Abstract
Issues of analysis of processes in electronic voltage boosters of asynchronous type with series circuit of main or pilot arcs are considered. They have configuration of forming circuit, in which capacitive storage and inductance of primary winding of pulse step-up transformer have series connection, and switching key of the circuit is parallel. Part 2 of the work provides for the results of analysis of circuits of increased voltage pulse generators, forming asynchronous exciters and stabilizers of arcing. Description is given to circuit solutions and issues of analysis of charge-discharge circuit of asynchronous exciters and stabilizers of arcing, built based on method of resonant pumping, are reflected. Analysis of processes in the circuit of asynchronous exciters and stabilizers of arcing is carried out using solutions of the equations known in theoretical electrical engineering. Engineering procedure is proposed based on these solutions for calculation of main components in functional assemblies of asynchronous exciters and stabilizers of arcing and recommendations of selection of their element base are given. 29 Ref., 2 Tables, 6 Figures.
 
Keywords: arc and plasma welding, asynchronous exciters and stabilizers of arc, generator of increased voltage pulses, pulse transformer, cores, ferrites, sprayed iron, device for input of high-voltage pulses, resonant pumping
