Modeling the generator of electro-pulse discharges

Abstract

The article discusses some aspects of modeling the dynamics of high-gradient pulse processes accompanying technologies using electrical discharges in a liquid medium. Due to the presence of high pressure, these technologies are successfully used for the destruction and crushing of solid materials, the processing of mineral environments, the intensification of heat exchange processes, etc. The development of a pulse signal generator with a given frequency, taking into account the influence of environmental parameters, is an urgent technical problem. The main element of electric pulse technology is a generator for providing high discharge energy at a given frequency. A brief analysis of the block diagram of an RLC generator with pulse parameters is given. The possibility of a description of an RC generator of pulsed electric-discharge oscillations based on a system of dynamic equations is shown. Numerical solutions to the dynamic equations of the model oscillator using the MatLab package are presented, and phase portraits for various parameters are shown. The graphs of numerical calculations are in qualitative agreement with the oscillograms of pulsed current and voltage and reflect the nature of the dynamic patterns. The results obtained can be used in practice to select parameters that ensure a given operating mode of electric discharge equipment.
