Research and design of multi sets of magnetic switches wound on one magnetic ring: Application of magnetic switch in pulsed power device

A technical scheme which the two sets of windings wound on a magnetic ring composed of two sets of magnetic switches is proposed. And on this basis, a scheme of PFL-MARX (pulse forming line MARX generator) circuit is proposed. In this paper, according to the electromagnetic theory and formula derivation, it can be obtained that the magnetizing inductance, saturated inductance, the time of magnetic saturation from unsaturated to saturated have nothing to do with the current number, that is to say, have nothing to do with the number of symmetrical windings wound on the magnetic ring. The conclusion is verified by simulation in the software environment of Maxwell Ansoft. The simulation results show that the theory deduction is correct. In the PSPICE, the model of the pulse compression circuit and the voltage-multiplying circuit is build, and simulation is carried out. The results demonstrate that the scheme is feasible, and it can also play the effect of voltage-multiplying. The implementation of such a scheme can greatly reduce the volume and weight of the pulsed power device.
