Study on AC Loss of HTSPPT under Continuous Pulse Power Supply

The AC losses of high-temperature superconducting pulse transformers (HTSPPT) can directly affect the miniaturization and lightweight of pulse power supplies. In this paper, a simulation of the HTSPPT using the H-equation method is performed to investigate the AC losses and electromagnetic characteristics of the HTSPPT during the charging and discharging process of the continuous pulse power supply. The effect of primary and secondary winding coupling on the AC loss of the pie-type coil stack structure is investigated. The results show that the magnetic field distribution changes, and the AC losses are reduced after the primary and secondary windings are coupled in a pie-stacked structure.
