FIELD: electricity.
SUBSTANCE: invention may be used to control or stabilise voltage of power and converting transformers, in particular for supply of individual loads in networks with unstable parametres. It is proposed to control voltage alternately in zones of current and voltage match and non-match. Besides voltage should be reduced first in zones of current and voltage signs match by increasing switching angle and second in zones of current and voltage signs non-match by reducing switching angle, and pressure increase shall be executed in reverse order.
EFFECT: expanded range of control in case of active-inductive, active-capacitance and recuperative loads, and in idle running of transformer.
