SINGLE-PHASE ALTERNATING-TO-DIRECT CURRENT CONVERTER Russian patent published in 2010 - IPC H02M7/155 

FIELD: electricity.

SUBSTANCE: converter includes ten controlled valves and three uncontrolled valves, single-phase transformer with primary winding and two sectional secondary windings having the outputs from beginnings, from connection points of sections and from ends; at that, six-valve ring with connections of valves is formed of six controlled valves with the same electrodes; the rest controlled valves and two uncontrolled valves are combined into two three-valve stars opposite each other, in each of which one of valves is uncontrolled, and common connection points of the same electrodes of valves of three-valve stars form two heteropolar outputs of the device, to which there connected is load; at that, the same outputs of two-sectional windings are connected to connection points of electrodes of valves, which are diametrically located in valve ring; at that, two controlled valves diametrically located in valve ring connect extreme opposite outputs of two-sectional windings, to which they are connected with free electrodes in series with the above valves of the ring along one of controlled valves of three-valve stars; at that, free electrodes of uncontrolled valves of three-valve stars are connected to connection points of sections of those two-sectional windings to extreme outputs of which there connected are electrodes of controlled valves of three-valve stars, which are similar to them, and in series with uncontrolled valves of three-valve stars to middle outputs of two-sectional windings there connected is the rest uncontrolled valve.

EFFECT: single-phase alternating-to-direct current converter has high efficiency.
