Abstract :
Many transformers using low Tc or high Tc superconductors have been built and tested, but it is still not clear how to design the volt/turn ratio property. This paper shows one design method, which minimizes total cost including initial cost and running cost. According to the results, the optimized volt/turn will be around 1 volt which is considerably lower than the volt/turn ratio of a conventional transformer of 10 to 20 volts.
