The article is devoted to the principle of creating a technical means to improve the electromagnetic compatibility of three-phase rectifiers in AC supply networks. The principle of constructing the circuit solution of this technical device is described and the calculated expressions for its implementation are presented on the basis of transformer converters of the number of phases and the connection of their windings into a “sliding delta”. This solution allows implementing a controlled mode of increased equivalent pulsation of rectification and providing high-energy performance in the supply network by regulating the phase shifts of three-phase voltages supplying three-phase rectifiers, which is confirmed by a series of model experiments.
