Review of high power density superconducting generators: Present state and prospects for incorporating YBCO windings

This work focuses on the development of high power density generators for airborne applications by bridging the chasm between generator and high temperature superconducting (HTS) wire developmental efforts. Benefits of HTS power generation include improved efficiency, thermal management reduction, improved power handling, reduced life cycle costs, and size and weight reduction. Superconducting generator development from the 1970s is outlined, and the basic types of ac synchronous generators are described. The benefits of HTS conductors in general and HTS coated conductors in particular are discussed. Critical issues for the employment of HTS coated conductors are then considered and recommendations made for enhancements to the HTS coated conductor for implementation in the more advanced superconducting power generators.
