Effect of magnetizing inductance on pulse waveform drop of linear transformer driver

Based on the experimental device of the linear transformer driver, the effect of magnetizing inductance on the pulse waveform drop is theoretically and simulatively studied in this paper. The formulae are deduced, with which the effect of magnetizing inductance is calculated. In addition, the output pulse waveform is simulated through the Pspice software. The theoretical and simulated results agree well with each other, which show that the waveform drop is more obvious with the smaller magnetizing inductance. In order to reduce the waveform drop, we have designed an apparatus which can offer direct current of 50 A for bias magnetization， with which the LTD can steadily obtain output pulse with rise time of 35 ns, voltage of 125 kV, pulse duration of 130 ns and little waveform drop (less t
