Revko A. Quasi-resonant pulse converters for systems of precision electric drive with the direct current motor

The object of research: quasi-resonant pulse converters, with switching at a zero current (QRC - ZСS) with a load - direct current motor (DC-motor). The purpose of research: further development of the theory both practice QRC - ZСS and development, on this basis, guidelines on making new converters with heightened quality for usage in the precise electric drive of a direct current. Methods of research: the theory of electric circuits, principles of the fundamental theory of linear and nonlinear impulse systems, maximum principle Pontryagina, mathematical and physical simulation. Theoretical and practical results and innovations: first time the analysis of electromagnetic processes in a QRC – ZСS with a load DC-motor is presented, and the level mutual influence of parameters DC-motor and QRC - ZСS is defined; the new analytical associations of an output signal of a QRC - ZСS control system, optimum on speed are obtained; the experimental model a full-wave reversal QRC - ZСS with a digital system of control is developed. A subject and degree of the application: results are implemented in CSTU and also are recommended to usage in developments SSIMF «SOLING» and CheZaRa Corp.. Effectiveness of implantation: performances of the electric drive and energetic efficiency improvement. The sphere of application – the precise electric drive of a direct current.
