Abstract: The Alternative Current voltages have discrete regulation and the regulation is achieved by power electronic converters based on autotransformers and switching. We have used vector analysis and measurements in autotransformer discrete voltage regulator. These regulators change to approximated non-linear models with change of input voltage and various angles in the semiconductor switches.
