Abstract :
Ultra-high efficiency (>99%) power conversion and the corresponding energy savings can be accomplished by combining two new devices: the cryogenic power MOSFET and the high current inductor made with high-temperature (HT) superconductors. Their properties are reviewed. Several possible applications are discussed such as high-power inverters, switchmode amplifiers, and multi-kilowatt RF generators. Design information is presented for the thermal losses of a cryogenic container and the required electrical conductors to a cryogenic circuit. It is investigated if there are potential advantages of cryogenic power conversion such as drastic size, weight, and cost reductions at improved reliability
