Rudenko Y. Fundamentals of the calculation theory of multi-interval processes in semiconductor converters with high-potential units for electro vacuum equipment.

Object of research: electromagnetic processes in high-frequency semiconductor converters of electric energy parameters for power supplies of vacuum equipment. Purpose of research: develop new methods and mathematical models for calculating multi-interval electromagnetic processes, taking into account the constant and pulsating components of variable states in high-frequency semiconductor converters for electric vacuum equipment, aimed at increasing their electric power and technical parameters. The research methods are based on the theory of calculating linear electrical circuits, the classical method of calculating transients, the method of averaging in the state space, the theory of differential equations, the theory of automatic control, and methods of mathematical modeling. Theoretical, practical results and novelty: an important scientific and applied problem has been solved to develop the theory of high-frequency semiconductor converters with high-potential units for electrovacuum equipment. New methods and mathematical models have been developed for calculating multi-interval electromagnetic processes, taking into account their constant and pulsating components in converters with high potential units, which allowed to reduce the complexity of calculations, reduce the volume of mathematical transformations and thus increase the speed of calculations and their efficiency. Subject and degree of implementation: the main results of the work in the form of scientifically based recommendations for the development and creation of converters for power supplies of technological equipment were introduced at the A.V. Dumansky Institute of Colloid Chemistry and Water Chemistry (NAS of Ukraine), at the G.V. Kurdyumov Institute of Metal Physics (NAS of Ukraine), at the enterprise “SVP“ Kiev TPP ”PAT“ Kyivenergo ”. Scientific results are used in the educational process of NTU of Ukraine "KPI". Implementation efficiency: improvement of electrical and technical indicators of power supplies of electrotechnological equipment. Sphere of use: power supplies for vacuum equipment
