The object of the study is a two-transformer phase-shifting device with a span of adjustment of the angle of phase shift \(\psi =0^\circ - 60^\circ\). In order to determine the energy characteristics of the investigated device, it has been put the scope to study the regime's parameters, performing adjustment of the angle of phase shift. This was made possible due to the use of the thyristor key for 10 positions and the low of it’s switching. The model was developed for a series of computational experiments for the cases of: idle, short circuit and loaded regime. A comparative analysis of the technical characteristics of the studied device, with the phase-reversing transformers investigated earlier has been carried out. The novelty of the work consists in the development of a scheme of a two-transformer phase regulating device. The additional winding of the magnetizing transformer was connected on an opposite side to the winding of the phase-shifting transformer. It has been achieved a reduction in the value of the magnetic induction in the core, as well as an increase of the stability in the process of adjusting the angle of phase shift. The analysis of the obtained characteristics of the device made it possible, by comparison with the available variants of existing circuits, to conclude that the developed one was of increased technical efficiency. The proposed technical solution decreased the installed capacity of the equipment, which in turn lead to a reduction of the weight and size indices and, as a consequence, of its cost.
