SINGLE PHASE DC CONVERTER Russian patent published in 2015 - IPC H02M7/00 H02M7/162 

FIELD: electricity.

SUBSTANCE: device contains a traction-feeding transformer with three secondary winding sections, a rectifying and inverting converter with eight arm of series connected thyristor and a diode forming a bridge circuit, a load comprising series connected and engine and an inductive resistance, a zero thyristor connected parallel to the load and connected with it zero thyristor control unit connected to the first section of the secondary winding of the transformer and containing mutually connected the voltage sensor, the rectifier, the shaper of clock pulses, the time-pulse generator, the comparator, the univibrator, the traction-recuperation mode switch and "AND" element.

EFFECT: decrease of the engine power consumption due to increase of average value of the rectified voltage at the output of the rectifying and inverting converter due to forming in the traction mode in each zone of adjustment of zero values of the rectified voltage during the time.
