Transient Processes in the Electric Circuit Where Inverter Arbitrarily Supplies the One-Phase R(L) Loading

This study discusses the transient process formed by universal bridge-IGBT inverter for load supplying: asynchronous engine or the transformer with its R(L) parameters. According to chosen inverter parameters which works in parallel with inductive-capacitance converter and load, formulas are given for voltages and electricity in the circuit, as well as tables which presents the relation of these values. Through simulations in the program package of MATLAB, diagrams appeared that verify the model of transient condition in such an electric circuit. The model is suitable for analyzing the transmission process in single-phase machines which, in order to start, need connected parallel capacitor that will help two-phase work.
