Abstract

High temperature superconductor (HTS) techniques can be used to design high efficiency power or traction transformers with considerable AC loss and volume reduction compared with conventional transformers. Further, HTS transformers are environmental friendly, with no risk of fire hazard or pollution. In this paper, superconductor windings of a transformer are modeled and flux diverters (FDs) are applied to the ends of windings for magnetic field and AC loss analysis. A homogenization approach is used to save computation cost of the model. The distribution of AC loss is quantized for analysis. Observations suggest that the flux diverters optimize flux distribution and are conducive to AC loss reduction.
