Description: Analysis of the electromagnetic processes is organized In article in electric circuit with semiconductor commutator. Mathematical model is Created for analysis of the electromagnetic processes in semiconductor converter with width-pulse regulation of the output voltage. It Is Shown graphs that display the electromagnetic processes in electric circuit. It Is Designed new mathematical model formed and connecting processes in electric circuit of the semiconductor converters inflexion type with many-server zoned use the linear voltages three phases to network of the power supply disregarding losses to electric powers in commutator for quick estimation of the influence parameter loads on features controlled sine and constant voltages. The Results of this work possible to use for development of the method multivariable modulating function for simplification of the analysis of the connecting processes in electric circuit disregarding losses in key element.
Keywords: electromagnetic processes, output voltage and current, current of the load, method multivariable modulating function
