FIELD: electrical engineering.
SUBSTANCE: invention relates to electrical engineering and can be used in power supply systems. Transformer consists of an E-shaped magnetic conductor, primary and secondary windings, three hollow rods filled with magnetic fluid, connected by means of a pipeline through three comparators and three reversing switches with three hydraulic pumps and a reservoir containing magnetic fluid. Inputs of the three comparators are connected to the phases of the secondary winding, respectively. In the wall of the magnetic conductor there are holes through which the inner cavities of the rods of the magnetic conductor are communicated with the atmosphere.
EFFECT: broader functional capabilities of the transformer by providing independent measurement and independent automatic smooth control and maintenance of voltage at all outputs of the secondary winding.
