The simulation and analysis of steady-state and transient processes in three-phase electrical circuits with semiconductor converters using nine-zone voltage regulation on the electro-technological load in the form of active- inductive resistance is carried out. The simulation was carried out using the method of multivariable functions, which made it possible to simplify the view of algorithmic equations for the analysis of electromagnetic processes in converters whose electrical circuits can contain more than two independent reactive elements. Without taking into account the power losses in semiconductor switches of the converters, the features of using the phase voltages of the power supply network to realize the nine-zone regulation of their output voltage are shown. The graphs reflecting the features of regulation of this voltage on the electrotechnological load are given. References 10, figures 3.
Key words: output voltage and current, method multivariable modulating function.
