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.
