摘要： A method and apparatus for powering a high power load (on the order of 50,000 watts or more) can have an input from any of a plurality of different voltage sources, AC or DC. In one embodiment, the AC sources can have a frequency in the range of 162/3-60 Hertz, and voltages in the range of 480-38,000 volts. The method and apparatus feature cryocooling inverter electronics, which converts an input signal to a high frequency high voltage signal, to, for example, less than about 180K. A high frequency transformer receives the high frequency high voltage signal and transforms it into a desired voltage level which can then be filtered and/or demodulated and applied to the load. The transformer is preferably comprised of a superconducting material, and then, the inverter and transformer, at least, are actively cooled as required. In a particular embodiment, the circuitry replaces the heavy transformer construction used in driving induction motors in an electric traction engine from an overhead line or a third rail. This system can also employ an interlink between the rectified DC and the inverter for energy storage and smoothing effects.

摘要： A cryogenically cooled circuit, operating at temperatures at which inductors windings of the circuit exhibit superconducting characteristics, provides unique advantages in high performance, preferably high power circuits. Portions of the circuit (or the entire circuit), as opposed to, for example only the superconducting elements (i.e., inductor winding), are refrigerated to cryogenic temperatures. Advantages in the characteristics of not only the superconducting based components but also the diodes, and gating elements such as MOSFET's, yield a uniquely advantageous circuit enabling the operation of, for example, a switching power supplies, frequency converters, and motor speed controllers with increased performance and efficiency. Size, component count, and stability are benefits attained by cryogenically cooling the entire circuit configuration. Cryogenically-cooled solid-state contacting switches may be utilized for connecting/disconnecting AC and/or DC power between the high performance circuit and a source/load.

摘要： A superconducting transformer comprises primary and secondary superconducting coils which are coaxial and made of superconducting wires, and a cryostat for maintaining the superconducting coils in a superconducting state. The cryostat includes a vessel for containing refrigerant and which is formed of a ferromagnetic material. The coils are immersed in the refrigerant. Rod formed of ferromagnetic materials is inserted in the primary and secondary superconducting coils, and is magnetically coupled with the vessel. The cryostat also includes a heat insulating tank for thermally insulating the rod and the vessel from the refrigerant. The rod and the vessel together form a closed magnetic circuit, and function as a core for the superconducting coils.
