High temperature superconducting pulse transformer （HTSPPT） which can be used for energy storage and pulse amplification is an important device for some inductive pulsed power supplies. In order to reasonably design geometry parameters of HTSPPT coils to meet the trends of miniaturization and high energy density of the pulsed power system. In this paper, the coaxial pancake coil structure was selected as the model of the superconducting pulsed power transformer. The influences of superconducting coilg geometry parameters on the critical current density, the energy storage, the hoop stress and the coupling coefficient of the pulsed power transformer were analyzed by finite element simulation software Ansoft Maxwell. According to the simulated results, when the height - thickness ratio of primary HTS coil is less than 0.3, the small HTSPPT can obtain better performance. The results provide a theoretical basis for the basic experimental research on inductive pulsed power supply.
