FIELD: electric engineering. SUBSTANCE: commutator of stepping transformer is designed as converter of amplitude and voltage phase with direct current circuit and double-direction power transfer. In stepping-up mode device receives power from load circuit, in stepping-down mode it outputs voltage to circuit. Said modes are controlled by means of inverter phase control unit and separate control system for reverse rectifier together with current, voltage and reactive power detectors. EFFECT: increased compensation range, decreased weight and size. 1 dwg
