FIELD: power engineering.
SUBSTANCE: method consists in control pulses generation by power switches of inverter using phase synchronisation of system voltage and current. According to this method before voltage and current phase synchronisation, voltage sensor signals are processed by phase converter, and after phase synchronisation output signals of phase synchronisation unit are multiplied by set current signal of storage capacitor voltage regulator, processed by phase converter, then compared with measurement signals of nonlinear load current, set and actual inverter current, and obtained as a consequence of this unbalance signal is supplied to inputs of relay regulators.
EFFECT: improvement of electric energy quality in system with nonlinear load due to lowering harmonicity deformation factors.
