THREE-PHASE VOLTAGE AC/DC CONVERTER Russian patent published in 2014 - IPC H02M7/06 

FIELD: electricity.

SUBSTANCE: invention relates to the field of conversion technologies and can be used for power supply of DC consumers. The three-phase voltage AC/DC converter, containing power transformer with two groups of identical secondary windings, three-winding current balancing reactor and six valves, connected into the closed ring through windings of the current balancing reactor, and each phase of one secondary winding through the valves and the winding of the current balancing reactor is connected with opposite phases of the second secondary winding, it has two groups of valves, one of which consists of three valves, connected together by anodes (anode group), and another one - from three valves, connected together by cathodes (cathode group), meanwhile free cathodes of the first group are connected to phases of one secondary winding, and free anodes of the second group are connected to phases of the second secondary winding, and to the common point of anodes and cathodes of these valves the load is connected. The secondary windings of the converter can be connected both in star, and in delta circuit. The load can be connected also to zero points of stars. The technical result is achieved at the expense of increase of a stationary value of component and frequency of pulsations up to 12.

EFFECT: improvement of quality of rectified voltage.
