REACTOR GROUP, SWITCHED BY THYRISTORS Russian patent published in 2017 - IPC H02J3/18 

FIELD: electricity.

SUBSTANCE: reactor group, switched by thyristors, consisting of two parallel connected to the reactor group terminals branches, each of which comprises a series connection of the reactor and the bidirectional thyristor switch, supplemented by a third parallel branch comprising the serial connection of the reactor and the bidirectional thyristor switch, and in each of the three parallel branches reactor group in series with the reactor and the bidirectional thyristor switch additional reactor and bidirectional thyristor switch are introduced in such a way that one and of reactor terminals and auxiliary reactor are connected with opposite terminals of the reactor group, and the total connection point of the bidirectional thyristor switch and additional bidirectional thyristor switch is coupled, respectively, with the same common connection points of the bidirectional thyristor switches and additional bidirectional thyristor switches of the remaining branches by one of the branches via auxiliary bidirectional thyristor switches.

EFFECT: properties and the reactor group parameters amplification, the controlled current discreteness levels increasing, the increasing of the electrical energy quality in case of current control, device simplifying in general at the expense of the high-order harmonic filters exclusion from the composition, reduction of the installed capacity of the equipment included in the reactor group.
