AC applications of HTS wires and coils

This presentation/paper gives an overview of the Oak Ridge National Lab`s collaboration with private industry in developing AC applications for High-Temperature Superconductor (HTS) wires and coils. Highlighted is the lab`s general approach and technical progress towards: design and fabrication of HTS magnet; stability and normal zone propagation performed on conductors and magnets; design for the optimum inductor for use in a current-fed inverter; and AC coil losses on HTS coils wound with twisted filaments. The projects are in collaboration with American Superconductor Corporation and included are the proposed projects for FY 1995, key personnel, and the fiscal 1994 budgets.
