FIELD: electric machine engineering, namely inductor generator plants, possibly used as autonomous electric power sources in transport vehicles, in wind-driven electric power installations, electric power units for different manufacturing processes such as electric arc welding by pulsating high-frequency constant-value current. SUBSTANCE: plant includes power inductor DC generator, power inductor AC generator 1 with excitation winding 2 and with unit 3 of power rectifiers; exciting AC generator 4 with unit 5 of rectifiers. Generator 4 is connected through unit 5 of rectifiers and unit for controlling output voltage with DC excitation winding 2. Unit for controlling voltage output between power terminals of inductor generator plant includes welding current pickup 6; welding voltage pickup 7; threshold electric current device 8; reference voltage shaper 9; voltage comparator 10; pulse width modulator 11 and pulse type voltage stabilizer 12. Output of welding current pickup 6 is connected through threshold device 8 with inhibiting inlet of voltage comparator 10 whose control inlets are connected with output of welding voltage pickup 7 and through reference voltage shaper 9 - with output of unit 5 of rectifiers of exciting generator 4. Output of comparator 10 is connected through pulse width modulator 11 with control inlet of pulse type voltage stabilizer 12. Output of unit 5 is connected in addition through voltage stabilizer 12 with excitation winding 2 of inductor generator 1. EFFECT: lowered labor consumption for pulsating electric arc welding by means of consumable electrode. 1 dwg
