AC APPLICTIONS

• Superconductors have losses due to
• Hysteresis
• Coupling currents
• Losses are dependent on (in magnetic fields above
  50mT)
• External magnetic field ( B²)
• Current ( I²)
• Frequency ( f)
• The Superconductor becomes a conductor with very
  low resistance
• Factors are
• Field B
• Operating Current I
• Frequency f
• Combination of losses, operating temperature,
  overall efficiency and external factors (e.g.
  size requirement) determine economic feasibility
