Namestnik S. Special modes in series RLC - circuit with the reverse commutator.

Object is a series RLC-circuit with the commutator. The purposes are the further development of the electromagnetic processes theory under use in the special modes of RLC-circuit with the commutator and development of recommendations for making new devices on its basis. The methods are the theory of electrical circuits, mathematical and physical modeling. Novelty is that theoretical researches of the transitive and steady-state modes in a RLC-circuit have received the further development; the new criteria of an estimation of transients duration are developed; the earlier unknown conditions are determined, at which the traditional resonant filter transforms into the monoharmonic active filter; for the first time it was investigated the influence of fluctuations of network frequency, parameters of a circuit and commutator on amplitude and phase of (-th harmonic on the active filter input. The results the basic spects of the electromagnetic processes theory under use in the special modes of RLC-circuit with the commutator are developed and the new scientifically proved theoretical and practical results are received. The executed researches have found applications in the educational process in NTUU "Kyiv polytechnical institute", at research engineering performance on NANU subjects, manual, which is introduced into educational process is published. Area is designing of new devices for improvement of electrical energy quality in electric power supply systems and creation of power supplies of technological installations.
