Abstract
The electromagnetic characteristics and iron loss of a high-temperature superconductor wind generator (HWG) equipped with an overlapped field coil arrangement (OFCA) are studied by comparing with the one equipped with the conventional field coil arrangement (CFCA). Through a quantitative analysis, it was found that HWG with OFCA exhibits better electromagnetic characteristics than HWG with CFCA and can reduce the iron loss by eliminating the magnetic flux sag caused by the adjacent field coil sides with the same current flow direction. In addition, the OFCA topology can further reduce the volume of the wind generator.
