This article examines the processes occurring in the input circuits of a universal AC control system. The calculated ratio of the power flow control algorithms between networks, provided consumption given the current nature of any nature in the generation of power. The dependences of the calculated ratios.
Keywords: a universal system of alternating current control; power flow control; vector diagram; Power network voltage inverter, active rectifier, capacitive drive.
