FIELD: electric engineering. SUBSTANCE: three single-phase inverters provided with control systems are used at control circuits of three-phase transformer. The inverters provide regulation of phase of output voltages of inverters in any phase for desired angles α, at which value of output voltage and value of consumed reactive power are kept at preset level. Single-phase voltage transducers and single-phase reactive current transducers are applied as well, which provide automatic balancing of three-phase system of output voltage in combination with inverters control systems at maximal power coefficient of the network. EFFECT: stability of output voltage; improved balancing of three-phase system. 4 dwg
