Pazeev A. A single phase converters of a variable voltage in constant with power factor correction and galvanic connected by an input and output.

Object of research: single-phase converters of a variable voltage on constant with power factor correction and galvanic connected by an input and output. The purpose of research: development of theoretical bases of construction of converters of a a variable voltage on constant with power factor correction, creation of models and techniques for research of electromagnetic processes and account of parameters of converters, development of new devices and systems of the power supplies. Methods of research: analytical methods of the theory of electrical circuits, methods of mathematical and physical modeling, methods of the harmonious analysis. Theoretical and practical results and novelty: the new principle of construction of a power part of single-phase converters of a variable voltage on constant with power factor correction and galvanic connected by an input and output is offered and developed new circuit decisions is offered which realize this principle; Is developed new mathematical models and techniques of definition of optimum parameters of converters, which permits to spend the analysis of electromagnetic processes and provides the minimal meanings of THD of an input current; is developed the recommendations for improvement of dynamic properties of converters and quality of electrical energy on an input of single-phase and three-phase converters at presence of pulsations of an output voltage. A degree of introduction: are used in SRI "Quantum" at creation of systems of the power supplies of judicial radio electronic complexes and in educational process in NTUU "KPI". Sphere of use: three-phase systems of the power supplies with improved EMC.
