This article presents the results of the study of the automatic regulator of the stabilizer. In the work, the study of the output voltage of an autonomous inverter was carried out by introducing a digital form of setting the insert of a stabilized voltage and a digital form of comparison with a reference voltage. The achieved high accuracy of voltage stabilization does not depend on the choice and careful adjustment of the elements. This made it possible to achieve stability of the voltage generator and the width of the sensitivity zone. The voltage regulation of the converter is carried out by changing the level setting associated with the shift of the insensitivity. The speed of development of a given control angle depends on the pulse repetition rate of the generator, which is limited only by the frequency properties of integrated circuits. Improvement of the control system of the autonomous inverter made it possible to increase the accuracy of stabilization of the output voltage of the inverter, which made it possible to simplify the adjustment of the control system for easy coordination with other software elements. Studies have shown that the voltage regulation of the converter is carried out by changing the level setting associated with a shift in the dead zone. The speed of development of a given control angle depends on the pulse repetition rate of the generator, which is limited only by the frequency properties of integrated circuits. And with the equality of the frequencies of the pulse generators, the minimum width of the dead zone and the change in the load from nominal to no-load, the stabilization accuracy of the output voltage of the inverter was 0.5%.
