A Multi-Module HTS Inductive Pulse Power Supply With Wide Current Pulse Output

High-temperature superconducting (HTS) inductors have the advantages of low loss, low charging power, and long-term energy storage, making them very suitable for high-power inductive pulse power supplies (IPPS) for continuous electromagnetic launch (EML). However, driving the rail type EML requires high amplitude and a certain pulse width of the current pulse. The current inductive pulse power supply modes are difficult to meet this requirement. For this issue, this paper proposes a new multi-module IPPS circuit based on high-temperature superconducting pulse power transformers (HTSPPT). The proposed pulse power supply consists of three groups of HTSPPTs, each group consisting of 12 HTSPPTs forming a circular structure. By delaying parallel discharge of three sets of HTSPPT modules, high amplitude and wide pulse width current pulses can be generated. The feasibility of this power supply mode was preliminarily verified through simulation in the paper.
