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
