Issues of circuit engineering and analysis of processes in electronic voltage boosters of asynchronous type with series switching-in of main and 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 switched on in parallel to this connection. The first part of work describes circuit engineering solutions for imbedded asynchronous exciters and stabilizers of arcing process for charging devices based on key scheme with dosing reactor and diode-capacitor voltage multiplier. Analysis of arcing process in circuits of these functional assemblies of asynchronous exciters and stabilizers was performed using equations known in theoretical electric engineering. Engineering procedure of design of main components of charging devices for asynchronous exciters and stabilizers of arcing process as well as recommendations on selection of their element base are proposed based on equation solutions. 28 Ref., 3 Tables, 9 Figures.
