Outline of Final Research Achievements

The first purpose of this study is to verify the usefulness of the proposed no-insulation coil system using a parallel HTS tape conductor to obtain the high stability and high operational reliability required for the HTS coil system, which is the most important element for the practical application of the aluminum induction heating system using HTS coils. The second purpose of this study is to demonstrate a coil system that can be used in a practical induction heating system using HTS coils. The local normal transition characteristics were investigated experimentally by using small test coils and the experimental results were analytically verified. The practical scale HTS coil system for the aluminum induction heating device was also developed and its performance was evaluated.
