ABSTRACT:
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.
