摘要

FIELD: electricity.;SUBSTANCE: device comprises a command unit and an inductive component consisting of a primary load member and a control unit for the latter, and there is an additional integrating filter; the controlled current source is used as the primary load member, which first and second powered terminals are the control input respectively as well as the first and second powered terminals of the above primary load member, a multiplier with two input terminals and output terminal being the first and second input terminals and output terminal of the control unit is used as the control unit. The first and second input terminals of the above integrating filter are connected respectively to a neutral unit of the electric mains and to the ground, and the first and second output terminals of this filter are connected respectively to the second input of the control unit of the primary load member and to the ground.;EFFECT: improving specifications of the claimed device due to reduction of weight, power and noise level of the control unit, increasing its operating speed and efficiency factor, improving noise emission and Q-factor of the primary load member in comparison with performance of primary load members made as reactors with smooth regulated air gap.;4 cl, 11 dwg
