Hysteresis losses in MgB2 superconductors exposed to combinations of low AC and high DC magnetic fields and transport currents

Magnusson, Niklas; Abrahamsen, A.B.; Liu, D; Runde, Magne; Polinder, Henk (Peer reviewed; Journal article, 2014)

MgB2 superconductors are considered for generator field coils for direct drive wind turbine generators. In such coils, the losses generated by AC magnetic fields may generate excessive local heating and add to the thermal ...
