Design and Performance Analysis of an Iron Core-based No-Insulation HTS Magnet for HTS DC Induction Heating Machine

Publication date: 2016 Source:Physics Procedia, Volume 81 Author(s): Jongho Choi, Kwangmin Kim, Sung-Kyu Kim, Seokho Kim, Kideok Sim, Minwon Park, In-Keun Yu An energy efficiency of a high temperature superconducting (HTS) DC induction heating machine is improved up to 80∼90%. The core technology in the machine is to ensure its thermal stability during operation. In this paper, we presented design details and performance analysis results of no insulation HTS magnet with an iron core for an HTS DC induction heating machine. The HTS magnet was simulated by a finite element method and an equivalent circuit analysis. In order to confirm physical performances, the magnet was fabricated and experimented with an iron core as well as without an iron core. The simulated and experimented results were analyzed in detail.
