摘要： A superconducting transformer may include two pairs of axially extending windings. The windings are each in the form of a right cylindrical solenoid having a circular cross-section which are substantially concentrically nested. Each winding includes a plurality of turns formed from superconducting tape. Each winding respectively includes a first end and a second end which are configured for electrical connection with at least one of the other ends, an alternating power source, a load, or other passive or active electrical components. The transformer includes a first axially extending primary winding corresponding to the outermost winding and a first axially extending secondary winding nested within the first primary winding. A second axially extending primary winding is nested within the first secondary winding. A second axially extending secondary winding is nested within the second primary winding such that the second secondary winding corresponds to the innermost winding. The transformer further includes three predetermined gaps which define the radial separation of the nested windings. A predetermined core gap defines the diameter of the second secondary, or innermost, winding.

摘要： An output voltage rising slope control technique for a power converter is addressed. The output voltage rising slope control technique according to the present invention basically uses a reference voltage generator to precipitate the rising slopes of multiple output voltages of a power converter to become mutually unanimous with each other during start-up period, and thereby avoid the occurrence of system faults in the power converter due to the instantaneously rapid increase of output voltage thereof during start-up period.

摘要： The invention relates to a circuit configuration for monitoring and/or for regulating supply voltages. Said circuit enables at least two supply voltages (U12) or (U22) that are produced by means of two feed-ins (Q1, Q2) and that are provided for consumer circuits (V1, V2) to be monitored and limited simultaneously. To this end, the circuit configuration comprises a corresponding voltage monitoring electronics unit (1) which detects the supply voltages (U12, U22) and compares them with associated tolerance values (nullU12, nullU22). The voltage monitoring electronics unit (1) also provides a control signal (y) which signals whether the first supply voltage (U12) is lower than the associated tolerance value (nullU12). The control signal (y) is used to control a shunt electronics unit (2) through which a shunt current (IS) passes temporarily. Said shunt current (IS) is fed by feed-in (Q1) and by feed-in (Q2) and passes through the shunt electronics unit (2) at least when the control signal (y) signals that at least the supply voltage (U12) is greater than the associated tolerance value (nullU12).
