TWO RECTIFIER UNITS CONTROL METHOD Russian patent published in 2018 - IPC H02M7/19 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the field of electrical equipment and can be used in the DC inserts. There are two power units, into each of which two bridges are in-series included, by the phases connected to the transformer windings with different connection group. Performing the alternate control over belonging to different bridges half-bridges heterogeneous pairs, in which the external and internal half-bridges operate in the same mode. This eliminates the bridges voltages asymmetry.

EFFECT: increase in the energy performance is achieved by reduction of the reactive power consumption.
