  • Abstract
    We have been developing superconducting transformer for high speed train. Its objects are reducing the weight and energy consumption. We have developed 4MVA class superconducting transformer in 2004. After that, we have improved the efficiency from 96% to 98%. We also have developed 1kW prototype lightweight refrigerator which is essential to realize superconducting transformer.
