METHOD AND DEVICE OF MATCHED CONTROL FOR SERIES GATE GROUPS OF VOLTAGE CONVERTER Russian patent published in 2020 - IPC H02J3/36 H02M7/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the field of electric engineering, in particular, to the control for the in-series connected voltage converter voltage groups. Method is realized which includes: distribution of reference value of total DC voltage or reference value of full active power on side on which said series gate group of voltage converter is located, in accordance with total number of in-series connected voltage converter voltage groups; for the DC voltage control side – the DC voltage of each valve group is controlled in accordance with the assigned DC voltage reference value for each valve group; for active power control side – active power of each valve group is controlled in accordance with assigned reference value of active power for each valve group and based on addition of value of compensation of active power of valve group.

EFFECT: achievement of DC voltage balance of each gate group of voltage converter.
