Reduced Ac Loss High Temperature Coated Conductor

Abstract
Los Alamos National Laboratory has developed a technique to reduce hysteresis losses in high temperature superconducting coated conductors due to ac transport currents and/or magnetic fields. This technique is achieved without significantly changing the geometry of YBCO coated conductors.

Application(s)
Power cables
Magnetics
Electric motors
Current limiters
Other power engineering equipment

Advantages
� Reduces heat within the superconductor � Increases the viability of superconductors in power engineering equipment and applications � Increased overall efficiency of the conductor
