A study of a single-phase thyristor inverter

Abstract

The results of studying the switching processes in a single-phase thyristor inverter operating at a low-voltage controlled thyristor rectifier with constant output current are given. Depending on the angle of rectifier voltage regulating, three switching modes are identified and considered. The maximum values of currents and voltages are defined for each of the modes. The waveforms of currents and voltages are given. It is shown that the nature and duration of the inverter switching processes depend strongly on the angle of rectifier regulating, which is especially to be considered when the inverter operates at higher frequencies.
