Efficiency Analysis of a High-temperature Superconducting Induction Heater
نویسندگان
چکیده
In an induction heater for heating of aluminum billets, the main reason for using high-temperature superconducting (HTS) tapes instead of conventional copper conductors is to reduce the large power losses in the induction coil. In this work we present how to calculate the different loss contributions of an induction heater based on HTS tapes. Calculations of these losses are used in the design of an HTS induction heater with a rated power of about 10 kW operating at liquid nitrogen temperature. The calculations predict an optimal current that yields the highest efficiency of the induction heater.

Induction heating of aluminium billets using superconducting coils
It is proposed to apply high-temperature superconducting (HTS) tape in the coil windings for induction heaters for aluminium or copper extrusion billets. The potential for efficiency improvements is substantial, as conventional copper coil induction heaters rated for up to around 1 MW operate with an overall efficiency of typically only 50–60%. The efficiency of a HTS induction heater depends v...
