The zero resistance of superconducting material is observed only with a DC current, while transmission loss occurs with an AC current. Power converters use electronic devices which generate harmonic currents due to their high switching frequency. The authors expect that harmonic currents also influence the losses in the superconducting DC power cables of a DC transmission system. The authors have developed a miniaturized superconducting DC transmission system with 12 thyristors based AC/DC converter and a 2 m length superconducting cable connected to the DC side between two converters. The capacity of the converter is 20 kW and the critical current of the HTS DC power cable is 140 A. In this paper, the HTS DC power cable loss characteristics were analysed by the fabricated home-made thyristor converter system.
