Arrangement Optimization of the Superconducting Pulsed Power Transformer of Inductive Pulsed Power Supply

High-temperature superconducting pulsed power transformer (HTSPPT) is an important component of superconducting pulsed power supply. Six superconducting coils and four normal conducting coils have been designed and manufactured in our previous work. The six superconducting coils and four normal conducting coils can be assembled into a large HTSPPT to obtain high energy storage. Five arrangement modes are proposed and analyzed in this paper. The self-inductance, coupling coefficient, magnetic field distribution and critical current of the five modes are obtained by finite-element simulation and calculation. The results show that Modes 1, 2, and 4 are feasible. Especially, Mode 1 has the highest coupling coefficient, the largest critical current, the highest energy storage capacity, the lowest capacitor voltage, and the shortest current rise time. As a result, Mode 1 is the best assembly sequence for the HTSPPT. The alternate arrangement of all primary and secondary coils can obtain the highest coupling coefficient and energy storage capacity.
