Zhemerov G.G., Kolesnik V.J. 19 Analysis of processes in an active rectifier - current source in asynchronous machines start- ing system. Application of an active rectifier - current source in the starting system of asynchronous ma- chines on the basis of a current source inverter is considered in the article. Expressions for determi- nation of voltages and currents in the network filter of the active rectifier – current source elements are obtained. Output voltage waveform of the active rectifier is analyzed. Key words – active rectifier - current source, current source inverter, network filter. Klymenko B.V. 26 Electrical and magnetic devices: terminol- ogy of International Electrical Dictionary. The paper considers a number of problems concerning introduction of terms and definitions from International Electrical Dictionary (IED). We begin publishing a nonofficial translation of an IED part, namely, part 151 - Electrical and mag- netic devices, with the author's comments and ex- planations. Key words – International Electrical Dic- tionary terminology introduction, nonofficial translation. Makogon S.A. 33 Simulation of unidirectional magnetic forces in a coaxial-linear synchronous vibrator with an asymmetrically positioned armature. Unidirectional magnetic forces and traction characteristics for a coaxial-linear synchronous vibrator with a toothed and toothless stator are analysed by a finite element method. Key words – FEM, linear vibrator, mag- netic forces. Milykh V.I., Tkachenko S.V. 36 Force interactions in a linear electric motor for seismic vibrations sources. Force interactions in a linear pulse electrody- namic motor for sources of seismic vibrations are considered. The motor differs in its cylindrical electromagnetic system and its strong magnetic saturation. Contribution of electrodynamic and magnetic constituents to the total traction force is revealed. Force behavior as function of the relative position of the armature and the reactor as well as mmf of their windings is specified.

High Electrical and Magnetic Field Engineering Baranov M.I. 51 A ball lightning, a powerful natural mo- lecular integrator of atmospheric electricity. A new hypothesis of the origin and a theory of the electrophysical phenomenon. A new physical and mathematical model and a new hypothesis of a probable origin, formation and existence in the air atmosphere of such a natu- ral phenomenon as a ball lightning (BL) are intro- duced, based on electric dipoles of water micropar- ticles (molecules) and their electrostatic coupling with the negatively charged nucleus of lightning. Analytical estimations of possible levels of the strength of ultrahigh electric field inside and out- side of the BL active spherical zone, as well as electric potentials, density, and absolute indices of electric energy accumulated by BL are executed. Key words – ball lightning, physical and mathematical model, origin, formation and ex- istence, analytical estimations. Batygin Yu.V., Bizhar Magid, Serikov G.S. 60 Experimental investigation of inductor sys- tems for angled bend forming on sheet work- pieces. Conducted experimental investigations of in- ductor systems for angled bend forming on sheet work-pieces has confirmed theoretical results reli- ability and, correspondingly, practical workability of inductor system designs developed for perform- ing the given technological operation. Allowance for finite lateral size has shown that the real width of current-conductors essentially decreases magni- tudes of excited fields and pressures. Thus, chang- ing a point model to a strip one gives decreasing the magnetic field intensity by maximum ∼ 33% and pressures ∼ 89%. Key words – experimental investigations, inductor systems, angled bend forming, sheet work-pieces. Batygin Yu.V., Chaplygin E.A., Chernogor T.T. 64 Experiments with induction inductor systems for magnetic pulse attraction of sheet metals.

The technical essence of the suggestion consists in specifying a geometrical shape of an additional screen what permits decreasing a distance between interacting subjects. Testing an experimental model has shown its practical workability. Key words – induction inductor system, in- ductor, auxiliary screen, work instrument. Petkov A.A. 68 Calculations of tolerance of high-voltage test device digit circuits.
