Marx Generator Model for Corona Discharge in Air

To calculate the parameters of the Marx generator, such as the voltage at the generator output, the values of the circuit elements and, if necessary, the number of generator cascades, an electrical model was created with a load represented as a negative corona discharge in a cylindrical electrode system at atmospheric pressure. When creating the model, its input parameters were defined, the influence of the current-voltage characteristic of the corona discharge on the generator operation was investigated, and the impact of deionization processes on the output parameters of the model (output voltage on the generator, nominal values of circuit elements, etc.) was analyzed. For more effective modeling of processes in the Marx generator, its general equivalent circuit was divided into two parts, in which the charging and discharging processes of the Marx generator stages were studied separately. The model will be useful in the design of relatively simple systems based on a Marx generator that use a corona discharge, such as ionisers, electric filters, surface modification devices, etc.
