    摘要: Provided is an insulated oxide superconducting cable conductor having a high critical current and a high critical current density. The insulated oxide superconducting cable conductor comprises an elongated former, a plurality of tape-shaped multifilamentary oxide superconducting wires which are wound on the former at a bending strain factor of not more than 0.5%, and a spirally wound tape-shaped insulating material covering the tape-shaped multifilamentary oxide superconducting wires. The tape-shaped multifilamentary superconducting wires are superposed on the former in layers, whereby stabilizing materials of the superposed superconducting wires are in contact with each other. The tape-shaped insulating material consists essentially of a material which is contracted at a thermal contraction rate of at least three times that of the tape-shaped multifilamentary wires by cooling from a temperature of 298 K to that of 77 K. The tape-shaped insulating material can apply a pressure to the superposed multifilamentary superconducting wires toward the former while improving electrical contact between the superposed multifilamentary superconducting wires by cooling in employment. The former can be formed of a flexible tube.

    摘要: A DC power supply apparatus includes an input-side rectifier which rectifies an input AC voltage and supplies the rectified voltage to a voltage-boosting converter. The voltage-boosting converter converts the supplied voltage to a voltage of a predetermined magnitude. The predetermined magnitude voltage is, then, converted to a high-frequency voltage by an inverter and applied to a primary winding of a transformer. An output-side rectifier rectifies a high-frequency voltage induced in a secondary winding of the transformer. The inverter includes IGBTs and diodes, which are connected in a full-bridge configuration. A capacitor is connected in parallel with each IGBT. When the IGBTs are rendered conductive by the charging and discharging of the capacitors, no current flows through the IGBTs, and when the IGBTs are rendered nonconductive, the voltages applied to the IGBTs are made to become zero.

    摘要: A method can include obtaining a voltage across a first transistor as an obtained voltage. The method can also include multiplying the obtained voltage by a predetermined multiple M to yield a multiplied voltage.
