REACTOR GROUP, SWITCHED BY THYRISTORS Russian patent published in 2017 - IPC H02P13/06 

FIELD: electricity.

SUBSTANCE: reactor group, switched by thyristors, consisting of three parallel-connected to the terminals of the reactor group branches, each of which comprises an in-series connection of the reactor and anti-parallel connected thyristors, is equipped with additional anti-parallel connected thyristors. The anti-parallel connected thyristors outputs of two of the three branches are connected together and attached to one of the reactor group terminals, and the anti-parallel connected thyristors output of the third branch is connected to the second reactor group terminal, at the same time, the parallel-connected branches reactors are provided with the transitional internal windings terminals, and the reactor transitional internal winding terminal in the third branch is connected to each of the transitional internal windings terminals of the first and second branches with the help of the additional anti-parallel connected thyristors, respectively.

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.
