FIELD: electric engineering.
SUBSTANCE: method for control of parallel voltage inverter consists in the fact that instantaneous voltages are measured on valves, compensating and filter capacitors, pulse sequences of rectangular pulses are generated with duration of 0.5 T, where T - is period of output alternating signal of inverter, permit signal is gnerated at the moment of equality between instantaneous voltages at compensating and filter capacitors, with generated permit signal they generate and supply signals of control to according valves, and they are connected at the moment of equality of instantaneous voltages at valves to zero level, permit signal is collected, as well as control signals, and valves are disconnected at the moments of time specified with cut of rectangular pulses of pulse sequences.
EFFECT: increased reliability of parallel voltage inverter operation.
