A method of using saturable pulse transformer (SPT) in series with a magnetic switch is adopted in research on high power pulsed power miniaturisation and high repeat frequency in this study. SPT not only plays a part in boosting, but also plays a part in pulse compression. In this case, a stage magnetic pulse compression can be omitted, and the volume and weight of the system are both reduced. First, the topology of pulse power supply is presented, and working principle of the topology is introduced in detail. At the same time, the dynamic process of de‐magnetic saturation control circuit of magnetic switch is analysed. Second, the selection principle of magnetic core of SPT and magnetic switch is given, and the core used in this study is modelled in PSPICE. At last, the whole circuit is modelled and simulated in PSPICE. Simulation results show that the proposed scheme is feasible, which has a good theoretical guidance for the subsequent experimental work.
