Mozharovsky A. Discrete alternating current voltage stabilizers with two-transformer executive structures

Subject of inquiry: discrete stabilizers of a variable voltage on the basis of transformers-switches executive structures. the purpose of work: development of the theory of the executive structures of discrete stabilizers of an alternating current with division of adjustable and nonadjustable powers, development of a method of their account focused on modernization of the decisions. Methods of research: electrical circuit theory, structural – topological and methods of mathematical and physical simulation. Theoretical both practical results and novelty: the theory of designing of discrete stabilizers has received the further development; for the first time are certain of a parity of windings of transformers of the executive structure allowing to realize the law of a choice of factors of transfer according to a geometrical progression and to synthesize topology of structure; is established, that of section of windings of the auto transformer are unequally loaded on a current, in view of that his real settlement established capacity is determined. Subject and extent of a heading: the results of researches are introduced in joint with Institute "Converter" (Zaporozhye) development of the stabilizer of a variable voltage and in blocks of management of half-automatic devices for welding in environment of inert gases the Enterprise "Plasma" (Rostov-na-Donu, Russia). Efficiency of a heading: the stabilizers with the improved technical and economic parameters are created. Sphere of use: means of normalization of parameters of the electric power of various functional assignment.
