FIELD: electricity.
SUBSTANCE: invention is related to the field of electric engineering and power electronics and can be used for design of alternating-current generation systems or AC uninterrupted power supply systems with a voltage inverter. The claimed method for control of the voltage inverter lies in shaping of three control signals, shaping of a reference bipolar signal, generation of control pulses for the voltage inverter gates when zero level is exceeded by the difference of the reference bipolar signal and control signals, frequency of the reference bipolar saw-tooth signal is determined by a sum of the determined frequency value and a random frequency value with zero mathematical expectation and mean-square deviation, less than the determined value of frequency.
EFFECT: reducing weight and dimensions of the generation system, improving quality factors of the generated electric energy and electromagnetic compliance with the load (consumers) due to reduction of the mixed harmonics amplitude.
