TWENTY-FOUR-PULSE CONVERTER Russian patent published in 2013 - IPC H02M7/12 

FIELD: electricity.

SUBSTANCE: twenty-four-pulse converter comprises two three-phase transformers, coils of secondary windings of all phases in which have taps from the half of turns and are connected into one circuit in the form of a "dodecadron", voltage, between tops of which a twelve-phase system of voltages is created, and valves are connected into two groups - anode and cathode. In the anode group of valves the anodes are connected into one unit representing a single pole at the DC side, and in the cathode group of valves the cathodes are connected into a different unit, representing another pole on the DC side. Each valve of the anode group by its cathode is connected to one top of the "dodecadron" of secondary windings, and each valve of the cathode group by its anode is connected to the middle point of one of coils in the secondary windings of the transformer.

EFFECT: higher efficiency of a converter, reduced dimensions, weight and cost.
