DEVICE FOR INTERPHASE CURRENT DISTRIBUTION (VERSIONS) Russian patent published in 2017 - IPC H02J3/26 H02H3/347 H02M7/155 

FIELD: electricity.

SUBSTANCE: first version of the device for interphase current distribution contains two single-phase transformers, the intermediate output of each winding is connected to the first terminal of the consumer, and the outermost terminals - to the phase input terminals. The second consumer terminal is connected to the common point of the two end terminals of the mentioned windings, the number of turns of each of which is divided by an intermediate terminal into two unequal sections. Sections of windings with a large number of turns are connected to the phase input terminals. The second version of the device differs from the first version in that the intermediate output of each winding of the transformer divides its number of turns into equal parts. According to the first version, the recovery range extends from a value in excess of half of the energy consumed to a value limited only by the structural complication of the MRI transformers associated with a pronounced inequality in the cross-sections of each phase winding section. According to the second version, the recovery is equal to half the energy consumed. The cross-sections of each phase winding section are equal, which simplifies their production. Magnetic cores of MRI transformers can have different configurations, including a twisted band-shaped ribbon.

EFFECT: expanding the range of energy recovery in case of use for single-phase consumers.
