FIELD: engines and pumps. ^ SUBSTANCE: inverter generator comprises dynamoelectric generator unit that includes generator unit, converter (20) to convert variable current into constant current, inverter to convert constant current into variable current furnished with gate elements to supply electric load, inverter control device to control gate elements by PWM-signal generated using reference sine signal with wave shape of required output voltage and carrier signal in every control cycle (step) defined by carrier frequency. It generates preset frequency variable current. Inverter control device varies carrier frequency in compliance with inclination (designated, for example as D 1, 2) of reference sine signal, and, in particular reduces carrier frequency with reduction of reference sine signal inclination. ^ EFFECT: ruling out of liner distortions and lower operating costs. ^ 6 cl, 6 dwg |
