FIELD: electric power industry.
SUBSTANCE: invention relates to the field of electric power engineering and can be used for arrangement of parallel operation of three-phase voltage inverters. Synchronization of reference signals of pulse-width modulation generators of voltage inverters, operating in parallel to a common load, is carried out by means of cyclic transmission via digital serial interface from master inverter to slave inverters of global messages containing synchronization flags, upon receipt of which the slave voltage inverters reset the reference signals of the pulse-width modulation generators.
EFFECT: high accuracy of synchronizing output voltages of inverters operating in parallel for a common load.
