Magnetic Pulse Compression in Power Supplies of Radiation Generator Devices

High power pulses with low widths have many applications in radiation generator devices as flash radiography and high power microwave generators. One of the compression methods of high power pulses is magnetic pulse compression. In this paper a Tesla generator with saturated core which produces a 200kV voltage pulse has been designed and then the effect of saturation of the core in the compression of the output pulse using Proteus and CST EM Studio codes was studied. Our studies showed that with saturation of the transformer’s core, the magnetic permeability and hence the inductance of the transformer’s coils will decrease and consequently the frequency of current oscillations in the transformer will momentarily increase where it will result in the decrease of the output pulse width.
