DEVICE TO CONTROL SERIALLY CONNECTED THYRISTORS Russian patent published in 2012 - IPC H02M7/00 

FIELD: electricity.

SUBSTANCE: in a device for control of serially connected thyristors a single primary winding of pulse transformers is arranged in the form of m conductors with low voltage insulation, arranged in an introduced insulation tube, stretching inside cores of pulse transformers, the number of turns of secondary windings of pulse transformers is increased m times, and section of cores in pulse transformers is reduced m times. Conductors of the single primary winding of pulse transformers are connected to each other at least in accordance with a serial circuit.

EFFECT: higher reliability of a control device by thyristors connected in series, simplified design and reduced dimensions of pulse transformers.
