Abstract: One embodiment is a unique Vernier machine comprising a rotor and a stator. The rotor comprises a back portion and a plurality of permanent magnets. 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.
