Abstract
Dependence of values of large-scale current fluctuations in turbulence-type plasmatrons upon the power circuit parameters has been studies by the method of a calculation experiment. As shown by its results, the value of the arc current fluctuations first decreases with increase in the natural frequency of the power circuit, and then remains approximately at a constant level that lowers with increase in circuit inductance.
