| Outline of Final Research Achievements |
High temperature superconducting wires have generally critical current of over 200 A and therefore power supplies which can output large AC current are needed for measuring current conduction characteristics of the wires. However, commercial AC power supplies are generally very large and heavy, and are difficult to handle in ordinary laboratories. In this study, the authors developed a small and light AC power supply with a high temperature superconducting transformer. The power supply can output AC current of 1 kA and its size and weight are 1/25 of a commercial power supply.
