF or in the reduced power state and when the door is opened, the switch causes a signal to be sent to the timer circuit to cause the timer circuit to power the component fully ON.

Abstract: According to one aspect of the teachings herein, various feeder connection arrangements and architectures are disclosed, for collecting electricity from wind turbines in an offshore collection grid that operates at a fixed low frequency, e.g., at one third of the targeted utility grid frequency. Embodiments herein detail various feeder arrangements, such as the use of parallel feeder connections and cluster-based feeder arrangements where a centralized substation includes a common step-up transformer for outputting electricity at a stepped-up voltage, for low-frequency transmission to onshore equipment. Further aspects relate to advantageous generation arrangements, e.g., tower-based arrangements, for converting wind power into electrical power using, for example, medium-speed or high-speed gearboxes driving generators having a rated electrical frequency for full-power output in a range from about 50 Hz to about 150 Hz, with subsequent conversion to the fixed low frequency for off-shore collection.
