Abstract: A transformer comprising a core and winding wound around a winding axis extending along a limb of the core, said winding terminating in an axial end surface extending in a direction perpendicular to said winding axis, said transformer comprising a ring comprising magnetic material, said ring being located outside said winding and adjacent to said axial end surface. The ring comprises a set of magnetic metal components, such as magnetic metal sheets, said magnetic metal components being distributed about the winding axis and electrically insulated from each other. The core comprises a yoke, said yoke extending radially across the ring, at one or more crossing locations, from a radial inside of the ring to a radial outside of the ring. The cross-sectional height of the ring varies about the winding axis such that magnetic metal components at the crossing locations have lower height along the winding axis than magnetic metal components further away from the crossing locations.

Abstract: A transformer arrangement includes a first and a second arrangement side and a transformer with first windings coupled to the first arrangement side and with second windings having a first to a fourth tap. The transformer arrangement comprises a converter coupling the first, second and third tap to the second arrangement side, a first filter circuit coupling the first tap to the third tap and a second filter circuit coupling the third tap to the second tap.

Abstract: A magnetic core for an electromagnetic induction device, comprising: a limb made of a grain-oriented material, a yoke made of an amorphous material, and an auxiliary joint member made of grain-oriented material, wherein the auxiliary joint member joints the limb with the yoke, wherein the grain orientation of the limb is perpendicular to the grain orientation of the auxiliary joint member.

Abstract: The disclosed techniques can provide users with a tool having an integrated, user-friendly interface and having automated mechanisms which can reveal correlations between data streams to the users in a clear and easily understandable way, thereby enabling the users to easily digest the vast amount of information contained in activities within one or more network, to understand the correlations among the activities, to stay informed and responsive to current or new trends, and even to predict future trends. Among other benefits, the disclosed techniques are especially useful in the context of discovering impacts of social networking activities on other types of commercial activities.
