Abstract
Considered are the issues from analysis of formation of high-voltage pulses, injected into interelectrode gap for initial arc ignition and its re-ignitions, in electronic devices with independent power supply and series connection to electric circuit of main or pilot arc, where all the elements of forming circuit are also connected in-series. The analysis of oscillating processes in the forming circuit is carried out using the solution of known linear differential equations of second degree with non-zero initial conditions. Engineering procedure based on these solutions was proposed for calculation of all components of the forming circuit in electronic devices with independent power supply for arc excitation, as well as recommendations on selection of their element base were given arising from the experimental data and experience of designing, industrial manufacture and operation of such devices. Variants of circuit solutions for oscillating constituent of electronic arc exciters with independent power supply and devices for control of switching cell of the forming circuit were described. 34 Ref., 6 Figures.
