TWENTY FOUR-PHASE CONVERTER OF THREE-PHASE-VOLTAGE-TO-CONSTANT VOLTAGE Russian patent published in 2014 - IPC H02M7/162 

FIELD: electricity.

SUBSTANCE: proposed converter serves to supply DC consumers that demand high quality conversion at various levels of the rectified voltage. The suggested converter comprises four symmetrical three-phase power sources and five in-sequence gate groups, the outermost groups consist of three gates coupled into anode and cathode gate deltas, which common points form output leads of the device while the remaining three groups are made as six-gate rings with three pairs of diametrical connection points of the same gate electrodes. Adjacent gate rings are connected at three points each formed by a free pair of the point of connection between the electrodes in the adjacent ring gates. The converter is equipped with twenty one additional gates, gates of the six-gate rings are made as controlled ones, and three additional gates are also made as controlled ones, while the remaining ones are uncontrolled.

EFFECT: larger functional capabilities.
