摘要

The main development trends of pulsed power supply are miniaturization, lightweight and repetition rate. High temperature superconducting (HTS) inductive pulsed power supply has stimulated enormous research interest of researchers because of its high energy storage density, low loss and low power requirements. High temperature superconducting pulse transformer (HTSPPT) is an important device for the HTS inductive pulsed power supply. It is usually used for energy storage and pulse compression. Aiming at the development of pulsed power supply, we proposed a pulsed power supply circuit topology for continuous current pulse operation based on HTSPPT. The working process and the critical parameters were analyzed. A 3 kJ HTSPPT coil module was constructed by using the finite element simulation, and the critical parameters calculation method was verified. The simulation and theoretical results show that although the current amplification factor decreases with the increase of the secondary inductor, the maximum voltage of the opening switch and the maximum capacitive energy storage ratio are also decreased. Finally, the experimental circuit of this continuous pulsed power supply is built by using a small HTSPPT, and the output of continuous current pulse is realized. The feasibility of this continuous pulsed power supply circuit can be proved by simulation and experiment results.
