Abstract

The numerical simulation of electromagnetic processes in magnetic semiconductor generator of high-voltage pulses with series-parallel conversion unit in the input circuit is conducted. Electrical and magnetic characteristics of the compression units for the symmetric regime of oscillations of the generator are given and describes a process that leads to increased the voltage across the longitudinal capacitor of parallel conversion unit. Electric and power characteristics of the generator in dependence on the input voltage and the equivalent load resistance are shown. It is shown that a family of characteristics of the peak values of voltage and current through the transducer element and the stored energy in the longitudinal capacitor have a similar character and are described by a nonlinear increasing dependence. The input voltage limits of the magnetic pulse generator which achieve the highest efficiency of the conversion unit are defined. It is shown that the linearity characteristics of conversion unit in the appropriate range of load resistances at a definite value of the input voltage, is explained by agreed energy transfer from a capacitor parallel conversion unit in the high voltage capacitor.
