[HERKERT, Werner, HUSSENNETHER, Volker] Wittelsbacherplatz 2 80333 München;Görlitzerstr. 11 91058 Erlangen;Heuchlinger Strasse 6 90482 Nürnberg The superconducting winding (2) is configured such that it has a band-shaped HTS conductor (4) of the Röbel-conductor type, made of band-shaped HTS individual conductors that are transposed among each other. An armoring band (5) is to be wound to the prefabricated HTS conductor (4), the band not being metallurgically connected to the HTS conductor (4) and being subject to a comparatively larger winding tension (WZ2). The armoring band (5) is wound at a winding tension (WZ2) that is at least 1.5 times, preferably at least 3 times as large as the winding tension (WZ1) of the HTS conductor (4).

Said inductor contains a ferromagnetic body (3) that conducts a magnetic flux and consists of at least one central core limb (4), two lateral magnetic return limbs (5, 6) running parallel to the central limb and two yoke limbs (7, 8) that magnetically bridge the core limb and the magnetic return limbs. The core limb (4) is surrounded by an HTS winding (9) to be cooled, the current supply lines (10, 11) of said winding penetrating one of the yoke limbs (7) in the vicinity of the cross-sectional area (F) of the adjacent winding (9). The end faces (9a, 9a') of the winding (9) extend almost as far as the respective yoke limb (7, 8).

[Christoph Armschat, Mike Dommaschk, Volker Hussennether, Thomas Westerweller] DE Erlangen A device for inverting an electric parameter in the field of power transmission and distribution has a converter that can be connected between an alternating current grid and a DC circuit and having power semiconductor valves extending between an alternating current connection and a DC voltage connection. Each power semiconductor valve has a series circuit of bipolar submodules, each with an energy storage device and a power semiconductor circuit in parallel with the energy storage device, and a grid connection unit connected to the alternating current connection for connecting to the alternating current grid. Simple, effective, and inexpensive symmetrization of the voltages in the DC voltage circuit relative to ground potential is brought about. A star point reactor is connected between the grid connection unit and the inverter with a potential node, including throttle coils connected to a grounded star point. The throttle coils are implemented so that said coils implement a current path with a high impedance to ground potential for alternating current at the base frequency of the alternating current grid, and with low impedance to ground potential for DC current.
