Abstract

Analysis of the electromagnetic processes is organized beside this article in electric circuit
with semiconductor commutator. Mathematical model is created for analysis electro-magnetic processes in
semiconductor converter with width pulsed regulation of the output voltage. The broughted graphs, which
reflect the electromagnetic processes in electric circuit. Method much parametric functions was used when
performing calculation. The mathematical model of the converter is created for twenty zoned regulations of
the output voltage. Article is devoted to the development of a method of multi-parametric modulating functions by means of working out of new mathematical models and definition of functions and the algorithmic
equations for the analysis on sub-system components of electromagnetic processes in electric circuits of variable structure with sinusoidal, direct and pulsing voltage. Introduction of functions with discrete parameters
in the algorithmic equations for analysis of processes in circuits with semiconductor commutators simplifies
modeling on subsystem components. The mathematical model of steady-state processes and transients in
electric circuits of semiconductor converters of modulation type with multi-channel zonal use of phase and
line voltages of a three-phase network of power supplies is developed. The mathematical model of electric
circuits of thyristor shapers of electro-discharge pulses for the analysis and the matching of capacitors
charging modes with decrease several times of electric resistance of technological load is also created. The
obtained results have a great value for development theoretical electrical engineering in a direction of simplification of calculations of electromagnetic processes in electric circuits with semi-conductor converters of
the electric power. The Electromagnetic processes in electric circuit under width-pulse regulation possible
to analyse with use the algorithmic equations multivariable function, which argument are a system parameters semiconductor commutator, signal of control, phases to network of the power supply and time. Introduction multivariable function with discrete parameter in algorithmic equations of the analysis formed and connecting processes in electric circuit of the variable structure allows to reflect change of this structure under
system components, simplifying modeling and analysis of such processes to account of the generalization of
the got equations. Except specified correlations and diagrams designed model allows to analyse forms of the
output voltages and current of the separate power modules.
