Larchenko B. Powerful rectifying complexes with the autotransformer phaseshifting elements of hexagonal and quasi-hexagonal types

Object of research: the powerful rectifier complex. The purpose of research: further development of the theory of powerful rectifier complexes with the autotransformers of hexagonal and quasi hexagonal types by establishment of intercommunications between their elements. Methods of research: the theory of electrical circuits, fundamental theory of the linear and nonlinear systems, method of equivalent sources, method of fundamental harmonic, method of harmonic analysis and mathematical modeling. Theoretical and practical results: the new methods of calculation processes of distributing of currents and powers in the circuits of rectifier complex are developed; angular correlations and calculation dependences for the installed capacity of autotransformer elements of rectifier complex are first got ; new conformities to the law of change of total harmonic distortion of current are got from the phase-shift angle in the autotransformer elements of complex, allowing to choose the optimum value of this corner for providing of most compactness of complex; the new constructions of three-phase-two-phase autotransformer elements with the improved metric indexes are developed. Degree of introduction: are used in educational process CSTU and are recommended for use in development LLC "КП ЭНРИ", Kiev and "MIRUS International Inc", Toronto. Sphere of use: powerful rectifier complexes.
