Synchronization of control systems of several parallel-connected autonomous inverters of voltage supplying from one network and realization of mutual shift of key management signals for compensation time allows to realize the effect of mutual compensation of higher harmonics of input currents, which achieves a significant improvement of the input pulsation coefficient and the harmonic distortion constant constant current. The dependence of additional power losses in the active resistance of the network from the higher harmonics in the function from the harmonic distortion load current is established.
