The paper presents a review on the problems of the analysis of autotransformer discrete alternating voltage regulators. Most often the discrete regulation of AC voltages is achieved by power electronic converters based on a transformer (autotransformer) and switching by the means of controllable semiconductor switches.

The present work is dedicated to the comparison between precise and approximate non-linear models of autotransformer discrete alternating voltage regulator with changing input voltage and commutation angle of the semiconductor switches and to the vector measurements in an autotransformer discrete voltage regulator.
